获取 Woocommerce 中特定产品属性值的所有产品变体
Get all the product variations for specific product attributes values in Woocommerce
在 WooCommerce 中*(latest version)* I have one
变量product with
Id: 9`.
使用下面的变体属性,我创建了多个产品变体。
然后我想从父产品 ID (Id: 9
) 和以下属性值中获取特定的产品变体:
<attribute_for_variation>: <attribute_value_to_filter>
pa_size: size_8x10
pa_material: mat_luster_photo_paper
pa_frame: fra_silver_wood
pa_mat_usage: musa_yes
下面是该变体的屏幕截图:
我已经尝试了以下代码及其相应的结果。
为简单起见,现在,只尝试使用 pa_frame
属性。
尝试 1:
static function filterVariations() {
$query = [
'post_parent' => 9,
'post_status' => 'publish',
'post_type' => ['product_variation'],
'posts_per_page' => -1,
];
$result = [];
$wc_query = new \WP_Query($query);
while ($wc_query->have_posts()) {
$wc_query->next_post();
$result[] = $wc_query->post;
}
return $result;
}
// ---> RESULT: all the variations, that's OK
尝试2:
static function filterVariations() {
$query = [
'post_parent' => 9,
'post_status' => 'publish',
'post_type' => ['product_variation'],
'posts_per_page' => -1,
'tax_query' => [
'relation' => 'AND',
[
'taxonomy' => 'pa_frame',
'field' => 'slug',
'terms' => [ 'fra_silver_wood' ],
],
],
];
$result = [];
$wc_query = new \WP_Query($query);
while ($wc_query->have_posts()) {
$wc_query->next_post();
$result[] = $wc_query->post;
}
return $result;
}
// ---> RESULT: empty list
知道如何 return 具有特定属性值的所有变体吗?
可变产品 中的产品属性被设置为 wp_postmeta 数据库 table 中的元数据 。那么您将需要使用元查询而不是税务查询。试试这个:
static function filterVariations() {
$query = new \WP_Query( array(
'post_parent' => 9,
'post_status' => 'publish',
'post_type' => 'product_variation',
'posts_per_page' => -1,
'meta_query' => array( array(
'key' => 'attribute_pa_frame',
'value' => 'fra_silver_wood',
) ),
) );
$result = array();
if($query->have_posts()){
while ($query->have_posts()) {
$query->next_post();
$result[] = $query->post;
}
wp_reset_postdata();
}
wp_reset_query();
return $result;
}
现在应该可以正常工作了……
对于您问题中列出的多个产品属性对(键/值),您只需在 WP_Query
中以这种方式使用它们:
public function filterVariations() {
$query = new \WP_Query( array(
'post_parent' => 40,
'post_status' => 'publish',
'post_type' => 'product_variation',
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'attribute_pa_size',
'value' => 'size_8x10',
),
array(
'key' => 'attribute_pa_material',
'value' => 'mat_luster_photo_paper',
),
array(
'key' => 'attribute_pa_frame',
'value' => 'fra_silver_wood',
),
array(
'key' => 'attribute_pa_mat_usage',
'value' => 'musa_yes',
),
),
) );
$result = array();
if($query->have_posts()){
while ($query->have_posts()) {
$query->next_post();
$result[] = $query->post;
}
wp_reset_postdata();
}
wp_reset_query();
return $result;
}
那么你会正常得到对应的产品变体(只有一个)…
Note: product attributes meta keys start all with attribute_pa_
instead of just pa_
