Wordpress media upload extra field

How do I make another field available in the wordpress media panel?

Currently you have all your necesary fields, although I need to add one extra to capture some extra details.

I am using a flash playe开发者_开发百科r that looks for a set of fields, ideally I would like to a field called video_url

Any ideas?

I'm not sure how to add an extra field inside the media panel... but you could use Magic Field to create a media uploader and an extra field which will contain your extra details... Learn more about Magic Field Plugin here : http://wordpress.org/extend/plugins/magic-fields/

Came up with this solution.

function rt_image_attachment_fields_to_edit($form_fields, $post) {
    // $form_fields is a an array of fields to include in the attachment form
    // $post is nothing but attachment record in the database
    //     $post->post_type == 'attachment'
    // attachments are considered as posts in WordPress. So value of post_type in wp_posts table will be attachment
    // now add our custom field to the $form_fields array
    // input type="text" name/id="attachments[$attachment->ID][custom1]"
    $form_fields["rt-image-link"] = array(
        "label" => __("Video URL"),
        "input" => "text", // this is default if "input" is omitted
        "value" => get_post_meta($post->ID, "_rt-image-link", true),
            "helps" => __(""),
    );

    $form_fields["rt-video-link"] = array(

    );
    return $form_fields;
}
// now attach our function to the hook
add_filter("attachment_fields_to_edit", "rt_image_attachment_fields_to_edit", null, 2);

    if( isset($attachment['rt-image-link']) ){

        update_post_meta($post['ID'], '_rt-image-link', $attachment['rt-image-link']);
    }
