I have a file Input field in my form which works good to upload the file. But I want to keep the provision for user that they might not upload any file at all.
My Code looks like below -
Model Rule -
[['jha'],'file','skipOnEmpty' => true,'extensions' => 'pdf'],
Form
<?= $form->field($model, 'jha')->fileInput(['accept' => 'application/pdf']); ?>
Controller -
public function actionCreatenewworkbasic()
{
$model = new Workpermit();
$model->wp_timeissued = date('Y-m-d H:i:s');
if ($model->load(Yii::$app->request->post()))
{
$timenow = date('-Y-m-d-H-i-s');
$model->jha = UploadedFile::getInstance($model,'jha');
$model->jha->saveAs('uploads/jha/'.$model->jha->baseName.$timenow.'.'.$model->jha->extension);
//save the path in the db
$model->wp_jhaattach = 'uploads/jha/'.$model->jha->baseName.$timenow.'.'.$model->jha->extension;
$model->jha = null;
$model->save(false);
return $this->redirect(['availablework']);
}else{
return $this->renderAjax('createnewworkbasic', [
'model' => $model,
]);
}
}
By this code, If I leave the upload field untouched, I get error -
Call to a member function saveAs() on null
Check empty before saveAs()
if ($model->load(Yii::$app->request->post())) {
$timenow = date('-Y-m-d-H-i-s');
$model->jha = UploadedFile::getInstance($model,'jha');
if (!empty($model->jha)) {
$model->jha->saveAs('uploads/jha/'.$model->jha->baseName.$timenow.'.'.$model->jha->extension);
//save the path in the db
$model->wp_jhaattach = 'uploads/jha/'.$model->jha->baseName.$timenow.'.'.$model->jha->extension;
}
$model->jha = null;
$model->save(false);
return $this->redirect(['availablework']);
}

I want to retrieve some data from 'tbl_karyawan' and input into 'tbl_absen' which is if the NIP exist from 'tbl_karyawan' then parshing some data into 'tbl_absen'. I was create the code, and the data is going well. but i have something trouble with
i want the data input in Nip_kyn be like 'KIP001' not [{"Nip_kyn":"KIP001"}].
this is my Model
public function presensi($data)
{
$isExist = DB::table('tbl_karyawan')
->where('Nip_kyn', $data)->exists();
if ($isExist) {
$namakyn = DB::table('tbl_karyawan')->where($data)->get('Nama_kyn');
$nippppp = DB::table('tbl_karyawan')->where($data)->select('Nip_kyn')->get($data);
$values = array('Nip_kyn' => $nippppp, 'Nama_kyn' => $namakyn, 'Jam_msk' => now(), 'Log_date' => today());
DB::table('tbl_absen')->insert($values);
} else {
echo 'data not available';
}
}
this is my controller
public function get()
{
$day = [
'time_in' => $this->AbsenModel->timeIN(),
'time_out' => $this->AbsenModel->timeOut(),
'break' => $this->AbsenModel->break(),
// absen here
's' => $this->AbsenModel->absensi(),
];
$data = [
'Nip_kyn' => Request()->Nip_kyn,
];
$this->AbsenModel->presensi($data);
return view('v_absen', $data, $day);
}
Yup, I finally got it, the problem is on my model.
$nama_karyawan = DB::table('tbl_karyawan')->where($data)->value('Nama_kyn');
$nipkyn = DB::table('tbl_karyawan')->where($data)->value('Nip_kyn');
I just change 'get' to 'value'.
I have a model with the following custom attributes topic_names, topic_details (string fields). I have also a model form with the custom attributes and custom rules. When I insert wrong data in the form fields, there is a model error, but it isn't displayed.
Model code:
......
public function rules()
{
return [
...
