laravel-5 passing variable to JavaScript

Question

is there any ways that JavaScript can get the variable from compact controller Laravel-5.

Example: I have the code below:

   $langs = Language::all()         


        

Answer 1

Standard PHP objects

The best way to provide PHP variables to JavaScript is json_encode. When using Blade you can do it like following:

• Displaying unescaped data - Laravel docs
• json_encode - PHP docs

There is also a Blade directive for decoding to JSON. I'm not sure since which version of Laravel but in 5.5 it is available. Use it like following:

• Blade Templates - Laravel 5.5 docs

Jsonable's

When using Laravel objects e.g. Collection or Model you should use the ->toJson() method. All those classes that implements the \Illuminate\Contracts\Support\Jsonable interface supports this method call. The call returns automatically JSON.

When using Model class you can define the $hidden property inside the class and those will be filtered in JSON. The $hidden property, as its name describs, hides sensitive content. So this mechanism is the best for me. Do it like following:

class User extends Model
{
    /* ... */

    protected $hidden = [
        'password', 'ip_address' /* , ... */
    ];

    /* ... */
}

And somewhere in your view
