WordPress MU

I added a version comparison to my plugin in order to trigger an error on activation if the end user doesn't have PHP 5 or above installed. The problem is that even though it triggers the error and Wordpress informs me that it cannot activate the plugin due to a fatal error, it's still activating the plugin.

That, of course, is exactly the opposite of what I want happening.

The activation callback does a simple check,

if ( version_compare( phpversion(), '5.0', '<' ) )
	trigger_error('', E_USER_ERROR);

The code that error_scrape gets looks like the following,

if ( $_GET['action'] == 'error_scrape' )
    die( 'Message omitted for clarity' );

Yet the plugin still activates. Bad plugin, bad.

Have you tried using WP_Die() instead of trigger_error?

Yeah, which does work, the reason I liked the other method was the fact that it returned the user to the plugins page instead of simply halting their progress completely.

wp_die() does the trick though and until I can turn up a better method I'll stick with that, thanks tmoorewp!