[['topics_names','topics_details'],'string'],
[['topics_names'],'checkCorrectAndSetTopics'],
];
}
public function checkCorrectAndSetTopics(){
if($this->topics_names AND $this->topics_details){
$topicsNamesArray = explode(',',$this->topics_names);
$topicsDetailsArray = explode(';',$this->topics_details);
if(sizeof($topicsNamesArray) !== sizeof($topicsDetailsArray)){
$this->addError('topics_names', \Yii::t('app', 'The topics names and details sets have different sizes'));
return FALSE;
}
}
return TRUE;
}
The problem is when the second rules is violeted, the form doesn't show any error, but there is. I checked it debugging the code below.
Form code:
..........
<?php
ActiveForm::$autoIdPrefix = createRandomId();//Function which creates a random id
$form = ActiveForm::begin(
['enableAjaxValidation' => true, "options"=> ["class"=>"extra-form"]]);
?>
<?= $form->errorSummary($model); ?>
<?= $form->field($model, 'topics_names')->textInput()
->label(\Yii::t('app', 'Topics Names'))?>
<?= $form->field($model, 'topics_details')->textarea(['rows' => 6])
->label(\Yii::t('app', 'Topics Details'))?>
........
Controller code:
public function actionAddExtraData($id){
if(!Yii::$app->request->isAjax){
throw new ForbiddenHttpException(\Yii::t('app','Cannot access this action directly.'));
}
$event = $this->findModel($id);
$extraData = ExtraData::find()
->andWhere(['event_id'=>$id])
->one();
if(!$extraData){
$extraData = new ExtraData();
$extraData->event_id = $id;
}else{
$extraData->prePerformForm();//Insert data on custom attributes
}
if(Yii::$app->request->isPost AND Yii::$app->request->isAjax AND Yii::$app->request->post("submitting") != TRUE
AND $extraData->load(Yii::$app->request->post())){
Yii::$app->response->format = Response::FORMAT_JSON;
$validation = ActiveForm::validate($extraData);
return $validation;
}
if ($extraData->load(Yii::$app->request->post()) && $extraData->save()) {
if (Yii::$app->request->isAjax) {
Yii::$app->response->format = Response::FORMAT_JSON;
return ["success" => TRUE];
} else {
return $this->redirect(Yii::$app->request->referrer);
}
}
return $this->renderAjax('_event_extra_form',['model'=>$extraData,'event'=>$event]);
}
First thing, pretty sure you don't need to return true or false, you just need to add error. Second thing, in your example you name the attribute, you can actually get this when defining the function, so your function could look something like this
public function checkCorrectAndSetTopics($attribute, $model){
if($this->topics_names AND $this->topics_details){
$topicsNamesArray = explode(',',$this->topics_names);
$topicsDetailsArray = explode(';',$this->topics_details);
if(sizeof($topicsNamesArray) !== sizeof($topicsDetailsArray)){
$this->addError($attribute, \Yii::t('app', 'The topics names and details sets have different sizes'));
}
}
}
I am new to cakephp.Below the number being bold is the time the data is being created and code to validate .My problem is to validate the data should between 8 hours not more that using Model. is there any wrong in my code?
sample data=L02A-180129-1215-A
The code to find the table based on data
public function sa01() {
$trv_no = $this->data[$this->alias]['TRV_No_01'];
$line_no = intval(substr($trv_no, 1, 2));
$table_name = 'Ticket_L' . $line_no;
$this->Ticket->setSource($table_name);
$this->Ticket->recursive =-1;
code for validation
Batch_time is a column name for the table
$time = $this->Ticket->find('all',array('conditions' => array('Ticket.Batch_Time >=' => date('Y-m-d H:i:s', strtotime('-8 hour')))));
if(empty($time))
{
$table_name = 'Ticket_L0';
$this->Ticket->setSource($table_name);
//$ticket = $this->Ticket->find('first', array('conditions' => array('Ticket.TRV_No' => $trv_no)));
$time = $this->Ticket->find('all',array('conditions' => array('Ticket.Batch_Time >=' => date('Y-m-d H:i:s', strtotime('-8 hour')))));
if(empty($time)) { return false; } else { return true; }
}
else
{ return true; }
}
So I am working with Yii2 and am fairly new to it. I am using Kartik File upload and have attempted to convert the code for multiple files. but it only saves the first file.
