What Happens If an Expected Input Field Was Not Submitted
What Happens If an Expected Input Field Was Not Submitted? - PHP Script Tips - Processing Web Forms
✍: FYIcenter.com
Obviously, if an expected input field was not submitted, there will no entry in the $_REQUEST array for that field. You may get an execution error, if you are not checking the existence of the expected entries in $_REQUEST. For example, if you copy processing_forms.php to your local Web server, and run your browser with http://localhost/processing_forms.php?name=Joe, you will an error page like this:
You have submitted the following information: Name = Joe Comments = Thank you! PHP Notice: Undefined index: comment in ...\processing_forms.php on line 3
