Multiple nested widget example
It's possible to send me any example of deeper scenario with mutiple nested widget?
"Here's could be hypothetical scenario: A PERSON can have many HOUSES, each house, can have multiple ROOMS."
Thank you.
+1 My problem is when pressing add for the second level widget it add the first within. How can i separate forms. ?
Try to use different values for 'widgetBody' parameter in parent and child widgets Also, take unique values for 'insertButton' and 'deleteButton' for each child widget (i use foreach index)
I don't think its supported in that manner. Otherwise we would know by now. I hope I'm wrong though :)
Yes, is it possible @skeeran. I apologize for still have not added in the documentation an example of how to do this. I'll try to work on it this week.
'dynamic-form']); ?>
is it possible to have multitple "dynamic-form" in the same view
I am also interested if I can have more dynamic forms in the same form.. If someone can help me, I would appreciate it!
@wbraganca can you show us the code used in the 'Demo 3 - (Nested Dynamic Form)'?
i am waiting for this example code over 3 months... will it be ever given ?
Suggest closing this issue - reference Wiki. https://github.com/wbraganca/yii2-dynamicform/wiki/Nested-Forms-Example
I'm having a problem with this solution. In my case then I change something in nested form (in my case is Program and ProgramItem) fe remove or add ProgramItem, the script adds empty record for each Program.
I check my code couple of time to find out if I missed something from the tutorial, but failed to find anthnig odd.
Here's the code.
public function actionUpdate($id)
{
$model = $this->findModel($id);
$this->oldFiles = $model->getImageFiles();
$this->oldFileNames = $model->getImageFileNames();
// retrieve existing Payment data
$oldProgramIds = Program::find()->select('id')->asArray()->all();
$oldProgramIds = ArrayHelper::getColumn($oldProgramIds,'id');
$modelsProgram = Program::findAll(['id' => $oldProgramIds]);
$modelsProgram = (empty($modelsProgram)) ? [new Program()] : $modelsProgram;
// retrieve existing Loads data
$oldProgramItemIds = [];
foreach ($modelsProgram as $i => $modelProgram) {
$oldItems = ProgramItem::findAll(['program_id' => $modelProgram->id]);
$modelsProgramItem[$i] = $oldItems;
$oldProgramItemIds = array_merge($oldProgramItemIds,ArrayHelper::getColumn($oldItems,'id'));
$modelsProgramItem[$i] = (empty($modelsProgramItem[$i])) ? [new ProgramItem()] : $modelsProgramItem[$i];
}
if ($model->load(Yii::$app->request->post())){
$this->image = $model->uploadImage();
if($this->image === false){
$model->information_images = json_encode($this->oldFileNames);
}
$modelsProgram = DynamicForms::createMultiple(Program::className(),$modelsProgram);
DynamicForms::loadMultiple($modelsProgram, Yii::$app->request->post());
$newProgramIds = ArrayHelper::getColumn($modelsProgram,'id');
$newProgramItemIds = [];
$itemsData['_backendCsrf'] = Yii::$app->request->post()['_backendCsrf'];
for($i=0;$i<count($modelsProgram);$i++){
$itemsData['ProgramItem'] = Yii::$app->request->post()['ProgramItem'][$i];
$modelsProgramItem[$i] = DynamicForms::createMultiple(ProgramItem::classname(),$modelsProgramItem[$i] ,$itemsData);
DynamicForms::loadMultiple($modelsProgramItem[$i], $itemsData);
$newProgramItemIds = array_merge($newProgramItemIds,ArrayHelper::getColumn($itemsData['ProgramItem'],'id'));
}
// delete removed data
$delItemIds = array_diff($oldProgramItemIds,$newProgramItemIds);
if (! empty($delItemIds)) ProgramItem::deleteAll(['id' => $delItemIds]);
$delProgramIds = array_diff($oldProgramIds,$newProgramIds);
if (! empty($delProgramIds)) Program::deleteAll(['id' => $delProgramIds]);
// validate all models
$valid = $model->validate();
$valid = Program::validateInformation($modelsProgram, $modelsProgramItem);// && $valid;
// save deposit data
if ($valid) {
if ($this->saveInformation($model, $modelsProgram, $modelsProgramItem)) {
if($this->image !== false){
foreach($this->oldFiles as $of){
unlink($of);
}
foreach ($this->image as $i) {
$path = $model->getImageFile($i);
$i->saveAs($path);
}
}
Yii::$app->getSession()->setFlash('success','Zapisano wszystkie dane');
return $this->redirect(['update','id'=>$id]);
}
}
}
// show VIEW
return $this->render('update2', [
'model' => $model,
'modelsProgram' => $modelsProgram,
'modelsProgramItem' => $modelsProgramItem,
]);
}
I appreciate any help.
I attach my screens
how should be the _controller (actionUpdate & actionCreate) if i want to have two dynamic forms in one view
@cloudcaptain I'm using your solution and creation is working correctly, but the update is working partially in my case.
Let me explain using your example...
I can Create a Deposit with many Payments and many Loads for each Payment (works properly).
