Today to share this article sorting effect of the implementation process.

In fact, the implementation process is also relatively simple, one is to construct the link, the other is to use query_posts to change the main loop on it.

In the index.php of the subject you need to insert the following code, used to output the Sort button HTML, the Sort button style, you write your own CSS again. Note that the following code automatically gets the sort method that the current user has selected and adds class= to the Sort button's Li

copy code

<ul>     <li>< A <?php if (isset ($_get[' order ')) && ($_get[' order ']== ' rand ')) echo ' class= ' the current ';?> href= '/?order=r and "rel=" nofollow "> Random reading </a></li>     <li><a <?php if isset ($_get[' Order '] && ($_get[' order ']== ' commented ')) echo ' class= ' the current ';?> href= '/?order=commented ' rel= ' Nofollow "> Comments max </a></li>     <li><a <?php if isset ($_get[' order ') && ($_get[' order ']== ' alpha ')] echo ' class= ' current ';?> href= '/?order=alpha ' rel= ' nofollow ' > title sort </ A></li> </ul>

Change the main loop
First you have to find the following statement in the index.php of the topic:

The code is as follows	Copy Code
if (Have_posts ())

Then add the following code before this sentence:

if (Isset ($_get[' order ')) { Switch ($_get[' order ') { Case ' rand ': $orderby = ' Rand '; Break Case ' commented ': $orderby = ' comment_count '; Break Case ' alpha ': $orderby = ' title '; Break Default: $orderby = ' title '; } Global $WP _query; $args = Array (' By ' => $orderby, ' order ' => ' DESC '); $arms = Array_merge ($args, $wp _query->query); Query_posts ($arms); } if (Have_posts ())

All right, that's it. Copy and paste, easy to achieve sorting effect
