$callback |

/**
* Add hook for shortcode tag.
*
* There can only be one hook for each shortcode. Which means that if another
* plugin has a similar shortcode, it will override yours or yours will override
* theirs depending on which order the plugins are included and/or ran.
*
* Simplest example of a shortcode tag using the API:
*
* // [footag foo="bar"]
* function footag_func( $atts ) {
* return "foo = {
* $atts[foo]
* }";
* }
* add_shortcode( 'footag', 'footag_func' );
*
* Example with nice attribute defaults:
*
* // [bartag foo="bar"]
* function bartag_func( $atts ) {
* $args = shortcode_atts( array(
* 'foo' => 'no foo',
* 'baz' => 'default baz',
* ), $atts );
*
* return "foo = {$args['foo']}";
* }
* add_shortcode( 'bartag', 'bartag_func' );
*
* Example with enclosed content:
*
* // [baztag]content[/baztag]
* function baztag_func( $atts, $content = '' ) {
* return "content = $content";
* }
* add_shortcode( 'baztag', 'baztag_func' );
*
* @since 2.5.0
*
* @global array $shortcode_tags
*
* @param string $tag Shortcode tag to be searched in post content.
* @param callable $func Hook to run when shortcode is found.
