Embedding CBS Video

This spun out of someone who was _doing_it_wrong(). His plugin embed code reinvented all four wheels. First he was doing a reg4exp to implement shortcodes, then he was replicating oEmbeds that WordPress already has. I told him to first remove the ones that existed (so as not to cause conflicts) and then look up shortcodes.

But since the shortcodes he wanted to make were a little weird, I thought “Well, I know I would like to see the CBS Videos one, since I embed a lot of them…” So I took ten minutes to eat a cracker and re-write his code.

Here’s my code first.

// CBS Video Shortcode
function cbsvideo_func( $atts ) {
        extract( shortcode_atts( array(
                'id' => '00',
                'width' => '480',
                'height' => '270',
        ), $attr ) );

        return '<object width="'.$width.'" height="'.$height.'"><param name="movie" value="http://www.cbs.com/e/'.$id.'/cbs/1/" /></param><param name="allowFullScreen" value="true"></param><param name="allowScriptAccess" value="always"></param><embed width="'.$width.'" height="'.$height.'" src="http://www.cbs.com/e/'.$id.'/cbs/1/" allowFullScreen="true" allowScriptAccess="always" type="application/x-shockwave-flash"></embed></object>';
        }
add_shortcode( 'cbsvideo', 'cbsvideo_func' );

Then you use [cbsvideo id="9wFRf8KYoAXipnXgA8GKIm1VNaMgKjpE"] to embed it and have a beer. I put it in a file called sitewide-functions.php in my mu-plugins folder and walked away.

Here’s his code, as a reference.

define("CBS_WIDTH", 480); // default width
define("CBS_HEIGHT", 270); // default height
define("CBS_REGEXP", "/\[cbs ([[:print:]]+)\]/");
define("CBS_TARGET", "<object width=\"###WIDTH###\" height=\"###HEIGHT###\"><param name=\"movie\" value=\"http://www.cbs.com/e/###URL###/cbs/1/\" /></param><param name=\"allowFullScreen\" value=\"true\"></param><param name=\"allowScriptAccess\" value=\"always\"></param><embed width=\"###WIDTH###\" height=\"###HEIGHT###\" src=\"http://www.cbs.com/e/###URL###/cbs/1/\" allowFullScreen=\"true\" allowScriptAccess=\"always\" type=\"application/x-shockwave-flash\"></embed></object>");

function cbs_plugin_callback($match)
{
	$tag_parts = explode(" ", rtrim($match[0], "]"));
	$output = CBS_TARGET;
	$output = str_replace("###URL###", $tag_parts[1], $output);
	if (count($tag_parts) > 2) {
		if ($tag_parts[2] == 0) {
			$output = str_replace("###WIDTH###", CBS_WIDTH, $output);
		} else {
			$output = str_replace("###WIDTH###", $tag_parts[2], $output);
		}
		if ($tag_parts[3] == 0) {
			$output = str_replace("###HEIGHT###", CBS_HEIGHT, $output);
		} else {
			$output = str_replace("###HEIGHT###", $tag_parts[3], $output);
		}
	} else {
		$output = str_replace("###WIDTH###", CBS_WIDTH, $output);
		$output = str_replace("###HEIGHT###", CBS_HEIGHT, $output);	
	}
	return ($output);
}
function cbs_plugin($content)
{
	return (preg_replace_callback(CBS_REGEXP, 'cbs_plugin_callback', $content));
}

add_filter('the_content', 'cbs_plugin',1);
add_filter('the_content_rss', 'cbs_plugin');
add_filter('comment_text', 'cbs_plugin');

35 lines of code vs 11, and my 11 will run faster.
