【问题描述】:
我尝试在后端上传文件,每次上传文件都成功上传并成功保存在数据库中,但它没有保存到我指定的目录,所以我的应用程序找不到文件,我已经为 web 目录中的上传文件夹授予 777 权限。以下是我的代码
模型处理和保存文件上传...
yii2高级模板如何上传根目录下的文件?
负责上传的模型
<?php
namespace backend\models;
use yii\base\Model;
use yii\web\UploadedFile;
use yii\Validators\FileValidator;
class UploadForm extends Model {
public $img;
public $randomCharacter;
public function rules(){
return[
[['img'], 'file', 'skipOnEmpty' => false, 'extensions'=> 'png, jpg,jpeg'],
];
}
public function upload(){
$path = '/uploads/';
$randomString = '';
$length = 10;
$character = "QWERTYUIOPLKJHGFDSAZXCVBNMlkjhgfdsaqwertpoiuyzxcvbnm1098723456";
$randomString = substr(str_shuffle($character),0,$length);
$this->randomCharacter = $randomString;
if ($this->validate()){
$this->img->saveAs($path .$randomString .'.'.$this->img->extension);
return true;
}else{
return false;
}
}
}
负责将信息保存到数据库的产品型号
<?php
namespace backend\models;
use Yii;
use yii\base\Model;
use yii\web\UploadedFile;
use yii\Validators\FileValidator;
class Products extends \yii\db\ActiveRecord
{
public static function tableName()
{
return 'products';
}
public function rules()
{
return [
[['name'], 'string', 'max' => 100],
[['descr', 'img', 'reviews'], 'string', 'max' => 255],
// [['file'], 'file', 'skipOnEmpty' => false, 'extensions'=> 'png, jpg,jpeg']
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'img' => 'Img',
];
}
}
my controller and the action
public function actionCreate()
{
$time = time();
$model = new Products();
$upload = new UploadForm();
if ($model->load(Yii::$app->request->post()) ) {
//get instance of the uploaded file
$model->img = UploadedFile::getInstance($model, 'img');
//define the file path
$upload->upload();
//save the path in the db
$model->img = 'uploads/' .$upload->randomCharacter .'.'.$model->img->extension;
$model->addtime = $time;
$model->save();
return $this->redirect(['view', 'product_id' => $model->product_id]);
}else {
return $this->render('create', [
'model' => $model,
]);
}
}
and my view file has been modified too thanks for any help
