列出多个 $query->set 的正确方法 [英] Correct way to list multiple $query->set

问题描述

列出多个 $query->set 的正确方法是什么?我可以有多个 $query->set 像下面的CODE A"吗?
还是我应该将它们合二为一?如果是，您将如何组合三个 $query->set 代码?我尝试将它们组合在下面的CODE B"中，但没有用.

What is the correct way to list multiple $query->set ? Am I allowed to have multiple $query->set like "CODE A" below ?
Or am I supposed to combine them into one? If yes, how would you combine the three $query->set code? I tried combining them in "CODE B" below but it didn't work.

.
代码 A:在组合 $query->set 之前

这段代码在functions.php中

This code goes in functions.php

function featured_category( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
    $query->set( 'category_name', 'new' );
    $query->set( 'cat', '-60, -61' );
    $query->set( 'posts_per_page', 5 );
    }
}
add_action( 'pre_get_posts', 'featured_category' );

.
CODE B:合并后 $query->set

这段代码在functions.php中

This code goes in functions.php

function featured_category( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
    $query->set( array( 'category_name' => 'new', 'cat' => '-60, -61', 'posts_per_page' => 5) );
    }
}
add_action( 'pre_get_posts', 'featured_category' );

推荐答案

使用 set 方法(它是 WP_Query 类的一部分)的正确方法是传递 2 个参数 - 一个查询参数键和一个查询参数值.所以你的第一个例子(代码 A)是正确的方法.

The correct way to use the set method (which is part of the WP_Query class) is to pass 2 parameters - a query parameter key and a query parameter value. So your first example (CODE A) is the correct way to do it.

你可以在这里查看方法代码:https://core.trac.wordpress.org/browser/tags/4.0/src/wp-includes/query.php#L2328

附言如果要从查询中排除多个类别，请考虑使用 category__not_in 查询参数，例如:

P.S. If you want to exclude multiple categories from a query, consider using the category__not_in query parameters, for example:

$query->set( 'category__not_in', array(60, 61) );
