覆盖新WP_QUERY中的POSTS_PER_PAGE

时间：2014-12-14 作者：kdev

我已经试了几个小时来解决这个问题。问题是，我有一个主题new WP_Query 设置循环。这很好用。

我想获取原始查询，修改它，然后使用另一个自定义查询来显示修改后的帖子列表。

除了\'posts_per_page\' 参数，该参数显示为正确设置（请参见下面的$args），但显示所有帖子。

这是我的代码：

目录搜索。php

    <?php
/**
 * @package WordPress
 * @subpackage Parent_Theme
 * @since Parent Theme 1.0
 *
 * Template Name: Directory Search
 */

get_header(); ?>

<section class="content" id="content">

<?php   
$i = 0;

$search_query = get_directory_search_query();

if ( $search_query->have_posts() ) : ?>

<?php                   
    // ---------------------------------------------------------------------------------
    // Clickable maps outside contained content area
    // --------------------------------------------------------------------------------- 
?>   
    <div class="bg-map">
        <?php include @ (\'includes/include-archive-map.php\'); ?>
    </div>

    <div class="container header-container">


        <!--    archive header -->
        <header class="page-header entry-header">

            <div class="header-inner">

                <h1 class="page-title">

                    <img src="<?php bloginfo( \'stylesheet_directory\' ); ?>/assets/css/images/the.png" alt="THE" class="the" />

                    SEARCH RESULTS

                <h2><?php echo $search_query->found_posts; ?> entrie(s) for "<?php 

                    $a = str_replace("-", " ", $a);
                    $t = str_replace("-", " ", $t);
                    switch (\'n\')
                    {
                    case ( $a !== \'\'  && $t !== \'\' && $p !== \'\' ) :
                        echo $a .\', \' . $t .\', \' . $p; break;

我已经尝试了我能想到的一切。我试过设置\'posts_per_page\' 尽可能使用参数。我试过使用\'showposts\', \'posts_per_archive_page\', 和\'nopaging\'.

我只是不明白一个新的查询，在正确设置参数的情况下，是如何表现为这样的。

谢谢你的帮助。

在你的垃圾堆里$args 在上面nopaging 设置为1 这将禁用分页（相当于posts_per_page = -1).

尝试将此设置为false 看看它是否能解决您的问题。然后，您可以查看设置的原因。

使用新的WP-Query()从循环中过滤后期格式；

嗨，我目前正在为我的博客构建一个主题。下面的代码指向最新的帖子（特色帖子）。因为这将有一个不同的风格比所有其他职位。然而我想过滤掉帖子格式：链接使用我在循环中定义的WP查询，因为它给我带来了更多的灵活性。我该怎么做呢？ <?php $featured = new WP_Query(); $featured->query(\'showposts=1\'); ?> <?php while ($featured->have_post
