Laravel中出现“未定义的常数/变量”错误……无法在刀片中显示变量

Question

I am using laravel, I have a variable in my dashboard controller (which extends the base controller) defined as follows:

Dashboard Controller:

public function dashboardData(){
    $toReturn = array();
    $toReturn['siteTitle'] = $this->data['panelInit']->settingsArray['siteTitle'];


    //------other things-----------//


    $toReturn['stats'] = array();

    //------some other things-----------//


    $toReturn['stats']['recieved'] = messagesList::where('userId',$this->data['users']->id)->where('messageStatus',1)->count();

This variable is shown in my main(index/default/home/whatever you call it) html template by using the {{}} syntax as follows:

HTML Template

   <div class="counter">   
   <div class="informational">{{dashboardData.stats.recieved}}</div>
   </div>

and it completely shows the result I expect.... but I want to show this same data in a layout blade that I am using... I am using the same html structure in the layout.blade (directory:/app/views) with {{dashboardData.stats.recieved}} but I am getting " Undefined Constant " and " undefined Variable " errors...

following is a glimpse of my routes.php:-

routes.php

Route::group(array('prefix'=>'/','before'=>'auth.Ui|auth.token|api.csrf'),function(){
Route::get('/','DashboardController@index');

Route::get('/dashboard','DashboardController@dashboardData');
Route::get('/dashboard/baseUser','DashboardController@baseUser');

//-------------some things-------------//

Route::post('/dashaboard','DashboardController@dashaboardData');

I am quite new on laravel, I have stumbled upon the "view::share" and "view:make" thing but didn't quite get it how to do it perfectly & securely without a single error... I also have a library setup in the "/app/libraries/initiation.php" that reflects some data to layout.blade....How do I show the data {{dashboardData.stats.recieved}} in the layout.blade without the errors " Undefined Constant " and " undefined Variable "...??? and also what would be the most correct, practical and most importantly secure way of doing so...???

Answer 1

You access variables in incorrect way in your Blade template.

Replace

{{dashboardData.stats.recieved}}

with

{{$dashboardData['stats']['recieved']}}

Make sure that you pass the variable to the view from your controller:

public function dashboardData() {
  // your logic that generates $toReturn array

  return view('your_view')->with('dashboardData', $toReturn);
}
