本人搜索了很多关于yii2利用自带UploadedFile实现上传图片介绍,下面我来记录一下。

创建一个 models/UploadForm.php:

namespace app\models;use yii\base\Model;use yii\web\UploadedFile;/*** UploadForm is the model behind the upload form.*/class UploadForm extends Model{ /** * @var UploadedFile file attribute */ public $file; /** * @return array the validation rules. */ public function rules() { return [ [['file'], ‘file'], ]; }}

视图文件

<?phpuse yii\widgets\ActiveForm;?><?php $form = ActiveForm::begin([‘options' => ['enctype' => 'multipart/form-data']]) ?><?= $form->field($model, ‘file')->fileInput() ?><button>Submit</button><?php ActiveForm::end() ?>

控制器

use app\models\UploadForm;use yii\web\UploadedFile;public function actionUpload(){ $model = new UploadForm(); if (Yii::$app->request->isPost) { $model->file = UploadedFile::getInstance($model, ‘file'); if ($model->file && $model->validate()) { $model->file->saveAs(‘uploads/' . $model->file->baseName . ‘.' . $model->file->extension); } } return $this->render(‘upload', ['model' => $model]);}
