在 Woocommerce 获取定制产品属性

在 Woocommerce，我试图获得产品自定义属性值，但我失败了，我没有得到任何东西。

所以我试着:

global $woocommerce, $post, $product;
$res = get_post_meta($product->id);
print_r(unserialize($res['_product_attributes'][0]));

我得到了这些原始数据:

[pa_koostis] => Array
(
[name] => pa_koostis
[value] =>
[position] => 0
[is_visible] => 1
[is_variation] => 0
[is_taxonomy] => 1
)

我知道有一个值，因为它显示在属性部分，但是我就是找不到一种方法来使用我的自定义代码显示它。

You can get the single value for the attribute with below code:

$pa_koostis_value = get_post_meta($product->id, 'pa_koostis', true);

Edited: The woocommerce_get_product_terms is deprecated since Woocommerce version 3

Go with the following as @datafeedr wrote in his answer:

global $product;
$koostis = array_shift( wc_get_product_terms( $product->id, 'pa_koostis', array( 'fields' => 'names' ) ) );

or even more compact:

global $product;
$koostis = $product->get_attribute( 'pa_koostis' );

Original answer:

$result = array_shift(woocommerce_get_product_terms($product->id, 'pa_koostis', 'names'));

The answer to "Any idea for getting all attributes at once?" question is just to call function with only product id:

$array=get_post_meta($product->id);

key is optional, see http://codex.wordpress.org/Function_Reference/get_post_meta

woocommerce_get_product_terms() is now (2014) deprecated.

Use wc_get_product_terms() instead.

Example:

global $product;
$koostis = array_shift( wc_get_product_terms( $product->id, 'pa_koostis', array( 'fields' => 'names' ) ) );

September 2014:

$product->get_attribute( 'your_attr' );

You will need to define $product if it's not on the page.

Try this to get an array of attribute name => attribute value(s):

global $product;


$formatted_attributes = array();


$attributes = $product->get_attributes();


foreach($attributes as $attr=>$attr_deets){


$attribute_label = wc_attribute_label($attr);


if ( isset( $attributes[ $attr ] ) || isset( $attributes[ 'pa_' . $attr ] ) ) {


$attribute = isset( $attributes[ $attr ] ) ? $attributes[ $attr ] : $attributes[ 'pa_' . $attr ];


if ( $attribute['is_taxonomy'] ) {


$formatted_attributes[$attribute_label] = implode( ', ', wc_get_product_terms( $product->id, $attribute['name'], array( 'fields' => 'names' ) ) );


} else {


$formatted_attributes[$attribute_label] = $attribute['value'];
}


}
}


//print_r($formatted_attributes);


return $formatted_attributes;

It's little inefficient but does the trick.

Update for 2018. You can use:

global $product;
echo wc_display_product_attributes( $product );

To customise the output, copy plugins/woocommerce/templates/single-product/product-attributes.php to themes/theme-child/woocommerce/single-product/product-attributes.php and modify that.

Use below code to get all attributes with details

    global $wpdb;


$attribute_taxonomies = $wpdb->get_results( "SELECT * FROM " . $wpdb->prefix . "woocommerce_attribute_taxonomies WHERE attribute_name != '' ORDER BY attribute_name ASC;" );
set_transient( 'wc_attribute_taxonomies', $attribute_taxonomies );


$attribute_taxonomies = array_filter( $attribute_taxonomies  ) ;


prin_r($attribute_taxonomies);

Although @airdrumz solutions works, you will get lots of errors about you doing it wrong by accessing ID directly, this is not good for future compatibility.

But it lead me to inspect the object and create this OOP approach:

function myplug_get_prod_attrs() {
// Enqueue scripts happens very early, global $product has not been created yet, neither has the post/loop
global $product;
$wc_attr_objs = $product->get_attributes();
$prod_attrs = [];
foreach ($wc_attr_objs as $wc_attr => $wc_term_objs) {
$prod_attrs[$wc_attr] = [];
$wc_terms = $wc_term_objs->get_terms();
foreach ($wc_terms as $wc_term) {
array_push($prod_attrs[$wc_attr], $wc_term->slug);
}
}
return $prod_attrs;
}

Bonus, if you are performing the above early before the global $product item is created (e.g. during enqueue scripts), you can make it yourself with:

    $product = wc_get_product(get_queried_object_id());
