How did you write your form?

It is necessary to output at the beginning of the code to see what the page has submitted.

Print_r ($ _ GET );
Print_r ($ _ POST );

If you do not want to see the error prompt, add
Error_reporting (E_ALL ^ E_NOTICE );

No problem with the code. the gsid cannot be obtained. is it from POST,
Can you get the value in this way.
$ _ REQUEST ['gsid ']
In addition, if the gsid is a number, we recommend that you use intval ($ _ REQUEST ['gsid.

If an error is found, you must add a parameter such as action = "dogdo. php? Id = 5 ". thank you for your enthusiastic discussion!
