php - woocommerce 变体

Question

我正在创建一个 woocommerce 主题，并且我有产品变体，即显示在产品详细信息页面上的尺寸，但问题是我想通过使用产品 ID 在我的自定义 php 页面中获取所有变体，任何人都可以帮助我。

提前致谢。

Answer 1

您可以使用：$available_variations = $product->get_available_variations();

如果这是单个样式模板，请确保global $product;在顶部附近添加。

从那里，您可以遍历变化并按照您的意愿行事......因为您没有任何特定的输出，我希望这能让您走上正确的轨道。

Answer 2

您可以使用以下代码：

global $woocommerce, $product, $post;
// test if product is variable
if ($product->is_type( 'variable' )) 
{
    $available_variations = $product->get_available_variations();
    foreach ($available_variations as $key => $value) 
    { 
        //get values HERE  
    }
}

Answer 3

以下代码：

$variations = $product->get_available_variations();

将返回产品的所有变体

这个函数放在你显示所有变化的地方：

\wp-content\plugins\woocommerce\templates\single-product\add-to-cart\variable.php

Answer 4

一个常见问题通常始于更改单个产品的“有货”或“缺货”标签。那里的解决方案很少，您需要更改 functions.php 文件并添加新过滤器。

当您需要针对产品变化进行修改时，问题会变得更加复杂。

这可能是您的解决方案： http: //bucketpress.com/changeing-stock-availability-text-for-product-variations

为了显示产品的可用变体，您需要修改 variable.php 文件，该文件位于 /wp-content/plugins/woocommerce/templates/single-product/add-to-cart/

找到这个：

<form class="variations_form cart" method="post" enctype='multipart/form-data' data-product_id="<?php echo absint( $product->id ); ?>" data-product_variations="<?php echo htmlspecialchars( json_encode( $available_variations ) ) ?>">

在标记之前粘贴此代码：

foreach( $available_variations as $i => $variation ) {
//check if variation has stock or not 
if ( $variation['is_in_stock'] ) {
    // Get max qty that user can purchase
    $max_qty = $variation['max_qty'];

    // Prepare availability html for stock available instance
    $availability_html = '<p class="stock in-stock">' . $max_qty . ' units available for your purchase.' . '</p>';
} else {
    // Prepare availability html for out of stock instance
    $availability_html = '<p class="stock out-of-stock">Oops, we have no stock left.</p>';
}
$available_variations[$i]['availability_html'] = $availability_html; }

不要忘记从这一行移动 php 结束标记“？>”

do_action( 'woocommerce_before_add_to_cart_form' ); ?>

在你的新代码之后。

所以完整的 variable.php 文件应该像这样（WooCommerce 3.2.4）：

<?php
/**
 * Variable product add to cart
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/add-to-cart/variable.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see     https://docs.woocommerce.com/document/template-structure/
 * @author  WooThemes
 * @package WooCommerce/Templates
 * @version 3.0.0
 */
if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

global $product;

$attribute_keys = array_keys( $attributes );

do_action( 'woocommerce_before_add_to_cart_form' ); 

// Your New Code goes here:
foreach( $available_variations as $i => $variation ) {
    // check if variation has stock or not 
    if ( $variation['is_in_stock'] ) {
        // Get max qty that user can purchase
        $max_qty = $variation['max_qty'];

        // Prepare availability html for stock available instance
        $availability_html = '<p class="stock in-stock">Available: ' . $max_qty . '</p>';
    } else {
        // Prepare availability html for out of stock instance
        $availability_html = '<p class="stock out-of-stock">Out of stock!</p>';
    }
    $available_variations[$i]['availability_html'] = $availability_html;
} ?>

<form class="variations_form cart" method="post" enctype='multipart/form-data' data-product_id="<?php echo absint( $product->get_id() ); ?>" data-product_variations="<?php echo htmlspecialchars( wp_json_encode( $available_variations ) ) ?>">

尝试这个，

<?php
$name_size = get_post_meta($_GET['pr_id'],'product_size', true);
$t_shirt_sizes_array = wp_get_post_terms($_GET['pr_id'],'pa_size');
$t_shirt_size = array();
$t_shirt_price = array();
for($scnt = 0; $scnt < count($t_shirt_sizes_array); $scnt++){
$t_shirt_size[] = $t_shirt_sizes_array[$scnt]->name;
$t_shirt_price[] = $t_shirt_sizes_array[$scnt]->slug;
$t_shirt_size_id[] = $t_shirt_sizes_array[$scnt]->term_id;
}
$cnt = 1;
for($i = 0; $i < count($t_shirt_size); $i++){
$name_size = $t_shirt_size[$i];

$result = $wpdb->get_col( "SELECT slug FROM {$wpdb->prefix}terms WHERE name = 
'".$t_shirt_size[$i]."'" );
$term_slug = ( !empty( $result ) ) ? $result[0] : $term;
 $query = "SELECT postmeta.post_id AS product_id
    FROM {$wpdb->prefix}postmeta AS postmeta
LEFT JOIN {$wpdb->prefix}posts AS products ON ( products.ID = postmeta.post_id )
    WHERE postmeta.meta_key LIKE 'attribute_%'
        AND postmeta.meta_value = '$term_slug'
        AND products.post_parent = ".$_GET['pr_id'];    
$variation_id = $wpdb->get_col( $query );

$parent = wp_get_post_parent_id( $variation_id[0] );
if ( $parent > 0 ) {                    
    echo $name_size;
    $_product = new WC_Product_Variation( $variation_id[0] );
    echo $_product->get_price();
}
$price = $t_shirt_price[$i];
$cnt++;
}
?>
