So I know in Wordpress there are several built-in functions for checking what page the user is currently viewing, but I needed to be able to check what page when not using Wordpress. After some searching I found this really simple PHP snippet for doing just that. Add this code somewhere in your PHP file so you can perform an action depending on the current URL:

<?php
 
$uri = $_SERVER['REQUEST_URI'];
if ($uri == "/") {
      echo "You're on the homepage";
} else {
     echo "You're on an internal page";
}
 
?>

Joomla CHMOD Trick when Installing Extensions

Friday, July 9th, 2010 Posted in Hacks


Are you getting Joomla an error like it can’t create a new directory when you try to install an extension? I can’t remember where I found it but this little PHP script will allow you to change the permissions for all of the  necessary folders in one shot when run in a browser. It will save you much time and headache trying to do it one by one. Thanks to the original creator! This is how to use it:


  1. Copy and paste the text into a new text file. Save it as “chmod.php”
  2. Upload the file to the root of your site and go to the following URL in your browser: http://www.yoursite.com/chmod.php?chmod=0777
  3. Upon hitting return, you should get a screen indicating success listing all of the directories of which it has changed the permissions. If something went wrong then you will get a different screen indicating it failed. Usually this is because the base path is wrong in chmod.php. ( The base path is usually something like “httpdocs/” )
  4. Install your extensions
  5. Once you’ve installed your extensions, go to: http://www.yoursite.com/chmod.php?chmod=0755 to change the permissions back to 755 so your files aren’t vulnerable.
