Hey guys,
Thanks for the input! This is pretty nice, and DOES work. I like the fact
that the fields have been into an iterative array. It's a very elegant
solution. However the problem with this approach is that if you load the
page directly it works. But if you call the page from the index.php page
you get an initial error on all fields as they are all quite naturally
empty when you first load the page.
Here's the index.php page. All it is is HTML, no php:
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>LDAP Request Form</title>
<body>
<center><h3>LDAP Request Form</h3>
<form name="form_request" method="post" action="ldap.php"
onsubmit="return validateForm()">
<label for="requestor_email">Your Email Address:</label><br />
<input type="text" required id="requestor_email" name="requestor_email"
/><br /><br />
<label for="num_forms">How Many Forms Do You Need:</label><br />
<input type="text" required maxlength="2" size="5" id="num_forms"
name="num_forms" /><br /><br />
<input type="submit" name="submit" value="Submit" />
</form></center>
</body>
</html>
And here is ldap.php as was suggested:
<body>
<?php
if (isset($_POST['submit'])) {
$requestor_email = $_POST['requestor_email'];
$num_forms = $_POST['num_forms'];
}
echo "<center>You will be creating $num_forms accounts
today.</center><br />";
for($counter = 1;$counter<=$num_forms;$counter++) {
echo '<center><form name="ldap_accounts" method="post"
action="sendemail.php" onsubmit="return validateForm()">';
echo '<br /><br />';
echo "Enter user: $counter<br /><br />";
echo "<label for=\"first_name_.$counter.\">First Name:</label><br
/>";
echo "<input type=\"text\" id=\"first_name_.$counter.\"
name=\"first_name_.$counter.\" /><br /><br />";
echo "<label for=\"last_name_.$counter.\">Last Name:</label><br />";
echo "<input type=\"text\" id=\"last_name_.$counter.\"
name=\"last_name_.$counter.\" /><br /><br />";
echo "<label for=\"department_.$counter.\">Department:</label><br
/>";
echo "<input type=\"text\" id=\"department_.$counter.\"
name=\"department_.$counter.\" /><br /><br />";
echo "<label for=\"title_.$counter.\">Title:</label><br />";
echo "<input type=\"text\" id=\"title_.$counter.\"
name=\"title_.$counter.\" /><br /><br />";
echo "<label for=\"email_.$counter.\">Email:</label><br />";
echo "<input type=\"text\" id=\"email_.$counter.\"
name=\"email_.$counter.\" /><br /><br />";
echo "<label for=\"phone_$counter.\">Phone:</label><br />";
echo "<input type=\"text\" id=\"phone_.$counter.\"
name=\"phone_.$counter.\" /><br /><br />";
}
echo "<input type=\"hidden\" id=\"num_forms\" name=\"num_forms\"
value=\"$num_forms\" /><br /><br />";
echo "<input type=\"hidden\" id=\"requestor_email\"
name=\"requestor_email\" value=\"$requestor_email\" />";
echo "<input type=\"submit\" name=\"submit\" value=\"Create Ticket\" />";
echo "</form></center>";
?>
Why this happens when you call the ldap.php page from index.php but not
when you load the page directly beats me. But maybe someone can shed some
light on that?
Thanks!
