validate name

[bal bal]

hi

here is my code for name field which is a text box. it is working if I put any digit or if the field is empty but when I put the symbols like '%$%^&*!' it still takes the value not showing any error.

 

if ((is_numeric($name))||(empty($name)))

        {

        echo 'please enter your name<br>';

        return;

        }

 

can anyone please help me...

 

thanks

quick google search turned up this quick regex you can use

 

<?php
if (ereg('[^A-Za-z0-9]', $text)) {
  echo "This contains characters other than letters and numbers";
}
else {
  echo "This contains only letters and numbers";    
}
