我正在寻找一种基于ACF选择字段在Woocommerce中遍历子类别的方法。本质上，Woocommerce类别将根据管理员选择的ACF字段分组在一起。 这里的https://imgur.com/a/OkKQZTu是向您显示类别菜单下的ACF字段的示例。
基本上，我希望结果显示如下：
基于ACF选择类别选择A的类别组：
基于ACF选择字段选择B的类别组：
基于ACF选择字段选择C的类别组：
到目前为止，这是我的代码。有了这段代码，我就能获得子类别的第一级及其显示的子类别。但是，再次，我不希望它们按其父类别分组。相反，我希望将它们按ACF选择字段选择进行分组。
<?php
$args = array(
'taxonomy' => 'product_cat',
'hide_empty' => false,
'parent' => 2342,
);
$product_cat = get_terms( $args );
foreach ($product_cat as $parent_product_cat)
{
echo '
<ul>
<li>
<a href="'.get_term_link($parent_product_cat->term_id).'">'.$parent_product_cat->name.'</a>
<ul>
';
$child_args = array(
'taxonomy' => 'product_cat',
'hide_empty' => false,
'parent' => $parent_product_cat->term_id,
);
$child_product_cats = get_terms( $child_args );
foreach ($child_product_cats as $child_product_cat)
{
echo '<li>-<a href="'.get_term_link($child_product_cat->term_id).'">'.$child_product_cat->name.'</a></li>';
}
echo '</ul>
</li>
</ul>';
}
?>
通过使用以下代码，我已经能够确认所选的ACF字段显示的是正确的结果：
<?php
$cat = get_field('associated_collection', 'category_2414');
echo '<p>'.($cat).'</p>'
?>
在这里，asssociated_collection是我的ACF字段，category_2414是父级Woocommerce类别。该代码显示了已选择的正确ACF字段。
关于我可能会缺少的东西或如何实现此目标的任何想法？
在此先感谢您的帮助。让我知道是否需要更清楚地排除故障。
我能够使用此代码显示类别，但我仍然想找到一种方法，根据选择的ACF字段（从“选择字段”选项中）将这些类别组合在一起。使用此代码，它显示为：
ACF字段A
ACF字段B
ACF字段A
我希望它看起来像这样：
ACF字段A
ACF字段B
<?php
$args = array(
'taxonomy' => 'product_cat',
'hide_empty' => 0
);
$c = get_categories($args);
$c_keep = array();
foreach($c as $cat){
if (get_field('associated_collection', 'category_'.$cat->term_id)) {
$c_keep[] = $cat; // forgot [] here
}
}
foreach($c_keep as $cat){
echo '<h1>'.get_field('associated_collection', 'category_'.$cat->term_id).'</h1>';
echo '<p>'.$cat->name.'</p>';
}
?>
有什么想法吗？
我已经修改了一些代码，现在尝试通过该数组循环的另一种方法：
<?php
function cat_loop() {
global $post;
global $wbdb;
$args = array(
'taxonomy' => 'product_cat',
'hide_empty' => 0
);
$c = get_categories($args);
$c_keep = array();
foreach($c as $cat){
if (get_field('associated_collection', 'category_'.$cat->term_id)) {
$c_keep[] = $cat;
}
}
foreach( $c_keep as $cat ) {
$subcat_args = array(
'post_type' => 'product',
'tax_query' => array(
array(
'taxonomy' => 'associated_collection',
'field' => 'slug',
'terms' => $cat,
),
),
);
print_r($c_keep);
$loop = null;
$loop = new WP_Query( $cat_args );
if ( $loop->have_posts() ) {
$count = 0;
while ( $loop->have_posts() ) {
$loop->the_post();
// Echo content here
$count++;
}
wp_reset_query();
} else echo 'Loop finished';
}
}
cat_loop();
?>
如您在上面所看到的（上面写着echo content here的地方，当循环准备就绪时，我被困在做什么/回声上。
print_r($c_keep)正在向我显示此内容：

关于如何在此循环中回显内容的任何想法？
