);
$categories = get_categories($args);

echo '<div class="one_fourth">';
echo '<h1 class="valignmiddle uppercase title-bold">'.$cat->name.'<img src="'.$cat->term_icon.'" alt="" class="alignleft"/>'.'<br />'.'<span class="solutions">'.$cat->description.'</span>'.'</h1>';

在我解决了这个问题之后。我认为这对你有帮助。
<?php
$args = array(
'orderby' => 'id',
'hide_empty'=> 0,
'child_of' => 5, //Child From Boxes Category
);
$categories = get_categories($args);
foreach ($categories as $cat) {
echo '<div style="width:20%;float:left;">';
echo '<h1 class="valignmiddle uppercase title-bold">'.$cat->name.'<img src="'.$cat->term_icon.'" alt="" class="alignleft"/>'.'<br />'.'<span class="solutions">'.$cat->description.'</span>'.'</h1>';
//echo '<br />';
$args2= array("orderby"=>'name', "category" => $cat->cat_ID); // Get Post from each Sub-Category
$posts_in_category = get_posts($args2);
foreach($posts_in_category as $current_post) {
echo '<span>';
?>
<li type='none' style='list-style-type: none !important;'><a href="<?=$current_post->guid;?>"><?='+ '.$current_post->post_title;?></a></li>
<?php
echo '</span>';
}
echo '</div>';

- Write for get all parent category
- Now do a foreach loop for them and get their child category.
Now under above foreach write another foreach using this get post for child category
$parent_cats = get_categories($args);foreach ( $parent_cats as $parent_cat) { $child_cats = some wp functions to get child cats of current parent category foreach ( $child_cats as $child_cat ) { $child_cat_post = get the post of child category } }
- 写入获取所有父类别
- 现在为他们做一个 foreach 循环并获取他们的子类别。
现在在上面的 foreach 下写另一个 foreach 使用这个 get post for child category
$parent_cats = get_categories($args);foreach ( $parent_cats as $parent_cat) { $child_cats = some wp functions to get child cats of current parent category foreach ( $child_cats as $child_cat ) { $child_cat_post = get the post of child category } }

Wordpress has <?php wp_dropdown_categories( $args ); ?>
WordPress 有 <?php wp_dropdown_categories( $args ); ?>
Example Usage (Dropdown without a Submit Button using JavaScript)
使用示例（使用 JavaScript 的没有提交按钮的下拉菜单）
<li id="categories">
<h2><?php _e( 'Posts by Category' ); ?></h2>
<?php wp_dropdown_categories( 'show_option_none=Select category' ); ?>
<script type="text/javascript">
<!--
var dropdown = document.getElementById("cat");
function onCatChange() {
if ( dropdown.options[dropdown.selectedIndex].value > 0 ) {
location.href = "<?php echo esc_url( home_url( '/' ) ); ?>?cat="+dropdown.options[dropdown.selectedIndex].value;
}
}
dropdown.onchange = onCatChange;
-->
</script>
</li>
