將可變價格范圍替換為 WooCommerce 4+ 中選擇的可變價格

Question

在我們的 woocommerce 網站上，我試圖根據客戶從下拉菜單中選擇的變化來更新顯示的價格，如下所示：

我使用了 LoictheAztec 在另一個答案中提交的 php 函數：
用 WooCommerce 3 中選擇的變動價格替換可變價格范圍

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>';
}

However when a variation is selected it displays undefined underneath the From: $price as shown here:

因此，如果有人可以幫助我確定此錯誤的原因，以便現在根據已選擇的變化顯示和更新價格，我們將不勝感激。

2021 年 3 月更新（至少適用於 WooCommerce 3.7 至 5+）

編碼：

add_action('woocommerce_before_add_to_cart_form', 'selected_variation_price_replace_variable_price_range');
function selected_variation_price_replace_variable_price_range(){
    global $product;

    if( $product->is_type('variable') ):
    ?><style> .woocommerce-variation-price {display:none;} </style>
    <script>
    jQuery(function($) {
        var p = 'p.price'
            q = $(p).html();

        $('form.cart').on('show_variation', function( event, data ) {
            if ( data.price_html ) {
                $(p).html(data.price_html);
            }
        }).on('hide_variation', function( event ) {
            $(p).html(q);
        });
    });
    </script>
    <?php
    endif;
}

代碼位於活動子主題（或活動主題）的 functions.php 文件中。 測試和工作。

要使其與 Woocommerce 3.8 一起使用，您需要替換以下行：

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

到

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

更新代碼：

 // 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; $availiability = ''; } // Styles ?> <style> div.woocommerce-variation-price, div.woocommerce-variation-availability, div.hidden-variable-price { height: 0px !important; overflow:hidden; position:relative; line-height: 0px !important; font-size: 0% !important; } </style> <?php // Jquery ?> <script> jQuery(document).ready(function($) { var a = 'div.wc-availability', p = 'p.price'; $('input.variation_id').change( 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>'; }

希望能幫助到你！

該代碼不再起作用，我如何更改將對WooCommerce 3.8起作用的代碼，期待您的答復。 謝謝
