Passing variable's value from controller to another controller

Question

I have two separate controllers which are PostController for returning input value to blade and APIController for returning data from the database to blade. I have tried passing the variable with SESSION but still no function. Please help.

Index.blade.php

<form class="form-inline" action="{{ action('PostController@index') }}" method="GET">
   <div class="form-group">
      <label class="mb-2 mr-sm-2 col-form-label">Date : </label>
         <input type="date" name="date" id="date" style="width:160px;" class="form-control mb-2 mr-sm-2" value="<?php if(isset($_GET['submit'])) echo $_GET['date']; else echo date('Y-m-d');?>">
   </div>
   <input type="submit" name="submit" class="btn btn-primary mb-2" value="Inquiry">
</form>

PostController.php

<?php
   namespace App\Http\Controllers;

   use Illuminate\Support\Facades\Input;
   use Session;

   class PostController extends Controller
   {
      public function index()
      {     
         $getDate = Input::get('date'); //trying to pass this to APIController for query
         $getCurrentDate = date('Y-m-d');

         Session::put('getDate', $getDate); //for example $getDate = '2019-01-01'

         return view('posts.index')->with('getCurrentDate', $getCurrentDate)->with('getDate', $getDate);
      }
   }

APIController.php

<?php    
   namespace App\Http\Controllers;

   use Illuminate\Support\Facades\DB;
   use Yajra\Datatables\Datatables;
   use Session;

   class APIController extends Controller
   {
      public function getQueries()
      {
         ini_set('memory_limit', '1024M');
         ini_set('max_execution_time', 300);

         $getInputDate = Session::get('getDate'); //don't get anything here

         //dd($getInputDate); //have tried dumping, it returns null

         $getCurrentDate = date('Y-m-d');

         if($getInputDate == NULL)
         {
            $query = DB::select(DB::raw("SELECT * FROM TABLE WHERE date = '$getCurrentDate'");

            return Datatables::of($query)->make(true); 
         }
         else 
         {
            $query = DB::select(DB::raw("SELECT * FROM TABLE WHERE date = '$getInputDate'");

            return Datatables::of($query)->make(true);
         }
      }
   }

Web.php

Route::get('/', 'PostController@index');  

Route::group(['middleware' => 'web'], function () {
    // Put routes in here
    Route::get('/json/getQueries', 'APIController@getQueries')->name('api.posts.index');
});

Api.php

Route::get('/json/getQueries', 'APIController@getQueries')->name('api.posts.index');

Route::group(['middleware' => 'web'], function () {
    // Put routes in here
    Route::get('/', 'PostController@index'); 
});

You can accomplish this using laravel custom-channels. Documetation: laravel.com/docs/5.4/notifications#custom-channels — handlerFive

@RonS custom channels can pass it even though for separate controller? — Richmond

Try putting the affected routes within the web middleware group, so you should share the session between them.

Route::group(['middleware' => 'web'], function () {
    // Put routes in here
});

If I'm not mistaken, this case should be for the api routes, which want to share the sessions with the web routes.

It's working. It must be added in both routes in order to work. I have updated my post

In controller add use Session; it will work.

https://laravel.com/docs/5.2/session#adding-custom-session-drivers

//use Illuminate\Support\Facades\Session;  
 use Session;

I tried the same concept it's working for me.

I tried it just now. Still not working. I try dd($getInputDate) inside APIController, it returns null.

Shivendra Singh Over a year ago

did you update in both the controller? after update submit the form then check.

In PostController what value you are getting of ' $getDate '?

Richmond Over a year ago

Date format like this 2019-01-01 but it only will have value when I submit the form. If not submitted yet, then $getDate is null. So in APIController will check if null, display current date of data. If not null, then display data based on the date submitted.