On Update, i can add some Loads for Payments, but when i try to add a new Payment and new Loads for this new Payment, i got an error Undefined offset: 2 // for example
The error occurs near this section:
// get Slots data from POST
$newSlotIds = [];
$loadsData['_csrf'] = Yii::$app->request->post()['_csrf'];
for ($i=0; $i < count($modelsGrupos); $i++) {
$loadsData['MissaoSlot'] = Yii::$app->request->post()['MissaoSlot'][$i];
// ERROR POINTS TO THE LINE BELOW
$modelsSlots[$i] = Model::createMultiple(MissaoSlot::classname(), $modelsSlots[$i], $loadsData);
Model::loadMultiple($modelsSlots[$i], $loadsData);
$newSlotIds = array_merge($newSlotIds, ArrayHelper::getColumn($loadsData['MissaoSlot'], 'id'));
}
I have reviewed all my code following his example and didn't find the error. Could you help me?
My Update Action in Controller:
public function actionUpdate($id)
{
// retrieve existing Missao (mission) data
$model = $this->findModel($id);
// retrieve existing Grupos (groups) data
$oldGrupoIds = MissaoGrupo::find()->select('id')->where(['missao_id' => $id])->asArray()->all();
$oldGrupoIds = ArrayHelper::getColumn($oldGrupoIds,'id');
$modelsGrupos = MissaoGrupo::findAll(['id' => $oldGrupoIds]);
$modelsGrupos = (empty($modelsGrupos)) ? [new MissaoGrupo] : $modelsGrupos;
// retrieve existing Slots data
$oldSlotIds = [];
foreach ($modelsGrupos as $i => $modelGrupo) {
$oldSlots = MissaoSlot::findAll(['grupo_id' => $modelGrupo->id]);
$modelsSlots[$i] = $oldSlots;
$oldSlotIds = array_merge($oldSlotIds, ArrayHelper::getColumn($oldSlots, 'id'));
$modelsSlots[$i] = (empty($modelsSlots[$i])) ? [new MissaoSlot()] : $modelsSlots[$i];
}
// handle POST
if ($model->load(Yii::$app->request->post())) {
// Pega os Grupos via POST
$modelsGrupos = Model::createMultiple(MissaoGrupo::classname(), $modelsGrupos);
Model::loadMultiple($modelsGrupos, Yii::$app->request->post());
$newGrupoIds = ArrayHelper::getColumn($modelsGrupos, 'id');
// get Slots data from POST
$newSlotIds = [];
$loadsData['_csrf'] = Yii::$app->request->post()['_csrf'];
for ($i=0; $i < count($modelsGrupos); $i++) {
$loadsData['MissaoSlot'] = Yii::$app->request->post()['MissaoSlot'][$i];
$modelsSlots[$i] = Model::createMultiple(MissaoSlot::classname(), $modelsSlots[$i], $loadsData);
Model::loadMultiple($modelsSlots[$i], $loadsData);
$newSlotIds = array_merge($newSlotIds, ArrayHelper::getColumn($loadsData['MissaoSlot'], 'id'));
}
// delete removed data
$delSlotIds = array_diff($oldSlotIds, $newSlotIds);
if (! empty($delSlotIds)) MissaoSlot::deleteAll(['id' => $delSlotIds]);
$delGrupoIds = array_diff($oldGrupoIds, $newGrupoIds);
if (! empty($delGrupoIds)) MissaoGrupo::deleteAll(['id' => $delGrupoIds]);
// validate all models
$valid = $model->validate();
$valid = $this->validaMissao($modelsGrupos, $modelsSlots) && $valid;
if ($valid) {
if ($this->saveMissao($model, $modelsGrupos, $modelsSlots)) {
return $this->redirect(['view', 'id' => $model->id]);
}
}
}
return $this->render('update', [
'model' => $model,
'modelsGrupos' => $modelsGrupos,
'modelsSlots' => $modelsSlots,
]);
}
Sorry for my bad english!
EDIT (SOLVED)
http://stackoverflow.com/questions/32585832/yii-2-nested-forms
Of course:
public static function validaMissao($modelsGrupos, $modelsSlots)
{
$valid = true;
foreach ($modelsGrupos as $i => $modelGrupo) {
$valid = $modelGrupo->validate() && $valid;
$valid = Model::validateMultiple($modelsSlots[$i]) && $valid;
}
return $valid;
}
I solved the question above with StackOverflow help: http://stackoverflow.com/questions/32585832/yii-2-nested-forms
thx i solved actionCreate, but now I've been following the example for actionUpdate and i get this when i click on the update button

Guys, I had the same issue here: i have a form with two nested forms in it, and the second form's add button appends a first nested form's item, I solved it changing the widgetContainer param in DynamicFormWidget initialization.
Hope it helps!
@asaenzestrada its works thx a lot, but now actionUpdate give me this error PHP Warning – yii\base\ErrorException
array_combine(): Both parameters should have an equal number of elements
this happends here
$modelsModelo03 = Model::createMultiple(Modelo03::classname(), $modelsModelo03);
anytime that i call createMultiple in my actionUpdate i get the same
@epulgaron You have to adjust your controller to process the nested forms. Use Xdebug to check the values on execution and find data you need in \Yii::$app->request->post(), there is a multidimensional array with the form data, You should load it to your models.
