bw_get_shortcode_function() – Return the function to invoke for the shortcode

You appear to be a bot. Output may be restricted

Description

Return the function to invoke for the shortcode

We need to cater for callbacks which are defined as object and function

Array 
( 
[0] => AudioShortcode Object 
( 
) 

[1] => audio_shortcode 
) 

Given that $callback is passed in and that is_callable should have already been called then we should always expect $callable_name to be set! But this doesn't mean that the $function should be callable.

Usage

$string = bw_get_shortcode_function( $shortcode, $callback );

Parameters

$shortcode

( string ) required – the shortcode to invoke

$callback

( mixed ) optional – default callback for the shortcode, if the 'all' or 'the_content' event is not defined for the shortcode.

Returns

string callable name for the shortcode function
