Build a Twitter-like site with CodeIgniter and jQuery Part 2

Wez Pyke — Sun, 14 Feb 2010 19:58:15 +0000

Don't forget to check out part 1 if you have no read it.

In the second part of this 5 part tutorial series on how to build a Twitter-like website, we will be creating a signup form so that users can register to our website.

We will be adding records to the database that we created in part 1 and creating validation rules to make sure that the user didn't put any invalid data into the form.

Change the base url

Navigate to ci_twitter->system->applications->config->config.php.
Change:

$config['base_url'] = "http://example.com/";

To the path to where CodeIgniter is. On my machine it would be:

$config['base_url'] = "http://tutorials:8888/ci_twitter/";

Create the controller

We need to create a main controller for things such as the home page, sign up page, login page, etc. Go to ci_twitter->system->application->controllers then in the controllers folder create a file called main.php.

Inside our main controller we now need to define the class and the functions inside it.


class main extends Controller {
 
	function index()
	{
		$this->load->view('main/index');
	}
 
	function signup()
	{
		$this->load->library('form_validation');
		$this->load->helper(array('form', 'url'));
		$this->load->view('main/signup');
	}
 
	function signin()
	{
		$this->load->library('form_validation');
		$this->load->helper('form');
		$this->load->view('main/signin');
	}
 
}
 
?>

If we were to go to http://localhost/ci_twitter/index.php/main/ then we will see a blank page.

Create the views

Before we can see anything we need to create a folder for the functions in our main controller. Go to ci_twitter->system->application->views. Inside the views folder create another folder called main. In the main folder we will create files for each function that we have in the main controller.

Create these files in the main folder we created:

index.php
signup.php
signup_success.php
signin.php

Go to index.php and enter Hello World. Now if you go to http://localhost/ci_twitter/index.php/main/ you will see Hello World.

The next thing to do is to add a form and text fields so that people can input data. For the sign up page the html is done in the signup.php view file. The validation and processing is done in the main controller inside the signup function.

Add the following code to the signup.php view:

Sign up

echo validation_errors();
echo form_open('main/signup');
?>
 
Full name:  

Username:  

Password:  

Email:

Then add this inside signup_success.php:

Your account was created,  echo anchor('main/signin', 'login here'); ?>

This is all that we need to do for the sign up view for now. Validation rules is what we will do next in the main controller for sign up.

Validation

When doing form validation all of the validation takes place inside of the controller. For now we will set basic validation rules for each field within the form.

In the main controller replace the code for the signup function with:

	function signup()
	{
		$this->load->library('form_validation');
		$this->load->helper(array('form', 'url'));
 
		$this->form_validation->set_rules('name', 'Name', 'required|min_length[5]|max_length[50]|trim|xss_clean');
		$this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[50]|trim|xss_clean');
		$this->form_validation->set_rules('password', 'Password', 'required|min_length[5]|max_length[50]|trim|xss_clean');
		$this->form_validation->set_rules('email', 'Email', 'required|min_length[5]|max_length[50]|valid_email');
 
		if($this->form_validation->run() == FALSE)
		{
			$this->load->view('main/signup');
		} else {
			$this->load->view('main/signup_success');
		}
 
	}

If you go to the sign up page now you should see that all the validation code works like it should. Now we will add a model so that we can add the user to the users table.

Create user model

Go to the model folder and create a file called User_model.php.

Insert this code into the model:


class User_model extends Model {
 
	function user_exists($username)
	{
		$this->db->select('username');
		$this->db->from('users');
		$this->db->where('user_username', $username);
		$result = $this->db->count_all_results();
		return $result;
	}
 
	function create_user($fullname, $username, $email, $password)
	{
		$data = array('user_fullname' => $fullname, 'user_username' => $username, 'user_email' => $email, 'user_password' => $password);
		$this->db->insert('users', $data);
	}
}
?>

Now we need to load the User_model in the controller.
Insert this code in the signup function:

$this->load->model('User_model');

We also need to add the user if the validation rules are passed:

$this->User_model->create_user($this->input->post('name'), $this->input->post('username'), $this->input->post('email'), $this->input->post('password'));
$this->load->view('main/signup_success');

Part 3

In part 3 we will be creating a login page and functionality so that people can post messages.

