删除客户端时，除了存储在文件夹/ view / cliente / imagenes中的图像之外，其所有信息都将被删除

Eliminar方法获取id，删除客户端但不删除与该客户端关联的/ view / cliente / imagenes文件夹中的jpg文件。
创建客户端时，必须加载图像，只将图像名称存储在数据库中，图像存储在文件夹/ view / client / images中
客户数据库
CREATE TABLE cliente (
id int(11) NOT NULL,
dni int(60) NOT NULL,
Nombre varchar(50) NOT NULL DEFAULT '0',
Apellido varchar(50) NOT NULL DEFAULT '0',
Correo varchar(50) NOT NULL,
Telefono varchar(60) NOT NULL,
Imagen text COLLATE utf8_spanish_ci NOT NULL
);
ALTER TABLE cliente ADD PRIMARY KEY (`id`);
ALTER TABLE cliente MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;
我不知道保存图像的方式是什么，但它应该是这样的：
public function Eliminar($id)
{
try {
// Get image path
$imgPath = $this->model->Obtener($id)['Imagen'];
// Delete image from server
unlink($imgPath);
$stm = $this->pdo->prepare("DELETE FROM cliente WHERE id = ?");
$stm->execute(array($id));
} catch (Exception $e)
{
die($e->getMessage());
}
}
