Sorting with PHP and GET method? -

-

I'm trying to sort them using the link and the GET method. I provide the code first and then explain what I am trying to achieve. Could be a better way of using AJX and making it dynamic (I think?), But I want to start it already.

code: 

  if (isset ($ _ GET ['order'])) {$ order = $ _GET ['order'];} else {$ order = 0;} if (isset ($ _GET ['field'])) {$ order_field = $ _GET ['field'];} switch ($ order) {case 0: $ order_next = "DESC"; break; Case "DESC": $ order_next = "ASC"; break; Case "ASC": $ order_next = 0; break; }

And later, I have this snippet in the HTML page:

OK I have the Last link, which includes 3 terms, default , DESC command, Em> ASC command.
When I click on it once, it should be sent through the GET method, the field I clicked was the "last name" field, and I need the next position (by default (sorting Without the next one (DESC in this case)). I can not catch the error completely on the code, or I do not understand anything, can not the page be loaded properly or again? When I click on the link, the $ order and $ order_field are read from the GET method, but nothing else . For some reason switch does not work, and the $ order_next does not change in the new value, and there is only 1 link instead of 2:
Default: Link " Last "DESC: Link with the triangle picture indicating the" last "link.

PS: Sorry, if I did not understand this well, but I tried. Thanks for your time!

change case 0: to "0": and all the world will be good: -)

This is because using the switch

To understand, just run this code and see the results: 

  var_dump ("DESC" == 0);
