Based heavily upon this email validation code (which works – I’ve tested it)

The code prints “parsed 2”, but doesn’t get much further.
function died runs, but only prints the additional generic message of “‘We are sorry, but there appears to be a problem with the form you submitted.”
Oddly !isset always seems to return true (regardless of what form information is in the form). I deleted all of the if !isset block, which caused the printing of “parsed 3”, “parsed 4”, “errortest1” and “The Email Address you entered does not appear to be valid.” Again, this was irrespective of whether or not the email address in the form met the stated condition. Removing the if!preg_match statements causes the generation of the error message
“Fatal error: Call to a member function prepare() on a non-object in
public_html/application4.php on line 88”
.
There are no syntax errors, or at least if there are any syntax errors they are generating merely logical errors.
imho you have changed names for
first_nameandlast_namefields, so below code should return false if all fields in the condition are set:
