[Plugin: Facebook Like Box] [PATCH] Enqueue style and script only when used

Currently the files cardozafacebook.css and cardozafacebook.js are enqueued and loaded on every page load of the whole site, regardless of being used or not.

Both should be enqueued only when the plugin loads a Facebook box. Otherwise the plugin slows down every page (and makes a bigger percentage of pages too heavy to be used at all on old smartphones) even though it would be used only on a few pages.

The patch

1. In cardoza_facebook_like_box.php locate lines 12-13:

wp_enqueue_style('cfblbcss', plugin_dir_url(__FILE__).'/cardozafacebook.css');
		wp_enqueue_script('cfblbjs', plugin_dir_url(__FILE__).'/cardozafacebook.js', array('jquery'));

and replace them with

function cfblb_enqueue_if_needed() {
	if ( $GLOBALS['cfblb_enqueued_already'] != true ) {
		wp_enqueue_style('cfblbcss', plugin_dir_url(__FILE__).'/cardozafacebook.css');
		wp_enqueue_script('cfblbjs', plugin_dir_url(__FILE__).'/cardozafacebook.js', array('jquery'));
		$GLOBALS['cfblb_enqueued_already'] = true;
	}
}

2. Locate line 173

function widget_cardoza_fb_like($args){

and replace it with

function widget_cardoza_fb_like($args){
	cfblb_enqueue_if_needed();

3. Locate line 201

function cardoza_facebook_like_box_sc($atts){

and replace it with

function cardoza_facebook_like_box_sc($atts){
	cfblb_enqueue_if_needed();

4. Locate line 332

if($cfpl_enable == 'yes'){

and replace it with

if($cfpl_enable == 'yes'){
			cfblb_enqueue_if_needed();

5. And finally locate line 367

if (is_single()) {

and replace it with

if (is_single()) {
		cfblb_enqueue_if_needed();
