Multiple nested widget example

[wennaspeedy]

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.

[s-filko]

+1 one more example.. Thank you.

[dina-samy]

+1 My problem is when pressing add for the second level widget it add the first within. How can i separate forms. ?

[s-filko]

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)

[dina-samy]

Thank you for your prompt reply. Much appreciated

[wennaspeedy]

I hope wbraganca helps us.

[skeeran]

did any find a it out how to do?

[kaarleenzz]

I don't think its supported in that manner. Otherwise we would know by now. I hope I'm wrong though :)

[skeeran]

thats the picture he uploaded... so it musst be possible :D

[wennaspeedy]

this image isnt our scenario :(. really, look at it again...

[skeeran]

is it possible with this widget to have Multiple nested inputs ???

[wbraganca]

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.

[skeeran]

okay cool Thank you. I am eagerly waiting for this example.

[jgrasta]

'dynamic-form']); ?>

is it possible to have multitple "dynamic-form" in the same view

[cratemos666]

I am also interested if I can have more dynamic forms in the same form.. If someone can help me, I would appreciate it!

[kaarleenzz]

@wbraganca can you show us the code used in the 'Demo 3 - (Nested Dynamic Form)'?

[skeeran]

i am waiting for this example code over 3 months... will it be ever given ?

[cloudcaptain]

waiting for the example - please post

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

[epulgaron]

how should be the _controller (actionUpdate & actionCreate) if i want to have two dynamic forms in one view

[jonatasfl]

@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!

[epulgaron]

plz let me see your validaMissao function

[jonatasfl]

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;
 }

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

Please post your actionUpdate code and i'll try to help you.

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.
