Question

在我们的woocommerce网站上，我试图根据客户从下拉菜单中选择的变化来更新显示的价格，如下所示：

我使用了由LoictheAztec在另一个答案中提交的php函数：
Replace the Variable Price range by the chosen variation price in WooCommerce 3

add_action( 'woocommerce_before_single_product', 'move_variations_single_price', 1 );
function move_variations_single_price(){
    global $product, $post;

    if ( $product->is_type( 'variable' ) ) {
        // removing the variations price for variable products
        remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );

        // Change location and inserting back the variations price
        add_action( 'woocommerce_single_product_summary', 'replace_variation_single_price', 10 );
    }
}

function replace_variation_single_price(){
    global $product;

    // Main Price
    $prices = array( $product->get_variation_price( 'min', true ), $product->get_variation_price( 'max', true ) );
    $price = $prices[0] !== $prices[1] ? sprintf( __( 'From: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );

    // Sale Price
    $prices = array( $product->get_variation_regular_price( 'min', true ), $product->get_variation_regular_price( 'max', true ) );
    sort( $prices );
    $saleprice = $prices[0] !== $prices[1] ? sprintf( __( 'From: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );

    if ( $price !== $saleprice && $product->is_on_sale() ) {
        $price = '<del>' . $saleprice . $product->get_price_suffix() . '</del> <ins>' . $price . $product->get_price_suffix() . '</ins>';
    }

    ?>
    <style>
        div.woocommerce-variation-price,
        div.woocommerce-variation-availability,
        div.hidden-variable-price {
            height: 0px !important;
            overflow:hidden;
            position:relative;
            line-height: 0px !important;
            font-size: 0% !important;
        }
    </style>
    <script>
    jQuery(document).ready(function($) {
        $('select').blur( function(){
            if( '' != $('input.variation_id').val() ){
                if($('p.availability'))
                    $('p.availability').remove();
                $('p.price').html($('div.woocommerce-variation-price > span.price').html()).append('<p class="availability">'+$('div.woocommerce-variation-availability').html()+'</p>');
                console.log($('input.variation_id').val());
            } else {
                $('p.price').html($('div.hidden-variable-price').html());
                if($('p.availability'))
                    $('p.availability').remove();
                console.log('NULL');
            }
        });
    });
    </script>
    <?php

    echo '<p class="price">'.$price.'</p>
    <div class="hidden-variable-price" >'.$price.'</div>';
}

但是，如果选择了变体，则会在From：$ price下方显示 undefined ，如下所示：

未定义错误的示例：

因此，如果有人可以帮我确定此错误的原因，以便现在根据已选择的变体显示和更新价格，我们将不胜感激。

更新3

我做了一些重大改进和改进......这个代码版本也解决了默认情况下为变量产品选择变体的情况（摆脱那个＆＃34; undefined＆＃34; bug ...） 并在特定情况下解决了其他一些错误。

注意 - 在某些情况下代码可能不起作用：对于某些主题或某些插件（例如德国市场）进行自己的更改，使用这些挂钩或更改默认的html结构。在某些情况下，您自己的自定义可能会有罪。

这是新代码：

// Utility function to get the default variation (if it exist)
function get_default_variation( $product ){
    $attributes_count = count($product->get_variation_attributes());
    $default_attributes = $product->get_default_attributes();
    // If no default variation exist we exit
    if( $attributes_count != count($default_attributes) )
        return false;

    // Loop through available variations
    foreach( $product->get_available_variations() as $variation ){
        $found = true;
        // Loop through variation attributes
        foreach( $variation['attributes'] as $key => $value ){
            $taxonomy = str_replace( 'attribute_', '', $key );
            // Searching for a matching variation as default
            if( isset($default_attributes[$taxonomy]) && $default_attributes[$taxonomy] != $value ){
                $found = false;
                break;
            }
        }
        // If we get the default variation
        if( $found ) {
            $default_variaton = $variation;
            break;
        }
        // If not we continue
        else {
            continue;
        }
    }
    return isset($default_variaton) ? $default_variaton : false;
}

add_action( 'woocommerce_before_single_product', 'move_variations_single_price', 1 );
function move_variations_single_price(){
    global $product, $post;

    if ( $product->is_type( 'variable' ) ) {
        // removing the variations price for variable products
        remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );

