Notice: Undefined index:address? whats this?

[Paul NIcolai Sunga]

here's the code i use..then the error appeared something like that..
Notice: Undefined index:address

<?php 
$a1 = $_POST['address'];
if($a1 = "")
{
echo "Empty Address Field.";
}
?>

and all other codes like this have the same error though it is not empty.

$surname = $_POST['surname'];
$sex = $_POST['sex'];
$firstname = $_POST['firstname'];
$cstatus = $_POST['cstatus'];
$middlename = $_POST['middlename'];
$weight = $_POST['weight'];
$age = $_POST['age'];
$blood = $_POST['blood'];
$pnumber = $_POST['pnumber'];
$year = $_POST['year'];
$month = $_POST['month'];
$day = $_POST['day'];
$email = $_POST['email'];
$address = $_POST['address'];
$category = $_POST['category'];
$team = $_POST['team'];
$browse = $_POST['Browse'];
$password = $_POST['password'];
$person = $_POST['person'];
$contactadd = $_POST['contactadd'];
$relationship = $_POST['relationship'];
$ecnumber = $_POST['ecnumber'];

what's wrong?

maybe you didn't post? print out $_POST to see, what it actually contains.

[Paul NIcolai Sunga]

thanks but it is stil not working.. i tried to print out but it produce the same error..

[Dormilich]

i tried to print out but it produce the same error..

how did you print out???

[Paul NIcolai Sunga]

<?php 

$a1 = $_POST['address'];
echo $a1;

?>

Do a print_r() on $_POST, is what Dormilich meant. print_r() will traverse an array and print it in readable format.

<?php

print_r($_POST);

?>

[Paul NIcolai Sunga]

this is what contains in my redirect page:

 
$Submit = $_POST['Submit'];

if($Submit == 'Submit')
{
//GETTING DATA IN FORM
$surname = $_POST['surname'];
$sex = $_POST['sex'];
$firstname = $_POST['firstname'];
$cstatus = $_POST['cstatus'];
$middlename = $_POST['middlename'];
$weight = $_POST['weight'];
$age = $_POST['age'];
$blood = $_POST['blood'];
$pnumber = $_POST['pnumber'];
$year = $_POST['year'];
$month = $_POST['month'];
$day = $_POST['day'];
$email = $_POST['email'];
$address = $_POST['address'];
$category = $_POST['category'];
$team = $_POST['team'];
$browse = $_POST['Browse'];
$password = $_POST['password'];
$person = $_POST['person'];
$contactadd = $_POST['contactadd'];
$relationship = $_POST['relationship'];
$ecnumber = $_POST['ecnumber'];
$others = $_POST['others'];

echo $firstname, $middlename, $surname, $address, $category, $year $month $day, $age, $pnumber, $email, $sex, $weight, $cstatus;
}
header('Location:registration.php');
exit();

then the error appears like this:
Notice: Undefined index: Submit in C:\wamp\www\red irect.php on line 3
this is the line 3: $Submit = $_POST['Submit'];
instead of printing the data in forms the error appear.

why? im so confused about it.

thanks

Try printing out $_REQUEST instead of $_POST, see what you get:
[code=php]
var_dump($_REQU EST);[/code]

Ignored again.

This error appears because of your PHP error reporting configuration settings. Normally , it appears when your variable is not properly set. There are two ways to fix this issue.

Check if $_POST['VAR_NAME_HERE'] is set before using it.
example:

if (!isset($_POST['VAR_NAME_HERE']))
{
//If not isset provide a dummy value here
$_POST['VAR_NAME_HERE'] = "";
}

or simply ignore the NOTICES from your error reporting settings.to do that modify your error_reporting settings on php.ini to

error_reporting = E_ALL & ~E_NOTICE

or else add this line to the top of your code

<?php error_reporting (E_ALL ^ E_NOTICE); ?>

[Paul NIcolai Sunga]

thanks a lot!!




is it common that E_NOTICE is always showing?

[Paul NIcolai Sunga]

i found the path to php.ini but the problem is i dont know how to configure it.

[ak1dnar]

find this line
error_reporting = E_ALL
and modify it with
error_reporting = E_ALL & ~E_NOTICE

save it and make sure to restart the web server too before test it.
