[英]Get all the product variations for specific product attributes values in Woocommerce
In WooCommerce *(latest version)* I have one
variable product with
Id: 9`.在 WooCommerce
*(latest version)* I have one
Id: 9` 的可变product with
。
With the attributes for variation below I created multiple product variations.通过下面的变体属性,我创建了多个产品变体。
Then I wanna get an specific product variation, from the parent product id ( Id: 9
) and the following attribute values: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
Below you have an screenshot of that variation:下面是该变体的屏幕截图:
I have tried the following codes with their corresponding results.我已经尝试了以下代码及其相应的结果。 For simplicity, for now, just tried with the
pa_frame
attribute only.为简单起见,现在只尝试使用
pa_frame
属性。
Try 1: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
Try 2: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
Any idea on how to return all the variations with specific attribute values?关于如何返回具有特定属性值的所有变体的任何想法?
Product attributes in variable products are set as meta data in wp_postmeta database table.可变产品中的产品属性设置为wp_postmeta 数据库表中的元数据。 Then you will need to use a Meta query instead of a Tax query.
然后您将需要使用 Meta 查询而不是 Tax 查询。 Try this:
尝试这个:
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;
}
This should works as expected now…现在应该可以按预期工作了……
For your multiple product attributes pairs ( key / value ) as listed in your question you will just use them in your WP_Query
this way:对于您的问题中列出的多个产品属性对(键/值),您只需以这种方式在
WP_Query
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;
}
Then you will get normally the corresponding product variation (only one)…然后你通常会得到相应的产品变体(只有一个)......
Note: product attributes meta keys start all with
attribute_pa_
instead of justpa_
注意:产品属性元键全部以
attribute_pa_
开头,而不仅仅是pa_
