WordPress 搜索文章自定义字段 search artilce postmeta

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;
