I encountered the following problems when using PHP to index games.


Games can be divided into the following types:


By region: mainland China, Hong Kong, Taiwan, Europe, America, and Korea

By Image: 3D 2.5D 2D

By type: role playing FPS shooting music horizontal combat

The expected result is:

After selecting, the "Hong Kong and Taiwan" option is selected as "Hong Kong and Taiwan. The current URL is www.aaa.com/game.php? Id = 3 & area = g
Continue to select. after selecting '3D ', the selected condition is: Port + 3D. the current URL is www.aaa.com/game.php? Id = 3 & area = g & pic = 3d
Continue to select, and then select 'assumer'. at this time, the selected condition is: Hong Kong and Taiwan + 3D + the current URL for assuming the role is www.aaa.com/game.php? Id = 3 & area = g & pic = 3d & type = role



How can this effect be achieved? How can the current URL be implemented as mentioned above.

------ Solution --------------------
You have used js or php.

Php:
When generating html, the url of the option is: $ _ SERVER [HOST] ......? . Implode ($ _ GET, array (key => value of the current option ))

Js:
Similarly, you only need to use js to process URLs.
------ Solution --------------------
To put it simply, the key = value of the current option is added to the end of the current url.
There is just a trick. when the key is the same, we need to overwrite it, instead of directly adding it to the back.
------ Solution --------------------
Click here to submit the data to the server and process the returned data to the specified url. Similar to 58 local processing.
It is mainly a set of url strings. Request. the response is the specified url. If you have selected all of them here. Three interactions
Js cannot change the browser address.
------ Solution --------------------
Use parse_str (array mode) and http_build_query ()
