Registration procedures take a single entrance, the core judgment is checkip, only need to do a game_id judgment in the template program that is not real-name authentication. Because of too sure, eager to get off work, coupled with everyone urged nervous, suddenly fooled, made two mistakes: one is to judge the position of game_id in advance, resulting in many variables behind did not pass to the destination page; second, did not understand the meaning of header jump and include, directly used header to do jump.

The page redirected by header cannot inherit the variables and other elements of the previous page. Give an example:

A.php file

$userEname = "crystal"

$userCname = "Cheng Cheng"

/ / your code

..

Header ("location:b.php")

/ / your code

.

If you reference $userEname in the b.php file, what do you think the result is? All right, don't sell it anymore. At this time, $userEname = null. If you use include to include b.php, you can avoid the problem that $userEname is empty. Peng reminded me of that.
