3 Views

I am trying to trigger an action in functions.php with the do_action() function, but I appear to need an attribute.

The following

do_action( 'really_simple_share button="facebook_like"');

does not work…

Can you tell me the proper way to make it work (I have tried many other things that did not work either).

  1. The correct way is to pass first argument as a unique string which acts as an identifier for the action & any additional arguments after that

    do_action('unique_action_tag', $parameter1, $parameter2,,,, & so on);

    To attach functions to this action you’ll do

    // 10 is the priority, higher means executed first
// 2 is number of arguments the function can accept
add_action('unique_action_tag', 'my_custom_function', 10, 2)
function my_custom_function($param1, $param2) {
    // do something
}
