reject empty form fields

[sudeepk]

I have 17 form fields. I use $_post to get the variables. Please let me know how to stop the form being submitted if any form field is left blank. I tried but couldn't solve. Please help me.

 

$name = $_POST["name"];
$email = $_POST["email"];
$ans1 = $_POST["ans1"];
$ans2 = $_POST["ans2"];
$ans3 = $_POST["ans3"];
$ans4 = $_POST["ans4"];
$ans5 = $_POST["ans5"];
$ans6 = $_POST["ans6"];
$ans7 = $_POST["ans7"];
$ans8 = $_POST["ans8"];
$ans9 = $_POST["ans9"];
$ans10 = $_POST["ans10"];
$ans11 = $_POST["ans11"];
$ans12 = $_POST["ans12"];
$ans13 = $_POST["ans13"];
$ans14 = $_POST["ans14"];
$ans15 = $_POST["ans15"];
$ans16 = $_POST["ans16"];

 

These are the variables.

if(!empty($name) && !empty($email)...) {
//Submit form
} else {
//Produce error, redisplay form etc.
}

if its empty when submitted it wont be declared $_POST['empty_field'] that is.

 

use isset($_POST['whatever']) instead

 

true on existing

 

if you dont have strict PHP on - then dont worrie

i cannot blame you for your bad english, but

there are 18 filelds mentioned...

 

but that has nothing to do with the problem which is unclear because of the 3 or 4 obvious langage errors on 1 sentence...

I understand your pain. Thanks for your concern regarding my language. I appreciate your effort in finding the mistakes(regardless of how noticeable they were). But yeah, you should work on your perception part. See! Other people could understand it even though it had mistakes. Being smart is not everything.

 

@Muffins

I think i tried the same. It dint seem to work.

 

@HavokDelta6

I will try to put that to use. Thanks.

<irony>Yeah, jskywalker you don't have any people skills. You obviously need to work on that.</irony>

Yeah, i was doing it wrong placing it above the declared variables. It definitely worked. Thanks.
