UploadedFile是Yii2自带的文件上传工具。 下面是在控制器里写的一个文件上传,作为笔记,还有待完善,要加文件类型验证、多文件上传等,而且还放到了Cotroller里了,应该放到Model里。 /** * 上传图片 */ public function actionUpload() { Yii::$app->response->format = Response::FORMAT_JSON; if(Yii::$app->...
我们先来看看在yii2中支持的图片上传怎么进行处理的。 首先我们创建model\Upload.php文件 <?php namespace backend\models; use Yii; use yii\web\UploadedFile; class Upload extends \yii\db\ActiveRecord { /** * @var UploadedFile|Null file attribute */ public $file; /** * @return array the ...
源码https://github.com/yiichina/yii2/blob/api/framework/web/UploadedFile.php UploadedFile represents the information for an uploaded file. You can callgetInstance()to retrieve the instance of an uploaded file, and then usesaveAs()to save it on the server. You may also query other information...

1，是否通过http协议上传。2，form中是否有enctype="multipart/form-data"。3，上传文件是否超出了规定的大小。4，存放上传文件的文件夹是否存在,上传的文件夹是否具有写权限。5，上传文件应该是使用move_uploaded_file()这个函数吧！6，请确保$_FILES["upload"]['error']=0;如果这几个都没问题，...
因为文件里没有定义 move_uploaded_file 这个函数。 你如果定义了这个函数，就不会出错了。在文件最后添加 function move_uploaded_file($filename, $filePath) { //在服务器上写入文件 } 就不会出错了。然后在函数中实现文件上传就行了。
