Validate select2 in yii2

Question

Ich habe eine textInput in _form.php. Dann ändere ich es select2. Aber nachdem ich es geändert habe, funktioniert die Validierung nicht. Was ist das Problem? Wie kann ich eine Validierung in select2 vornehmen, so dass sie nicht leer sein kann? Dieser ist der Code:

_form.php

<?php 

     $formatJs = <<< 'JS' 
     var formatPenerima = function (penerima) { 
      if (penerima.loading) { 
       return penerima.text; 
      } 
      var markup = 
      '<div class="row">' + 
       '<div class="col-sm-4">' + 
        '<b style="margin-left:5px">' + penerima.text + '</b>' + 
       '</div>' + 
       '<div class="col-sm-3"><i class="fa fa-phone"></i> ' + penerima.telepon + '</div>' + 
       '<div class="col-sm-4"><i class="fa fa-envelope"></i> ' + penerima.mail + '</div>' + 
      '</div>'; 
      return '<div style="overflow:hidden;">' + markup + '</div>'; 
     }; 
     var formatPenerimaSelection = function (penerima) { 
      return penerima.id || penerima.text; 
     } 
JS; 

     // Register the formatting script 
     $this->registerJs($formatJs, \yii\web\View::POS_HEAD); 

     // Script to parse the results into the format expected by Select2 
     $resultsJs = <<< JS 
     function (data, params) { 
      params.page = params.page || 1; 
      return { 
       results: data.results, // check here 
       /*pagination: { 
        more: (params.page * 30) < data.total_count 
       }*/ 
      }; 
     } 
JS; 

     $url = Url::to(['/paket/jsonlist']); 

     // Render your widget 
     // Get data from dummy data 
     echo $form->field($model, 'no_induk')->widget(Select2::className(), [ 
      'name' => 'kv-repo-template', 
      'value' => '', 
      'initValueText' => '', 
      'options' => ['placeholder' => 'Cari pemilik ...', 'id' => 'pengambil'], 
      'pluginOptions' => [ 
       'allowClear' => true, 
       'minimumInputLength' => 1, 
       'ajax' => [ 
        'url' => $url, 
        'dataType' => 'json', 
        'delay' => 250, 
        'data' => new JsExpression('function(params) { return {q:params.term, page: params.page}; }'), 
        'processResults' => new JsExpression($resultsJs), 
        'cache' => true 
       ], 
       'escapeMarkup' => new JsExpression('function (markup) { return markup; }'), 
       'templateResult' => new JsExpression('formatPenerima'), 
       'templateSelection' => new JsExpression('formatPenerimaSelection'), 
      ], 
     ])->label('Pemilik'); 
    ?> 

und das ist mein Modell Regeln:

public function rules() 
    { 
     return [ 
      [['no_induk', 'nama', 'no_telepon', 'email', 'kategori_paket', 'nama_pengirim'/*, 'tanggal_sampai'*/], 
       'required', 'message' => '{attribute} tidak boleh kosong.'], 
      [['id_satpam_pengentry'], 'required', 'message' => 'Nama satpam tidak boleh kosong.'], 
      [['kategori_paket', 'status', 'id_satpam_pengentry', 'id_satpam_penyetuju'], 'integer'], 
      [['tanggal_sampai', 'tanggal_pengambilan'], 'safe'], 
      [['no_induk', 'email'], 'string', 'max' => 255], 
      [['nama', 'nama_pengirim', 'nama_pengambil'], 'string', 'max' => 128], 
      [['no_telepon'], 'string', 'max' => 64] 
     ]; 
    } 

Answer 1

Sie class => "Form-control" in Ihre Optionen zu setzen haben und entfernen ID, so wird die Validierung

Answer 2

echo $form->field($model, 'no_induk')->widget(Select2::className(), [ 
     'name' => 'kv-repo-template', 
     'value' => '', 
     'initValueText' => '', 
     'options' => ['placeholder' => 'Cari pemilik ...', 'class' => 'form-control'], 
     'pluginOptions' => [ 
      'allowClear' => true, 
      'minimumInputLength' => 1, 
      'ajax' => [ 
       'url' => $url, 
       'dataType' => 'json', 
       'delay' => 250, 
       'data' => new JsExpression('function(params) { return {q:params.term, page: params.page}; }'), 
       'processResults' => new JsExpression($resultsJs), 
       'cache' => true 
      ], 
      'escapeMarkup' => new JsExpression('function (markup) { return markup; }'), 
      'templateResult' => new JsExpression('formatPenerima'), 
      'templateSelection' => new JsExpression('formatPenerimaSelection'), 
     ], 
    ])->label('Pemilik');
