Welcome aboard kateharp,
$products='$products';
$req='1';
$req does nothing and can be deleted. But the body of your message should have been "$products", and none of your other variables are set right, info below. When you single-quote, variables don't interpolate.
$products = 'blah';
echo $products; // prints "blah"
echo '$products'; // prints "$products"
echo "$products"; // prints "blah" - double quote to interpolate
Second, the variable "products" is never actually set to anything except when you do it here.
$products='$products';
Your form should point to your script, looks like you figured that out, but the two methods are post and get. Get gives you an ugly query string in the browser, and has some size limitations (not as much as it used to) but use post when you can
<form method="post" action="yourscript.php">
<textarea name="comments" id="comments"></textarea>
<!-- etc. -->
</form>
So your script looks for inclimg named elements in the form - for the above, it would look for comments:
$comments = $_POST['comments'];
Then the valid parameters of mail are to, subject, message body, with the from in the headers. Will get into that in a sec, but now you'd have
$sent=mail($to,$subject,
$comments,$headers);
See how that works? So populate your variables **something** like this (warning below.)
$to = 'company_email@example.com';
$email = $_POST['email']; // assuming form field named "email"
$comments = $_POST['comments'];
$subject='Company Name Site Inquiry';
$body = "
<p>Message from: $email</p>
<p>Message: $comments</p>
";
$headers = "From: $email\r\n";
$headers .= 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$sent=mail($to,$subject,
$body,$headers);
That will work . . . sorta.
There's a **big** catch to my "sorta." When you start setting up to accept user input, the first thing you should learn after getting it to work is filtering input and cleansing the input, forms are the prime target for spamming and hacking web sites. Dig around this site for many threads on this topic. Don't fall victim to "users of this site won't be doing any of that" - your users aren't the ones you have to worry about.
