Archive for the ‘Codeigniter’ Category

As we know that Codeigniter provides a very good feature that can auto encrypt the session for the php application.


So for the higher security, we can put  random words here to instead of ‘session’ as the above pic showed. There, I will refer from other people’s tutorial, suggest a website that can generate the random key as showed below.

Here, you can copy the keys directly and put to the config at Codeigniter.

To remove the ‘index.php’, can config by the follwing steps:

1. create a new file in the root folder, and named -> ‘.htaccess’.

2. copy the following code to the ‘.htaccess’ file.

<IfModule mod_rewrite.c>
#http://codeigniter.com/wiki/mod_rewrite
RewriteEngine On
RewriteBase /

#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#’system’ can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#When your application folder isn’t in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename ‘application’ to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn’t true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
# If we don’t have mod_rewrite installed, all 404’s
# can be sent to index.php, and everything works as normal.
# Submitted by: ElliotHaughin

ErrorDocument 404 /index.php
</IfModule>

3. change the ‘RewriteBase /’ if you put the codeigniter in other foler such as ‘/ci/’.
Then need to change as ‘RewriteBase /ci/’. (the sensitive of upper and lower case)

4. change the ‘application/config/config.php’
-> $config[‘index_page’] = ‘index.php’;
-> $config[‘index_page’] = ”;

5. open the Apache ‘httpd.conf’
-> find the line ‘#LoadModule rewrite_module modules/mod_rewrite.so’
-> delete the ‘#’ in front and save, start / restart Apache.
