可变产品属性:自定义每个显示的单选按钮文本值

因此，您将这个特定的单选按钮定位为显示自定义文本的 CSS 规则如下:

span.pa_tab-price {字体系列:拉托，无衬线；字体大小:中等；}span.pa_tab-option-blue, span.pa_tab-option-green,span.pa_tab-option-purple, span.pa_tab-option-orange {字体系列:拉托，无衬线；字体大小:中等；字体样式:正常；字体粗细:300；}span.pa_tab-option-blue {颜色:蓝色；}span.pa_tab-option-green {颜色:绿色；}span.pa_tab-option-purple {颜色:紫色；}span.pa_tab-option-orange {颜色为橙色;}

这只是一个例子

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

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;
}

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.

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

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

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

Thanks

2021 Update

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.

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…

Here is that revisited code:

// Custom function that get the variation id from product attribute option name
function get_variation_id_from_option_name( $term_slug, $taxonomy, $product_id ) {
    global $wpdb;

    return $wpdb->get_var( $wpdb->prepare( "
        SELECT pm.post_id
        FROM {$wpdb->prefix}postmeta pm
        LEFT JOIN {$wpdb->prefix}posts p ON pm.post_id = p.ID
        WHERE pm.meta_key LIKE '%s'
        AND pm.meta_value = '%s'
        AND p.post_parent = %d
    ", 'attribute_' . $taxonomy, $term_slug, $product_id ) );
}


// 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( $option_name ) {
    global $product;

    $taxonomy = 'pa_tab'; // HERE Define the targetted product attribute taxonomy pa_color
    
    $term     = get_term_by( 'name', $option_name, $taxonomy );

    if ( is_admin() || ! is_a( $term, 'WP_Term' ) || ! is_a( $product, 'WC_Product' ) ) {
        return $option_name;
    }

    $variation_id = get_variation_id_from_option_name( $term->slug, $taxonomy, $product->get_id() );

    if ( $variation_id > 0 ) {
        $variation  = wc_get_product( $variation_id );
        $price_html = wc_price( wc_get_price_to_display( $variation ) );

        if ( has_term( $option_name, $taxonomy, $product->get_id() ) ) {
            $output = ' <span class="'.$taxonomy.'-price">' . strip_tags( $price_html ) . '</span><span class="'.$taxonomy.'-'.$term->slug.'"> - ('.$option_name.')</span>';
        } else {
            $output = ' ' . $option_name;
        }
        return $output;
    }
    return $option_name;
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and works.

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>

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;
}

This is just an example