Build a Twitter-like site with CodeIgniter and jQuery

Wez Pyke — Fri, 12 Feb 2010 15:39:07 +0000

This tutorial will be the first of a five part series where we will built a social network site similar to Twitter from scratch. We will be using the CodeIgniter framework for the core of the website and jQuery for the effects. In this first part we will be configuring CodeIgniter to display everything correctly and we will also set up a database and connect to it.

Download and configure

Download the CodeIgniter framework from their website. We don't need to download anything for jQuery because we will be loading it directly from Google as it's quicker to load.

Once you have downloaded the latest version of CodeIgniter from their website, unzip it and copy the files to your public_html folder or equivalent. Rename the CodeIgniter folder to ci_twitter.

Now if you go to http://localhost/ci_twitter you should see something similar to the image below.

Database

We now need configure a database to connect to CodeIgniter so that we can use it to insert and retrieve information. Go to phpMyAdmin or whatever you use for MySQL databases. Create a database called ci_twitter.

CREATE DATABASE `ci_twitter` ;

For now we are only going to create a table for the users, in another part we will create other tables when we need them.

users table:

 CREATE TABLE `ci_twitter`.`users` (
`user_id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`user_fullname` VARCHAR( 50 ) NOT NULL ,
`user_username` VARCHAR( 50 ) NOT NULL ,
`user_email` VARCHAR( 50 ) NOT NULL ,
`user_password` VARCHAR( 50 ) NOT NULL ,
`user_protected_updates` TINYINT NOT NULL DEFAULT '0',
`user_location` VARCHAR( 50 ) NOT NULL ,
`user_web` VARCHAR( 50 ) NOT NULL ,
`user_bio` VARCHAR( 160 ) NOT NULL
) ENGINE = MYISAM

Configure CodeIgniter

Now that we have set up our database and have inserted a table we will configure CodeIgniter to connect to it.

Navigate to database.php by going to ci_twitter -> system -> application -> config -> database.php. From here enter the correct information for your database so that it connects.

We need to auto load the database library because we will be using it a lot.

Go to autoload.php in the same folder as database.php.

Change:

$autoload['libraries'] = array();

To:

$autoload['libraries'] = array('database');

The database library will now load every time without us having to put $this->load->library('database'); in every controller.

End of Part 1

This is the end of the first part of approximately five parts.

Part 2

Part 2 will be following tomorrow. In part 2 we will be creating a sign up so that we can add users to the database.

Deep Linking with jQuery

Wez Pyke — Wed, 10 Feb 2010 14:43:43 +0000

You can view a demo and download the resources for this tutorial at the bottom of the post.

Web 2.0 websites have a lot of Ajax functionality, some times when you load a new element of a page you may want the user to be able to click the back or forward button so that they can see the previously loaded content. One method to add this function to a website is to use the jQuery Address plugin with jQuery.

jQuery Address has 4 main methods; init, change, internalChange, externalChange. The init method is what is called when the plugin is initiated. The change method is called when the URL is changed, an element in the page is changed or either the forward or backward button is pressed. The change method has the combined functionality of internalChange and externalChange. The internalChange is only called when a hyperlink inside the page is clicked; externalChange is only called when the URL is changed or the backward or forward button is pressed.

To allow deep linking within your website the only two methods that are required is init and change, you can then use internalChange and externalChange wherever you may need them.

Getting it to work

The first thing that is required of course is that you download the file for jQuery Address. When you have done this copy the jquery.address-1.1.min.js file into the same location as your index.html file.

