As explained already, not a good idea :)
Also, if someone makes a copy of your form and excludes one of the fields,
then it won't be set in POST at all.
Keep an array of the fields you have in the form. I choose to set the field
as the key, and then for the value either 1 (required) or 0 (not required):
<?
// formPostArray.php
$formPostElements = array(
'first' => 1,
'last' => 0,
'email' => 1',
'age' => 0,
'sex' => 0
);
?>
Then include it where needed:
<?
include('formPostArray.php');
?>
Then use the array to check POST values are set, or better still, not empty:
<?
$error = 0;
foreach($formPostElements as $key => $val)
{
if($val)
{
if(empty($_POST[$key]) // could also be if(!isset($_POST[$key]))
{
$error = 3;
}
}
}
if($error)
{
header("Location: signup.php?error={$error}");
exit();
}
?>
In your case, street2 could be set to 0, and the rest set to 1.
You may also find that you can use the same array to write all your form
code as well, with a little work!!
