Codeigniter
Please install Codeigniter and work through the first part of the tutorial:
Installing Codeigniter
You can install either using Composer, or manually:
Either way, you will then need to set the correct file permissions via Putty, as follow:
chmod 755 ci4-composer/ -R chmod 777 ci4-composer/writable/ -R
You will also need to update a couple of config files (located in app/Config).
In App.php, populate the base URL with the URL to the folder where you installed CodeIgniter, for example for mine I have put:
public $baseURL = 'https://mi-linux.wlv.ac.uk/~in9352/ci4/public/';
- in9352 should be replaced with your student number
- ci4 is the name of the folder in which you installed the framework
- public has to be there.
You also need to populate your MySQL connection details in the Database.php file:
'username' => '',
'password' => '',
'database' => '',
How to include external files (images, css files, js files) on my pages
First make sure your base URL is populated in your config.php file, so for example for me:
$config['base_url']='http://mi-linux.wlv.ac.uk/~in9352/codeigniter3/';
Then upload your files in your "codeigniter" folder, or in suitable sub-folders (codeigniter/images, codeigniter/css and codeigniter/js). Do NOT upload the files into your codeigniter/application folder or any of its sub folders.
In the example below I have uploaded an image and a CSS file at the following locations:
- codeigniter3/css/style.css
- codeigniter3/funnycat.jpg
Finally use the "Base URL" helper in your view:
<?php $this->load->helper('url');?>
<html>
<head>
<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
<link rel="stylesheet" type="text/css" href="<?=base_url("css/style.css")?>">
</head>
<body>
<h1>CodeIgniter Tutorial</h1>
<p>
<img src="<?=base_url("funnycat.jpg")?>">
</p>
Hiding "index.php" using URL rewriting
Create a .htaccess file in your CodeIgniter root folder, and paste the following rules inside it:
RewriteEngine on
RewriteBase /~in9352/codeigniter3/
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_URI} !\.(css|gif|ico|jpg|js|png|swf|txt)$
RewriteRule ^(.*)$ index.php/$1 [L]
Note: replace "in9352" by your student number.
Working example here: http://mi-linux.wlv.ac.uk/~in9352/codeigniter3/news/index
