pre_do_shortcode_tag filter-hook . WP 4.7.0

Filters whether to call a shortcode callback.

Passing a truthy value to the filter will effectively short-circuit the shortcode generation process, returning that value instead.

Usage

add_filter( 'pre_do_shortcode_tag', 'filter_function_name_5481', 10, 4 );
function filter_function_name_5481( $return, $tag, $attr, $m ){
	// filter...

	return $return;
}
$return(true/false/string)
Short-circuit return value. Either false or the value to replace the shortcode with.
$tag(string)
Shortcode name.
$attr(array/string)
Shortcode attributes array or empty string.
$m(array)
Regular expression match array.
