Menu
I have a piece of code and I'm trying to find out why one variation works and the other doesn't.
return View::make('gameworlds.mygame', compact('fixtures'), compact('teams'))->with('selections', $selections); This allows me to generate a view of arrays for fixtures, teams and selections as expected.
However,
return View::make('gameworlds.mygame', compact('fixtures'), compact('teams'), compact('selections')); does not allow the view to be generated properly. I can still echo out the arrays and I get the expected results but the view does not render once it arrives at the selections section.
It's oké, because I have it working with the ->with() syntax but just an odd one.
Thanks. DS

with() is a Laravel function and compact() is a PHP function and have totally different purposes. with() allows you to pass variables to a view and compact() creates an array from existing variables given as string arguments to it.
Using compact() in Laravel So with() allows you to pass variables to a view and compact() creates an array from existing variables given as string arguments to it. Below is an example of how we'd use the compact function. $user = User::all();
The difference is that => is the assign operator that is used while creating an array. For example: array(key => value, key2 => value2) And -> is the access operator. It accesses an object's value. Follow this answer to receive notifications.
PHP | compact() Function The compact() function is an inbuilt function in PHP and it is used to create an array using variables. This function is opposite of extract() function. It creates an associative array whose keys are variable names and their corresponding values are array values.
The View::make function takes 3 arguments which according to the documentation are:
public View make(string $view, array $data = array(), array $mergeData = array()) In your case, the compact('selections') is a 4th argument. It doesn't pass to the view and laravel throws an exception.
On the other hand, you can use with() as many time as you like. Thus, this will work:
return View::make('gameworlds.mygame') ->with(compact('fixtures')) ->with(compact('teams')) ->with(compact('selections')); I just wanted to hop in here and correct (suggest alternative) to the previous answer....
You can actually use compact in the same way, however a lot neater for example...
return View::make('gameworlds.mygame', compact(array('fixtures', 'teams', 'selections'))); Or if you are using PHP > 5.4
return View::make('gameworlds.mygame', compact(['fixtures', 'teams', 'selections'])); This is far neater, and still allows for readability when reviewing what the application does ;)
