Advertisement categorie as mandatory field + limit category chosing to one

Hi,
you can do both by adding the code below to your theme functions.php file

add_filter( "adverts_form_load", "customize_adverts_add" );
function customize_adverts_add( $form ) {
  if( $form['name'] != "advert" ) {
    return $form;
  }
  foreach( $form["field"] as $key => $field ) {
    if( $field["name"] == "advert_category" ) {
        $form["field"][$key]["max_choices"] = 1;
        $form["field"][$key]["validator"] = array( "name"=> "is_required" );
    }
  }
  return $form;
}

Thank you!

Good morning, GREG.

That did not work for me.

Give an error in the plugin functions.php line 513 wpadverts.

This functionality interests me a lot.

Welcome to work again.

Hi, please paste here the error you see after adding the code?

Good afternoon
Error returning by putting in the theme’s function.php file.
Warning: Illegal string offset ‘name’ in C: \ xampp \ htdocs \ otherroutes \ wp-content \ plugins \ wpadverts \ includes \ functions.php on line 517

Remembering that I am using custom fields

Try changing the line

$form["field"][$key]["validator"] = array( "name"=> "is_required" );

to

$form["field"][$key]["validator"][] = array( "name"=> "is_required" );
