yii2多文件上传接口开发（特色，拥有时间目录，数据能保存到数据库中,postman测试,）

如果你想到调通接口，请看我的文章。看完我的调通接口文章后，请在api/web/下新建一个uploads目录

postman：

gii:生成model:一次能上传10个文件

<?php

namespace common\models;

use Yii;

/**
 * This is the model class for table "upmore".
 *
 * @property integer $id
 * @property string $name
 * @property string $path
 * @property string $time
 */
class Upmore extends \yii\db\ActiveRecord
{public $file;
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'upmore';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['file'], 'file', 'maxFiles' => 10,'extensions'=>'jpg,png,gif,txt,doc'],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'id' => 'ID',
            'name' => 'Name',
            'path' => 'Path',
            'time' => 'Time',
        ];
    }
}

<?php

use yii\base\Model;

        if (Yii::$app->request->isPost) {
            $file = UploadedFile::getInstances($model, 'file');
            $path='uploads/'.date("YmdH",time()).'/';
            if ($file && $model->validate()) {
                if(!file_exists($path)){
                    mkdir($path,0775,true);
                }
                foreach ($file as $fl) {
                    $fl->saveAs($path . $fl->baseName. '.' . $fl->extension);
                    Yii::$app->db->createCommand()->insert('upmore', [
                        'path'=>"/".$path.$fl->baseName. '.' . $fl->extension,
                    'name' =>$fl->baseName. '.' . $fl->extension,
                    'time'=>date('Y-m-d H:i:s')
                ])->execute();
                }
               

            }
