}

I want to make this field as a required field using php(it is required). what should i do for that

Answer 1

It’s not clear what you want do do, but if you’re using POST to send it to PHP then you can check if the value is empty like this

<?php 

if(empty($_POST['value_name']))
{
      echo 'value is required';
}
else
{
      // OK 
}
