cant get value from dynamic checkboxlist

hello guys,

i have some problem when using checkboxlist. this checkboxlist was dependent with dropdownlist.

checkboxlist generate when i choose one value in dropdownlist.

then checkboxlist will generate by ID.

the problem is when i save the form, i cant get the value from the that generated checkboxlist.

this the code from view and my controller

- region view 

   <?= $form->field($model, 'cp_countrytarget')->dropDownList(

        ArrayHelper::map(\app\models\Countries::find()->all(), 'countries_id', 'name'),

        [

          'prompt' => 'Select Country',

          'class' => 'dependent-input form-control',

          'onchange' => '$.get("index.php?r=tbcampaign/countries&id='.'"+$(this).val(), function(data) {

            $("#tbcampaign-cp_statetarget").html(data);

          });'

        ]); ?>


         <?=

            $form->field($model, 'cp_statetarget[]')->checkboxlist([],

            [

             //'onclick' => "$(this).val($('input:checkbox:checked').val()); ",

             //'onclick' => "alert($('input[type=checkbox]').val()); ",

            ]);

          ?>


-region controller


  public function actionCountries($id)

  {

    $states = States::find()->where(['country_id' => $id])->all();


    foreach ($states as $state)

    {

      return Html::checkboxList('Tbcampaign[cp_citiestarget][]',[],ArrayHelper::map($states, 'name', 'name'), []);

    }

but if i generate checkboxlist like this i can save the form normally to database, but thats not dynamically.

- view

<div class="container" style="overflow-y:scroll; width:auto; height:250px;">

        <?php $datacities = ArrayHelper::map(\app\models\States::find()->all(), 'name', 'name');

        ?>

        <?= $form->field($model, [cp_citiestarget][]')->checkboxList$datacities [

              'separator' => '',

              'itemOptions' => [

              'class' => 'cities'

             ]

             ]);

            ?>

            <?=   $this->registerJs("jQuery('#checkAll').change(function(){jQuery('.cities').prop('disabled',this.checked?'checked':'');


            })");?>

        </div>

whats wrong with that my dynamically checkboxlist?

*sorry for my bad english

thankyou

Hi shotokhaw, welcome to the forum.

Can you show us your model for the form and the controller code that saves the user input?

I mean, I’d like to see how you handles the array values of the checkbox list.

BTW, please take some time to look at the following wiki:

How to create/update a model with its related items using Listbox or CheckboxList

The article explains how to create a model that handles the array values returned by checkboxlist.

hai softark, sorry for late reply i was left my laptop in office.

okay this is my model from the form

<?php

namespace app\models;


use Yii;


class Tbcampaign extends \yii\db\ActiveRecord

{

    /**

     * @inheritdoc

     */

    public static function tableName()

    {

        return 'tbcampaign';

    }


    /**

     * @inheritdoc

     */

    public function rules()

    {

        return [

            [['client_name','client_id', 'cp_name','cp_adult'], 'required'],

            [['client_name','cp_name','cp_tag','cp_adult'], 'string', 'max' => 25],

            [['cp_startdate','cp_enddate','client_id'], 'integer'],

            [['cp_pricingoffer'], 'string', 'max' => 25],

            [['gambar','cp_devicetarget','cp_ostarget','cp_browser','cp_language','cp_timetarget','cp_iptarget'], 'string', 'max' => 50],

            [['cp_activate'], 'string', 'max' => 1],

            [['cp_pricingmodel'], 'string', 'max' => 3],

            [['cp_budget'],'integer'],

            [['cp_countrytarget','cp_statetarget'],'safe'],

        ];

    }


    public function attributeLabels()

    {

        return [

            'client_name' => 'Client Name',

            'client_id' => 'Client ID',

            'cp_name' => 'Name',

            'cp_tag' => 'Tag',

            'cp_startdate' => 'Campaign Start Date',

            'cp_enddate' => 'Campaign End Date',

            'cp_activate' => 'Activate Campaign After Create',

            'cp_budget' => 'Total Budget for This Campaign',

            'cp_adult' => 'Campaign Adult Target',

            'cp_countrytarget' => 'Country Target',

            'cp_statetarget' => 'State Target',

        ];

