Did you know you could add fields to the media uploader?
In my case, I was at a convention and a fellow reporter (welcome to my new weird life) muttered she wished it was easier to have just a photo ‘credit’ line when she uploaded media from networks. I asked what system she used to run her site and when she said WordPress, I gave her my biggest smile.
Image Filters
There are two things we need to filter here.
- Add our attribution field to the editor
- Save the attribution data
That’s it. WordPress handles the rest.
add_filter( 'attachment_fields_to_edit', 'halfelf_add_attachment_attribution', 10000, 2);
add_action( 'edit_attachment', 'halfelf_save_attachment_attribution' );
function halfelf_add_attachment_attribution( $form_fields, $post ) {
$field_value = get_post_meta( $post->ID, 'HALFELF_attribution', true );
$form_fields[ 'HALFELF_attribution' ] = array(
'value' => $field_value ? $field_value : '',
'label' => __( 'Attribution' ),
'helps' => __( 'Insert image attribution here (i.e. "NBCUniversal" etc)' )
);
return $form_fields;
}
function halfelf_save_attachment_attribution( $attachment_id ) {
if ( isset( $_REQUEST['attachments'][$attachment_id]['lwtv_attribution'] ) ) {
$attribution = $_REQUEST['attachments'][$attachment_id]['HALFELF_attribution'];
update_post_meta( $attachment_id, 'HALFELF_attribution', $attribution );
}
}
End Result?
It shows up a little lower down than I’d like (I’d prefer it to be up where the URL is) but it works:
Oh and yes, I emailed her the code as a stand-alone plugin. Her IT person was thrilled.
