Thank you very much, after hours of confusion I landed on this🎉🎉

For the people who get the problem "Undefined array key "updateid"...", what I did to solve it was change the form action, like we did in the lesson before. So instead of <form action="">, I wrote <form method="post">. Hope this helps!

Dear Khanam,

Thank you for your work and for explaining the code so clearly.

I have watched episodes 1 to 12 of your tutorial and successfully implemented them. I have one more question: If I want to update a table entry, it works as long as I update all fields of the entry. However, if I only want to change the mobile number, for example, and leave the other fields unchanged, I get an error message. Namely the following:
Warning: Undefined array key ‘data’ in on line 22

Fatal error: Uncaught TypeError: implode(): Argument #1 ($array) must be of type array, string given in Stack trace: #0 implode(‘, ’, NULL) #1 {main} thrown in on line 23

Could you please make an additional episode in the tutorial on how to solve this problem? That would be great. Best regards from Switzerland
