for validating form field we can use php or javascript too.
both are easy but javascript is better than php.
You can use like below given example.
<script type=text/javascript>
function check()
{
if(document.getElementByID('f_name').value=='')
{
alert('Please enter Name');
return false;
}
}
</script>
<form action=post onSubmit='return check();'>
<input type=text id='f_name' name='f_name'/>
<input type='submit' value='submit' />
</form>
thank's
