最简单的方法是在查询和remove it 紧接着。
add_action(\'pre_get_posts\', \'some_function_in_functionsphp\');
$my_secondary_loop = new WP_Query(...);
remove_action(\'pre_get_posts\', \'some_function_in_functionsphp\');
if( $my_secondary_loop->have_posts() ):
while( $my_secondary_loop->have_posts() ): $my_secondary_loop->the_post();
//The secondary loop
endwhile;
endif;
wp_reset_postdata();
EDIT
您可以使用的另一种技术是设置自己的查询变量，并在挂钩中检查该变量：
// tell WordPress about our new query var
function wpse52480_query_vars( $query_vars ){
$query_vars[] = \'my_special_query\';
return $query_vars;
}
add_filter( \'query_vars\', \'wpse52480_query_vars\' );
// check if our query var is set in any query
function wpse52480_pre_get_posts( $query ){
if( isset( $query->query_vars[\'my_special_query\'] ) )
// do special stuff
return $query;
}
add_action( \'pre_get_posts\', \'wpse52480_pre_get_posts\' );
在模板中：
// set the query var (along with whatever others) to trigger the filter
$args = array(
\'my_special_query\' => true
);
$my_secondary_loop = new WP_Query( $args );
