不同的posts_per_page取决于页码 [英] Different posts_per_page depending on page number

问题描述

下面的CODE A"用于排除类别.但我也想做到这一点:

"CODE A" below is used to exclude categories. But I also want to accomplish this:

如果是第 1-3 页，则显示 8 个帖子
如果是第 4 页或更多，则显示 9 个帖子

If is page 1-3, display 8 posts
If is page 4 or more, display 9 posts

如何实现?以及如何将其添加到代码 A"中?

How to accomplish this? And how can this be added into "CODE A" ?

.
代码 A

function exclude_categories($query){  
    if ( $query->is_home() && $query->is_main_query() ) {  
    $query->set( 'category__not_in', array(60, 61) );  
    }  
}  
add_action( 'pre_get_posts', 'exclude_categories' );  

推荐答案

我还不能测试它，但这可以工作

I'm not able to test it yet, but this could work

function exclude_categories($query){    
    $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; 

    if ( $paged < 4 ) :
        $query->set( 'posts_per_page', 8 );
    else :
        $query->set( 'posts_per_page', 9 );
    endif;

    if ( $query->is_home() && $query->is_main_query() ) {  
    $query->set( 'category__not_in', array(60, 61) );  
    }  
}  
add_action( 'pre_get_posts', 'exclude_categories' );  

也许你必须更换

Perhaps you have to replace

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1; 

与

global $paged; 
$paged = ( is_int($paged) && $paged !== 0 ) ? $paged : 1;