Now we include jQuery and the jQuery Address plugin, put this inside the head tags in your html file:


<script type="text/javascript">
google.load("jquery", "1.4.1");
script>

The jQuery

The next thing that we're going to do is create a function that will be called when a hyperlink is clicked so that we know what file to load and where to load it. We will call this function loadURL(), it will take one parameter named url.

function loadURL(url) {
	    	console.log("loadURL: " + url);
	    	$("#area").load(url);
}

We have console.log so that when we open up Firebug in Firefox we know which page is being requested. This is useful for debugging if there are any faults with the requested page loading.

We now set the jQuery Address event handlers so we know when to deep link an element within the page.

$.address.init(function(event) {
	        console.log("init: " + $('[rel=address:' + event.value + ']').attr('href'));
}).change(function(event) {
	    	$("#area").load($('[rel=address:' + event.value + ']').attr('href'));
	    	console.log("change");
})

What this code does is retrieves the href attribute from a hyperlink by matching the rel to a hyperlink. We also log when it should have changed so we can see this in Firebug.

The last bit of jQuery that we do will check when a link has been pressed and then call the loadURL() function that we created before.

$('a').click(function(){
	    	loadURL($(this).attr('href'));
});

This is what the head of your file should look like:




	
	TheTutorialBlog.com : jQuery Deep Linking
	
	<script type="text/javascript">
	google.load("jquery", "1.4.1");
	script>
	
 
 
	<script type="text/javascript">
	/*
	$("document").ready(function(){
 
	    function loadURL(url) {
	    	console.log("loadURL: " + url);
	    	$("#area").load(url);
	    }
 
 
	    // Event handlers
	    $.address.init(function(event) {
	        console.log("init: " + $('[rel=address:' + event.value + ']').attr('href'));
	    }).change(function(event) {
	    	$("#area").load($('[rel=address:' + event.value + ']').attr('href'));
	    	console.log("change");
	    })
 
	    $('a').click(function(){
	    	loadURL($(this).attr('href'));
	    });
 
	    });
 
	/*]]>*/
	script>

The HTML

The HTML for this is really basic stuff, we will create two hyperlinks that will load two separate files. We will also create a div element named area, this is where the files will be loaded.


 
 
	Test 1 

	Test 2 
 
 

 
	Load Area:

The name of the file that you want to load goes inside the href tag. You also need to include address:/ inside rel. This is how jQuery Address knows what hyperlinks you want to deep link.

Final words

Cheat sheets: jQuery, MooTools, Prototype

Wez Pyke — Tue, 09 Feb 2010 14:57:33 +0000

Javascript frameworks like jQuery, MooTools and Prototype are being used by almost all developers in web design and web development, and if you're not using them you should be. Frameworks like these make building complex Javascript functionality into websites a breeze with only a few lines of code.

If you want to start using a framework but are not sure which one is for you then you are probably best starting off with jQuery as it is simple to understand yet powerful. You can also use frameworks together, check out my post here.

In this post you'll find cheat sheets that will be helpful to you as a reference when using one of these frameworks and you can't quite remember a function.

jQuery Dropdown Suggestions

Wez Pyke — Sat, 30 Jan 2010 21:36:24 +0000

For this tutorial we are going to create a drop down box similar to the one on the Google homepage when you start typing.

The Markup

The first thing that we must do is create the markup HTML. We are also going to include a stylesheet called style.css, we will create the CSS further down the tutorial.

We need to create an input field and a DIV element, the DIV element is where the suggestions will be displayed.




	
	TheTutorialBlog.com - jQuery Dropdown Suggestions
	


	
	
		Suggestions for ...

The CSS

Create a file called style.css in the same folder.

We are going to give the input field and suggestions DIV rounded corners of 5 pixels. We will also hide the suggestions DIV because it should only be visible when a user starts to type.

	body {
		background-color: #ccc;
	}
 
	.suggestionsinput {
		font-size: 36px;
		-moz-border-radius: 5px;
		-webkit-border-radius: 5px;
		border: 1px solid #999;
		color: #999;
	}
 
	#suggestions {
		-moz-border-radius: 5px;
		-webkit-border-radius: 5px;
		width: 460px;
		background-color: #999;
		position: fixed;
		padding: 5px;
		visibility: hidden;
	}

The jQuery

Load the jQuery library from Google. Place this code below the include of the CSS file in your HTML file.

