How can I not get the o_id passed by get in if? is the. $ o_id incorrect? Please reply to the discussion (solution)

$ _ GET ['O _ id']

$ _ GET ['O _ id']

Still not available

Then your url must have o_id = ??? Is this an expression?
I couldn't find any of the poor information you provided.

It has nothing to do with the URL. the o_id has been passed and I have read the output. The o_id cannot be obtained in if.

What you are processing in if is form submission.
The o_id is transmitted by clicking the link.
There are two things at all!

Yes. how can we get the value?

Add a sentence


Then change the obtained location:
$ O_id = $ _ REQUEST ['O _ id'];

If the value is correct, you should pay more attention to the security of your statement:
$ O_id = (int) $ _ REQUEST ['O _ id'];
"Oid = '{$ oid }'"

Solved. thank you.
