embed the_content

Question

So I’ve never really found out why oembed urls added via apply_filters('the_content', $output), are not processed while embed shortcodes are. Im still hopeful someone might shed some light on that.

I really wanted to use Alex King’s post type formats UI which is why I didn’t follow David’s example.

I ended up detecting the input using strpos and substr because that seemed the most direct. If anyone knows a better way of doing it, or sees some flaw in my approach please chime in!

<?  // deal with embeds from the _format_video_embed meta meta feild

// allow us to strpos an array

function strpos_arr($haystack, $needle) { 
    if(!is_array($needle)) $needle = array($needle); 
    foreach($needle as $what) { 
        if(($pos = strpos($haystack, $what))!==false) return $pos; 
    } 
    return false; 
}       
$embedCheck = array("<embed", "<video", "<ifram");// only checking against the first 6

$mykey_values = get_post_custom_values('_format_video_embed');
$content_oembed = '';
     foreach ( $mykey_values as $key => $value ) {    
    if (!empty($value)) {
        $firstCar = substr($value, 0, 6); // get the first 6 char 

        if ( strpos($firstCar, "http:/" ) !== false || strpos($firstCar, "https:" ) !== false ){  
             // if its a http(s), send it to wp_oembed to see if the link is oembed enabled, and if not - output a link
            (wp_oembed_get($value) !==false ? $output="<div class="oembed" style="width:100%; overflow:hidden;">" . wp_oembed_get($value) . '</div>' : $output="<a href="" . $value . '" target="_blank"><button class="btn"><i class="i icon-film"></i>Video link: ' . $value . '</button></a><hr>' );
        }       
        else if (strpos_arr($firstCar, $embedCheck ) !== false ){ //if it comes back as an embed, video, or iframe return the full string to the content                 
            //$output="<div class="oembed" style="max-width="500px"><p>something funny</p>" . $value . '</div>'; // we're wrapping it so we can style it with fitvid
            $content_oembed = $value;                   
        }
        else if( current_user_can('publish_posts') ){// a little error for the editor
                $content_oembed = "<div class="alert alert-error"><strong>Whoops! That embed link or code has problems:</strong></br>";
                $content_oembed .= "URLS should begin with http:// or https:// <br/>";
                $content_oembed .= "Embed code should be wrapped in either &lt;embed&gt;&lt;/embed&gt; &lt;video&gt;&lt;/video&gt; or &lt;iframe&gt;&lt;/iframe&gt; elements.";
                $content_oembed .= "<p class="well">" . $value . "</p></div>";
            }
        }                       
};
//echo apply_filters('the_content', $content_oembed);   
?>
