从控制器创建函数:
$imageName = $model->primary_name;
// get the uploaded file instance. for multiple file uploads
$model->file = UploadedFile::getInstance($model, 'file');
$model->file->saveAs('uploads/'.$imageName.'.'.$model->file->extension);
//save the path in db
$model->id_image = 'uploads/'.$imageName.'.'.$model->file->extension;
$imageName1 = $model->adult_2_name;
// get the uploaded file instance. for multiple file uploads
$model->file2 = UploadedFile::getInstance($model, 'file2');
$model->file2->saveAs('uploads/adult_2/'.$imageName1.'.'.$model->file2->extension);
//save the path in db
$model->id_image_2 = 'uploads/adult_2/'.$imageName1.'.'.$model->file2->extension;
$model->save();
public $file;
public $file2;
[['file','file2'],'file'],
[['id_image', 'id_image_2'], 'string', 'max' => 500],

得到错误:在string
上调用成员函数savea ()
更新活动形式 ....................
这一行的变化:

]);
?>
应该与file2相关，否则你将覆盖第一个上传的文件:
<?= $form->field($model, 'file2')->fileInput(
