When you do validation of the form in the same script that shows the
form, the normal way to do this is
<?php
if (isset($_POST['submit'])) {
//
// validation here
//
}
?>
This won't work if you're getting to the page via another form, since
the $_POST['submit'] is set. There two ways of avoiding this:
1) use hidden fields in each form to indicate which form was submitted
2) use a different name for each form's submit button and use that in
the above code

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!

I'm trying to increase the connection timeout; but can't get it to work. Note:
Keep-Alive gets repeated.
I'm using:
header("Connection: Keep-Alive");
header("Keep-Alive: timeout=9, max=100");
I get:
(Status-Line) HTTP/1.1 200 OK

Set the second optional argument to "true"

I'm adding some minification to our cache.class.php and am running into an
edge case that is causing me grief.
I want to remove all comments of the // variety, HOWEVER I don't want to
remove URLs...
Given some example text here with carefully crafted cases:
// another comment here
<iframe src="http://foo.com";>
function bookmarksite(title,url){
if (window.sidebar) // firefox
window.sidebar.addPanel(title, url, "");
else if(window.opera && window.print){ // opera
var elem = document.createElement('a');
elem.setAttribute('href',url);
elem.setAttribute('title',title);
elem.setAttribute('rel','sidebar');
elem.click();
}
else if(document.all)// ie
window.external.AddFavorite(url, title);
}
I've tried so many variations and hunted on StackOverflow, Google, etc. and
what would seem like a task already solved, doesn't seem to be.
This is "close", but still matches //foo.com (omitting the : of course)
\s*(?!:)//.*?$ (count it as '/m' multiline)
This ultimately ends up in a PHP line of code like so:
$sBlob = preg_replace("@\s*//.*?$@m",'',$sBlob);
Here are some other links of stuff I've found and tried to experiment with
varying degrees.
