I'm coding a multiple upload function for my website. The upload was successful. But it's only save the first value to my database. Example i upload 3 files name 1.jpg, 2.jpg, 3.jpg. Then it will upload the 3 files successfully but save only the 1.jpg's name to database.
My controllers
public function actionCreate()
{
$model = new Resource3d();
if ($model->load(Yii::$app->request->post())) {
$model->files = UploadedFile::getInstances($model, 'files');
foreach ($model->files as $files){
$files->saveAs('uploads/resource3d/' . $files->baseName . $files->extension);
$model->path = '../web/uploads/resource3d/'. $files->baseName . $files->extension;
$model->name = $files->baseName;
$model->save();
}
return $this->redirect(['index']);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
My models:
public $files;
public function rules()
{
return [
[['name', 'path'], 'string', 'max' => 255],
[['files'], 'file', 'skipOnEmpty' => false, 'maxFiles' => 0],
];
}
Please help.
Thank you.
You are creating single object of your model Resource3d. You need to create multiple object if you want to save multiple records.
Try this :
public function actionCreate()
{
$model = new Resource3d();
if ($model->load(Yii::$app->request->post())) {
$model->files = UploadedFile::getInstances($model, 'files');
foreach ($model->files as $files){
$res_model = new Resource3d();
$res_model->load(Yii::$app->request->post());
$files->saveAs('uploads/resource3d/' . $files->baseName . $files->extension);
$res_model->path = '../web/uploads/resource3d/'. $files->baseName . $files->extension;
$res_model->name = $files->baseName;
$res_model->save();
}
return $this->redirect(['index']);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
This is just an example, change it according to your need.

