Codeigniter passing dynamic data from controller to view. And Mapping values to controller array variable

I want to get the array from controller to views which is dynamic.

Suppose,

Controller

 $a = array(array('category_id'=>'3', 'name'=>'car'),array('category_id'=> '5', 'name'=>'bike'));
 $data['category'] = $a;
 foreach($a as $val){
     $data[$val['name']] = $this->home_model->get_product($val['category_id']);
 }
 $this->load->view('main',$data);

View (main.php)

 foreach($category as $val){
    foreach($val['name'] as $value){     //undefined variable passed to foreach, But when I var_dump variable are printed in controller but cannot get in views. How to map the value, to value that is passed from controller.

    }
 }

Now the $data array in controller will be:

 array (size=6)
'Car' =>  
 array (size=1)
  0 => 
    object(stdClass)[31]
      public 'frontend_id' => string '3' (length=1)
      public 'sub_category_id' => string '3' (length=1)
      public 'category_id' => string '3' (length=1)
      public 'name' => string 'Car' (length=3)
      public 'slug' => string 'car' (length=3)
      public 'parent_id' => string '1' (length=1)
      public 'description' => string '' (length=0)
      public 'status' => string '1' (length=1)

When I loop through $category in the view then, I can get car value as

  foreach($category as $val) {
      $name = $val['name'];            //prints car
      foreach($name as $value) {       //how to map $name to the 'car' array that is passed from controller. It say invalid argument supplied for foreach

      }
  }

I'h tested code with your data. Its fine. So this should work

My Testing Code

$a = array(
        array('category_id'=>'3', 'name'=>'car'),
        array('category_id'=> '5', 'name'=>'bike')
    );
$data['category'] = $a;
foreach($a as $val)
{
    $name = $val['name'];
    // $category_id = $this->home_model->get_product($val['category_id']);
    $category_id = $val['category_id']+5;

    $NewVal[] = array(
                    'name' => $name, 
                    'category_id' => $category_id
                );

}
print_r($NewVal);

Output

Array ( [0] => Array ( [name] => car [category_id] => 8 ) [1] => Array ( [name] => bike [category_id] => 10 ) )

In Your case - as solution

In Controller

$a = array(
        array('category_id'=>'3', 'name'=>'car'),
        array('category_id'=> '5', 'name'=>'bike')
    );
$data['category'] = $a;
foreach($a as $val)
{
    $name = $val['name'];
    $category_id = $this->home_model->get_product($val['category_id']);

    $NewVal[] = array(
                    'name' => $name, 
                    'category_id' => $category_id
                );
}

$data['category_new'] = $NewVal;

In View

foreach ($categorys_new as $category) {
    print_r($category);
    echo "<br>";
}

add $ before $val['name']. See below code

On your View

foreach($category as $val)
{
    foreach($$val['name'] as $value){     

    }
}

Your controller should be:-

 $res= $data = [];
 $a = array(array('category_id'=>'3', 'name'=>'car'),array('category_id'=> '5', 'name'=>'bike'));
 foreach($a as $val){
     $res[$val['name']] = $this->home_model->get_product($val['category_id']);
 }
 $data['category'] = $res;
 $this->load->view('main',$data);

Your view should be:-

 foreach($data['category'] as $val){
    foreach($val['name'] as $value){     
         // do your stuff
    }
 }

Array $a should be like,

$a[0] = array('category_id'=>'3', 'name'=>'car');
$a[1] = array('category_id'=>'5', 'name'=>'bike');

$data['category'] = $a;

Try this
