I have little problem with Media Uploader in new WordPress 3.5. I created own plugin which is upload the picture. I’m using this code JS:

<script type="text/javascript">
    var file_frame;

    jQuery('.button-secondary').live('click', function( event ){

        event.preventDefault();

        if ( file_frame ) {
            file_frame.open();
            return;
        }

        file_frame = wp.media.frames.file_frame = wp.media(
            {
                title: 'Select File',
                button: {
                    text: jQuery( this ).data( 'uploader_button_text' )
                },
                multiple: false
            }
        );

        file_frame.on('select', function() {
            attachment = file_frame.state().get('selection').first().toJSON();
            jQuery('#IMGsrc').val(attachment.url);
        });

        file_frame.open();
    });
</script>

The code works fine, but unfortunately forms appears incomplete. When I select any picture doesn’t show me ‘Attachment Display Settings’ on right side. I don’t know why. I try add options to media:

displaySettings: true,
displayUserSettings: true

But it also doesn’t work.

Only Uploader

below a example code, works only on post edit page. If you will use also on other page, then include the function wp_enqueue_media(), see the next headline.

jQuery(document).ready(function($) {

  var _custom_media = true,
      _orig_send_attachment = wp.media.editor.send.attachment;

  $('.stag-metabox-table .button').click(function(e) {

    var send_attachment_bkp = wp.media.editor.send.attachment;
    var button = $(this);
    var id = button.attr('id').replace('_button', '');

    _custom_media = true;
    wp.media.editor.send.attachment = function(props, attachment) {

      if ( _custom_media ) {
        $("#"+id).val(attachment.url);
      } else {
        return _orig_send_attachment.apply( this, [props, attachment] );
      };

    }

    wp.media.editor.open(button);

    return false;
  });

  $('.add_media').on('click', function() {
    _custom_media = false;
  });

});

Short explanation of Media Manager

  1. At first include the relevant scripts, use the core function: wp_enqueue_media();
    The function set up all the relevant settings, localizes menu text, and loads in all the appropriate javascript files.

    You can add custom script via wp_enqueue_script().

    // Also adds a check to make sure `wp_enqueue_media` has only been called once.
    // @see: http://core.trac.wordpress.org/ticket/22843
    if ( ! did_action( 'wp_enqueue_media' ) )
        wp_enqueue_media();
    

    Add also a default script for custom header: wp_enqueue_script( 'custom-header' );
    This creates an image selection frame, and ties it to an interface element, for example a button or link. It then calls a url or our choice with the selected image id. This is the same script that is used when selecting theme custom header images.

  2. Add the button to media manager:

    <?php
    $modal_update_href = esc_url( add_query_arg( array(
        'page'     => 'my_media_manager',
        '_wpnonce' => wp_create_nonce( 'my_media_manager_options' ),
    ), admin_url( 'upload.php' ) ) );
    ?>
    
    <p>
    <a id="choose-from-library-link" href="#"
        data-update-link="<?php echo esc_attr( $modal_update_href ); ?>"
        data-choose="<?php esc_attr_e( 'Choose a Default Image' ); ?>"
        data-update="<?php esc_attr_e( 'Set as default image' ); ?>"><?php _e( 'Set default image' ); ?>
    </a> |
    </p>
    
  3. Define Action Function
    last, you need to add in some code for processing the image id that we will pass to the data-update-link url.

    // Add to the top of our data-update-link page
    if ( isset($_REQUEST['file']) ) { 
        check_admin_referer( 'my_media_manager_options' );
    
            // Process and save the image id
        $options = get_option( 'my_media_manager_options', TRUE );
        $options['default_image'] = absint( $_REQUEST['file'] );
        update_option( 'my_media_manager_options', $options );
    }
