为什么我的循环不能动态获取正确的类别并显示所有已分类的帖子？

Objective: 单击类别时，我希望该类别。php页面，动态拉入该点击类别下的所有帖子。

示例：新闻->（操作：单击）->类别=新闻

目前，我的循环从类别中引入了3篇帖子：无论单击哪个类别，都是未分类的。我检查了我的循环和参数，似乎一切都应该按预期进行。如果能有新的眼光，我将不胜感激。

类别。PHP

<?php get_header(); ?>
<section class="component" role="main">
<header class="header">
<h1 class="entry-title"><?php single_cat_title(); ?></h1>
<?php if ( \'\' != category_description() ) echo apply_filters( \'archive_meta\', \'<div class="archive-meta">\' . category_description() . \'</div>\' ); ?>
</header>
<section class="component responsive">
<?php
$paged = ( get_query_var( \'paged\' ) ) ? get_query_var( \'paged\' ) : 1;

// Grabs the selected category
foreach((get_the_category()) as $category)
{
    $postcat= $category->cat_ID;
}

$args = array(
           \'posts_per_page\' => 7,
           \'paged\' => $paged,
           \'cat\' => $postcat // Passes the selected category to the arguments
        );

$custom_query = new WP_Query( $args );
$post_number = 0;


if ( $custom_query->have_posts() ) : while($custom_query->have_posts()) : $custom_query->the_post(); ?>
        <?php the_title(); ?>
    <?php endwhile; else : ?>
<?php endif; ?>
    <div class="clear"></div>
    <?php if (function_exists("pagination")) {
        pagination($custom_query->max_num_pages);
    } ?>
    </section>
</section>

$args = array( \'posts_per_page\' => 7, \'paged\' => $paged, \'cat\' => $postcat // Passes the selected category to the arguments ); $custom_query = new WP_Query( $args );

function limit_category( $query ) { if ( $query->is_category() && $query->is_archive() && $query->is_main_query() ) { $query->set( \'posts_per_page\', \'7\' ); } } add_action( \'pre_get_posts\', \'limit_category\' );

if ( have_posts() ) { // if we have posts while( have_posts() ) { // while we still have posts the_post(); // set the current post the_title(); // display its title the_content(); // display its content } // display the pagination links ?> <div class="nav-previous alignleft"><?php previous_posts_link( \'Older posts\' ); ?> </div> <div class="nav-next alignright"><?php next_posts_link( \'Newer posts\' ); ?></div> <?php } else { echo "<p>No posts found</p>"; }

Categories manage

我正在尝试向CPT中添加特定类别，只有在添加新帖子时，您才能看到与这些帖子类型相关的类别。此外，我希望能够从后端添加类别，而不是从代码添加类别，因为我有很多类别将要更改。如果有一个插件可以做到这一点，那很好，但我也希望了解它是如何做到的。非常感谢
