There is no function provided by php that does what you are asking. So the answer is correct, you're just wanting somebody to make the code for you instead of doing it yourself. Maybe try learning a bit more basic php so you don't have to wait all day to solve simple dilemmas.

 

if( empty( trim($_POST['name']) ) )
{
    echo 'Text field _name_ cannot be empty.';
}
