I'm new to PHP and I hope someone can help me. I have 4 PHP files and they are basically a form for the user to fill, then the system will navigate it to validate page, and user will click submit to save it. I have a problem in the checkbox part.
The error shows :
Notice: Array to string conversion in C:\xampp\htdocs\LM\LMvalidate_reservation.php
I have simplified the code to show only the checkbox part for easier understanding. I hope someone(s) can help me in this.
