Wanting to eliminate the e-mail field from form

I'm working on a news tip line feedback form and I would like to remove the e-mail field. I don't need an e-mail field at all.

It doesn't matter with the other fields -- they can come and go, but for some reason the e-mail field affects the operation of the form if it's removed. I've used this setup on my new site several times just by tweaking it. In all those instances, I've always needed an e-mail field.

Any help in removing the e-mail field would be greatly appreciated.

<?php
/*
This is the e-mail address you want to send to.
*/
$webmaster_email = "My_Mail";

/*
These are the URLs of supporting pages.
*/
$feedback_page = "feedback_form.html";
$error_page = "error_message.html";
$thankyou_page = "thank_you.html";

/*
This loads the form field data into variables;
add additional fields here.
*/
$comments = $_REQUEST['comments'] ;
$name = $_REQUEST['name'] ;
$phone = $_REQUEST['phone'] ;
$email_address = $_REQUEST['email_address'] ;
/*
This checks for e-mail injection and carriage return
used by spammers to inject CC list.
*/
function isInjected($str) {
$injections = array('(\n+)',
'(\r+)',
'(\t+)',
'(%0A+)',
'(%0D+)',
'(%08+)',
'(%09+)'
);
$inject = join('|', $injections);
$inject = "/$inject/i";
if(preg_match($inject,$str)) {
return true;
}
else {
return false;
}
}

$body =
'Name: ' . $name .
PHP_EOL .
'E-mail: ' . $email_address .
PHP_EOL .
'Phone: ' . $phone .
PHP_EOL .
'Comments: ' . $comments;


// If user tries to access php script directly, redirect to the comment form.
if (!isset($_REQUEST['email_address'])) {
header( "Location: $feedback_page" );
}

// If any fields in form are empty, redirect to the error page.
elseif (empty($comments) || empty($name) || empty($phone) || empty($email_address)) {
header( "Location: $error_page" );
}

// If email injection is detected, go to error page.
elseif ( isInjected($email_address) ) {
header( "Location: $error_page" );
}

// Send email then redirect to the thank you page if all things met.
else {
mail( "$webmaster_email", "Feedback Form Results",
$body, "From: $email_address" );
header( "Location: $thankyou_page" );
}
?>

Do you want it to send an email, just post the message, or allow it even if they don't put in their email?

Hello myfayt,

Thank you for the reply. I would like to take the e-mail field completely out of my form, so that no identity is required. I would like only the Comments to be submitted, with Name being an option.

I've been successful changing around the form for other uses, but "email_address" appears in a lot of different areas on the php form and I don't understand why.

Here is a link to my page where I want to use only the Comments and Name fields.

The e-mail portion of the php should completely go away. Then I can take it out of my html.

Thank you for taking a look. I appreciate it.
