可以使用wp\\u parse\\u args（）将参数合并到默认查询中

// Define the default query args
global $wp_query;
$defaults = $wp_query->query_vars;

// Your custom args
$args = array(\'cat\'=>-4);

// merge the default with your custom args
$args = wp_parse_args( $args, $defaults );

// query posts based on merged arguments
query_posts($args);

尽管如此，我认为更优雅的方法是使用pre\\u get\\u posts（）操作。这会在进行查询之前修改查询，以便查询不会运行两次。

基于该示例，我将把类别4从索引中排除，并将其放在函数中。php：

add_action(\'pre_get_posts\', \'wpa_44672\' );

function wpa_44672( $wp_query ) {

    //$wp_query is passed by reference.  we don\'t need to return anything. whatever changes made inside this function will automatically effect the global variable

    $excluded = array(4);  //made it an array in case you  need to exclude more than one

    // only exclude on the home page
    if( is_home() ) {
        set_query_var(\'category__not_in\', $excluded);
        //which is merely the more elegant way to write:
        //$wp_query->set(\'category__not_in\', $excluded);
    }
}
