I’ve constructed this code from a hodge-podge of various sources and a couple weeks of what I would call ‘whole immersion learning’. In other words I don’t know squat about php and just thought I could fake it but apparently I can’t.
Anywho, I know what I’ve done below will send several who see it into paroxysm of utter horror at what I’ve done to your beloved php but it can’t be helped with only 2 weeks of self education and at least it only throws up three notices now rather than all the warnings, screaming warnings and fatal errors that it did in the past.
the last errors I’m getting are…
( ! ) Notice: Undefined variable: error_name in E:\wamp\www\complete-x013_php2\iframe1\contact.php on line 65
( ! ) Notice: Undefined variable: error_email in E:\wamp\www\complete-x013_php2\iframe1\contact.php on line 77
( ! ) Notice: Undefined variable: error_code in E:\wamp\www\complete-x013_php2\iframe1\contact.php on line 89

You need to add this :
just after :
Like this :
The notice is triggered because you are using .= on a undefined var.
