Ordering Wordpress posts with meta values
提问by user537137
I have this code below that basically creates 4 links to allow me to sort posts on the front end.
我在下面有这段代码，它基本上创建了 4 个链接，让我可以在前端对帖子进行排序。
<div class="sort">
Sort projects by:
<a href="http://mydomain.com/find-work/" >Latest Projects</a>
<a href="http://mydomain.com/find-work/?order=asc&orderby=date" >Ending Soon</a>
<a href="http://mydomain.com/find-work/?order=asc&orderby=meta_value_num&meta_key=proj_budget" >Budget Low</a>
<a href="http://mydomain.com/find-work/?order=desc&orderby=meta_value_num&meta_key=proj_budget" >Budget High</a>
</div>
<?php $my_query = new WP_Query( array(
'post_type' => 'project',
'orderby' => get_query_var('orderby'),
'order' => get_query_var('order'),
));
while ( $my_query->have_posts() ) : $my_query->the_post(); ?>
The second link, ordering by date works fine but the two links to order by meta values is not working. I am obviously missing something in my query but for the life of me can't work it out.
第二个链接，按日期排序工作正常，但按元值排序的两个链接不起作用。我显然在我的查询中遗漏了一些东西，但我一生都无法解决。
Any ideas??
有任何想法吗？？

It's a bit magical with meta values:
元值有点神奇：
$my_query = new WP_Query( array(
// 'post_type' => 'project',
'meta_key' => 'proj_budget',
'orderby' => 'meta_value_num'
));
All the possible values are explained in codex: http://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters
所有可能的值都在代码中进行了解释：http: //codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters

It's quite simple:
这很简单：
new WP_Query( array(
//I used meta_value_num below, because it's about a numeric field
//if you don't have a numeric field, just use meta_value
"orderby" => 'meta_value_num',
"meta_key" => 'price',
"order" => 'DESC'
));
