關於Yii2.0多檔案上傳的代碼

本文通過執行個體代碼給大家介紹了Yii2.0多檔案上傳執行個體說明，非常不錯，具有參考借鑒價值，需要的朋友參考下吧

建立控制器FormController

<?php namespace frontend\controllers;use Yii;use yii\web\Controller;use frontend\models\Uploadm;use yii\web\UploadedFile;class FormController extends Controller{  public function actionMyfiles(){      $model=new Uploadm();      return $this->renderPartial('myfiles',['model'=>$model]);  }  public function actionGetfiles(){    $model = new Uploadm();    if (Yii::$app->request->isPost) {      $model->imgFile = UploadedFile::getInstances($model, 'imgFile');      if ($model->upload()) {        // 檔案上傳成功        echo '上傳成功';      }    }  }

建立模型Uploadm.php

<?phpnamespace frontend\models;use Yii;use yii\base\Model;use yii\web\UploadedFile;class Uploadm extends Model{  public $imgFile;  public function rules(){    return [       [['imgFile'], 'file','maxFiles' => 5],//最多5張    ];  }  public function upload()  {   if ($this->validate()) {      foreach ($this->imgFile as $file) {       $file->saveAs('uploads/' . $file->baseName . '.' . $file->extension);     }     return true;   } else {     return false;   }  }}

建立視圖/views/form/myfiles.php

<?phpuse yii\helpers\Html;use yii\widgets\ActiveForm;$form = ActiveForm::begin([  'id' => 'login-form',  'options' => ['class' => 'form-horizontal','enctype' => 'multipart/form-data'],  'action'=>'?r=form/getfiles',  'method'=>'post']) ?>  <?= $form->field($model, 'imgFile[]')->fileInput(['multiple' => true]) ?>  <p class="form-group">    <p class="col-lg-offset-1 col-lg-11">      <?= Html::submitButton('上傳', ['class' => 'btn btn-primary']) ?>    </p>  </p><?php ActiveForm::end() ?>
