在Woocommerce的单个产品页面上显示特定的自定义产品属性 [英] Display specific custom product attributes on single product pages in Woocommerce

问题描述

我发现以下代码可以在产品详细信息页面上显示所有自定义属性(具有我需要的特定的条形设计).该代码的工作原理很吸引人，我有适当的CSS可以显示自定义属性的水平条.

I found the following code to display all custom attributes on a product detail page (with a specific bar-style design that I need). The code works like a charm and I have the proper CSS to display horizontal bars of my custom attributes.

我遇到的问题是我只想显示特定的命名属性，并且不知道如何更改循环来做到这一点...

Problem I have is that I only want to display specific named attributes and don't know how to change the loop to do that...

function isa_woocommerce_all_pa(){

global $product;
$attributes = $product->get_attributes();

if ( ! $attributes ) {
    return;
}

$out = '<ul class="taste-attributes">';

foreach ( $attributes as $attribute ) {


    // skip variations
    if ( $attribute->get_variation() ) {
    continue;
    }
    $name = $attribute->get_name();
    if ( $attribute->is_taxonomy() ) {

        $terms = wp_get_post_terms( $product->get_id(), $name, 'all' );
        // get the taxonomy
        $tax = $terms[0]->taxonomy;
        // get the tax object
        $tax_object = get_taxonomy($tax);
        // get tax label
        if ( isset ( $tax_object->labels->singular_name ) ) {
            $tax_label = $tax_object->labels->singular_name;
        } elseif ( isset( $tax_object->label ) ) {
            $tax_label = $tax_object->label;
            // Trim label prefix since WC 3.0
            if ( 0 === strpos( $tax_label, 'Product ' ) ) {
               $tax_label = substr( $tax_label, 8 );
            }                
        }


        $out .= '<li class="' . esc_attr( $name ) . '">';
        $out .= '<p class="attribute-label">' . esc_html( $tax_label ) . ': </p> ';
        $tax_terms = array();
        foreach ( $terms as $term ) {
            $single_term = esc_html( $term->name );
            // Insert extra code here if you want to show terms as links.
            array_push( $tax_terms, $single_term );
        }
        $out .= '<span class="attribute-value">' . implode(', ', $tax_terms) . '</span><progress value="' . implode(', ', $tax_terms) .
        '" max="10"><div class="progress-bar"><span style="width:'
        . implode(', ', $tax_terms) . '0%">'
        . implode(', ', $tax_terms) . '</span></div></progress></li>';


        } else {
            $value_string = implode( ', ', $attribute->get_options() );
            $out .= '<li class="' . sanitize_title($name) . ' ' . sanitize_title( $value_string ) . '">';
            $out .= '<p class="attribute-label">' . $name . ': </p> ';
            $out .= '<progress value="' . esc_html( $value_string ) . '" max="10"></progress></li>';
        }
    }

    $out .= '</ul>';

    echo $out;
}
add_action('woocommerce_single_product_summary', 'isa_woocommerce_all_pa', 20);

推荐答案

在下面的代码中，您将首先在数组中定义所需的产品属性段，这些段将显示在单个产品页面中:

In the following code you will define first the desired product attributes slugs in an array, that will get displayed in single product pages:

add_action( 'woocommerce_single_product_summary', 'display_some_product_attributes', 25 );
function display_some_product_attributes(){
    // HERE define the desired product attributes to be displayed
    $defined_attributes = array('fyllighet', 'carrier', 'billing-e-number');

    global $product;
    $attributes = $product->get_attributes();

    if ( ! $attributes ) {
        return;
    }

    $out = '<ul class="taste-attributes">';

    foreach ( $attributes as $attribute ) {

        // Get the product attribute slug from the taxonomy
        $attribute_slug = str_replace( 'pa_', '', $attribute->get_name() );

        // skip all non desired product attributes
        if ( ! in_array($attribute_slug, $defined_attributes) ) {
            continue;
        }

        // skip variations
        if ( $attribute->get_variation() ) {
            continue;
        }

        $name = $attribute->get_name();

        if ( $attribute->is_taxonomy() ) {

            $terms = wp_get_post_terms( $product->get_id(), $name, 'all' );
            // get the taxonomy
            $tax = $terms[0]->taxonomy;
            // get the tax object
            $tax_object = get_taxonomy($tax);
            // get tax label
            if ( isset ( $tax_object->labels->singular_name ) ) {
                $tax_label = $tax_object->labels->singular_name;
            } elseif ( isset( $tax_object->label ) ) {
                $tax_label = $tax_object->label;
                // Trim label prefix since WC 3.0
                if ( 0 === strpos( $tax_label, 'Product ' ) ) {
                   $tax_label = substr( $tax_label, 8 );
                }                
            }

            $out .= '<li class="' . esc_attr( $name ) . '">';
            $out .= '<p class="attribute-label">' . esc_html( $tax_label ) . ': </p> ';
            $tax_terms = array();

            foreach ( $terms as $term ) {
                $single_term = esc_html( $term->name );
                // Insert extra code here if you want to show terms as links.
                array_push( $tax_terms, $single_term );
            }

            $out .= '<span class="attribute-value">' . implode(', ', $tax_terms) . '</span><progress value="' . implode(', ', $tax_terms) .
            '" max="10"><div class="progress-bar"><span style="width:'
            . implode(', ', $tax_terms) . '0%">'
            . implode(', ', $tax_terms) . '</span></div></progress></li>';

        } else {
            $value_string = implode( ', ', $attribute->get_options() );
            $out .= '<li class="' . sanitize_title($name) . ' ' . sanitize_title( $value_string ) . '">';
            $out .= '<p class="attribute-label">' . $name . ': </p> ';
            $out .= '<progress value="' . esc_html( $value_string ) . '" max="10"></progress></li>';
        }
    }

    $out .= '</ul>';

    echo $out;
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.

Code goes in function.php file of your active child theme (or active theme). Tested and works.