	
	<script type="text/javascript">
	google.load("jquery", "1.3.2");
	script>

Below this code we will write our jQuery.

Check that the document is loaded.

	<script type="text/javascript">
	$(document).ready(function(){
 
		// Code goes here
 
	})
	script>

When the page is loaded the input field will display "Search", when the user clicks on the input field we want it to be blank so that they can start searching without having to delete the word.

	// clear text from input
	$(".suggestionsinput").click(function(){
		if($(".suggestionsinput").val() == "Search")
		{
			$(".suggestionsinput").val("");
		}
	})

When the input field has been cleared the user will begin typing, we need to check to see if the user has started typing and if they have then we need to display the suggestions box.

	// check if key has been pressed
	$(".suggestionsinput").keyup(function(event){
		if($(".suggestionsinput").val() != "")
		{
			// make suggestions visible
			$("#suggestions").css('visibility', 'visible');
			$("#suggestions").hide();
			$("#suggestions").fadeIn('slow');
			$(".searchterm").text($(".suggestionsinput").val());
			// $("#suggestions").load('http://URL.to.load');
 
		} else {
			// hide suggestions
			$("#suggestions").fadeOut('slow', function(){
				$("#suggestions").css('visibility', 'hidden');
			});
 
		}
	})

In this tutorial we are only making the drop down box visible, to load an actual list of suggestions uncomment $("#suggestions").load('http://URL.to.load'); then specify a URL where your script is that will load your suggestions and return it to the user.

The HTML File

		google.load("jquery", "1.3.2");

			// clear text from input
			$(".suggestionsinput").click(function(){
				if($(".suggestionsinput").val() == "Search")
				{
					$(".suggestionsinput").val("");
				}
			})
 
			// check if key has been pressed
			$(".suggestionsinput").keyup(function(event){
				if($(".suggestionsinput").val() != "")
				{
					// make suggestions visible
					$("#suggestions").css('visibility', 'visible');
					$("#suggestions").hide();
					$("#suggestions").fadeIn('slow');
					$(".searchterm").text($(".suggestionsinput").val());
					// $("#suggestions").load('http://URL.to.load');
 
				} else {
					// hide suggestions
					$("#suggestions").fadeOut('slow', function(){
						$("#suggestions").css('visibility', 'hidden');
					});
 
				}
			})

PHP gallery with no page reloads using jQuery

Wez Pyke — Wed, 23 Dec 2009 18:02:09 +0000

For this tutorial we will be using the ImgBrowz0r class for the backend of the gallery, we will then write a jQuery script so that we can browse through the gallery created by ImgBrowz0r without no page reloads and a nice effect between page requests so the user knows the page has changed. We will also be using the prettyPhoto plugin for jQuery to open up the actual images.

Getting ImgBrowz0r and prettyPhoto to work

The first thing I done was create a folder called jquery_gallery inside here is where all the files and folders are gonna be stored. I then created 4 folders inside jquery_gallery, the folders are called css, images, inc and js.

When you have downloaded the ImgBrowz0r class, copy the file into the inc folder.

Now inside the images folder create 2 folders cache and gallery. After you have unzipped prettyPhoto goto the images folder and inside the images folder copy the folder named prettyPhoto to our image folder. There should now be 3 folders inside our images folder cache, gallery and prettyPhoto.

Inside our css folder that we have created we will copy the css file from the prettyPhoto css folder named prettyPhoto.css.

The last thing to do for prettyPhoto is to copy the javascript file from the prettyPhoto js folder to our js folder.

