可变产品属性:自定义每个显示的单选按钮的文本值 [英] Variable product attribute: Customizing each displayed radio buttons text value

问题描述

在WooCommerce中，我正在使用 WC Variations单选按钮 插件(由8manos提供)，以将典型的下拉选择器替换为 Radio Buttons .

In WooCommerce I am using WC Variations Radio Buttons plugin (by 8manos) to replace the typical dropdown selectors with Radio Buttons.

我已将以下代码添加到我的子主题function.php中:

I've added the below code to my child themes function.php:

// Display the product variation price inside the variations dropdown.
add_filter( 'woocommerce_variation_option_name', 'display_price_in_variation_option_name' );

function display_price_in_variation_option_name( $term ) {
    global $wpdb, $product;

    if ( empty( $term ) ) return $term;
    if ( empty( $product->id ) ) return $term;

    $result = $wpdb->get_col( "SELECT slug FROM {$wpdb->prefix}terms WHERE name = '$term'" );

    $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 = $product->id";

    $variation_id = $wpdb->get_col( $query );

    $parent = wp_get_post_parent_id( $variation_id[0] );




    if ( $parent > 0 ) {
         $_product = new WC_Product_Variation( $variation_id[0] );
         return  '' ."<font size='3' face='Lato'>". wp_kses( woocommerce_price( $_product->get_price() ), array() ) . "<font size='3' color='red' face='Lato' style='normal' weight='300'>".' - ('.$term.')';

    }
    return $term;
}

我已经能够设置所有四个变体名称的样式，只是看是否可行. 尽管我需要将它们分别设置为4种不同的颜色.在这里，我可以提供一些帮助.

I've been able to style all four variation names just to see if it was possible. Although, I need each of them to be 4 different colours. That's where I can use some help.

下面的图像显示了我想要的内容(每个选项"使用不同的颜色):
忽略颜色"变体. 只需修改标签"变体.

The image below shows what I want (different colours for each "Option"):
Ignore "Color" variation. Just need to modify the "Tab" variation.

目前，四个单选中的每个选项的变体名称均为红色"，我希望每个选项都使用不同的颜色.

For the moment, the variation name in each of the four radio options is 'red', and I would like a different color for each.

要实现该目标，我需要更改什么代码?

What do I have to change in my code, to achieve that?

谢谢

推荐答案

以下是您重新访问的代码，该代码将仅在"Tab"属性单选按钮周围显示仅，而自定义显示的文本为 标记，该标记具有基于属性slug和 $term_slug 的组合的不同类别值.

Here is your revisited code that will display only around the "Tab" attribute radio buttons custom displayed text a <span> tag with a different class value based on a combination of the attribute slug and the $term_slug.

因此，您将能够将某些CSS样式颜色仅应用于显示为'pa_tab'属性的每个单选按钮的自定义文本，并将这些CSS规则添加到活动主题style.css…

So you will be able to apply some CSS style colors to each radio button displayed custom text for the 'pa_tab' attribute only, adding those CSS rules to your active theme style.css…

这是重新访问的代码:

// Display the product variation price inside the variations dropdown.
add_filter( 'woocommerce_variation_option_name', 'display_price_in_variation_option_name', 10, 1 );

function display_price_in_variation_option_name( $term ) {
    global $wpdb, $product;

    // Define HERE the targetted attribute taxonomy slug
    $tax_slug = 'pa_tab';

    // compatibility with WC +3
    $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

    if ( empty( $term ) || empty( $product_id ) )
        return $term;

    $result = $wpdb->get_var( "SELECT slug FROM {$wpdb->prefix}terms WHERE name = '$term'" );

    $term_slug = ( ! empty( $result ) ) ? $result : $term;

    $variation_id = $wpdb->get_var( "
        SELECT postmeta.post_id AS product_id
        FROM {$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 = $product_id
    ");

    $parent = wp_get_post_parent_id( $variation_id );

    if ( $parent > 0 ) {

        $_product = wc_get_product( $variation_id );

        if ( has_term( $term, $tax_slug, $_product->id) )
            $output = ' <span class="'.$tax_slug.'-price">' . wp_kses( woocommerce_price( $_product->get_price() ), array() ) . '</span><span class="' . $tax_slug . '-' . $term_slug . '"> - ('.$term.')</span>';
        else
            $output = ' ' . $term;

        return $output;

    }
    return $term;

}

代码会出现在您活动的子主题(或主题)的function.php文件或任何插件文件中.

此代码已经过测试并且可以正常工作.

This code is tested and works.

生成的html代码如下:

The generated html code is something like this:

<td class="value">
    <div>
        <input type="radio" name="attribute_pa_color" value="option-blue" id="pa_tab_v_option-blue">
        <label for="pa_tab_v_option-blue"> 
            <span class="pa_tab-price">$99.00</span>
            <span class="pa_tab-option-blue"> - (Option Blue)</span>
        </label>
    </div>
    <div>
        <input type="radio" name="attribute_pa_color" value="option-green" id="pa_tab_v_option-green">
        <label for="pa_tab_v_option-green"> 
            <span class="pa_tab-price">$299.00</span>
            <span class="pa_tab-option-green"> - (Option Green)</span>
        </label>
    </div>
    <!-- ... / ... ... -->                      
</td>

---

因此，您可以针对特定的单选按钮使用CSS规则来显示自定义文本，例如:

So you target this specific radio buttons displayed custom text with CSS rules something like:

span.pa_tab-price {
    font-family: lato, sans-serif; 
    font-size: medium;
}
span.pa_tab-option-blue, span.pa_tab-option-green,
span.pa_tab-option-purple, span.pa_tab-option-orange {
    font-family: lato, sans-serif; 
    font-size: medium;
    font-style: normal;
    font-weight: 300;
}
span.pa_tab-option-blue {
    color: blue;
}
span.pa_tab-option-green {
    color: green;
}
span.pa_tab-option-purple {
    color: purple;
}
span.pa_tab-option-orange {
    color: orange;
}

这只是一个例子
