Currently it is not possible to add such validator in WPAdverts i am afraid.
So is it impossible to make a validator code that will do just that in the WPAdverts?
If i cannot make a code is there anyway i can have a parenthesis saying (max posting price cannot exceed $20) next to the Price feature?
It is possible to write such validator, but this is right now rather complex, and beyond the free support offered here, sorry.
To add a note below the price field you can add this code to your theme functions.php file
add_filter( "adverts_form_load", "customize_price_note" );
function customize_price_note( $form ) {
if( $form['name'] != "advert" ) {
return $form;
}
foreach( $form["field"] as $key => $field ) {
if( $field["name"] == "adverts_price" ) {
$form["field"][$key]["placeholder"] = "max posting price cannot exceed $20";
}
}
return $form;
}
That is awesome Greg, thank you so much for your help and time I really appreciate it!
I understand that the validator I was asking for initially is complex and beyond the free support, however when my website is up and gains more traffic I will be willing to pay you for something like that if you are interested.
Thanks again for all your help!
