shortcode_parse_atts() │ WP 2.5.0

Retrieve all attributes from the shortcodes tag.

The attributes list has the attribute name as the key and the value of the attribute as the value in the key/value pair. This allows for easier retrieval of the attributes, since all attributes have to be known.

#2 Cut and break down the shortcode parameters

An example of how you can cut a shortcode parameter string and parse it into separate key=value

$str = <<<'STR'
	Content
	[five_element name="big badaboom" ident="multipassport" foo='bar']
	More Content
STR;

// for this check, the shortcode must be registered in WP, see: add_shortcode()
if( ! has_shortcode( $str, 'five_element' ) ){
	echo 'Shortcode not found';
}

preg_match( '~\[five_element(.+)\]~s', $str, $mm );

$res = shortcode_parse_atts( $mm[1] );

print_r( $res );

/*
Array
(
	[name]  => big badaboom
	[ident] => multipassport
	[foo]   => bar
)
*/
