Error_reporting (E_ALL &~ E_NOTICE );
Change
Error_reporting (E_ALL );
You may know.

Change the join Key of $ row to lowercase.

I tried it. the error message is:
Undefined index: submit... on line 28
Undefined index: submit... on line 33

28 rows are if (! $ _ REQUEST ['submit ']) receives the data submitted by the form.
However, there is no submit control in your form.

Upstairs, add name = submit to the input whose type is submit.

28 rows are if (! $ _ REQUEST ['submit ']) receives the data submitted by the form.
However, there is no submit control in your form.

So how should we change it?

Add a hidden input

Set

In general, set the input type to "submit. However, the value of the untitled submit button will not be submitted.
However, in your application, the operation method is determined by the submitted value button, so you must name