So now we should have a file structure like so:
|css
|--prettyPhoto.css

|images
|--cache
|--gallery
|--prettyPhoto

|inc
|--imgbrowz0r.php

|js
|--jquery.prettyPhoto.js

We need to also create a css file for our imgBrowz0r class, create a css file inside our css folder and name it gallery.css. Copy the code into this file that is below:

strong { font-weight: bold }
 
	/* This is some example CSS. You can change this to your own liking. */
	.img-description, .imgbrowz0r-navigation, #imgbrowz0r { margin: 0 auto;width: 970px;text-align: left }
	.imgbrowz0r-navigation { padding: 1.5em 0 0.5em }
	.imgbrowz0r-navigation .img-statistics { margin-top: 1.5em }
 
	.img-description { margin: 1.5em auto 0 }
 
	#imgbrowz0r .img-row { padding: 0 1em }
	#imgbrowz0r .img-directory a:link,
	#imgbrowz0r .img-directory a:visited { font-family: Georgia, "Times New Roman", Times, serif;text-decoration: none }
 
	#imgbrowz0r .img-thumbnail a:link img,
	#imgbrowz0r .img-thumbnail a:visited img { border: 1px solid #000 }
	#imgbrowz0r .img-thumbnail a:hover img,
	#imgbrowz0r .img-thumbnail a:active img { border-color: #fff }
 
	#imgbrowz0r .img-directory a:link,
	#imgbrowz0r .img-directory a:visited { background-color: #000;border: 1px solid #000;font-size: 1.5em;color: #ccc }
	#imgbrowz0r .img-directory a:hover,
	#imgbrowz0r .img-directory a:active { border-color: #fff;color: #fff }
 
	#imgbrowz0r .img-directory span.img-dir-name,
	#imgbrowz0r .img-directory span.img-thumb-date { display: block }
	#imgbrowz0r .img-directory span.img-dir-name { font-weight: bold;font-size: 1.2em }
 
	#imgbrowz0r .img-thumbnail a,
	#imgbrowz0r .img-directory a { display: block;margin: 0 auto;width: 200px }
 
	#imgbrowz0r .img-thumbnail,
	#imgbrowz0r .img-directory { float: left;padding: 1.5em 0;width: 25%;text-align: center }
	#imgbrowz0r .img-column-1 { clear: left }
 
	#imgbrowz0r .img-directory a:link,
	#imgbrowz0r .img-directory a:visited { height: 160px;line-height: 150px;
					       background-repeat: no-repeat;background-position: 50% 50% }
 
	/* http://sonspring.com/journal/clearing-floats */
	html body div.clear,
	html body span.clear { background: none;border: 0;clear: both;display: block;float: none;font-size: 0;list-style: none;
			       margin: 0;padding: 0;overflow: hidden;visibility: hidden;width: 0;height: 0 }

Create a file called index.php in the root of our folder and copy in the basic html.




	
	TheTutorialBlog.com | Photo Gallery

Inside the div called content_main is where our the ImgBrowz0r class code will go.


require('inc/imgbrowz0r.php');
// These are all settings (set to default). The settings are not validated since you have to configure everything.
// There is a chance that ImgBrowz0r stops working if you enter the wrong values.
$config = array(
	// Directory settings. These are required. Without trailing slash. (required)
	'images_dir'               => 'images/gallery',
	'cache_dir'                => 'images/cache',
 
	// Url settings. These are required. Without trailing slash. (required)

	'images_url'               => 'http:///localhost:8888/tutorials/jquery_gallery/images/gallery',
	'cache_url'                => 'http:///localhost:8888/tutorials/jquery_gallery/images/cache',
 
	// Sorting settings (optional)
	'sort_by'                  => 3, // 1 = filename, 2 = extension (png, gif, etc.), 3 = inode change time of file
	'sort_order'               => false, // true = ascending, false = descending
 
	// Thumbnail settings (optional)
	'thumbs_per_page'          => 12, // Amount of thumbnails per page
	'max_thumb_row'            => 4, // Amount of thumbnails on a row
	'max_thumb_width'          => 200, // Maximum width of thumbnail
	'max_thumb_height'         => 200, // Maximum height of thumbnail
 
	// Time settings (optional)
	'time_format'              => 'F jS, Y', // Date formatting. Look at the PHP date() for help: http://nl3.php.net/manual/en/function.date.php
	'time_zone'                => 0, // Timezone. Example: 1
	'enable_dst'               => false, // Daylight saving time (DST). Set this to true to enable it.
 
