Question

如何在Woocommerce中为product属性添加CSS类？例如，我需要通过以下方式显示每个属性的各个图标：before＆amp; ：在假元素之后。

提前致谢！

P.S。抱歉，推迟我认为你熟悉Woocommerce的语法。 Woocommerce也使用动作＆amp;钩子显示一些信息。例如，在产品页面上显示属性。我想用单独的图标显示Woocommcerce产品属性。现在我在content-product.php（woocomemrce模板中循环显示产品）中添加了php代码

/**
 * woocommerce_after_shop_loop_item_title hook.
 *
 * @hooked woocommerce_template_loop_rating - 5
 * @hooked woocommerce_template_loop_price - 10
 */
do_action( 'woocommerce_after_shop_loop_item_title' );
/** ATTRIBUTES BEGIN **/

// Get the attributes
$attributes = $product->get_attributes();
// Start the loop
foreach ( $attributes as $attribute ) : 

// Check and output, adopted from /templates/single-product/product-attributes.php
    if ( $attribute['is_taxonomy'] ) {
        $values = wc_get_product_terms( $product->id, $attribute['name'], array( 'fields' => 'names' ) );
        echo apply_filters( 'woocommerce_attribute', wpautop( wptexturize( implode( ', ', $values ) ) ), $attribute, $values );
    } else {
        // Convert pipes to commas and display values
        $values = array_map( 'trim', explode( WC_DELIMITER, $attribute['value'] ) );
        echo apply_filters( 'woocommerce_attribute', wpautop( wptexturize( implode( ', ', $values ) ) ), $attribute, $values );
    }

 endforeach; 
 /** ATTRIBUTES END **/

通过这种方法，我可以显示产品属性并为属性添加图标。但是我只能添加一个图标，因为在Woocommerce中没有为每个属性添加CSS类的功能。

我已经明白你需要为每个属性添加不同的类（对于CSS）。为此你必须在woocommerece中编辑以下php文件。在wordpress中转到 wp-content \ plugins \ woocommerce \ templates \ single-product 并打开 product-attributes.php 文件。替换以下代码。注意：您可以直接在插件中编辑，也可以将此文件复制到您的子主题中。

<?php
/**
 * Product attributes
 *
 * Used by list_attributes() in the products class.
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/product-attributes.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see 	    https://docs.woocommerce.com/document/template-structure/
 * @author 		WooThemes
 * @package 	WooCommerce/Templates
 * @version     3.1.0
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit;
}
?>
<table class="shop_attributes">
	<?php if ( $display_dimensions && $product->has_weight() ) : ?>
		<tr>
			<th><?php _e( 'Weight', 'woocommerce' ) ?></th>
			<td class="product_weight"><?php echo esc_html( wc_format_weight( $product->get_weight() ) ); ?></td>
		</tr>
	<?php endif; ?>

	<?php if ( $display_dimensions && $product->has_dimensions() ) : ?>
		<tr>
			<th><?php _e( 'Dimensions', 'woocommerce' ) ?></th>
			<td class="product_dimensions"><?php echo esc_html( wc_format_dimensions( $product->get_dimensions( false ) ) ); ?></td>
		</tr>
	<?php endif; ?>
   <?php
		//Here I added a variable for incrementing.
		$class_name=1;
	 ?>
	<?php foreach ( $attributes as $attribute ) : $class_name++; ?>
		<tr>
			<th class="my_classname_<?php echo $class_name++; ?>"><?php echo wc_attribute_label( $attribute->get_name() ); ?></th>
			<td><?php
				$values = array();

				if ( $attribute->is_taxonomy() ) {
					$attribute_taxonomy = $attribute->get_taxonomy_object();
					$attribute_values = wc_get_product_terms( $product->get_id(), $attribute->get_name(), array( 'fields' => 'all' ) );

					foreach ( $attribute_values as $attribute_value ) {
						$value_name = esc_html( $attribute_value->name );

						if ( $attribute_taxonomy->attribute_public ) {
							$values[] = '<a href="' . esc_url( get_term_link( $attribute_value->term_id, $attribute->get_name() ) ) . '" rel="tag">' . $value_name . '</a>';
						} else {
							$values[] = $value_name;
						}
					}
				} else {
					$values = $attribute->get_options();

					foreach ( $values as &$value ) {
						$value = make_clickable( esc_html( $value ) );
					}
				}

				echo apply_filters( 'woocommerce_attribute', wpautop( wptexturize( implode( ', ', $values ) ) ), $attribute, $values );
			?></td>
		</tr>
	<?php endforeach; ?>

如果要为Woocommerce特定属性值的eache分配CSS类，可以使用以下代码：

/** ATTRIBUTES BEGIN **/

// Get the attributes
$attributes = $product->get_attributes();
// Start the loop
foreach ( $attributes as $attribute ) : 

// Check and output, adopted from /templates/single-product/product-attributes.php
    if ( $attribute['is_taxonomy'] ) {
        $values = wc_get_product_terms( $product->id, $attribute['name'], array( 'fields' => 'names' ) );
        if($attribute['name'] == 'pa_usl_otpuska'){ 
        foreach($values as $value){ 
        $value_classname = $value; // how can I get the value name??
    }     
        echo apply_filters( 'woocommerce_attribute', wpautop( wptexturize('<span class="lbl ' . $value_classname . '">'. implode( '</span><span class="lbl ' . $value . '">', $values ).'</span>' ) ), $attribute, $values );
    } else {
  echo apply_filters( 'woocommerce_attribute', wpautop( wptexturize( implode( ', ', $values ) ) ), $attribute, $values );
    }
} else {

    // Convert pipes to commas and display values
       $values = array_map( 'trim', explode( WC_DELIMITER, $attribute['value'] ) );
    echo apply_filters( 'woocommerce_attribute', wpautop( wptexturize( implode( ', ', $values ) ) ), $attribute, $values );

    }
 endforeach; 
 /** ATTRIBUTES END **/

例如我在钩子之后将此代码添加到Woocomemrce - content-product.php：

do_action( 'woocommerce_after_shop_loop_item_title' );

并添加了一些这样的CSS代码：

.lbl.reciept:before{
    font-family: FontAwesome;
    content: "\f0f6";
    padding-right:10px;
    color:#FF9F41;
    font-size:25px;
}

）为属性添加CSS类
