我想開一張發(fā)票，客戶顯示在帶有 foreach 循環(huán)的表格中。數(shù)據(jù)是使用 PDO 從我的 SQL 數(shù)據(jù)庫(kù)中提取的，如下所示：include 'C:\xampp\htdocs\App\include\dbconnect.php';$sql = 'SELECT * FROM clienten WHERE verzekeraar = ?';$stmt = $database->prepare($sql);$stmt->execute(array($_SESSION["ROL"]));$clienten = $stmt->fetchAll(PDO::FETCH_ASSOC);foreach($clienten as $client) { 但是現(xiàn)在我在表格中創(chuàng)建了一個(gè)按鈕，當(dāng)它被按下時(shí)，你會(huì)被重定向到make_invoice.php并且數(shù)據(jù)被轉(zhuǎn)換為 PDF 以根據(jù)表格中的 client_ID 進(jìn)行打印/電子郵件等:警號(hào)：?jiǎn)螕舸税粹o時(shí)如何獲取$client['clientID']到make_invoice.php ？<tr><th>Create invoice </th><td><form action='make_invoice.php' method="POST">    <input type="submit" name="aanmaken" value="Click here">    </form></td></tr>
