问题
I have this site and one of its pages creates a simple list of people from the database. I need to add one specific person to a variable I can access.
How do I modify the return $view->with('persons', $persons);
line to also pass the $ms variable to the view?
function view($view)
{
$ms = Person::where('name', 'Foo Bar');
$persons = Person::order_by('list_order', 'ASC')->get();
return $view->with('persons', $persons);
}
回答1:
Just pass it as an array:
$data = [
'name' => 'Raphael',
'age' => 22,
'email' => 'r.mobis@rmobis.com'
];
return View::make('user')->with($data);
Or chain them, like @Antonio mentioned.
回答2:
This is how you do it:
function view($view)
{
$ms = Person::where('name', '=', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return $view->with('persons', $persons)->with('ms', $ms);
}
You can also use compact():
function view($view)
{
$ms = Person::where('name', '=', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return $view->with(compact('persons', 'ms'));
}
Or do it in one line:
function view($view)
{
return $view
->with('ms', Person::where('name', '=', 'Foo Bar')->first())
->with('persons', Person::order_by('list_order', 'ASC')->get());
}
Or even send it as an array:
function view($view)
{
$ms = Person::where('name', '=', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return $view->with('data', ['ms' => $ms, 'persons' => $persons]));
}
But, in this case, you would have to access them this way:
{{ $data['ms'] }}
回答3:
Use compact
function view($view)
{
$ms = Person::where('name', '=', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return View::make('users', compact('ms','persons'));
}

Passing multiple variables to a Laravel view
//Passing variable to view using compact method
$var1=value1;
$var2=value2;
$var3=value3;
return view('viewName', compact('var1','var2','var3'));
//Passing variable to view using with Method
return view('viewName')->with(['var1'=>value1,'var2'=>value2,'var3'=>'value3']);
//Passing variable to view using Associative Array
return view('viewName', ['var1'=>value1,'var2'=>value2,'var3'=>value3]);

Came across a similar problem, but if you do not necessarily want to return a view with view file, you can do this:
return $view->with(compact('myVar1', 'myVar2', ..... , 'myLastVar'));
回答6:
Please try this,
$ms = Person::where('name', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return View::make('viewname')->with(compact('persons','ms'));

This Answer seems to be
bit helpful while declaring the large numbe of variable in the function
Laravel 5.7.*
For Example
public function index()
{
$activePost = Post::where('status','=','active')->get()->count();
$inActivePost = Post::where('status','=','inactive')->get()->count();
$yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();
$todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();
return view('dashboard.index')->with('activePost',$activePost)->with('inActivePost',$inActivePost )->with('yesterdayPostActive',$yesterdayPostActive )->with('todayPostActive',$todayPostActive );
}
When you see the last line of the returns it not looking good
When You Project is Getting Larger its not good
So
public function index()
{
$activePost = Post::where('status','=','active')->get()->count();
$inActivePost = Post::where('status','=','inactive')->get()->count();
$yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();
$todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();
$viewShareVars = ['activePost','inActivePost','yesterdayPostActive','todayPostActive'];
return view('dashboard.index',compact($viewShareVars));
}
As You see all the variables as declared as array of $viewShareVars
and Accessed in View
But My Function Becomes very Larger so i have decided to make the line as very simple
public function index()
{
$activePost = Post::where('status','=','active')->get()->count();
$inActivePost = Post::where('status','=','inactive')->get()->count();
$yesterdayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(-1))->get()->count();
$todayPostActive = Post::whereDate('created_at', Carbon::now()->addDay(0))->get()->count();
$viewShareVars = array_keys(get_defined_vars());
return view('dashboard.index',compact($viewShareVars));
}
the native php function get_defined_vars()
get all the defined variables from the function
and array_keys
will grab the variable names
so in your view you can access all the declared variable inside the function
as {{$todayPostActive}}

For passing multiple array data from controller to view, try it. It is working. In this example, I am passing subject details from a table and subject details contain category id, the details like name if category id is fetched from another table category.
$category = Category::all();
$category = Category::pluck('name', 'id');
$item = Subject::find($id);
return View::make('subject.edit')->with(array('item'=>$item, 'category'=>$category));
回答9:
$oblast = Oblast::all();
$category = Category::where('slug', $catName)->first();
$availableProjects = $category->availableProjects;
return view('pages.business-area')->with(array('category'=>$category, 'availableProjects'=>$availableProjects, 'oblast'=>$oblast));
