Is there a problem with this code? Why not prompt that the administrator ID already exists if the administrator ID already exists? please try again.
------ Solution --------------------
The code cannot see any problem. Is your test accurate?
As for the $ row ['id'] you mentioned, it should be said that it is impossible
------ Solution --------------------
Replace the following code with print_r ($ row); for debugging. if there are still problems, send the debugging results.
Echo "";
