WordPress: Media Uploader for Meta Boxes

so i’ve been running into a nagging issue with wordpress’ new instance of its media uploader (released in v3.5)

if i had a meta box with an image uploader, it would conflict with the standard “Add Media” button for the editor

previous code

uploader.js

jQuery(document).ready(function() {
var form_field;
jQuery('.button-upload').click(function() {
form_field = '#' + jQuery(this).next('input').attr('id');
tb_show('', 'media-upload.php?type=image&TB_iframe=true');
return false;
});

window.send_to_editor = function(html) {
imgurl = jQuery('img',html).attr('src');
if(!imgurl){
imgurl = jQuery(html).attr('src');
}
if (jQuery(form_field).length > 0) {
jQuery(form_field).val(imgurl);
}
tb_remove();
}
});

updated code

uploader.js

jQuery(document).ready(function($){
var _custom_media = true,
_orig_send_attachment = wp.media.editor.send.attachment;

$('#DIV_ID_GOES_HERE .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;
});
});

make sure to add this to your functions.php

function example_post_class_meta_box( $object, $box ) {
wp_register_script('my-uploader', get_bloginfo('template_directory') . '/js/uploader.js', array('jquery','media-upload','thickbox'));
wp_enqueue_script('my-uploader');
wp_enqueue_script('media-upload');
wp_enqueue_script('thickbox');
wp_enqueue_style('thickbox');

... blah blah blah ...

<p>
<input name="extra_featured_image_button" id="extra_featured_image_button" value="Choose Extra Featured Image" />
<input type="text" size="75" id="extra_featured_image" name="extra_featured_image" value="<?php echo get_post_meta($object->ID, '_extra_featured_image', true); ?>" />
</p>

in my research, i also found this, but i haven’t tried it out
