[Plugin: Post Snippets] Add support for exisiting shortcodes

Great plugin.

I would love to see this implemented in the next release — it is such a small code change but it would help those how want to run their own shortcodes.

For example I have an email shortcode that is setup like this:

[email mailbox="name" url="domain" subject="subject" display_text="click me!"]

My own shortcode needs to run in order to obfuscate the input. So If I leave the Snippet Description empty it should run MY OWN shortcode rather than the Post Snippet Plugin.

So therefore this function should change as so:

/**
	* Create the functions for shortcodes dynamically and register them
	*
	*/
	function create_shortcodes() {
		$snippets = get_option($this->plugin_options);
		if (!empty($snippets)) {
			for ($i=0; $i < count($snippets); $i++) {
				if ($snippets[$i]['shortcode'] == true) {

           if( $snippets[$i]['snippet'] == '') continue; // no description so therefore don't do anything, grab the next shortcode and process.

             $vars = explode(",",$snippets[$i]['vars']);
             $vars_str = '';
             for ($j=0; $j < count($vars); $j++) {
               $vars_str = $vars_str . '"'.$vars[$j].'" => "",';

             }
					add_shortcode($snippets[$i]['title'], create_function('$atts',
								'$shortcode_symbols = array('.$vars_str.');
								extract(shortcode_atts($shortcode_symbols, $atts));

								$newArr = compact( array_keys($shortcode_symbols) );

								$snippet = "'. addslashes($snippets[$i]["snippet"]) .'";
								$snippet = str_replace("&", "&", $snippet);

								foreach ($newArr as $key => $val) {
									$snippet = str_replace("{".$key."}", $val, $snippet);
								}

								return stripslashes($snippet);') );
				}
			}
		}
	}
