如何在 Laravel 会话数组中添加项目

Question

I'm using Laravel 4.2. I have a method for storing files and I'm trying to push items in session array. Every time user clicks on a button, I want to save these file names in session array with a name and later I should get them.

I'm trying with the following code:

 $name = Input::get('name'); $input = Input::all(); foreach ($input[$name] as $key => $corporate) { $file_name = $key.'_'.$current_time . '_' . $corporate->getClientOriginalName(); //code for uploading files if(Session::has($name)) { Session::push($name.".".$key, $file_name); //I want to add new items in this array } else { Session::put($name, $file_name); //for first image } }

As I read from laravel docs:

Push A Value Onto An Array Session Value

Session::push('user.teams', 'developers');

);`

But it doesn't add new items to array, it overwrites it.

After first image upload in session array I have:

 ["director_front_passport[]"]=> array(1) { [1]=> array(1) { [0]=> string(54) "0_1472669237_12894473_678457885627912_1258115018_o.jpg" } }

After uploading second image, session is:

 ["director_front_passport[]"]=> array(1) { [2]=> array(1) { [0]=> string(33) "0_1472669255_animated_loading.gif" } }

What is the proper way to push items in session array with definite name, I mean I should get these items later using: Session::get('name') for example.

You can try the following code:

$name = Input::get('name');
$input = Input::all();
$items = Session::get($name, []);
foreach ($input[$name] as $key => $corporate) {
  $file_name = $key.'_'.$current_time . '_' . $corporate->getClientOriginalName();
  if (!array_key_exists($key, $items)) {
      $items[$key] = [];
  }
  $items[$key][] = $file_name;
}
Session::put($name, $items);
