如何在Woocommerce产品变体下拉列表中添加变体库存状态

标签: php wordpress woocommerce dropdown stock

我想显示Woocommerce产品页面变体下拉列表中显示的每种产品差异的库存状态(例如库存/缺货)。我已将相关功能复制到我的主题的functions.php文件中,并且可以编辑内容,但不确定如何为每个变体提取所需的库存状态。


// Updated Woocommerce Product Variation Select 

if ( ! function_exists( 'wc_dropdown_variation_attribute_options' ) ) {

    /**
     * Output a list of variation attributes for use in the cart forms.
     *
     * @param array $args
     * @since 2.4.0
     */

     /*

    function wc_dropdown_variation_attribute_options( $args = array() ) {
        $args = wp_parse_args( apply_filters( 'woocommerce_dropdown_variation_attribute_options_args', $args ), array(
            'options'          => false,
            'attribute'        => false,
            'product'          => false,
            'selected'         => false,
            'name'             => '',
            'id'               => '',
            'class'            => '',
            'show_option_none' => __( 'Choose an option', 'woocommerce' ),
        ) );

        $options               = $args['options'];
        $product               = $args['product'];
        $attribute             = $args['attribute'];
        $name                  = $args['name'] ? $args['name'] : 'attribute_' . sanitize_title( $attribute );
        $id                    = $args['id'] ? $args['id'] : sanitize_title( $attribute );
        $class                 = $args['class'];
        $show_option_none      = $args['show_option_none'] ? true : false;
        $show_option_none_text = $args['show_option_none'] ? $args['show_option_none'] : __( 'Choose an option', 'woocommerce' ); // We'll do our best to hide the placeholder, but we'll need to show something when resetting options.

        if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) {
            $attributes = $product->get_variation_attributes();
            $options    = $attributes[ $attribute ];
        }

        $html = '';
        $html .= '' . esc_html( $show_option_none_text ) . '';

        if ( ! empty( $options ) ) {
            if ( $product && taxonomy_exists( $attribute ) ) {
                // Get terms if this is a taxonomy - ordered. We need the names too.
                $terms = wc_get_product_terms( $product->get_id(), $attribute, array( 'fields' => 'all' ) );



                foreach ( $terms as $term ) {
                    if ( in_array( $term->slug, $options ) ) {
                        $html .= 'slug ) . '" ' . selected( sanitize_title( $args['selected'] ), $term->slug, false ) . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $term->name ) ) . ' ';
                    }
                }
            } else {
                foreach ( $options as $option ) {
                    // This handles lt 2.4.0 bw compatibility where text attributes were not sanitized.
                    $selected = sanitize_title( $args['selected'] ) === $args['selected'] ? selected( $args['selected'], sanitize_title( $option ), false ) : selected( $args['selected'], $option, false );

                    $html .= '' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option ) ) . '  Output Stock Details Here ';
                }
            }
        }

        $html .= '';

        echo apply_filters( 'woocommerce_dropdown_variation_attribute_options_html', $html, $args );
    }
}

我可以提取整个产品的库存水平,但现在可以提取每种变化。

非常感谢任何帮助。

更新2019 (仅适用于 1下拉的变量产品)

  

无论如何,当只有一个下拉选择字段时,确实有效(因此变体的一个属性)。

     

使用多个属性(因此多个下拉列表选择字段)会显示可能错误,具体取决于库存状态属性字词组合的变化。

我已经尝试了 Ali_k 的代码,但是当变量产品有多个下拉列表时,我的测试服务器中的无法正常工作

所以我对 Ali_k 的代码进行了一些更改,以使其在我的测试服务器(使用上一个WooCommerce版本)中运行。

要处理延期交货,请参阅:Add backorders stock status to Woocommerce variable product dropdown

代码:

// Function that will check the stock status and display the corresponding additional text
function get_stock_status_text( $product, $name, $term_slug ){
    foreach ( $product->get_available_variations() as $variation ){
        if($variation['attributes'][$name] == $term_slug ) {
            $stock = $variation['is_in_stock'];
            break;
        }
    }
    return $stock == 1 ? ' - (In Stock)' : ' - (Out of Stock)';
}

// The hooked function that will add the stock status to the dropdown options elements.
add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'show_stock_status_in_dropdown', 10, 2);
function show_stock_status_in_dropdown( $html, $args ) {
    // Only if there is a unique variation attribute (one dropdown)
    if( sizeof($args['product']->get_variation_attributes()) == 1 ) :

