We always use this nifty “Insert into Post” button when uploading image in any types of field, including uploading a image for some meta field or anything else. Then we attach a JavaScript listener on window.send_to_editor and insert the attachment/image URL to the input field.
Today I needed a way to get the attachment ID instead of the URL. So I added an HTML5 data attribute on the link and grabbed the value.

1 2 3 4 5 6 7 8 9 10 11 12 |
/** * Add an HTML5 data attribute to the link * * @param string $html * @param int $id * @return string */ function wedevs_send_to_editor( $html, $id ) { return str_replace( '<a href', '<a data-id="' . $id . '" href', $html ); } add_filter( 'image_send_to_editor', 'wedevs_send_to_editor', 10, 2 ); |
So now you’ve the HTML5 data attribute and it’s super easy to grab the value.

window.send_to_editor = function(html) { var attachment_id = $(html).data('id'); tb_remove(); }; |
Easy peasy 🙂
