OOP and $this error message

[capbiker]

I am currently working on a php script within PHP5.

I keep on getting the following error message coming up:-

Fatal error: Using $this when not in object context in C:\xampp\htdocs\wp3_1\wordpress\wp-content\plugins\IPB_WP_bridge\wp_admin\admin_plugin.php on line 68

Here is the cut down version of the actual class and the actual function where the error message is being produced:-

class IPB_bridge_admin
{
	public function __construct()
	{
		require_once(ABSPATH . "wp-content/plugins/IPB_WP_bridge/WP_files/wpDebug.php");
		$this->wpDebug = new wpDebug;
	}

/**
* Will decided which settings page to load up and deal with.  If setting page as have had the form
* submitted then lets check and update the WP options database.  If not then lets just display the main form.
*
* @access      public
* @return      void
*/   

/**
 * This function will check to see if the required information i.e. Forums Directory as been completed and 
 * checks the path route.  If everything is ok then we will add the updated info to WP options database.
 * 
 * @access public
 * @return void
 */

public function IPB_bridge_update()
{
	$debug = $_POST['IPB_core_debug'];
	$level = $_POST['IPB_debug_level'];
	$request = "";

	$IPB_directory = $_POST['IPB_bridge_forum_directory'];

	if(trim($IPB_directory) != "")
	{	
		$IPB_directory = IPB_bridge_functions::forum_directory_check($IPB_directory, true, false);
	}

	if($debug == true)
	{
		if($level == 1)
		{
			$this->wpDebug->request_debug("BOTH");
		}
	}


	if($IPB_directory == "")
	{
		$IPB_bridge_forum_directory = $_POST['IPB_bridge_forum_directory'];
		$error = "There was a problem with the IPB forum directory, please recheck and try agian.";
		require_once(ABSPATH . "wp-content/plugins/IPB_WP_bridge/wp_admin/admin_bridge_config.php");
	}else
	{

		update_option('IPB_bridge_forum_directory', $IPB_directory);
		update_option('IPB_bridge_complete', true);
		require_once(ABSPATH . "wp-content/plugins/IPB_WP_bridge/wp_admin/admin_bridge_updated.php");

	}
}

The line where the error message is actual coming up from is:-

$this->wpDebug->request_debug("BOTH");

Has far as I can see, I am doing everything right. But it don't seem to like $this->wpDebug->request_debug("both");. I am actual stuck at knowing why this is happening.

So can anybody give me any advice on who to fix this?

Thanks.

Doesn't seem like you should be getting that error message based on the code you posted... can you post the unedited contents of the file in full?

Also, which version of PHP are you using?

[capbiker]

Here is the full coding:-

<?php

if ( ! defined( 'IPB_bridge' ) )
{
	print "<h1>Incorrect access</h1>You cannot access this file directly.";
	exit();
}


class IPB_bridge_admin
{
	public function __construct()
	{
		require_once(ABSPATH . "wp-content/plugins/IPB_WP_bridge/WP_files/wpDebug.php");
		$this->wpDebug = new wpDebug;
	}

/**
* Will decided which settings page to load up and deal with.  If setting page as have had the form
* submitted then lets check and update the WP options database.  If not then lets just display the main form.
*
* @access      public

I do know what you mean, it gotten my stump why it is working correctly for.

Are you sure that's an exact copy-paste of the file's contents? The error message indicates a $this on line 68, yet the 68th line of your code snippet is a blank line.

Also, you never answered my second question above - which version of PHP are you using?

[capbiker]

I just took out a few lines at the start of it.

I am using PHP 5.2.9 on a localhost.

[bradgrafelman]

While I don't have a 5.2.9 install handy to test with, I wouldn't think that it would be much different than 5.3.2, and in the latter version the script produced the '<h1>Incorrect access</h1>You cannot access this file directly.' output and no PHP errors.

Are you sure you're looking at the right file? I'm at a loss as to what to suggest next...

[capbiker]

Yes that is the right file.

I will have to work around the problem and only use static calls instead.

[NogDog]

Are you trying to call the method statically somewhere in the code that uses this class?
