I just installed a plugin that allows me to run scripts directly from WordPress pages and posts called exec_php. It worked great as long as I didn’t try to include or require php files.

Problem

For example, these snippets to include and require the existing file Log.php in a page or post

<?php include(”http://www.codeode.com/scripts/Log.php”); ?> or <?php require_once(”/scripts/Log.php”); ?>

would generate the following warnings:

Warning: Unknown(): URL file-access is disabled in the server configuration in /mnt/local/home/codeode/codeode.com/wp-content/plugins/exec-php/includes/runtime.php(42) : eval()’d code on line 4

Warning: Unknown(http://www.codeode.com/scripts/Log.php): failed to open stream: no suitable wrapper could be found in /mnt/local/home/codeode/codeode.com/wp-content/plugins/exec-php/includes/runtime.php(42) : eval()’d code on line 4

Warning: Unknown(http://www.codeode.com/scripts/Log.php): failed to open stream: no suitable wrapper could be found in /mnt/local/home/codeode/codeode.com/wp-content/plugins/exec-php/includes/runtime.php(42) : eval()’d code on line 4

Warning: (null)() [function.include]: Failed opening ‘http://www.codeode.com/scripts/Log.php’ for inclusion (include_path=’.:/usr/local/lib/php’) in /mnt/local/home/codeode/codeode.com/wp-content/plugins/exec-php/includes/runtime.php(42) : eval()’d code on line 4

Ok, as a WordPress rookie I am not completly sure why this is happening in the first place, anyone?

I started to search for solutions to the problem, but couldn’t find any good ones, only cumbersome that indicated me into changing the php.ini.

Solution

I ended up looking into WordPress code and found that they internally are using a variable called ABSPATH. This worked for me with WordPress 2.5.1:

<?php require_once(ABSPATH . “/scripts/Log.php”); ?>

I hope this post helps someone out there
