标签: php mysql woocommerce wpml

我正在开发一个与WordPress数据库一起使用的Web应用程序。在我的网站上(与WooCommerce和WPML合作)我有两种语言的产品 - 英语(第一),塞尔维亚语(第二)。我写了一个SQL代码,从数据库中获取产品,包括常规和销售价格等,但我想获得lang = en(英文版产品)的产品。问题是我不知道如何获得它们。

简单SQL:

$sql = 'SELECT * from `wp_posts` WHERE post_type = product';


这是SELECT from database:

的方法
// SELECT
public function select (
            $table_1 = ' wp_posts ', 
            $table_2 = ' wp_postmeta ', 
            $rows = ' t1.id, t1.post_title, guid, post_type ', 
            $where = ' t1.post_status = "publish" AND t1.post_type = "product" OR t1.post_type = "product_variation" ', 
            $groupby = ' t1.ID, t1.post_title '
        ) {

    // Connect to database and set charset
    $this->connect();
    $this->conn->set_charset('utf8');


    // Published products
    $sql = "SELECT $rows,
            max(case when meta_key = '_regular_price' then t2.meta_value end) AS price, 
            max(case when meta_key = '_sale_price' then t2.meta_value end) AS sale,
            max(case when meta_key = 'attribute_colors' then t2.meta_value end) AS colors,
            max(case when meta_key = 'attribute_number' then t2.meta_value end)
            FROM $table_1 AS t1
            INNER JOIN $table_2 AS t2 ON ( t1.ID = t2.post_id ) 
            WHERE $where
            GROUP BY $groupby";

    $result = mysqli_query($this->conn, $sql);
    $published_products_count = mysqli_num_rows($result);



    // Trashed products
    $trashed_sql = "SELECT post_status FROM `wp_posts`
                    WHERE post_status = 'trash'";

    $trashed_result = mysqli_query($this->conn, $trashed_sql);
    $trashed_products_count = mysqli_num_rows($trashed_result);


    // If results -> show them
    if ($result) {

        printf( "\t\t" . "<p>There are <strong>%d published</strong> products and <strong>%d trashed</strong>.</p>", $published_products_count, $trashed_products_count);

    $table = '
    <table class="pure-table pure-table-bordered">
        <thead>
            <tr>
                <th>Row. №</th>
                <th>ID</th>
                <th>Product</th>
                <th>Regular price</th>
                <th>Sale price</th>
                <th>Type</th>
                <th>Edit</th>
            </tr>
        </thead>';

        $row_number = 1;

        while ($row = $result->fetch_assoc()) {

            $table .= '
            <tr>
                <td>' . $row_number++ . '</td>
                <td>' . $row["id"] . '</td>
                <td><a href="http://www.enroll.rs/wp-admin/post.php?post=' . $row["id"] . '&action=edit" target="_blank">' . $row["post_title"] . '</a></td>
                <td class="price">' . $row["price"] . '</td>
                <td class="sale">' . $row["sale"] . '</td>
                <td>' . $row["post_type"] . '</td>
                <td><a href="edit_form.php?id=' . $row["id"] . '">Edit</a></td>
            </tr>';
        }

    $table .= '
    </table>';

        echo $table;
    }

    // If no results
    else {
        echo 'There isn't any products';
    }
}

我希望有人帮助我!

提前致谢! :)

P.S。该应用程序不是基于WordPress!

WPML插件创建了几个新表来管理multilang,而不影响标准WP帖子表。具体来说,它创建了wp_icl_translations表,用于存储帖子和语言之间的关系。

您需要在查询中添加两个新的JOIN语句:

JOIN wp_icl_translations t ON wp_posts.ID = t.element_id AND t.element_type = 'post_product' JOIN wp_icl_languages l ON t.language_code=l.code AND l.active=1

然后,您可以在 WHERE 语句中添加新条件,如下所示:

AND t.language_code='en'

希望这会有所帮助。 问候。