	// Misc settings (optional)
	'ignore_port'              => false, // Ignore port in url. Set this to true to ignore the port.
	'dir_thumbs'               => true, // Show a thumbnail in a category box. Default is false.
	'random_thumbs'            => false, // Use random thumbnails for categories. Default is false.
	'read_thumb_limit'         => 0 // See README for information about this setting.
	);
 
// Start the class
$gallery = new imgbrowz0r($config);
 
 
// Prepare everything. This function must be called before you call other functions.
$gallery->init();
 
// Generate navigation and statistics
$gallery_breadcrumbs = $gallery->breadcrumbs();
$gallery_pagination = $gallery->pagination();
 
 
// Display navigation
echo '', "\n\t", $gallery_breadcrumbs, "\n\t", $gallery_pagination, "\n\t\n", '
', "\n\n";
 
// Display images and directories
echo $gallery->browse();
 
// Display navigation
echo '', "\n\t", $gallery_pagination, "\n\t", $gallery_breadcrumbs, "\n", '
', "\n\n";
?>

Fill in the information for the main_url, images_url and cache_url or it will not work.

In the imgBrowz0r.php file located in inc find line number 205 and add a rel called prettyPhoto:

'/', $this->cur_directory, $file[1], '" title="', $file[1], '" rel="prettyPhoto">, $this->config['cache_url'],

If we do not do this then the jQuery prettyPhoto plugin will not work.

Navigating through the gallery without page reloads

To do this we need to write our own jQuery code so that when a hyperlink inside the gallery div then we will do an ajax call that will then replace the content in the content_main div.

$('.img-directory a').click(function(){
	$.get($(this).attr("href"), function(data){
		$("#content_main").slideUp("slow", function(){
		$("#content_main").html(data)}), $("#content_main").slideDown()
	});
	return false;
})

So when a hyperlink inside the a div with the class called img-directory is clicked we will get the href from the hyperlink and retrieve that page using $.get(). We will then slide up the element until the content has loaded and then the elemnt will slide back down and contain the content we requested. We also return false so that the page does not reload.

We do the same for the breadcrumbs so we can navigate between them without the page refreshing also:

$('.img-breadcrumbs').click(function(){
	$.get($(this).attr("href"), function(data){
		$("#content_main").slideUp("slow", function(){
		$("#content_main").html(data)}), $("#content_main").slideDown()
	});
	return false;
});

The entire index.php page should look like so:




	
	TheTutorialBlog.com | Photo Gallery
	
	
	
	
	
 
	



require('inc/imgbrowz0r.php');
// These are all settings (set to default). The settings are not validated since you have to configure everything.

	'read_thumb_limit'         => 0 // See README for information about this setting.
	);
 
// Start the class
$gallery = new imgbrowz0r($config);
 
 
// Prepare everything. This function must be called before you call other functions.
$gallery->init();
 
// Generate navigation and statistics
$gallery_breadcrumbs = $gallery->breadcrumbs();
$gallery_pagination = $gallery->pagination();
 
 
?>
 


// Display navigation

Quick Tip: Resolving conflicting problems between jQuery and MooTools or any other Javascript library

Wez Pyke — Wed, 02 Dec 2009 23:51:10 +0000

Recently I wrote quite a huge chunk of jQuery for a website and it worked fine. A few days later I checked back to make sure that everything was working correctly after modifying a few things, but to my surprise none of the jQuery code worked. The problem was that I had added some Mootools code, the Mootools code worked fine but the jQuery code did not. I done some searching and found that the two libraries were conflicting and all it takes is 2 extra lines of code to prevent this from happening.

If you was to include jQuery and Mootools together this code below would not work:

$(document).ready(function(){
    alert("Hello World!");
});

But if we simply add jQuery(function($){ and }); then this code would work the way that we have intended.

The code would look like this:

jQuery(function($){
    $(document).ready(function(){
        alert("Hello World!");
    });
});
