WordPress 插件开发中,有时需要检索文章对应的自定义字段postmeta,这里写一下相关的代码段
$searchArgs = array( 'post_type' => 'post', 'meta_query' = array( 'relation' => 'AND', array( 'key' => 'srch_age', 'value' => $_REQUEST['srch_age'] ), array( 'key' => 'srch_ptype', 'value' => $_REQUEST['srch_ptype'] ) // ... Add as many other criteria as you need ) ); query_posts( $searchArgs ); while( have_posts() ): the_post(); ... endwhile;
