Create models

to start use the form builder, for example you need to add attributes to the model Post

• first create values table eg. 'posts_values', this table must contains the following columns: -- input_id (integer) // you may need to create foreign key to the table 'dynamic_form_inputs' -- value (text / json)
• add relation to the Post model :

  public function getValues(){
      return $this->hasMany(\wardany\dform\models\DynamicForm::className(), ['id' => 'input_id'])
          ->viaTable('post_values', ['post_id'=> 'id']);
  }
  

• add DynamicFormBuilderBehavior to the Model

    public function behaviors() {
          return[
              ...
              \wardany\dform\behaviors\DynamicFormBuilderBehavior::className(),
              ...
          ];
      }
  

• in the form page call the form drower widget

  <?= wardany\dform\widgets\InputViewerWidget::widget(['model'=> $model, 'form'=> $form]) ?>
  

• add DynamicFormSearchBehavior to the search model

    public function behaviors() {
          return[
              ...
              [
                  'class'=> \wardany\dform\behaviors\DynamicFormSearchBehavior::className(),
                  'values_table'=> PostValues::tableName(),
                  'relation_input'=> 'post_id'
              ]
              ...
          ];
      }
  

• in the form page call the form drower widget

  <?= wardany\dform\widgets\SearchViewerWidget::widget(['model'=> $model, 'form'=> $form]) ?>
