How can I pass value from blade into controller in Laravel? [duplicate] - php

Question

Im passing data to my blade view with return View::make('blog', $posts); and in my blade view I'm trying to run an #foreach ($posts as $post) I end up with an error saying that $posts isn't defined.
My question is how would the $posts array be called?

Answer 1

You can pass data to the view using the with method.
return View::make('blog')->with('posts', $posts);

Answer 2

As of Laravel 5, the View::make() facade method from the 2013 accepted answer has been deprecated. Passing data to the view is now done using the view() helper function like this:
return view("blog", ["posts"=>$posts]);
Or, the same thing:
return view("blog", compact("posts"));
This can be combined with the with() method if desired:
return view("blog", compact("posts"))->with("message", "Comment posted");
Documentation is available here.

Answer 3

If you want to pass just one variable to view, you may use
In Controller
return view('blog')->withTitle('Laravel Magic method.');
In view
<div>
Post title is {{$title}}.
</div>
If you want to pass multiple variables to view, you may use
In Controller
return view('blog')->withTitle('Laravel magic method')->withAuthor('Mister Tandon');
In view
<div>
Post title is {{$title}}.Author Name is {{$author}}
</div>

Answer 4

You can also pass an array as the second argument after the view template name, instead of stringing together a bunch of ->with() methods.
return View::make('blog', array('posts' => $posts));
Or, if you're using PHP 5.4 or better you can use the much nicer "short" array syntax:
return View::make('blog', ['posts' => $posts]);
This is useful if you want to compute the array elsewhere. For instance if you have a bunch of variables that every controller needs to pass to the view, and you want to combine this with an array of variables that is unique to each particular controller (using array_merge, for instance), you might compute $variables (which contains an array!):
return View::make('blog', $variables);
(I did this off the top of my head: let me know if a syntax error slipped in...)

Tips1:
Using With(), This is a best practice
return view('about')->withName('Author Willson')->withJob('Writer');
return View::make('home')->with(compact('about'))
return View::make('home')->with('comments', $comments);
Tips2:
Using compact()
return view(about, compact('post1','post2'));
Tips3:
Using Second Parameters:
return view("about", ["comments"=>$posts]);

Answer 6

controller:
use App\your_model_name;
funtion index()
{
$post = your_model_name::all();
return view('index')->with('this_will_be_used_as_variable_in_views',$post);
}
index:
<h1> posts</h1>
#if(count($this_will_be_used_as_variable_in_views)>0)
#foreach($this_will_be_used_as_variable_in_views as $any_variable)
<ul>
<p> {{$any_variable->enter_table_field}} </p>
<p> {{$any_variable->created_at}} </p>
</ul>
#endforeach
#else
<p> empty </p>
#endif
Hope this helps! :)

use TCG\Voyager\Models\Jobtype;
class FormController extends Controller
{
public function index()
{
$category = Jobtype::all();
return view('contact', compact('category'));
}
}
use your model
assign it to a variabel
pass the object to the view
Here is an example:

Answer 8

You can also do the same thing in another way,
If you are using PHP 5.5 or latest one then you can do it as follow,
Controller:
return view(index, compact('data1','data2')); //as many as you want to pass
View:
<div>
You can access {{$data1}}. [if it is variable]
</div>
#foreach($data1 as $d1)
<div>
You can access {{$d1}}. [if it is array]
</div>
#endforeach
Same way you can access all variable that you have passed in compact function.
Hope it helps :)

Answer 9

You can also do like this
$arr_view_data['var1'] = $value1;
$arr_view_data['var2'] = $value2;
$arr_view_data['var3'] = $value3;
return view('your_viewname_here',$arr_view_data);
And you access this variable to view as $var1,$var2,$var3

Answer 10

You can pass data to the view using the with method.
return view('greeting', ['name' => 'James']);

Answer 11

You can pass your table data to view using compact.
$users = RoleModel::get();
return view('super-admin',compact('users'));

Answer 12

You can also write for passing multiple data from your controller to a view
return \View::make('myHome')
->with(compact('project'))
->with(['hello'=>$hello])
->with(['hello2'=>$hello2])
->with(['hello3'=>$hello3]);

Answer 13

OK all the answers tell you how to pass data to the view but no one explains how to read it in the view .
if you use :
//Routes/web.php
...
Route::get('/user', function () {
return view('profile', [
'variable1' => 'value1' ,
'variable2'=> 'value2' , // add as much as you want
]);
});
To read these variables use in your views (in this example it's profile.blade.php file):
#if($variable1)
<p> variable1 = {{ $variable1 }}</p>
#endif
Laravel does all the necessary work and creates $variable1 for you .

Answer 14

For example, you have an array with your data.
$array1 = $data;
$array2 = $data;
From your controller you can pass this variable using compact. You can pass as many array as you want.
return view('data.index',compact('array1','array2'));
Here data is a folder in view and index is the file with extension index.blade.php
In view you can call the arrays like this
#foreach ($array1 as $something)
// some operation
#endforeach

Answer 15

For any one thinking it is really tedious in the case where you have tons of variables to pass to a view or you want the variables to be accessible to many views at the same, here is another way
In the controller, you define the variables you want to pass as global and you attribute the values to these variables.
Example global $variable; $variable = 1;
And now in the view, at the top, simply do
<?php global $variable;?>
Then you can now call your variable from any where in the view for example
{{$variable}}
hope this helps someone.