    }

}

and then this is my controller code for save the data

<?php

namespace frontend\controllers;


use Yii;

use app\models\Tbcampaign;

use app\models\Countries;

use app\models\Cities;

use app\models\States;

use yii\web\Controller;

use yii\helpers\Json;

use yii\helpers\ArrayHelper;

use yii\helpers\Html;


/**

 * manual CRUD

 **/

class TbcampaignController extends Controller

{

    /**

     * Create

     */




    public function actionCreate()

    {

        $model = new tbcampaign();


        if ($model->load(Yii::$app->request->post())) {


            $id = $model->cp_countrytarget;

            echo $id ."<br/>";


            $getCountry = ArrayHelper::map(Countries::find()->where(['countries_id'=>$id])->all(),'name','name');


            foreach ($getCountry as $items) {


              $model->cp_countrytarget = $items;

            }


            if($model->save()){

              echo '1'; //success

            }else {

              echo '0'; //failed save

            }


        } else {

          // $model->cp_countrytarget = explode(',',$model->cp_countrytarget);

          // $model->cp_statetarget = explode(',',$model->cp_statetarget);


          $this->layout="adminlte";

          return $this->render('create', [

            'model' => $model,


          ]);

        }

    }




  public function actionCountries($id)

  {

    $states = States::find()->where(['country_id' => $id])->all();


    foreach ($states as $state)

    {

   

      return Html::checkboxList('Tbcampaign[cp_citiestarget][]',[],ArrayHelper::map($states, 'name', 'name'), []);

    

    }


  }

 }

 ?>

thankyou

How do you define ‘cp_statetarget’ in your database table? Is it a text?

If it’s a text(string), then you have to convert it to and from an array of values for the checkboxlist.

i must be use the implode method like this? $model->cp_statetarget = implode(",", $model->cp_statetarget);

my problem is i cant get the value from this dynamic checkboxlist

<?=

            $form->field($model, 'cp_statetarget[]')->checkboxlist([],

            [


            ]); ?>

if i push the states from controller.

but if i use this condition not dynamic checkboxlist and at the controller i add $model->cp_statetarget = implode(",", $model->cp_statetarget);

i can save succesfully.

  

<div class="col-lg-2">

        <?php $datastates = ArrayHelper::map(\app\models\States::find()->where(['country_id'=>102])->all(), 'name', 'name');

        ?>

        <div>

        <label class="control-label">States</label>

        </div>

        <div>

        <label><input type="checkbox" id="checkAll">Check All</label>

        </div>

        <div class="container" style="overflow-y:scroll; width:auto; height:250px;">

        <?= $form->field($model, 'cp_statetarget[]')->checkboxList($datastates, [

            'separator' => '',

            'itemOptions' => [

            'class' => 'states'

           ]

           ])->label('');

          ?>

          <?=   $this->registerJs("jQuery('#checkAll').change(function(){jQuery('.states').prop('disabled',this.checked?'checked':'');


          })");?>


      </div>

I think that you are adding an unnecessary ‘[]’ to ‘cp_statetarget’ when naming the input.

view

    <?php /* echo $form->field($model, 'cp_statetarget[]')->checkboxlist([]); */ ?>

    <?php echo $form->field($model, 'cp_statetarget')->checkboxlist([]); ?>

controller

    public function actionCountries($id)

    {

        $states = States::find()->where(['country_id' => $id])->all();

        return Html::checkboxList('Tbcampaign[cp_citiestarget]',[], ArrayHelper::map($states, 'name', 'name'), []);

    }

i put some code for makesure that cp_statetarget can get value.

but still same result if i remove “[]” or without remove “[]”

  

if ($model->load(Yii::$app->request->post())) {


            $id = $model->cp_countrytarget;

            $model->cp_countrytarget = null;


