My code is not receiving the value of the variable at the time it is passed by GET / POST. And so at the time of inserting it into the bank, it receives 0.
Follow code of the form:

"My code is not receiving the value of the variable at the time it is passed by GET / POST" - Which variable ? Would that be
$_POST["insert"]to which you refer ?– Isac
What is the reason to use POST and GET together? I think you could submit it all by POST
– Mbosso
$passacod=$_GET["passcode"];