        // Change location and inserting back the variations price
        add_action( 'woocommerce_single_product_summary', 'replace_variation_single_price', 10 );
    }
}

function replace_variation_single_price(){
    global $product;

    // Main Price
    $prices = array( $product->get_variation_price( 'min', true ), $product->get_variation_price( 'max', true ) );
    $active_price = $prices[0] !== $prices[1] ? sprintf( __( 'From: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );

    // Sale Price
    $prices = array( $product->get_variation_regular_price( 'min', true ), $product->get_variation_regular_price( 'max', true ) );
    sort( $prices );
    $regular_price = $prices[0] !== $prices[1] ? sprintf( __( 'From: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );

    if ( $active_price !== $regular_price && $product->is_on_sale() ) {
        $price = '<del>' . $regular_price . $product->get_price_suffix() . '</del> <ins>' . $active_price . $product->get_price_suffix() . '</ins>';
    } else {
        $price = $regular_price;
    }

    // When a default variation is set for the variable product
    if( get_default_variation( $product ) ) {
        $default_variaton = get_default_variation( $product );
        if( ! empty($default_variaton['price_html']) ){
            $price_html = $default_variaton['price_html'];
        } else {
            if ( ! $product->is_on_sale() )
                $price_html = $price = wc_price($default_variaton['display_price']);
            else
                $price_html = $price;
        }
        $availiability = $default_variaton['availability_html'];
    } else {
        $price_html = $price;
        $availiability = '';
    }
    // Styles ?>
    <style>
        div.woocommerce-variation-price,
        div.woocommerce-variation-availability,

            overflow:hidden;
            position:relative;
            line-height: 0px !important;

    <?php // Jquery ?>
    <script>
    jQuery(document).ready(function($) {
        var a = 'div.wc-availability', p = 'p.price';

        $('select').blur( function(){
            if( '' != $('input.variation_id').val() ){
                if($(a).html() != '' ) $(a).html('');
                $(p).html($('div.woocommerce-variation-price > span.price').html());
                $(a).html($('div.woocommerce-variation-availability').html());
            } else {
                if($(a).html() != '' ) $(a).html('');
                $(p).html($('div.hidden-variable-price').html());
            }
        });
    });
    </script>
    <?php

    echo '<p class="price">'.$price_html.'</p>
    <div class="wc-availability">'.$availiability.'</div>
    <div class="hidden-variable-price" >'.$price.'</div>';
}

代码放在活动子主题（或活动主题）的function.php文件中。经过测试和工作。

在Woocommerce版本3.2.x，3.3.x和3.4.x中也进行了测试......

备注：

代码处理这些特定情况时：

定义了默认变体

所有变体都具有相同的正常价格

所有变体都具有相同的常规和促销价格

该代码还解决（在某些情况下）或增强：

更好的可用性html结构和显示（默认情况下）

加载时不再显示延迟

没有更多可用性重复错误

没有更多可用性＆＃34; undefined＆＃34;显示

Answer 2

要使其与Woocommerce 3.8一起使用，您需要替换以下行：

 $('select').blur( function(){

到

$('input.variation_id').change( function(){

更新的代码：

// Utility function to get the default variation (if it exist)
function get_default_variation( $product ){
    $attributes_count = count($product->get_variation_attributes());
    $default_attributes = $product->get_default_attributes();
    // If no default variation exist we exit
    if( $attributes_count != count($default_attributes) )
        return false;

    // Loop through available variations
    foreach( $product->get_available_variations() as $variation ){
        $found = true;
        // Loop through variation attributes
        foreach( $variation['attributes'] as $key => $value ){
            $taxonomy = str_replace( 'attribute_', '', $key );
            // Searching for a matching variation as default
            if( isset($default_attributes[$taxonomy]) && $default_attributes[$taxonomy] != $value ){
                $found = false;
                break;
            }
        }
        // If we get the default variation
        if( $found ) {
            $default_variaton = $variation;
            break;
        }
        // If not we continue
        else {
            continue;
        }
    }
    return isset($default_variaton) ? $default_variaton : false;
}
