Wordpress loop show limit posts
提问by ray
This is the basic loop
这是基本循环
<?php while (have_posts()) : the_post(); ?>
<?php while (have_posts()) : the_post(); ?>
I want to show 20 posts on the search results page. I know we can change the value on admin panel options but it will change all i.e. index page and archive page etc. I need to have them differently.
我想在搜索结果页面上显示 20 个帖子。我知道我们可以更改管理面板选项上的值，但它会更改所有内容，即索引页面和存档页面等。我需要以不同的方式使用它们。

Great reference: http://codex.wordpress.org/The_Loop
很好的参考：http: //codex.wordpress.org/The_Loop
Just before you call the while statement, you need to query the posts. So:
就在调用 while 语句之前，您需要查询帖子。所以：
<?php query_posts('posts_per_page=20'); ?>
<?php while (have_posts()) : the_post(); ?>
<!-- Do stuff... -->
<?php endwhile;?>
EDIT: Sorry about the pagination, try this:
编辑：抱歉分页，试试这个：
<?php
global $query_string;
query_posts ('posts_per_page=20');
if (have_posts()) : while (have_posts()) : the_post();
?>
<!-- Do stuff -->
<?php endwhile; ?>
<!-- pagination links go here -->
<? endif; ?>

I find this solution and it works for me.
我找到了这个解决方案，它对我有用。
global $wp_query;
$args = array_merge( $wp_query->query_vars, ['posts_per_page' => 20 ] );
query_posts( $args );
if(have_posts()){
while(have_posts()) {
the_post();
//Your code here ...
}
}

Answers with new query inside template will not work correctly with custom post types.
在模板中使用新查询的答案将无法与自定义帖子类型一起正常工作。
But documentationoffers to hook on any query, check is it main query, and modify it before execution. That can be done inside template functions:
但是文档提供挂钩任何查询，检查它是主查询，并在执行前修改它。这可以在模板函数中完成：
function my_post_queries( $query ) {
// do not alter the query on wp-admin pages and only alter it if it's the main query
if (!is_admin() && $query->is_main_query()) {
// alter the query for the home and category pages
if(is_home()){
$query->set('posts_per_page', 3);
}
if(is_category()){
$query->set('posts_per_page', 3);
}
}
}
add_action( 'pre_get_posts', 'my_post_queries' );

You can limit the number of posts per loop through a $wp_query object. it takes multiple parameters for example:
您可以通过 $wp_query 对象限制每个循环的帖子数。它需要多个参数，例如：
<?php
$args = array('posts_per_page' => 2, 'post_type' => 'type of post goes here');
$query = new WP_Query( $args );
while( $query->have_posts()) : $query->the_post();
<!-- DO stuff here-->
?>

Add 'paged' => $paged Pagination would work!
添加 'paged' => $paged 分页会起作用！
<?php
$args = array('posts_per_page' => 2, 'paged' => $paged);
$query = new WP_Query( $args );
while( $query->have_posts()) : $query->the_post();
<!-- DO stuff here-->
?>
