显示包含帖子的类别/子类别
显示包含帖子的类别/子类别
提问于 2017-06-15 15:35:00
基本上，正如标题所说，我希望获得类别和子类别的列表，然后是这些类别/子类别的帖子(带有链接)。
这是我试图实现的结构：
<ul>
<li>Category 1</li>
<ul>
<li>Subcategory 1 within category 1</li>
<ul>
<li>Post 1 within subcategory 1</li>
<li>Post 2 within subcategory 1</li>
<li>Post 3 within subcategory 1</li>
</ul>
<li>Subcategory 2 within category 1</li>
<ul>
<li>Post 1 within subcategory 2</li>
<li>Post 2 within subcategory 2</li>
<li>Post 3 within subcategory 2</li>
</ul>
<li>Subcategory 3 within category 1</li>
<ul>
<li>Post 1 within subcategory 3</li>
<li>Post 2 within subcategory 3</li>
<li>Post 3 within subcategory 3</li>
</ul>
<li>Posts that have no subcategory</li>
<ul>
<li>Post 1 with no subcategory</li>
<li>Post 2 with no subcategory</li>
</ul>
</ul>
<li>Category 2</li>
<ul>
<li>Subcategory 1 within category 2</li>
<ul>
<li>Post 1 within subcategory 1</li>
<li>Post 2 within subcategory 1</li>
<li>Post 3 within subcategory 1</li>
</ul>
<li>Subcategory 2 within category 2</li>
<ul>
<li>Post 1 within subcategory 2</li>
<li>Post 2 within subcategory 2</li>
<li>Post 3 within subcategory 2</li>
</ul>
<li>Subcategory 3 within category 2</li>
<ul>
<li>Post 1 within subcategory 2</li>
<li>Post 2 within subcategory 2</li>
<li>Post 3 within subcategory 2</li>
</ul>
<li>Posts that have no subcategory</li>
<ul>
<li>Post 1 with no subcategory</li>
<li>Post 2 with no subcategory</li>
</ul>
</ul>
</ul>到目前为止，在阅读了我能找到的关于这个主题的一切之后，我有了以下代码：
<ul>
<?php
$get_parent_cats = array(
'parent' => '0' //get top level categories only
);
$all_categories = get_categories( $get_parent_cats );//get parent categories
foreach( $all_categories as $single_category ){
//for each category, get the ID
$catID = $single_category->cat_ID;
echo '<li><a href=" ' . get_category_link( $catID ) . ' ">' . $single_category->name . '</a>'; //category name & link
$get_children_cats = array(
'child_of' => $catID //get children of this parent using the catID variable from earlier
);
$child_cats = get_categories( $get_children_cats );//get children of parent category
echo '<ul class="children">';
foreach( $child_cats as $child_cat ){
//for each child category, get the ID
$childID = $child_cat->cat_ID;
//for each child category, give us the link and name
echo '<a href=" ' . get_category_link( $childID ) . ' ">' . $child_cat->name . '</a>';
}
echo '</ul></li>';
} //end of categories logic ?>
</ul>现在，这段代码很好地显示了类别和子类别，但我需要以某种方式循环遍历我的帖子，并使用类别/子类别显示它们。我也尝试过使用休眠代码：
<?php
// get all the categories from the database
$cats = get_categories();
// loop through the categries
foreach ($cats as $cat) {
// setup the cateogory ID
$cat_id= $cat->term_id;
// Make a header for the cateogry
echo "<h2>".$cat->name."</h2>";
// create a custom wordpress query
query_posts("cat=$cat_id&posts_per_page=100");
// start the wordpress loop!
if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php // create our link now that the post is setup ?>
<a href="<?php the_permalink();?>"><?php the_title(); ?></a>
<?php echo '<hr/>'; ?>
<?php endwhile; endif; // done our wordpress loop. Will start again for each category ?>
<?php } // done the foreach statement ?>
</div><!-- #content -->
</div><!-- #container -->这段代码显示了所有类别和特定类别中的帖子，但结构不是我想要的结构。两天来，我一直在尝试将这两段代码组合在一起，但都没有得到我想要的结果。我没有使用Wordpress的经验，在这方面我真的需要帮助。

这是对任何感兴趣的人的解决方案：
<ul>
<?php
$get_parent_cats = array(
'parent' => '0' //get top level categories only
);
$all_categories = get_categories( $get_parent_cats );//get parent categories
foreach( $all_categories as $single_category ){
//for each category, get the ID
$catID = $single_category->cat_ID;
echo '<li><a href=" ' . get_category_link( $catID ) . ' ">' . $single_category->name . '</a>'; //category name & link
echo '<ul class="post-title">';
$query = new WP_Query( array( 'cat'=> $catID, 'posts_per_page'=>10 ) );
while( $query->have_posts() ):$query->the_post();
echo '<li><a href="'.get_the_permalink().'">'.get_the_title().'</a></li>';
endwhile;
wp_reset_postdata();
echo '</ul>';
$get_children_cats = array(
'child_of' => $catID //get children of this parent using the catID variable from earlier
);
$child_cats = get_categories( $get_children_cats );//get children of parent category
echo '<ul class="children">';
foreach( $child_cats as $child_cat ){
//for each child category, get the ID
$childID = $child_cat->cat_ID;
//for each child category, give us the link and name
echo '<a href=" ' . get_category_link( $childID ) . ' ">' . $child_cat->name . '</a>';
echo '<ul class="post-title">';
$query = new WP_Query( array( 'cat'=> $childID, 'posts_per_page'=>10 ) );
while( $query->have_posts() ):$query->the_post();
echo '<li><a href="'.get_the_permalink().'">'.get_the_title().'</a></li>';
endwhile;
wp_reset_postdata();
echo '</ul>';
}
echo '</ul></li>';
} //end of categories logic ?>
