如何在Laravel 4.2中将字符串回显到视图中？

Question

I am using Laravel 4.2 framework (will be upgraded soon) and am calling an artisan command from a controller with a return redirect back.

My issue is when I call the command, the command echo some stuff for me (which is helpful when I call it from the terminal) but now since am using it in a method, I want the same echos showing in my view as flash message.

I will write the following example just to clarify my issue.

My Command:

public function fire()
{ 
    // Do stuff.
    echo $vars 
}

My Controller:

function foo() {

      // Some input here

      Artisan::call('command');


      return Redirect::back(); // <-- want to add the echos of the command. 
}

So I want to show the $var in my views, am not sure if it's possible if not am open to other suggestions that can give me the same concept (keep in mind if am replacing the echo with something else it got to show in both view and terminal when I run the command).

Note: I tried Ajax but my issue was with me sending a file as param, tried the FormData Object but it didn't work with me.

Answer 1

Storing data in the session is a good way of keeping persistent data throughout multiple requests. Session flashing is a way to keep data just for the next request, which is perfect for redirects. Laravel uses this internally for old input data when there is a validation error.

https://laravel.com/docs/4.2/session#flash-data

Session::flash('key', 'value');

This will only be kept for the next request, in which you'd be able to use Session::get('key') to retrieve it.

I fixed the problem by changing my command little bit.

Command:

function fire()
{
  // replaced the echo with the following.
  $this->info('what ever you want ur message you want to put in console');

 }

Controller

function foo()
{

  $output =  new BufferedOutput();

  Artisan::call('command', [arguments], $output);

  return Redirect::back()->with('flash_message', $output->fetch());
}

Guess the buffered output works with command outputs which can be found in Laravel Documentations not echo's
