Hello,
I wanted to educate myself about the the $_SESSION['insert_check'].session variable you introduced me to. So I wathed the database closely while stepping through the consecutive registration.php, data_update_initial.php, and login.php pages.
The registration.php inserts the login data properly into the database, the ID value being incremented above the current last record.
But hitting the submit button on the update_initial.php that loads next to update the record with further information unfortunately seems to overwrite the ID field with a '0'. I had not noticed this earlier, being simply happy that the pages loaded in the successive way I had wanted. I just resolved to come back and study everything more closely so I could follow the logic.
I am now not sure how to ensure that the correct ID number is preserved.
(There are no $_SESSION['SecurityAssistID'] values on the page, and so no 'double' error or whatever it was that previously arose).
Thank you once again,
KAB
