[SOLVED]Comparing Radio button value

Yii 2.0 General Discussions

Hello experts,

Can you guide me where i am going wrong with the below code.
I want to compare selected radio button value with some value. I am getting undefined variable error.

Model Code:
<?php

namespace frontend\models;

use Yii;

class IncForm extends \yii\db\ActiveRecord
{
    //public $id;
   
    // public $name;
    // public $maxlim;

    public static function tableName()
    {
        return 'test';
    }
  
    public function rules()
    {
        return [
                  [['name','maxlim'], 'safe'],
                  ];
    }
} 

Controller Code:
    <?php 

namespace frontend\controllers;


use Yii;
use yii\base\Model;
use yii\web\Controller;
use frontend\models\IncForm;



class TestController extends Controller

{
	public function actionTest(){

	function shuffle_arr($arr){
		 $keys = array_keys($arr);
		 shuffle($keys);
		 foreach($keys as $key) {
		  $shuffeled[$key] = $arr[$key];
		 }
		 return $shuffeled;
		}
		$x=rand(100,999);
		$y=rand(1,9);
		
		$answers=shuffle_arr([$x=>$x,$y=>$y]);
		//$maxlim = ($x == $answers) ? "Yes" : "No";
		if ($answers==$x) {
			$maxlim="Yes";
		}else{
			$maxlim="No";
		}
		
		$model = new IncForm();
		
			if ($model->load(Yii::$app->request->post()) && $model->save()) {
			return $this->refresh();
					}
			return $this->render('test', [
								'answers'=>$answers,
          				     			 'model' => $model,
          				     		]);

 }

View Code:
    

<div id= "content">

            <?php $form = ActiveForm::begin([
                        'id' => 'form-test'])?>
     
     <div class="col-sm-6"> 
<div class="qr" id="rlist"> 
	   <?= $form->field($model, 'name')->radioList($answers,['onchange'=>'document.getElementById("form-test").submit()'])->label(false); ?>
         
        </div>
</div>
<?php ActiveForm::end() ?>
</div>

Your code seems to be working fine for me. What variable is the error for?

Hello Steve,

Here is slightly modified code. I want to compare the value of the selected radio button with the $x variable. But it is unable to compare. If the selected value is equal to $x then the value of “maxlim” should return “Yes”. Else it will return the value of “maxlim” “No”.

  public function actionTest(){
	 function shuffle_arr($arr){
		 $keys = array_keys($arr);
		 shuffle($keys);
		 foreach($keys as $key) {
		  $shuffeled[$key] = $arr[$key];
		 	}
		 return $shuffeled;
		}

	$x=rand(100,999);
	$y=rand(1,9);
	
	
	$answers=shuffle_arr([$x=>$x,$y=>$y]);
	
	$model = new IncForm();
	$model->maxlim = ($model->name==$x) ? "Yes" : "No";
		if ($model->load(Yii::$app->request->post()) && $model->validate()) {
		// var_dump($model->name);
                // var_dump($model->maxlim);
                // die();

			if($model->save()){
		        return $this->refresh();
				}
			}
				return $this->render('test', [
							'answers'=>$answers,
      				     			'model' => $model,
      				     		]);

}

I’m not quite sure what you’re wanting to do with the result, but you should be assigning $maxlim after you load the posted data into your model. Maybe something like this:

if ($model->load(Yii::$app->request->post())) {
        $model->maxlim = ($model->x == $_POST['IncForm']['name']) ? "Yes" : "No";
        $model->save();
        return $this->refresh();
} else {
    $x=rand(100,999);
    $y=rand(1,9);        
    $answers=shuffle_arr([$x=>$x,$y=>$y]);
    $model->x = $x;
    return $this->render('test', [
        'answers'=>$answers,
        'model' => $model,
    ]);
}

You will need a way to preserve $x after the submit so you have something to compare to. You could put it in a hidden input or add $x attribute to your model.
