Question

我尝试删除数据....但它捕获了此错误....当我尝试使用mvc样式对php进行新操作时....当我尝试使用printR ist返回字符串而不是整数进行调试时....

未捕获的PDOException：SQLSTATE [22P02]：无效的文本表示形式：7 错误：整数：“ Compliance”中的输入语法无效 C：\ xampp \ htdocs \ ims \ app \ models \ CMP999 \ CMP999.php：119堆栈跟踪：＃0 C：\ xampp \ htdocs \ ims \ app \ models \ CMP999 \ CMP999.php（119）： PDOStatement-> execute（）＃1 C：\ xampp \ htdocs \ ims \ app \ controllers \ Compliance \ CMP999Controller.php（150）： CMP999-> deleteData（'Compliance'）＃2 C：\ xampp \ htdocs \ ims \ app \ core \ App.php（146）： CMP999Controller-> delete（'Compliance'，'CMP999'，'delete'，'1'）＃3 C：\ xampp \ htdocs \ ims \ public \ index.php（7）：App-> __ construct（）＃4 {main} 在第119行的C：\ xampp \ htdocs \ ims \ app \ models \ CMP999 \ CMP999.php中抛出

// CMP999.php模型

public function deleteData($stud_id) {

    // $sql = "DELETE FROM test WHERE id = :id";
    //$stmt = $this->pdo->prepare($sql);
    //$stmt->execute([':id' => $id]);

    $count2 = $this->pdo->prepare("DELETE FROM test WHERE stud_id=:stud_id");
    $count2->bindParam("stud_id", $stud_id);
    $count2->execute();

    return $count2;


}

// CMP999Controller.php

public function delete($stud_id) {


     // print_r($stud_id);



    //die();



    if ($this->model('CMP999')->deleteData($stud_id)) {





        header('Location: ' . BASE_URL . 'Compliance/CMP999');

        exit();
    }
}

// index.php，点击删除按钮

<a href="<?= BASE_URL; ?>Compliance/CMP999/delete/<?= $column['stud_id']; ?>" class="btn btn-danger float-right ml-3" onclick=" return confirm('Are you Sure?');" ><img src="<?= BASE_URL ?>images/pemadam.png" alt="STALIN" width="20"> </a>

我希望我可以在单击按钮时删除数据...

我的ID返回字符串是“ Compliance”
