Email form trouble

[katecarmstrong]

Hi - I have limited knowledge of PHP, but I have a form that I have used on a few sites, which is now giving me trouble. Can someone please help! I keep getting error messages when I click submit to test.

Here is the HTML:

	<form action="email.php" method="POST">

	<input type="hidden" value="[e-mail]" name="email">
	<input type="hidden" value="Mailing List Subscriber" name="subject">

	Email: <input type="text" name="email" />
	<input type="submit" value="submit" name="submit">

	</form>

Here is the PHP (email.php):

<?php
if(isset($_POST['submit'])) {

# Form declarations
$to = "[e-mail]"; 
$subject = "Mailing List Subscriber";
$from = "Mailing List Subscriber"; 
$name_field = $_POST['name']; 
$email_field = $_POST['email']; 

foreach($_POST['check'] as $value) { 
	$check_msg .= "$value\n"; 
} 

$body = "
E-Mail: $email_field\n"; 

$success = mail($to, $subject, $body, "From: \"$name_field\" <$email_field>");

}

if ($success){
header('Location: thankyouemail.html');
} else {
header('Location: emailerror.html');
}
?>

This is the error message:

Warning: Invalid argument supplied for foreach() in /home/livean5/public_html/f5/email.php on line 11

Warning: Cannot modify header information - headers already sent by (output started at /home/livean5/public_html/f5/email.php:11) in /home/livean5/public_html/f5/email.php on line 23

The email is sent, so it appears to be working somewhat, but the page I am redirected to gives the error message. I do have the thankyouemail.html and emailerror.html pages set up in the local directory.
Thanks to anyone who can help!

Shoot...I had everything working, but not it seems to be erroring out again. It takes me to the emailerror.html page and does not send an email submission.

Here is the HTML:
<form action="email.php" method="POST">
<font color="#EC008C">
<input type="hidden" value="[e-mail]" name="email">
<input type="hidden" value="Mailing List Subscriber" name="subject">

	Subscribe to our email list: <input type="text" name="email" />
	<input type="submit" value="submit" name="Subscribe">
	</font>
	</form>

Here is the PHP:
<?php
if(isset($_POST['submit'])) {

# Form declarations
$to = "[e-mail]"; 
$subject = "Mailing List Subscriber";
$from = "Mailing List Subscriber"; 
$name_field = $_POST['name']; 
$email_field = $_POST['email']; 


$body = "
E-Mail: $email_field\n"; 

$success = mail($to, $subject, $body, "From: \"$name_field\" <$email_field>");

}

if ($success){
header('Location: thankyouemail.html');
} else {
header('Location: emailerror.html');
}
?>

"seems to be" does that mean sometimes? or you don't know? or ...?

[katecarmstrong]

It errors out every time I 'submit'. Here is the link:

[dagon]

if(isset($_POST['submit'])) {

should be

if(isset($_POST['Subscribe'])) {

the array keys are the form input names
