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'm still beginner in yii and php.
my problem is:
i want add a value that from db to my textfield.
my db table 'config' have 3 column, id;name;value;
i have tried code like this:
<?= $form->field($model, 'name')->textInput(['value'=>$model->value])->label('name',['class'=>'label-class'])?>
but it didn't show the value.
i want a update form for change value . example: name: title; value: hello world.
Your controller should be something like that:
public function actionUpdate($id)
{
$model = $this->findModel($id);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
protected function findModel($id)
{
if (($model = Mymodel::findOne($id)) !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
and in view you simply write
<?= $form->field($model, 'name')->textInput()->label('name',['class'=>'label-class'])?>
Your database values will be in your field.
For simple CRUD you may use GII http://www.yiiframework.com/doc-2.0/guide-start-gii.html
I'm doing a form where I enter the data in two models in a single form. My question is how to record data entry in actionCreate () and call these models in a single form.
These are my inscritoController.php
public function actionCreate()
{
$model = new Inscrito();
$modelEmpresa = new Empresa();
if ($model->load(Yii::$app->request->post()) && $model->load(Yii::$app->request->post()) && $modelEmpresa->save() && $modelEmpresa->save())
{
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
'modelEmpresa' => $modelEmpresa,
]);
}
}
And Error:
PHP Notice – yii\base\ErrorException
Undefined variable: modelEmpresa
add this line in your controller
use app\models\Empresa;
Load Yii::$app->request->post() to $modelEmpresa and confirm model call in your controller use app\models\Empresa;
public function actionCreate()
{
$model = new Inscrito();
$modelEmpresa = new Empresa();
if ($model->load(Yii::$app->request->post()) && $modelEmpresa->load(Yii::$app->request->post()) && $model->save() && $modelEmpresa->save())
{
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
'modelEmpresa' => $modelEmpresa,
]);
}
}
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())
Getting error when I am trying to create dynamic form in using yii2-dynamicform. at the time of create method it is working fine but at the time of update showing the error. I have two tables one is
1.vendors &
2.vendors_more_categories
Relation is 1-* between vendors & vendors_more_categories I just refereed https://github.com/wbraganca/yii2-dynamicform this link.

You accessing modelsVendorsMoreCategories[0] (as an element of an array )
'model'=> $modelsVendorsMoreCategories[0],
in your DinamicForm widget but when you update the model you pass as $modelsVendorsMoreCategories this value
$modelsVendorsMoreCategories = $model->ven_id;
(don't seems an array, you must be sure this object contain an array with a proper element in 0 index))
'modelsVendorsMoreCategories' => (empty($modelsVendorsMoreCategories)) ?
[new VendorsMoreCategories] : $modelsVendorsMoreCategories
]);
$modelsVendorsMoreCategories should contain the VendorsMoreCategories model in actionUpdate method. In this code ($modelsVendorsMoreCategories = $model->ven_id) $modelsVendorsMoreCategories contains $model->ven_id. It is an integer value, not the VendorsMoreCategories object.
The Vendors model should contain a relation on the VendorsMoreCategories model:
class Vendors extends \yii\db\ActiveRecord
{
....
public function getVendorsMoreCategories()
{
return $this->hasMany(VendorsMoreCategories::className(), 'vendor_id'=>'id']);
}
}
And then, you should use that relation in your actionUpdate method:
$model = $this->findModel($id);
$modelsVendorsMoreCategories = $model->vendorsMoreCategories;
if(!$modelsVendorsMoreCategories) {
$modelsVendorsMoreCategories = [new VendorsMoreCategories];
}
In your actionUpdate you have:
$modelsVendorsMoreCategories = $model->ven_id;
But you should have:
$modelsVendorsMoreCategories = $model->nameOfMyRelation;
To get what's the real name, go in your $model, and look for something like:
/**
* #return \yii\db\ActiveQuery
*/
public function getNameOfMyRelation()
{
return $this->hasMany(VendorsMoreCategories::className(), ['ven_id' => 'id']);
}
If you don't have any function making the relation of this two tables, write one. If you having trouble doing that, you can always use the gii's model generator and check the Vendors model (you dont need to replace it, just preview the code).
Check your create.php file in view folder, pass required variable on
_form.php file from here as:-
<?= $this->render('_form', [
'model' => $model,
'modelsAddress' => $modelsAddress,
]) ?>
Check Your create file in view folder:
Controller:
Controller pass the parameter into create.php
return $this->render('create', [
'model' => $model,
'modelsVendorsMoreCategories' => (empty($modelsVendorsMoreCategories)) ? [new VendorsMoreCategories] : $modelsVendorsMoreCategories
]);
View:create.php
If You miss the parameter: 'modelsVendorsMoreCategories' =>$modelsVendorsMoreCategories.
It shows the Undefined variable error in _form.php page.
<?= $this->render('_form', [
'model' => $model,
'modelsVendorsMoreCategories' =>$modelsVendorsMoreCategories
])?>
View:_form.php
$modelsVendorsMoreCategories[0];
the paramater not passing before now it passing.
