[Plugin: WP-Table Reloaded] How can I use code to check if WP-Table is installed?

How about:
if ( class_exists( "CheckPlugin" ) )

Hi,

the function_exists() likely fails, because WP-Table Reloaded has its functions inside classes. So, you will need to use a different syntax.

It could also be possible that your plugin is run before WP-Table Reloaded has been included. When are you performing the function checks? You should at least wait until the action “plugins_loaded” is fired. Then, you could check for a function inside a class, or (which even works with function_exists(), you can check for the template tag function wp_table_reloaded_print_table().

The best way, in my opinion, would be to read the array of active plugins from WordPress (a global variable), that way you get a direct list of all activated plugins.

Hi,

thanks or the suggestion, Leon. Yes, you could of course simply check for the plugin’s class. However, the same applies: The point of time when you perform the check is important!

Thank you for the info, Tobias.

For now, I will go with Leon’s solution which worked beautifully.

Thanks to the both of you

Well Tobias did have a point.

You can also do the following:

add_action( 'plugins_loaded', 'check_plugin' );

function check_plugin(){
if ( class_exists( "CheckPlugin" ) ){
define( 'WP-Table-Active', 'true' );
}
}

and then check

if( defined( 'WP-Table-Active' ) ) {
//do actions
}
