Hi,
the easiest way to modify the fields in [adverts_add] is to use the drag and drop form editor in the Custom Fields extension.
If you are familiar with PHP programming you can also modify the form via adverts_form_load filter https://wpadverts.com/documentation/custom-fields/
For example to make the Location in [adverts_list] a dropdown you can paste the code below in your theme functions.php file
add_filter( "adverts_form_load", function( $form ) {
if( $form["name"] == "advert" ) {
return $form;
}
foreach( $form["field"] as $k => $field ) {
if( $field["name"] == "adverts_location" ) {
$form["field"][$k]["type"] = "adverts_field_select";
$form["field"][$k]["options"] = array(
array("value"=>"One", "text"=>"One"),
array("value"=>"Two", "text"=>"Two"),
);
}
}
return $form;
} );
Just replace the “One” and “Two” options with actual options you would like to use (and of course add an additional options).
P.S. It would be great if you could write your questions in English, thanks.
