查看:
<?php echo FileInput::widget([
'model' => $visaDocument,
'attribute' => 'temp_image[]',
'options' => ['multiple' => true]
]); ?&GT;
型号:
定义一个变量:
public $temp_image;
在规则中:
[['temp_image'], 'file','extensions' => ' pdf, docx, odt, jpg, png','maxFiles' => 4],
创建了一个函数:
public function upload($model, $id) {
$imageCount = SbhrmVisaDocument::find()->where(['visa_document_id' => $id])->count();
foreach ($model->temp_image as $file) {
if($imageCount < 4){
$image = new SbhrmVisaDocument();
$image->save();
$file->saveAs(\Yii::$app->BasePath . '/uploads/' . $file->name);
$image->visa_document_name = $file->name;
$image->emp_id = $id;
$image->save();
}
++$imageCount;
}
return true;
}
控制器:
$visaDocument->temp_image = UploadedFile::getInstances($visaDocument, 'temp_image');
if(!empty($visaDocument->temp_image)){
if (!$model->upload($visaDocument,$model->emp_id)) {
return;
}
if($model->validate()){
$model->save();
//$this->afterSaveSetting($model);
Yii::$app->session->setFlash('success','Request Submitted');
return $this->redirect(\yii\helpers\Url::to(['visa-initiation/my-list']));
}
}
但是,当我尝试上传多个文件时,只保存了最后一个选定的文件。我只需按照演示http://demos.krajee.com/widget-details/fileinput。
答案 0 :(得分:0)
我认为你应该添加
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?>
可能会有所帮助。你已经包括了吗?
