Why is there no variable in the php address bar returned by $ _ request?

{Code ...}

If ($ _ REQUEST ['Facebook _ type'] = 'Facebook ') {// pull out the facebook Photo window $ smarty-> assign ('Facebook _ type ', 'Facebook ') ;}$ $ (function () {if $ facebook_type eq 'Facebook'} openBg_login (". facebook_register_box "); // log on to the facebook pop-up window {/if}) when a user logs on to facebook, the link will appear? Facebook_type = facebook and then open the website on another computer. The address bar does not show? Facebook_type = facebook, but the window is displayed. Why is the window displayed? When no one logs on, the pop-up will not pop up. If one user logs on to facebook, the pop-up window will pop up by default when another user opens the page on another computer, why is there no facebook_type in the address bar or the smarty value assigned by entering the if statement?

The variable in the address bar is get, and there is no variable in the address bar to put data packets. When payload is post, requests are connected to both get and post.

The request should be submitted in post mode. Capture the packet and you will understand it.

Check post first. If post does not contain
$ _ REQUEST is used to connect all cookies! Not only get and post

$ _ REQUEST contains $ _ GET, $ _ POST, and $ _ COOKIE arrays by default. When running as a command line, argv and argc information are not included; they exist in the $ _ SERVER array.

Let's see what type $ _ REQUEST is accepted.

This variable accepts parameters in the request, including data in get, post, and cookie. If it is a parameter in post or cookie, the URL is certainly not reflected.