I have removed the validation as this was also failing but will add back in once I know all else is working.
Model:
/**
* Process upload of image
*
* #return mixed the uploaded image instance
*/
public function uploadImage() {
// get the uploaded file instance. for multiple file uploads
// the following data will return an array (you may need to use
// getInstances method)
$image = UploadedFile::getInstances($this, 'image');
foreach ($image as $images) {
// if no image was uploaded abort the upload
if (empty($images)) {
return false;
}
// store the source file name
$this->image_src_filename = $images->name;
$extvar = (explode(".", $images->name));
$ext = end($extvar);
// generate a unique file name
$this->image_web_filename = Yii::$app->security->generateRandomString().".{$ext}";
// the uploaded image instance
return $images;
} }
Controller:
/**
* Creates a new PhotoPhotos model.
* If creation is successful, the browser will be redirected to the 'view' page.
* #return mixed
*/
public function actionCreate()
{
$model = new PhotoPhotos();
if ($model->load(Yii::$app->request->post())) {
// process uploaded image file instance
$images = $model->uploadImage();
if ($model->save(false)) {
// upload only if valid uploaded file instance found
if ($images !== false) {
$path = $model->getImageFile();
$images->saveAs($path);
}
return $this->redirect(['view', 'id' => $model->ID]);
} else {
//error in saving
}
}
return $this->render('create', [
'model' => $model,
]);
}
View:
//uncomment for multiple file upload
echo $form->field($model, 'image[]')->widget(FileInput::classname(), [
'options'=>['accept'=>'image/*', 'multiple'=>true],
]);
I see one problem which is that you reversed $images and $image in
foreach ($image as $images)
which should be
foreach ($images as $image)
Cheers
I have yii2 application using advanced template and database mySql, i already make function for import an excel file to one of the table,
I made the function in a controller named student that contains CRUD of students data.this is my code
public function actionImportExcel()
{
$inputFile = 'uploads/siswa_file.xlsx';
try{
$inputFileType = \PHPExcel_IOFactory::identify($inputFile);
$objReader = \PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFile);
} catch (Exception $e) {
die('Error');
}
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
for($row=1; $row <= $highestRow; $row++)
{
$rowData = $sheet->rangeToArray('A'.$row.':'.$highestColumn.$row,NULL,TRUE,FALSE);
if($row==1)
{
continue;
}
$siswa = new Siswa();
$siswa->nis = $rowData[0][0];

$siswa->kelas = $rowData[0][11];
$siswa->save();
print_r($siswa->getErrors());
}
die('okay');
}
but i don't know how to make a button in a view to make this function work. i mean i want to make a button that when the user click the button and browse their excel file they can import that file and the data inside the excel can import to database
First you should upload the file
and then processing with your function
there are several parts of code you must produce ..
eg a view for the user to upload the file
View: #app/views/site/upload.php
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]) ?>
<?= $form->errorSummary($model); ?>
<?= $form->field($model, 'imageFile')->fileInput() ?>
<button>Submit</button>
<?php ActiveForm::end() ?>
Controller: #app/controllers/SiteController.php
namespace app\controllers;
use Yii;
use yii\web\Controller;
use app\models\UploadForm;
use yii\web\UploadedFile;
class SiteController extends Controller
{
public function actionUpload()
{
$model = new UploadForm();
if (Yii::$app->request->isPost) {
$model->imageFile = UploadedFile::getInstance($model, 'imageFile');
if ($model->upload()) {
// file is uploaded successfully
return;
}
}
return $this->render('upload', ['model' => $model]);
}
}
Model: #app/models/UploadForm.php
namespace app\models;
use yii\base\Model;
use yii\web\UploadedFile;
class UploadForm extends Model
{
/**
* #var UploadedFile
*/
public $imageFile;
public function rules()
{
return [
[['imageFile'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg'],
];
}
public function upload()
{
if ($this->validate()) {
$this->imageFile->saveAs('uploads/' . $this->imageFile->baseName . '.' . $this->imageFile->extension);
return true;
} else {
return false;
}
}
}
the code is from this doc