I am trying to add captcha validation based on scenario, for which I am first retrieving number of failed attempts from database. For which I am using checkattempts() function. Based on the result I am displaying captcha in view and adding scenario condition in controller as below.
In LoginForm model:
public function rules()
{
return [
[['username', 'password'], 'required', 'on'=>'loginpage'],
[['username', 'password'], 'required', 'on'=>'withCaptcha'],
[['reference_url'], 'safe'],
[['verifyCode'], 'captcha', 'skipOnEmpty' => true,'on'=>'withCaptcha'],
['username','email', 'on'=>'loginpage', 'message'=> 'Please enter a valid email address'],
['password', 'validatePassword', 'on'=>'loginpage'],
['password', 'validatePassword', 'on'=>'withCaptcha'],
];
}
public function checkattempts($uname)
{
$user = \frontend\models\User::findByEmail($uname);
$ip = $this->get_client_ip();
if($user){
$data = (new Query())->select('*')
->from('login_attempts')
->where(['ip' => $ip])->andWhere(['user_ref_id' => $user->id])
->one();
if($data["attempts"] >=3){
return true;
}else{
return false;
}
}
return false;
}
in SiteController.php controller
public function actionLogin() {
if (!\Yii::$app->user->isGuest) {
return $this->redirect(Yii::$app->getUrlManager()->getBaseUrl() . '/../../');
}
$model = new \common\models\LoginForm();
$model->scenario = 'loginpage';
$captcha = false;
if(Yii::$app->request->post()){
$post_variables =Yii::$app->request->post('LoginForm');
if ($model->checkattempts($post_variables['username'])) {
$model->scenario = 'withCaptcha';
$captcha = true;
}
}
if ($model->load(Yii::$app->request->post()) && $model->validate()) {
$model->login(); print_r($model->getErrors()); exit;
} else {
return $this->render('login', [
'model' => $model, 'captcha' => $captcha,
]);
}
In my login.php view:
<?php if($captcha) { ?>
<?= $form->field($model, 'verifyCode')->widget(Captcha::className(),
['template' => '<div class="captcha_img">{image}</div>'
. '<a class="refreshcaptcha" href="#">'
. Html::img('/images/imageName.png',[]).'</a>'
. 'Verification Code{input}',
])->label(FALSE); ?>
<?php } ?>
In my controller when I am tring to print model errors at $model->login() function it is giving below error everytime even though the verification code is correct.
Array ( [verifycode] => Array ( [0] => The verification code is incorrect. ) )
Why is it failing every time. Is there any mistake in the code written?
Thanks in advance
I have a yii2 project, I am developing on my windows localhost and hosting remotely on linux.
Locally (windows) every thing is perfect.
While on linux, I have $model->id = null after $nodel->save(), although data is saved.
public function actionCreate() {
$model = new AppBreakingNews();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
I have tried die($model->id) after the save, it printed null.
Moreover, when I click on the update icon in the grid view, I am facing the same problem.
The AppBreakingNews is as follows:
<?php
namespace app\models\appmodels;
use app\models\BreakingNews;
use yii\behaviors\TimestampBehavior;
class AppBreakingNews extends BreakingNews {
public function behaviors() {
return [
[
'class' => TimestampBehavior::className(),
'createdAtAttribute' => 'created_at',
'updatedAtAttribute' => 'updated_at',
'value' => date('Y-m-d H:i:s'),
],
];
}
}
Notice that appBreakingNews extends the model BreakingNews that is generated by yii2 without any change.
Thanks in advance..
Please try to save model->save(false); because i think it validate something from model file.
public function actionCreate() {
$model = new AppBreakingNews();
if ($model->load(Yii::$app->request->post()) && $model->save(false)) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
or can you please print your model file here.
I'm very new with YII2. I want to create a download function to the file that was uploaded before. I've referred how to create action download at Gridview in Yii2. However, when I click button download, it load the blank page. Here the code.
At gridview
<?=GridView::widget([
'dataProvider'=>$dataProvider,
'id'=>'mygrid',
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'project_name',
'project_file',
'created_date',
[
'class' => 'yii\grid\ActionColumn',
],
['attribute'=>'Download',
'format'=>'raw',
'value' => function($data)
{
return
Html::a('Download file', ['firstyear/download', 'id' => $data->id],['class' => 'btn btn-primary']);
}
],
]
]);
?>
At actionDownload
public function actionDownload($id)
{
$download = Firstyear::findOne($id);
$path=Yii::getAlias('#webroot').'/uploads/'.$download->project_file;
if (file_exists($path)) {
return Yii::$app->response->sendFile($path);
}
}
At actionCreate (upload file)
public function actionCreate()
{
$model = new Firstyear();
if ($model->load(Yii::$app->request->post()))
{
$project =$model->project_name;
$model->file= UploadedFile::getInstance($model,'file');
$model-> file->saveAs('uploads/'.$project.'.'.$model->file->extension);
$model->project_file='uploads/'.$project.'.'.$model->file->extension;
$model->save();
Yii::$app->getSession()->setFlash('success','Data saved!');
return $this->redirect(['view','id'=> $model->id]);
}
else {
return $this ->renderAjax('create', [
'model'=>$model,
]);
}
}
Thanks.
I suspect that the $path is not correct, in the action create, you already include the uploads folder in your $model->project_file
public function actionCreate()
{
$model = new Firstyear();
if ($model->load(Yii::$app->request->post()))
{
.......
$model->project_file='uploads/'.$project.'.'.$model->file->extension;
$model->save();
....
}
}
but you use it again in actionDownlaod
public function actionDownload($id)
{
.....
$path=Yii::getAlias('#webroot').'/uploads/'.$download->project_file;
if (file_exists($path)) {
return Yii::$app->response->sendFile($path);
}
}
you should try to remove the uploads folder in the actionDownlaod, and added some debug message
public function actionDownload($id)
{
.....
$path=Yii::getAlias('#webroot').'/'.$download->project_file;
if (file_exists($path)) {
return Yii::$app->response->sendFile($path);
} else {
throw new NotFoundHttpException("can't find {$download->project_file} file");
}
}
I got this method that's intended to upload a file, but sometimes it does so when $this->imageFile is not instantiated. I have no idea why.
public function upload()
{
$path = Url::to('#webroot/images/photos/');
$filename = strtolower($this->username) . '.jpg';
$this->imageFile->saveAs($path . $filename);
return true;
}
I call the method upload() in beforeSave() like this:
public function beforeSave($insert)
{
if(parent::beforeSave($insert)){
if($this->isNewRecord)
{
$this->password = Yii::$app->security->generatePasswordHash($this->password);
}
$this->upload();
return true;
}
else
{
return false;
}
}
I called this method like 100 times with mixed results. I have no idea why this method call doesn't give the same result. It should either never work or always work, but for some reason the code is not deterministic at all.
public function actionCreate()
{
$model = new Member();
$model->imageFile = UploadedFile::getInstance($model, 'imageFile');
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
Another thing, when I use this code, I get a file, but the username is blank so I get a .jpeg file without a name.
public function actionCreate()
{
$model = new Member();
$model->imageFile = UploadedFile::getInstance($model, 'imageFile');
$model->upload();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
<?php
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
In the If clause you are redirecting to view and $model disappears between requests naturally. But in else you sending $model to view directly. It looks like the buggy section.
The other one, when you move the $model->upload() to actionCreate, you are placing it before If statement but you are loading the post to the model in if clause so, naturally user wasn't loading when you are trying to upload.
If you are prefer to send $model->upload() to action just be sure to call following method before upload. $model->load(Yii::$app->request->post())
I am very new to web development.
I'm newbie in here, my first question in stackoverflow..
i am confused what error on code, Code will be store data array csv to a database,
sorry my bad english.
Controller
public function actionUpload()
{
$model = new Skt();
//error_reporting(E_ALL);
//ini_set('display_error', 1);
if ($model->load(Yii::$app->request->post())) {
$file = UploadedFile::getInstance($model, 'file');
$filename = 'Data.' . $file->extension;
$upload = $file->saveAs('uploads/' . $filename);
if ($upload) {
define('CSV_PATH', 'uploads/');
$csv_file = CSV_PATH . $filename;
$filecsv = file($csv_file);
foreach ($filecsv as $data) {
$modelnew = new Skt();
$hasil = explode(",", $data);
$no_surat= $hasil[0];
$posisi= $hasil[1];
$nama= $hasil[2];
$tgl_permanen= $hasil[3];
$grade= $hasil[4];
$tgl_surat= $hasil[5];
$from_date = $hasil[6];
$to_date = $hasil[7];
$modelnew->no_surat = $no_surat;

$modelnew->nama = $nama;
$modelnew->tgl_permanen = $tgl_permanen;

$modelnew->save();
//print_r($modelnew->validate());exit;
}
unlink('uploads/'.$filename);
return $this->redirect(['site/index']);
}
}else{
return $this->render('upload',['model'=>$model]);
}
return $this->redirect(['upload']);
}
Model
class Skt extends \yii\db\ActiveRecord

return 'skt';
}
public $file;
public function rules()

];
}
}
thanks for helping..
change your code to the following to output the errors which could happen when you try to save. Errors could occur depending on your model rules.
if (!$modelnew->save()) {
var_dump($modelnew->getErrors());
}
getErrors() from Api
A better approach is to use exceptions to throw and catch errors on your import. Depends if you want to skip csv lines on errors or not.
finally it working with change this $hasil = explode(";", $data);