    $options               = $args['options'];
    $product               = $args['product'];
    $attribute             = $args['attribute']; // The product attribute taxonomy
    $name                  = $args['name'] ? $args['name'] : 'attribute_' . sanitize_title( $attribute );
    $id                    = $args['id'] ? $args['id'] : sanitize_title( $attribute );
    $class                 = $args['class'];
    $show_option_none      = $args['show_option_none'] ? true : false;
    $show_option_none_text = $args['show_option_none'] ? $args['show_option_none'] : __( 'Choose an option', 'woocommerce' );

    if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) {
        $attributes = $product->get_variation_attributes();
        $options    = $attributes[ $attribute ];
    }

    $html = '<select id="' . esc_attr( $id ) . '" class="' . esc_attr( $class ) . '" name="' . esc_attr( $name ) . '" data-attribute_name="attribute_' . esc_attr( sanitize_title( $attribute ) ) . '" data-show_option_none="' . ( $show_option_none ? 'yes' : 'no' ) . '">';
    $html .= '<option value="">' . esc_html( $show_option_none_text ) . '</option>';

    if ( ! empty( $options ) ) {
        if ( $product && taxonomy_exists( $attribute ) ) {
            $terms = wc_get_product_terms( $product->get_id(), $attribute, array( 'fields' => 'all' ) );

            foreach ( $terms as $term ) {
                if ( in_array( $term->slug, $options ) ) {
                    // HERE Added the function to get the text status
                    $stock_status = get_stock_status_text( $product, $name, $term->slug );
                    $html .= '<option value="' . esc_attr( $term->slug ) . '" ' . selected( sanitize_title( $args['selected'] ), $term->slug, false ) . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $term->name ) . $stock_status ) . '</option>';
                }
            }
        } else {
            foreach ( $options as $option ) {
                $selected = sanitize_title( $args['selected'] ) === $args['selected'] ? selected( $args['selected'], sanitize_title( $option ), false ) : selected( $args['selected'], $option, false );
                // HERE Added the function to get the text status
                $stock_status = get_the_stock_status( $product, $name, $option );
                $html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option ) . $stock_status ) . '</option>';
            }
        }
    }
    $html .= '</select>';

    endif;

    return $html;
}

代码放在活动子主题(或主题)的function.php文件中,或者放在任何插件文件中。

经过测试并使用变量产品只有一个变体属性 ...

enter image description here

使用Ali_K的代码,以下是变量产品的错误显示文字示例,其中包含多个选择字段 (因此变体的多个属性)

enter image description here

答案 1 :(得分:4)

好的,首先你需要得到这样的产品变体:

comboBox1.DataSource = list_of_companies
    .Select(c => new CBItem {
        Name = c.Name,
        Value = c.Id
    })
    .ToArray();

在内部选项循环中,您需要遍历变体并找到当前选项库存状态

$variations = $product->get_available_variations();

在变体循环之外,您需要添加库存和缺货变化的措辞

foreach ($variations as $variation) {
    if($variation['attributes'][$name] == $option) {
        $stock = $variation['is_in_stock'];

    }
}

然后更改html以包含其他变量($ stock_content)

if( $stock == 1) {
    $stock_content = ' - In stock';
} else {
    $stock_content = ' - Out of stock';
}

所以一个完整的函数将如下所示:

$html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( $option  .  $stock_content ) . '</option>'; 

答案 2 :(得分:1)

我修改了您的代码,以便仅在库存变化中显示下拉列表。我赚了$ stock return bool,然后

if ($stock_status){
            $html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option ) /*. $stock_status*/ ) . '</option>';
            }

如果您能想到一种更好的方法,将不胜感激。 P.S感谢您提供此解决方案,我无法相信这不是隐藏缺货变体的默认woocommerce行为。

@LoicTheAztec

我也一直在使用更新的代码来替换延期交货功能,但由于不存在函数调用而遇到错误。

get_the_stock_status()现在是 get_stock_status(),不是吗?

无论如何,下面的更新代码解决了该问题,以及由于上述错误而导致我无法加载礼品卡插件的问题。

// Function that will check the stock status and display the corresponding additional text
function get_stock_status_text( $product, $name, $term_slug ){
    foreach ( $product->get_available_variations() as $variation ){
        if($variation['attributes'][$name] == $term_slug ) {
            $is_in_stock = $variation['is_in_stock'];
            $backordered = get_post_meta( $variation['variation_id'], '_backorders', true );
            $stock_qty   = get_post_meta( $variation['variation_id'], '_stock', true );
            break;
        }
    }
    $stock_status_text = $is_in_stock == 1 ? ' - (In Stock)' : ' - (Out of Stock)';
    return $backordered !== 'no' && $stock_qty <= 0 ? ' - (On Backorder)' : $stock_status_text;
}

// The hooked function that will add the stock status to the dropdown options elements.
add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'show_stock_status_in_dropdown', 10, 2);
function show_stock_status_in_dropdown( $html, $args ) {

    // Only if there is a unique variation attribute (one dropdown)
