如何解决yii2中多个文件上传的api
嘿，我是yii2的初学者，当我的请求只给我1个文件数组而不是多个文件数组时，我就在yii2中学习如何创建api
下面是我的模型文件
<?php
namespace common\models;
use Yii;
/**
* This is the model class for table "question_attachment".
*
* @property int $id
* @property int $question_id
* @property string $attachment
*/
class QuestionAttachment extends \yii\db\ActiveRecord
{
/**
* {@inheritdoc}
*/
public static function tableName()
{
return 'question_attachment';
}
/**
* {@inheritdoc}
*/
public function rules()
{
return [
[['attachment'],'required'],[['question_id'],'integer'],//[['attachment'],'string','max' => 255],[['attachment'],'file','maxFiles' => 10,'skipOnEmpty' => true,'extensions' => 'png,jpge,jpg,pdf,mp4','mimeTypes' => 'image/jpeg,image/png,image/jpe'],];
}
/**
* {@inheritdoc}
*/
public function attributeLabels()
{
return [
'id' => 'ID','question_id' => 'Question ID','attachment' => 'Attachment',];
}
public function getQuestions(){
return $this->hasOne(Question::className(),['id' => 'id']);
}
}
下面的代码是我要上传多张图片的动作
public function actionMultiple($params=['attributes'=>[
['name'=>'QuestionAttachment[attachment]','type'=>'file','description'=>'']],'auth'=>0,'method'=>'POST'])
{
$model = new QuestionAttachment();
$model->question_id = '1';
if (Yii::$app->request->isPost) {
$model->attachment = UploadedFile::getInstances($model,'attachment');
if(!$model->attachment){
return array('status'=>false,'message'=>'Please select a photo.');
}
if ($model->attachment && $model->validate()) {
foreach ($model->attachment as $file) {
$file->saveAs(Yii::$app->basePath.'/../img_assets/questions/' . $file->baseName . '.' . $file->extension);
}
}
}print_r($model);die();
return array('status' => true,'message' => 'Error');
}
这就是我对此操作代码的回应

当我上传了两张图片，但是数组仅显示了我弄乱了一张图片吗？
解决方法
所以最后我得到了答案，我的foreach返回语句没有保存多个数据，所以这里是最终代码
public function actionMultiple(){
$model = new Media;
$model->post_id = '2';
if (Yii::$app->request->ispost) {
$model->media = UploadedFile::getInstances($model,'media');
if ($model->media) {
foreach ($model->media as $value) {
$model = new Media;
$model->post_id = '2';
$BasePath = Yii::$app->basePath.'/../images/post_images';
$filename = time().'-'.$value->baseName.'.'.$value->extension;
$model->media = $filename;
if ($model->save()) {
$value->saveAs($BasePath.$filename);
}
}
return array('status' => true,'message' => 'Image Saved');
}
}
return array('status' => true,'data' => $model);
}
