将附加文本添加到 Woocommerce 中的产品类别页面

Question

Woocommerce 有产品类别页面。它们的作用就像 WordPress 的常规类别页面，但针对的是产品而不是帖子。

在产品类别编辑器中有一个描述框，您可以在其中添加文本。查看产品类别页面时，文本将显示在类别页面标题下方。

我正在尝试找到一种方法来在产品下方添加内容。基本上，我想在该产品类别页面上的产品下方放置一篇 1,000 字的文章，以实现 SEO 目的。

但是，我不知道该怎么做。

要在产品下方的类别页面上显示文本，您需要将此代码添加到文件 wp-includes/functions.php 的开头，代码“mysql2date ($format, $date, $translate = true) {”之前

    add_action( 'init', 'wpm_product_cat_register_meta' );
/**
 * Register details product_cat meta.
 *
 * Register the details metabox for WooCommerce product categories.
 *
 */
function wpm_product_cat_register_meta() {
    register_meta( 'term', 'details', 'wpm_sanitize_details' );
}
/**
 * Sanitize the details custom meta field.
 *
 * @param  string $details The existing details field.
 * @return string          The sanitized details field
 */
function wpm_sanitize_details( $details ) {
    return wp_kses_post( $details );
}


add_action( 'product_cat_add_form_fields', 'wpm_product_cat_add_details_meta' );
/**
 * Add a details metabox to the Add New Product Category page.
 *
 * For adding a details metabox to the WordPress admin when
 * creating new product categories in WooCommerce.
 *
 */
function wpm_product_cat_add_details_meta() {
    wp_nonce_field( basename( __FILE__ ), 'wpm_product_cat_details_nonce' );
    ?>
    <div class="form-field">
        <label for="wpm-product-cat-details"><?php esc_html_e( 'Details', 'wpm' ); ?></label>
        <textarea name="wpm-product-cat-details" id="wpm-product-cat-details" rows="5" cols="40"></textarea>
        <p class="description"><?php esc_html_e( 'Detailed category info to appear below the product list', 'wpm' ); ?></p>
    </div>
    <?php
}


add_action( 'product_cat_edit_form_fields', 'wpm_product_cat_edit_details_meta' );
/**
 * Add a details metabox to the Edit Product Category page.
 *
 * For adding a details metabox to the WordPress admin when
 * editing an existing product category in WooCommerce.
 *
 * @param  object $term The existing term object.
 */
function wpm_product_cat_edit_details_meta( $term ) {
    $product_cat_details = get_term_meta( $term->term_id, 'details', true );
    if ( ! $product_cat_details ) {
        $product_cat_details = '';
    }
    $settings = array( 'textarea_name' => 'wpm-product-cat-details' );
    ?>
    <tr class="form-field">
        <th scope="row" valign="top"><label for="wpm-product-cat-details"><?php esc_html_e( 'Details', 'wpm' ); ?></label></th>
        <td>
            <?php wp_nonce_field( basename( __FILE__ ), 'wpm_product_cat_details_nonce' ); ?>
            <?php wp_editor( wpm_sanitize_details( $product_cat_details ), 'product_cat_details', $settings ); ?>
            <p class="description"><?php esc_html_e( 'Detailed category info to appear below the product list','wpm' ); ?></p>
        </td>
    </tr>
    <?php
}

add_action( 'create_product_cat', 'wpm_product_cat_details_meta_save' );
add_action( 'edit_product_cat', 'wpm_product_cat_details_meta_save' );
/**
 * Save Product Category details meta.
 *
 * Save the product_cat details meta POSTed from the
 * edit product_cat page or the add product_cat page.
 *
 * @param  int $term_id The term ID of the term to update.
 */
function wpm_product_cat_details_meta_save( $term_id ) {
    if ( ! isset( $_POST['wpm_product_cat_details_nonce'] ) || ! wp_verify_nonce( $_POST['wpm_product_cat_details_nonce'], basename( __FILE__ ) ) ) {
        return;
    }
    $old_details = get_term_meta( $term_id, 'details', true );
    $new_details = isset( $_POST['wpm-product-cat-details'] ) ? $_POST['wpm-product-cat-details'] : '';
    if ( $old_details && '' === $new_details ) {
        delete_term_meta( $term_id, 'details' );
    } else if ( $old_details !== $new_details ) {
        update_term_meta(
            $term_id,
            'details',
            wpm_sanitize_details( $new_details )
        );
    }
}

add_action( 'woocommerce_after_shop_loop', 'wpm_product_cat_display_details_meta' );
/**
 * Display details meta on Product Category archives.
 *
 */
function wpm_product_cat_display_details_meta() {
    if ( ! is_tax( 'product_cat' ) ) {
        return;
    }
    $t_id = get_queried_object()->term_id;
    $details = get_term_meta( $t_id, 'details', true );
    if ( '' !== $details ) {
        ?>
        <div class="product-cat-details">
            <?php echo apply_filters( 'the_content', wp_kses_post( $details ) ); ?>
        </div>
        <?php
    }
}

您将在类别属性中获得一个名为“详细信息”的附加字段。在此处添加您的文章，您将在类别页面的产品列表下方看到文本。这适用于每个类别。
