Problem redirecting upon form submission

**dgsignal** · 25 Jun 2008, 07:54 PM

I'm having trouble redirecting after having a user fill out a form. In order to test functionality of my redirect, I've created a simple form where a user enters an email address and a name. The form calls itself to do a simplified validation, and then gets redirected to another page. Problem is...the page will not redirect. As you can see from the enclosed code, I've tried both methods of redirection using header(location: URL) and zen_redirect(URL). Right now, the redirection does not occur and results in my form main_page being blank.

My form resides in my template in define_my_test_page.php.

Code:

<?
$message = "";
$emailclass = "basictext";
$username = "";

if ($_POST['process'] == 1) {

$pattern = '/.*@.*\..*/';
$email = $_POST['email'];
$urlname = urlencode($$_POST['username']);

if (preg_match($pattern, $_POST['email']) > 0) {
// Here's where you would store
// the data in a database...
header("location: index.php?main_page=my_product_home");
//zen_redirect("index.php?main_page=my_product_home");

}
$message = "Please enter a valid email address.";
$username = $_POST['name'];
$emailclass = "errortext";
}
?>

<html>
<style>
.basictext {
font-family: Arial, Helvetica, sans-serif;
font-size: 14px; color:#000066;
}
.errortext {
font-family: Arial, Helvetica, sans-serif;
font-size: 14px; color:#C00000; font-weight: bold;
}
</style>
<body>
<form action="index.php?main_page=my_test_page" method="post">
<? if ($message != "") {
print '<span class="errortext">'.
$message."<span><br>\n";
}
?>
<span class="<?print $emailclass; ?>">
Email address:</span>
<input name="email" type="text"
class="<? print $emailclass; ?>"><br>

<span class="basictext">Your name:</span>
<input name="name" type="text" class="basictext"
value="<?print $username; ?>"><br>
<input type="hidden" name="process" value="1">
<input type="submit" name="Button1" value="Sign up!">
</form>
</body></html>

Thanks for any help,

Dustin

Clarification: Even when I reduce the code in my define_my_test_page.php to the following, the redirect does not work. When I go to index.php?main_page=my_test_page, the main page is blank except for the header name. Obviously, redirects in this manner do not work.

Any suggestions for how to call a redirect from within define pages? I'm guessing I'm missing something simple.

Code:

<?php
zen_redirect("index.php?main_page=my_product_home");
?>

Have you tried ...?

?php
zen_redirect("my_product_home");
?>

Re: your first post, short tags are really not recommended.

Thanks for your reply.

Unfortunately, no luck with the change you recommended. Per your second recommendation, once I can get the redirect functionality working, I will make the change to get rid of my short tags.

I have attached a small snapshot of what my screen looks like when I load index.php?main_page=my_test_page. As you can see, the header title "my_test_page" shows up but is blank underneath.

Thanks DrByte. I'll download the error debugging utility and give it a try. In the meantime, could you (or anybody else) give me the proper way to redirect from within a define page?

Right now, all I have on my define redirect page is:

Code:

<?php zen_redirect("index.php?main_page=my_product_home"); ?>

I've eliminated anything extraneous to get the redirect functionality working.

Other than the usage of short tags, I am pretty sure this function call is written correctly. When I place the same function call in /modules/pages/my_test_page/header_php.php the redirect works fine. It seems to me that I simply don't know the correct way to redirect from within the define page, rather than the header. I've successfully written php scripts and redirected on other projects using header(location: $url) but something is different in this case.

Thanks again for all your help.
