How to use "if_fuction_exists" to prevent fatal errors

[Caroline]

Because we’ve integrated the Events Calendar and WooTickets into our WordPress theme, when we turn off them off, it causes our entire site to stop working.

How can we use “if_fuction_exists” in our functions.php to check if these plugins are present, and if not, display a message in the admin instead of crashing the entire website?

Thanks in advance.

Hi,

Thanks for using our plugins I can help out here.

You can us if class exists to wrap coding for the Events Calendar or WooCommerce tickets and it will only run then if the plugin is active.

This code checks for The Events Calendar and Pro to be active:

if ( class_exists( 'Tribe__Events__Main' ) && class_exists( 'Tribe__Events__Pro__Main' ) ) {
//coding here
}

This code checks for WooCommerce Tickets to be active:

if ( class_exists( 'Tribe__Events__Tickets__Woo__Main' ) ) {
//coding here
}

Let me know if that works for you.

Thanks
