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。
