本文实例讲述了Yii2实现ajax上传图片插件用法。分享给大家供大家参考,具体如下:
这里需要先下载 mdmsoft/yii2-upload-file.插件。
代码如下:
public function actionCreate() { $model = new DynamicModel([ \'nama\', \'file_id\' ]); // behavior untuk upload file $model->attachBehavior(\'upload\', [ \'class\' => \'mdm\\upload\\UploadBehavior\', \'attribute\' => \'file\', \'savedAttribute\' => \'file_id\' // coresponding with $model->file_id ]); // rule untuk model $model->addRule(\'nama\', \'string\') ->addRule(\'file\', \'file\', [\'extensions\' => \'jpg\']); if ($model->load(Yii::$app->request->post()) && $model->validate()) { if ($model->saveUploadedFile() !== false) { Yii::$app->session->setFlash(\'success\', \'Upload Sukses\'); } } return $this->render(\'upload\',[\'model\' => $model]); }
Then in view upload.php
<?php use yii\\helpers\\Html; use yii\\widgets\\ActiveForm; /* @var $this yii\\web\\View */ ?> <div> <?php $form = ActiveForm::begin([ \'options\' => [ \'enctype\' => \'multipart/form-data\'] ]); ?> <?= $form->field($model, \'nama\'); ?> <?= $form->field($model, \'file\')->fileInput(); ?> <?php if ($model->file_id): ?> <div class="form-group"> <?= Html::img([\'/file\', \'id\' => $model->file_id]) ?> </div> <?php endif; ?> <div class="form-group"> <?= Html::submitButton(\'Submit\', [\'class\' => \'btn btn-primary\']) ?> </div> <?php ActiveForm::end(); ?> </div>
