Remove index.php on CodeIgniter using .htacces

By default CodeIgniter framework url will includes index.php, it’s pretty easy to remove index.php from your url to work with CodeIgniter using .htaccess.

I assume that your web server already enable mod_rewrite module (mostly any web hosting already enable it). Create new file .htaccess in your CodeIgniter code root (same level with index.php) as like this.

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

Save it, and violaa… your CodeIgniter has pretty URL.

How to disable wordpress toolbar for all users

New wordpress engine has a feature called toolbar and its shown in the top of our blog page. What ridiculous is there’s no built-in function to disable this toolbar for being shown to all our users, which mean the users have to manually disable it in their profile page. Fortunately we can use this snippet to disable this toolbar.

Add this snippet to your theme functions.php file

function my_function_admin_bar(){
    return false;
}
add_filter( 'show_admin_bar' , 'my_function_admin_bar');

PHP Date Timezone error ( date_default_timezone_set )

I was experiencing an error regarding date() function on PHP 5 with error message like this :
Message: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Jakarta' for 'WIT/7.0/no DST' instead

For quick fix in PHP5, add this line 

date_default_timezone_set("Asia/Jakarta")

Access CPanel behind company proxy firewall

I was having problem accessing my web server from my company, my company network only open port 80 for internet access. So it would be impossible if someone trying to do to access CPanel behind this firewall.

But there’s a way for us to access CPanel via port 80 on our server, there’s no change at all both side our network or server. To access CPanel behind company firewall we can go to http://cpanel.domain.com, replace the domain.com with your own domain. For example http://cpanel.leoganda.net

By using this technique we are bypassing the port on our server, and accessing the port 80 over CPanel. So we gain access.

Solving Zend Framework error “An Error Has Occurred A project profile was not found”

Hi there, I had an error “An Error Has Occurred A project profile was not found” on Zend framework command line when I tried to generate an action for my project. I’m using Windows XP and for the web server I’m using XAMPP. The “An Error Has Occurred A project profile was not found” happened because we have wrong include path in our php.ini.

Open your php.ini and find the include_path line, insert your zend framework library path into the line before the PEAR path.

include_path = ".;E:\xampp\htdocs\ZendFramework\library;E:\xampp\php\PEAR"

Save the file and restart your Apache. Good luck 🙂