//----region display state when save. but still didnt get value 

            $displayState = $model->cp_statetarget;


            echo $displayState;

//-----


            $getCountry = ArrayHelper::map(Countries::find()->where(['countries_id'=>$id])->all(),'name','name');


            foreach ($getCountry as $items) {

              $model->cp_countrytarget = $items;

            }


            if($model->cp_statetarget != null){

              $model->cp_statetarget = implode(",", $model->cp_statetarget);

            }else {

              $model->cp_statetarget = 'All';

            }


            if($model->cp_timetarget != null){

              $model->cp_timetarget = implode(",", $model->cp_timetarget);

            }else {

              $model->cp_timetarget = 'All';

            }


            if($model->save()){

              echo '1';

            }else {

              echo '0';

            }


        }

Would you please write a simplified minimized version of your code that illustrates your issue? The model, the controller and the view altogether. It’s very hard for me to tell what’s wrong with your code.

sorry sorry.

okay let my try.

i want to display dynamic checkbox (named cp_statetarget) depends from this dropdownlist (named cp_countrytarget).

• the view

<?= $form->field($model, 'cp_countrytarget')->dropDownList(

        ArrayHelper::map(\app\models\Countries::find()->all(), 'countries_id', 'name'),

        [

          'prompt' => 'Select Country',

          'class' => 'dependent-input form-control',

          'onchange' => '$.get("index.php?r=tbcampaign/countries&id='.'"+$(this).val(), function(data) {

            $("#tbcampaign-cp_statetarget").html(data);

          });'

        ]); ?>


  $form->field($model, 'cp_statetarget')->checkboxlist([],

    [


    ]); ?>

• the controller

public function actionCreate()

{

    $model = new tbcampaign();


      if ($model->load(Yii::$app->request->post())) {


          //region state

          if($model->cp_statetarget != null){

            $model->cp_statetarget = implode(",", $model->cp_statetarget);

          }else {

            $model->cp_statetarget = 'All';

          }

          //end region state

          if($model->save()){

          echo '1';

          }else {

            echo '0';

          }


      } else {


        $model->cp_statetarget = explode(',',$model->cp_statetarget);


        $this->layout="adminlte";

        return $this->render('create', [

          'model' => $model,


        ]);

      }

}




public function actionCountries($id)

  {

    $states = States::find()->where(['country_id' => $id])->all();


    foreach ($states as $state)

    {

      return Html::checkboxList('Tbcampaign[cp_citiestarget]',[],ArrayHelper::map($states, 'name', 'name'), []);

  }

-the models

public function rules()

    {

        return [

            [['cp_countrytarget','cp_statetarget','cp_timetarget'],'safe'],

        ];

    }


    public function attributeLabels()

    {

        return [

            'cp_statetarget' => 'State Targeting',

        ];

    }

my issue is why i cant get value from cp_statetarget if i use checkboxlist that depend on dropdownlist.

but if i use like this (i can get the value cp_statetarget successfully) :

-the view

  <?php $datastates = ArrayHelper::map(\app\models\States::find()->where(['country_id'=>102])->all(), 'name', 'name');

  ?>


    <?= $form->field($model, 'cp_statetarget[]')->checkboxList($datastates, [

      'separator' => '',

      'itemOptions' => [

        'class' => 'states'

      ]

      ])->label('');

      ?>

      <?=   $this->registerJs("jQuery('#checkAll').change(function(){jQuery('.states').prop('disabled',this.checked?'checked':'');


      })");?>

Is your dynamic checkboxlist generated as expected? I mean, does it change dynamically when you select the country?

yup thats working properly.

i was attached the screenshoot

Do you enable the ajax validation of the form? If so, please try disabling it and see what will happen.

yes i was enable the ajax validation.

then i try to disabling like this

<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]);

 // <php $form = ActiveForm::begin();['enableAjaxValidation'=>false],

still got nothing

I’m sorry, but I have no idea now.

If I were you, I would use XDebug in my IDE and trace the execution of the program in order to see what’s happening.
