----- Original Message ----- From: phplist_jsh Consider this statement related to Fields sent to PHP via an HTTP POST.
$A = $_POST["FieldName"]; If the page did not have a form field with FiledName, the result is that $A is empty. If the page DID have a form field with FieldName, but the field was left empty, then $A is empty also. How should I test $_POST to distinguish between these two conditions. James S. Huggins ----------------------------- Hi James, Use if(isset($_POST['FieldName'])) as it tests for the key rather that the value. This is also the better way to detect a submit on forms with multiple submit buttons ie name=submit1, name=submit2 as difererent browsers return different values for submit buttons. Rob.
