在WooCommerce中product with
变量Id: 9
Id:9`。
通过下面的变体属性,我创建了多个产品变体。
然后,我想从父产品ID(<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
)和以下属性值中获取特定的产品变体:
pa_frame
您可以在下面找到该变体的屏幕截图:
我尝试了以下代码及其相应的结果。
为简单起见,目前仅尝试使用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
属性。
尝试1:
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
尝试2:
filterNot()
有关如何使用特定属性值返回所有变体的任何想法吗?
答案 0 :(得分:3)
变量产品中的产品属性在wp_postmeta数据库表中设置为元数据。然后您需要使用Meta查询而不是Tax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;
}
这应该按预期工作......
对于您的问题中列出的多个产品属性对(键/值),您只需在WP_Query
中使用它们:
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;
}
然后您将获得相应的产品变化(仅一个)......
注意:产品属性元键始于
attribute_pa_
,而不仅仅是pa_
