I have the following functions:
function test($post_id){
do_action('test_action',$post_id);
echo $post_id;
}
add_action('test_action',function($post_id){
if ( $post_id == 2 ) //Stop test function execution
}
Using the function hooked to add_action, how to stop the execution of test() function without adding any code to test(). In the above example, if $post_id == 2 , the echo $post_id; code should not run in test().
You have both registered and called action hooks, did you know you could do the same with filters? This answer uses a filter to call a return; statement as the community suggested, to do an early return and stop executing the rest of test function body (echo in your case).
function test($post_id)
{
do_action('test_action', $post_id);
if ( apply_filters('wpse_405965_stop_execution', false) )
return;
echo $post_id;
}
add_action('test_action', function($post_id)
{
if ( $post_id == 2 ) // Stop test function execution
add_filter('wpse_405965_stop_execution', '__return_true');
});
The usual way to add an action hook is more like this:
// ... some other code
do_action( 'my_action', $post_id );
// ...elsewhere
add_action( 'my_action', 'wpse405965_function' );
/**
* Function hooked to my_action
*
* @param int $post_id The post ID.
*/
function wpse405965_function( $post_id ) {
if ( 2 !== $post_id ) {
echo $post_id;
}
}
The way you've wrapped the do_action() inside a function confuses me. It seems extraneous.
