  • 0

I have a form on a webpage which emails the details using the PHP mail() function. The form is quite long, and I also am including HTML formatting for the email.
The email sends fine if I don’t include all the form information, but when I try to include the whole form the email doesn’t get sent. It seems to stop working when I’m including too much information. As soon as I take some of the information out it works again, and it doesn’t matter which part of the information I remove.
I have tried the form on two different website hosts with the same problem. The content for the email is only about 300 lines long so I’m not sure if size is the issue.

Does anyone know what might be causing the problem?

here is my code for your reference

When I say “stop working” above, I mean simply that the mail() function returns false and does not send the email. The actual form works fine.

    When you come to that amount of HTML within a PHP-script it is useful to catch it in a variable instead of putting every single line in a $body variable.

    ob_start();
?>
<html>
   Your HTML.
</html>
<?
$body = ob_get_clean();

    This way you can easier see if there is something wrong with your message ruining the mail-function.
