Fügen Sie eine Metabox mit Media Uploader in einem benutzerdefinierten Beitragstyp hinzu

Ich muss eine "Medien-Uploader-Metabox" erstellen und meinem benutzerdefinierten Beitragstyp hinzufügen. Ich habe bereits normale Metaboxes erstellt, die Funktion zum Hinzufügen zum benutzerdefinierten Post-Typ und die Funktion zum Speichern. Ich muss nur den Media-Uploader von WordPress verwenden, kann aber nicht herausfinden, wie das geht. Danach würde ich so etwas wie "Add more image" einfügen, das der Seite mehr Metaboxen hinzufügt.

Sowas in der Art: enter image description here

Ich arbeite an etwas ähnlichem. Dies ist eine Podcast-Upload-Meta-Box. Gibt die URL zur Datei zurück. Folgendes habe ich bisher:

//Add Metabox
add_action('add_meta_boxes', 'add_upload_file_metaboxes');

function add_upload_file_metaboxes() {
    add_meta_box('swp_file_upload', 'File Upload', 'swp_file_upload', 'podcasts', 'normal', 'default');
}


function swp_file_upload() {
    global $post;
    // Noncename needed to verify where the data originated
    echo '<input type="hidden" name="podcastmeta_noncename" id="podcastmeta_noncename" value="'.
    wp_create_nonce(plugin_basename(__FILE__)).
    '" />';
    global $wpdb;
    $strFile = get_post_meta($post -> ID, $key = 'podcast_file', true);
    $media_file = get_post_meta($post -> ID, $key = '_wp_attached_file', true);
    if (!empty($media_file)) {
        $strFile = $media_file;
    } ?>


    <script type = "text/javascript">

        // Uploading files
        var file_frame;
    jQuery('#upload_image_button').live('click', function(podcast) {

        podcast.preventDefault();

        // If the media frame already exists, reopen it.
        if (file_frame) {
            file_frame.open();
            return;
        }

        // Create the media frame.
        file_frame = wp.media.frames.file_frame = wp.media({
            title: jQuery(this).data('uploader_title'),
            button: {
                text: jQuery(this).data('uploader_button_text'),
            },
            multiple: false // Set to true to allow multiple files to be selected
        });

        // When a file is selected, run a callback.
        file_frame.on('select', function(){
            // We set multiple to false so only get one image from the uploader
            attachment = file_frame.state().get('selection').first().toJSON();

            // here are some of the variables you could use for the attachment;
            //var all = JSON.stringify( attachment );      
            //var id = attachment.id;
            //var title = attachment.title;
            //var filename = attachment.filename;
            var url = attachment.url;
            //var link = attachment.link;
            //var alt = attachment.alt;
            //var author = attachment.author;
            //var description = attachment.description;
            //var caption = attachment.caption;
            //var name = attachment.name;
            //var status = attachment.status;
            //var uploadedTo = attachment.uploadedTo;
            //var date = attachment.date;
            //var modified = attachment.modified;
            //var type = attachment.type;
            //var subtype = attachment.subtype;
            //var icon = attachment.icon;
            //var dateFormatted = attachment.dateFormatted;
            //var editLink = attachment.editLink;
            //var fileLength = attachment.fileLength;

            var field = document.getElementById("podcast_file");

            field.value = url; //set which variable you want the field to have
        });

        // Finally, open the modal
        file_frame.open();
    });

    </script>
