Insert attachment ID in custom field from media uploader

1 Views

This is what I want to do:

  1. In the media uploader, add a link “Use this attachment ID as custom field”.
  2. Add the attachment ID in a custom fields meta box.

I’ve searched for hours for a plugin that does this but found nothing. Code examples, plugins, hints. Anything might be helpful.

  2. When you upload attachments to a post/page they become child elements of that post/page.

    What you can do is provide a drop down in your custom field to list all uploaded files to the uploader for the current post/page. This is the code I used to show a list of files so the user could select which one was a floor plan image:

          <select name="chb_homes_for_sale_specifics_floor_plan" style="width:100%;">
        <option value="" <?php selected($custom["chb_homes_for_sale_specifics_floor_plan"][0], ""); ?>>No Floor Plan</option>
        <?php
        $args = array(
            'numberposts'     => -1,
            'orderby'         => 'menu_order',
            'order'           => 'ASC',
            'post_type'       => 'attachment',
            'post_parent'     => $post->ID,
            'post_mime_type' => 'image'
        );
        $image = get_posts($args);
        if($image) {
            foreach($image as $key => $data) : ?>

                <option value="<?php echo $data->ID; ?>" <?php selected($custom["chb_homes_for_sale_specifics_floor_plan"][0], $data->ID); ?>><?php echo basename ( get_attached_file( $data->ID ) ); ?></option>

            <?php endforeach;
        }
        ?>
      </select>
