thanks alok... Can you tell me if i set action="inq_mail.php" then what we need to do... where inq_mail.php contain code which send mail to given email address. – user3060235 Dec 13 '13 at 08:32
nothing you need to do just put action="inq_mail.php" in form and use $_POST['name'] to get all values – user7789076 Dec 13 '13 at 08:35
but it move to inq_mail.php without any warn message field is empty?? – user3060235 Dec 13 '13 at 08:42
it looks ok to me...What issue you are facing? – user7789076 Dec 13 '13 at 10:30
I want if form field empty then it show me message on form (inquery.php) not move to inq_mail.php – user3060235 Dec 13 '13 at 11:13
Instead of doing validation in php i will recomend javascript check this:http://www.w3schools.com/js/js_form_validation.asp – user7789076 Dec 13 '13 at 13:05
i will recomend client side – user7789076 Dec 13 '13 at 13:13

You can do it with HTML5, adding required attribute to your fields as:

<!DOCTYPE html>
<html>
<body>
<form action="http://google.com">
 <input type="text" name="q" required/>
 <input type="submit" />
</form>
</body>
</html>

enter image description here

Remember that PHP process data in server side, if you need a more complex validation in client side, you should use JavaScript (JQuery).

Validation on the client-side is for it to be user-friendly. You **MUST** validate on the server-side no matter what. – Ali Dec 13 '13 at 08:32

@user3060235 - A couple of expansion points ...

Expanding on alok's answer - your submit button did not have a name attribute on it. This is critical to insure the form field gets bound to the PHP $_POST variable.
Expanding on Ignacio's answer - The HTML5 attribute is very useful but this is only done on the client side. While this is nice from a user experience perspective, you still need to validate form parameters on the server-side. JavaScript: client-side vs. server-side validation
On form submission and completion of previous suggestions, the exit() statement will prevent the user from seeing the form again to resubmit their input. You might actually want this depending on the client ask, but if you don't want that you need to remove the exit statement.

thanks user2910265.. but i want solve my actually problem. i appriciate Lgnacio which tell me ans with update ver of html5. — user3060235, Dec 13 '13 at 08:45
