Chronoforms 8.0.9 - regex

Question

Hello...how can i stop the following characters for textareahrefwwwhttpshttp.xyz

use PHP validation for this (Valid Function) behavior:

if(str_contains($value, "href")){
return "your message should not contain href";
}
return true;

this will not stop the form to be submitted by the browser but users will not be able to send the form, it will show an error message

Block specific characters in a ChronoForms textarea.
