如何在不使用LARAVEL中的PHP“紧凑”功能的情况下使用视图

Question

I'm working on laravel to fetch data from database and store that data or array of data into the variable like $tasks store data of tasks table from database up till everything is fine but during processing the $task variable it is necessary to use "compact" function ?

And can anyone explain this

Route::get('/test', function () {

$data   =   [
                'name'  =>  'Vrushal',
                'last'  =>  'Raut',
                'tasks' =>  [
                                'Programming',
                                'UI/UX Developement',
                                'Cloud Expert'
                            ]
            ];
            //return view('templates/test', compact($data)); //NOT WORKING
            //return view('templates/test', $data); // ITS WORKING
            return View::make('templates/test',$data); // ITS WORKING
}); 

As well as with Database plz explain this

Route::get('/tasks', function(){

$tasks  =   DB::table('tasks')->get();

return view('templates/tasks', compact('tasks')); // ITS WORKING
//return View::make('templates/test',$tasks); // NOT WORKING
});

Thanks in Advance!

Answer 1

compact('data') is the same as ['data' => $data] , so to be able to access Vrushal value, you'll need to do this in the view:

{{ $data['name'] }}

When you do this:

 View::make('templates/test', $data);

You can get Vrushal value with:

{{ $name }}

compact — Create array containing variables and their values Manual http://php.net/manual/en/function.compact.php

<?php

$city  = "San Francisco";
$state = "CA";
$event = "SIGGRAPH";

$result = compact("event", "city", "state");
print_r($result);
//return view('templates/test', compact("event", "city", "state")); // ITS WORKING

Result

Array
(
    [event] => SIGGRAPH
    [city] => San Francisco
    [state] => CA
)

---

$arr = array(
    "city"  => "San Francisco",
    "state" => "CA",
    "event" => "SIGGRAPH"
);

extract($arr);    
$result = compact(array_keys($arr));
print_r($result);
//return view('templates/test', compact(array_keys($arr)); // ITS WORKING

Result

Array
(
    [event] => SIGGRAPH
    [city] => San Francisco
    [state] => CA
)

---

$arr = array(
     "city"  => "San Francisco",
     "state" => "CA",
     "event" => "SIGGRAPH"
);
print_r($arr);
//return view('templates/test', $data); // ITS WORKING

Result

Array
(
    [event] => SIGGRAPH
    [city] => San Francisco
    [state] => CA
)

---

$arr = array(
     "city"  => "San Francisco",
     "state" => "CA",
     "event" => "SIGGRAPH"
);
$result = compact($arr);
print_r($result);
//return view('templates/test', compact($arr)); //NOT WORKING

Result

Array
(

)

Answer 3

//return view('templates/test', compact($data)); //NOT WORKING //return view('templates/test', compact($data)); //NOT WORKING its not working because you don't need dollar sign for compact elements. It should look like this:

return view('templates.test', compact('data')); and then you can access it by $data[] variable inside view.

Other way:

return view('templates.test')->with('variable', $data); and accessing this in view with $variable[]
