I'm trying to create a form system where 3 pages will ask you your name, age, address, and all the missing input will be listed on the confirmation page after the 3rd page.
Please someone help me... been trying for a couple of hours and I'm new to PHP.
----- This is the script for the confirmation page----------------
<?php
// unset the formStarted session variable
unset($_SESSION['formStarted']);
// go through the elements in the $_SESSION
foreach ($_SESSION as $key => $value) {
// skip the missing element
if ($key == "missing"){continue;}
// skip the submit buttons
// use identity operator with strpos to prevent false negatives
if (strpos($key, 'Submit') === 0) {
continue;
}
echo "<li>$key: $value</li>";
}
// clear the $_SESSION array and destroy session
$_SESSION = array();
session_destroy();
?>
</ul>
<?php
if(isset($_SESSION['missing'])){
$missingList = implode(", ", "$_SESSION['missing']");
echo "<p>The following required field(s) are missing: $missingList. <br />Please fill them out below.</p>";
}
?>
---------And the script below is from previous page. (there are 2 other pages to ask name and age before this page. )-----------
session_start();
if (!isset($_SESSION['formStarted'])) {
header('Location: multiple01.php');
exit;
}
// each page needs a different name for the submit button
if (array_key_exists('Submit3', $_POST)) {
include('shared.php');
nukeMagicQuotes();
// set required fields
// must be an array, even if only one item is required
// if no fields are required, an empty array is needed
// otherwise, in_array() later in the script will generate an error
$required = array('address');
// create empty array for any missing fields
//$missing = array();
// process the $_POST variables and save them in the $_SESSION array
foreach ($_POST as $key => $value) {
// assign to temporary variable and strip whitespace if not an array
$temp = is_array($value) ? $value : trim($value);
// if empty and required, add to $missing array
if (empty($temp) && in_array($key, $required)) {
array_push($_SESSION['missing'], $key);
}
// otherwise, assign to a variable of the same name as $key
else {
$_SESSION[$key] = $temp;
}
}
// if no required fields are missing, redirect to next page
//if (!$missing) {
header('Location: multiple04.php');
exit;
//}
}
?>
