两周前的WordPress查询

Question

以下查询返回一个星期，但我将如何进行查询，因此返回两个星期：

$columnists=new WP_Query(array('showposts'=>3, 'cat'=>66622, 'orderby'=>'rand','w'=>date('W'),'year'=>date('Y')));

Answer 1

Did you try this

'w'=>date('W')-1 

instead of

'w'=>date('W')

If it doasn't work here is the documentation of WP_Query function http://codex.wordpress.org/Class_Reference/WP_Query
