Hello @pauldewin,
I’m glad that the plugin was useful to you.
You can try this snippet:
(adding attachment will be allowed only for category with ID 56)
function custom_dco_ca_disable_attachment_field() {
$url = "//{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";
$post_id = url_to_postid( $url );
$cats = wp_get_post_categories( $post_id, array( 'fields' => 'ids' ) );
$allow_cat_id = 56;
if ( in_array( $allow_cat_id, $cats ) ) {
return false;
}
return true;
}
add_filter( 'dco_ca_disable_attachment_field', 'custom_dco_ca_disable_attachment_field' );
I just used this code and it worked seamlessly. Thanks so much, Denis!
Well, I spoke too soon. While this code does restrict the upload option to a particular category, it also breaks the attachment upload functionality. Now whenever I upload an image, it posts the comment, but it doesn’t upload/attach the image. Any suggestions?
Hmm, indeed, the upload stopped working after applying the code. At the moment, I don’t know how to fix it. I’ll try to come back to this later.
For a quick fix, you can try this snippet.
function disable_upload_field( $markup ) {
if( ! in_category( 56 ) ) {
return '';
}
return $markup;
}
add_filter( 'dco_ca_form_element_label', 'disable_upload_field' );
add_filter( 'dco_ca_form_element_input', 'disable_upload_field' );
It will not disable upload altogether, but will hide the upload field in all categories except the specified one.
Just tried that code and my site crashed. 🙁 I’m back online now, but unfortunately I’m not savvy enough to troubleshoot why it went down.
Any ideas or suggestions on why that code snippet above would cause a critical error?
