Woocommerce-在Frontend中显示带有短代码的单个产品属性 [英] Woocommerce - Display single product attribute(s) with shortcodes in Frontend
问题描述
最近几天我在这里阅读了许多问答，但是不幸的是，没有一个人解决了我的问题.
i've read many Q/A's here during the last few days, but unfortunately none of them solved my issue.
我正在尝试获取产品属性，并使用简码在前端显示它们.我设法显示所有可用属性并将它们显示在列表中，但是我只需要在不同位置选择一个或两个即可(这就是为什么要使用简码).例如[shortcode_attribute name ="brand"].
I'm trying to fetch product attributes and display them on the frontend with a shortcode. I have managed to display ALL available attributes and display them in a list, but i need to select only one or two of them in different locations (thats why using shortcodes). For example like [shortcode_attribute name="brand"].
我们非常感谢您的帮助！
Any help is highly appreciated!
到目前为止我的代码:
function tutsplus_list_attributes( $product ) {
global $product;
global $post;
$attributes = $product->get_attributes();
if ( ! $attributes ) {
return;
}
foreach ( $attributes as $attribute ) {
// Get the taxonomy.
$terms = wp_get_post_terms( $product->id, $attribute[ 'name' ], 'all' );
$taxonomy = $terms[ 0 ]->taxonomy;
// Get the taxonomy object.
$taxonomy_object = get_taxonomy( $taxonomy );
// Get the attribute label.
$attribute_label = $taxonomy_object->labels->name;
// Display the label followed by a clickable list of terms.
echo get_the_term_list( $post->ID, $attribute[ 'name' ] , '<div><li class="bullet-arrow">' . $attribute_label . ': ' , ', ', '</li></div>' );
}
}
add_action( 'woocommerce_product_meta_end', 'tutsplus_list_attributes' );
add_shortcode('display_attributes', 'tutsplus_list_attributes');
推荐答案
虽然我仍不是100％清楚您要寻找的内容，但我要创建的是一个简码，可创建所有术语的列表属性.为了更加灵活，我将添加对shortcode参数的支持，以便您可以创建特定属性术语的列表.
While I am still not 100% clear what you're after, what I'm going to create is a shortcode that creates a list of all terms in all attributes. To make it more flexible I'll add support for a shortcode parameter so you can create a list of specific attribute terms.
您需要从代码中更改的一件主要事情是，短代码需要返回一个字符串，而不是将HTML回显.回退简码可能会导致意外的怪异现象.
One major thing you need to alter from your code, is that shortcodes need to RETURN a string and not ECHO out html. Echoing out shortcodes can result in unexpected weirdness.
/**
* Attributes shortcode callback.
*/
function so_39394127_attributes_shortcode( $atts ) {
global $product;
if( ! is_object( $product ) || ! $product->has_attributes() ){
return;
}
// parse the shortcode attributes
$args = shortcode_atts( array(
'attributes' => array_keys( $product->get_attributes() ), // by default show all attributes
), $atts );
// is pass an attributes param, turn into array
if( is_string( $args['attributes'] ) ){
$args['attributes'] = array_map( 'trim', explode( '|' , $args['attributes'] ) );
}
// start with a null string because shortcodes need to return not echo a value
$html = '';
if( ! empty( $args['attributes'] ) ){
foreach ( $args['attributes'] as $attribute ) {
// get the WC-standard attribute taxonomy name
$taxonomy = strpos( $attribute, 'pa_' ) === false ? wc_attribute_taxonomy_name( $attribute ) : $attribute;
if( taxonomy_is_product_attribute( $taxonomy ) ){
// Get the attribute label.
$attribute_label = wc_attribute_label( $taxonomy );
// Build the html string with the label followed by a clickable list of terms.
// Updated for WC3.0 to use getters instead of directly accessing property.
$html .= get_the_term_list( $product->get_id(), $taxonomy, '<li class="bullet-arrow">' . $attribute_label . ': ' , ', ', '</li>' );
}
}
// if we have anything to display, wrap it in a <ul> for proper markup
// OR: delete these lines if you only wish to return the <li> elements
if( $html ){
$html = '<ul class="product-attributes">' . $html . '</ul>';
}
}
return $html;
}
add_shortcode( 'display_attributes', 'so_39394127_attributes_shortcode' );
用法:这将以2种方式之一使用.
Usage: This would be used in 1 of 2 ways.
首先，要显示特定属性，请使用:
First, to display specific attributes use:
[display_attributes attributes="color|material"]
第二，要显示所有属性，请使用:
Second, to display all attributes use:
[display_attributes]
修改
这里总是一个单一的显示版本:
Here's an always single display edition:
/**
* Attribute shortcode callback.
*/
function so_39394127_singular_attribute_shortcode( $atts ) {
global $product;
if( ! is_object( $product ) || ! $product->has_attributes() ){
return;
}
// parse the shortcode attributes
$args = shortcode_atts( array(
'attribute' => ''
), $atts );
// start with a null string because shortcodes need to return not echo a value
$html = '';
if( $args['attribute'] ){
// get the WC-standard attribute taxonomy name
$taxonomy = strpos( $args['attribute'], 'pa_' ) === false ? wc_attribute_taxonomy_name( $args['attribute'] ) : $args['attribute'];
if( taxonomy_is_product_attribute( $taxonomy ) ){
// Get the attribute label.
$attribute_label = wc_attribute_label( $taxonomy );
// Build the html string with the label followed by a clickable list of terms.
// Updated for WC3.0 to use getters instead of directly accessing property.
$html .= get_the_term_list( $product->get_id(), $taxonomy, $attribute_label . ': ' , ', ', '' );
}
}
return $html;
}
add_shortcode( 'display_attribute', 'so_39394127_singular_attribute_shortcode' );
这将删除所有HTML标记，因此您需要提供自己的...如果创建自定义列表，则会发生这种情况.
This removes all HTML markup, and so you'd need to provide your own... which would happen if you are making a custom list.
<ul>
<li class="arrow">Static List Item</li>
<li class="arrow">[display_attribute attribute="color"]</li>
<ul>
编辑:可以将此代码添加到主题的functions.php中，但最好在
EDIT: This code can be added to your theme's functions.php, but preferably either in a site-specific plugin or via the Code Snippets plugin.
