I have been using a custom code to upload images to Wordpress using custom metaboxes. Here is the code:

<script type="text/javascript">

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

        var formfield;

        $('.upload_button').click(function() {
            formfield = $(this).prev('.upload_image'); // .attr('name');
            tb_show('', 'media-upload.php?type=image&TB_iframe=true');
            return false;

        // user inserts file into post. only run custom if user started process using the above process
        // window.send_to_editor(html) is how wp would normally handle the received data

        window.original_send_to_editor = window.send_to_editor;
        window.send_to_editor = function(html){

            if (formfield) {
                fileurl = jQuery('img',html).attr('src');

                formfield = '';

            } else {



My actual problem is that I have to upload now a PDF. I have try to use the .urlfield input in the media uploader with keeps the URL of the uploaded file.

I have changed fileurl = jQuery('img',html).attr('src'); to fileurl = jQuery('.urlfield',html).val(); but it does not work.

What can I do please?

An alternative tip I would like to know is how can I change the "Insert button" value text to something like "Use this file".

Thanks in advance.
