我正在尝试在商店内容之前添加自定义内容,但是仅当查看具有该类别子项的特定类别的产品时。
鞋子类别为:主要类别-'活动',子类别-'研讨会','课程'和'训练”。
add_action( 'woocommerce_before_shop_loop', 'eventsTerms', 18);
function eventsTerms() {
$term = get_term_by('name', 'events', 'product_cat');
$term_id = $term->term_id;
$taxonomyName = 'product_cat';
$termChildren = get_term_children( $term_id, $taxonomyName );
foreach ( $termChildren as $child ) {
$_term = get_term_by( 'id', $child, $taxonomyName );
$childTerms= ', "' . '' . $_term->name . '"';
echo $childTerms; // only to see is ok
}
if ( is_product_category( array("events", $childTerms) ) ) {
global $product;
wp_list_categories(
array(
'show_option_all' => 'show all',
'taxonomy' => 'product_cat',
'style' => 'none',
'separator' => '',
'hide_empty' => 0,
));
}
}
$childTerms
返回所有子类别名称,因此我想将is_product_category
条件标记与数组一起使用,但我的代码仍仅适用于主类别“事件”。
错误在哪里?

好的,我认为implode
不能在is_product_category()
参数中使用它的原因。所以我尝试像这样json_encode
:
add_action( 'woocommerce_before_shop_loop', 'eventsTerms', 18);
function eventsTerms() {
$term = get_term_by('name', 'events', 'product_cat');
$term_id = $term->term_id;
$taxonomyName = 'product_cat';
$termChildren = get_term_children( $term_id, $taxonomyName );
foreach ( $termChildren as $child ) {
$_term = get_term_by( 'id', $child, $taxonomyName );
$childTerms[] = " '".$_term->name."'";
}
$x = implode(",", $childTerms);
$y = json_encode($x);
echo $y; // output as " 'seminarium', 'course', 'training'"
$y2 = preg_replace('/"([a-zA-Z]+[a-zA-Z0-9_]*)":/','$1:', $x); // removing qutes by preg_replace
echo $y2; // output as 'seminarium', 'course', 'training'
if ( is_product_category( array('events', $y) ) ) {
global $product;
wp_list_categories(
array(
'show_option_all' => 0,
'taxonomy' => 'product_cat',
'style' => 'none',
'separator' => '',
'hide_empty' => 0,
'child_of' => $term_id,
));
}
}
答案 0 :(得分:0)
函数get_term_by()
不适用于"id"
,却不适用于"term_id"
(或"slug"
或{{1 }})。
函数get_term_children()
提供了一组术语ID 。
条件函数is_product_category()
接受术语名称,子词或ID的数组,因为它基于is_tax()
函数。
您使事情变得比原本应该复杂的多,并且不需要foreach循环。
1)在“存档”页面上:
"name"
所以在您的代码中:
$term_slug = 'events';
$taxonomy = 'product_cat';
$term_id = get_term_by( 'slug', $term_slug, $taxonomy )->term_id; // Get the term ID
$child_ids = get_term_children( $term_id, $taxonomy ); // Get the children terms IDs
$terms_ids = array_merge( $child_ids, array($term_id) ); // an array of all term IDs (main term Id and it's children)
if ( is_product_category( $terms_ids ) ) {
// Do something
}
代码进入活动的子主题(活动的活动主题)的functions.php文件中。经过测试并可以工作。
2)在产品页面,购物车项目或订单项目上 (而不是存档页面):
您将使用条件函数has_term()
,该函数还接受术语名称,段或ID的数组。(第三个参数(可选)是WooCommerce产品的帖子ID或产品ID):
add_action( 'woocommerce_before_shop_loop', 'eventsTerms', 18 );
function eventsTerms() {
$term_slug = 'events';
$taxonomy = 'product_cat';
$term_id = get_term_by( 'slug', $term_slug, $taxonomy )->term_id; // Get the term ID
$child_ids = get_term_children( $term_id, $taxonomy ); // Get the children terms IDs
$terms_ids = array_merge( $child_ids, array($term_id) ); // an array of all term IDs (main term Id and it's children)
if ( is_product_category( $terms_ids ) ) {
global $product;
wp_list_categories( array(
'show_option_all' => 'show all',
'taxonomy' => 'product_cat',
'style' => 'none',
'separator' => '',
'hide_empty' => 0,
'child_of' => $term_id,
) );
}
}
