出于学习目的，我正在oop php中针对属性/广告开发cms。我正在尝试上传通过具有特定属性的数据透视表连接的多张照片，但是我无法插入这些照片。当我插入包含两张或更多张照片的属性时，我需要这些照片在数据透视表中具有不同的ID，但属性具有相同的ID。当时我成功拍摄了一张照片，但是拍摄了多张却出现了错误：
警告：explode（）期望参数2为字符串，数组形式为 当我var dump $ tmp时，在第177行的C：\ xampp \ htdocs \ App \ Models \ Ad.php 变量，我得到null和
警告：end（）期望参数1为数组，在中为null var dump时，第179行的C：\ xampp \ htdocs \ App \ Models \ Ad.php $ file_ext变量我得到空字符串
我正在使用三个表来做到这一点。照片（名称，扩展名，created_at，updated_at），property_photo（property_id，photo_id），属性（标题，描述，type_of_property，use_of_the_property，正交，位置...）。这是我的代码：
Ad Model:
public function createAd($data, $pht)
{
if (isset($data['photoExtension'])) {
$this->photoExtension = preg_replace('~(?<=a)\w~', "", $data['photoExtension']);
}
$this->photoExtension = strtolower(strrchr( $pht, '.' ));
$this->db->query("INSERT INTO properties (title, description, type_of_property, use_of_the_property, quadrature, location, price, sales_clerk_info, booked, type_of_market, type_of_payment, status) VALUES (:title, :description, :type_of_property, :use_of_the_property, :quadrature, :location, :price, :sales_clerk_info, :booked, :type_of_market, :type_of_payment, :status) ");

$this->db->execute();

看看用于插入多个文件的$ _FILES数组格式。 This answer和this的php文档页面将对您有用。
您期望在photoValidate（）$ file ['name']中输入字符串，但是有一个数组，所以出现错误。
最好和最简单的方法是使用symfony http-foundation component之类的东西。
控制器：
public function createAction()
{
$request = Request::createFromGlobals();
//...
$photo_validate = $this->AdModel->photoValidate($request->files->get('photo'));
//...
}
此外，这种验证非常混乱。您也可以使用symfony validator component。
