I have this:
// If the form fields are empty, redirect to the error page.
elseif (empty($email_a ddress) || empty($comments )) {
header( "Location: error_message.h tml" );
}
I want to add another field to the string. How to do this? The additional field is "name".
Sorry. I'm a novice when it comes to PHP. I have an email form using a file "send_email.php ". My contact form simply contains:
Name
Email Address
Comments
If the fields are left empty on the contact form, the form returns an error page asking to answer all questions and resubmit. The php sample file I copied listed only 2 fields if "empty":
email address
comments
I want to add "name" to the string. Not knowing php code, I tried logic...which didn't work for me. Here's the contents of the php file:
