How to make a global variable for all blade laravel

Good Peoples.

I have an issue with my project.

In the layout blade, I need to fetch some data from the database. But I cannot pass variables as there has no route for the layout blade. It’s just a master blade.

Is there any way to make a global variable and use it all blade?

Thanks for the valuable replies.

Answer

to have global functions or variables there are different ways in my opinion, the easiest way is:

make a helper php file to restore global functions and vars, in this way you load this file in composer.json and you can call that everywhere you want.

I created Functions.php in App/Helpers directory to restore my global vars and functions.

after that declare the file in composer.json: “autoload”, inside it if there is not “files(array)” add it and set the path to your file. in my example, it is “app/Helpers/Functions.php”.

"autoload": {
        "psr-4": {
            "App\": "app/",
            "Database\Factories\": "database/factories/",
            "Database\Seeders\": "database/seeders/"
        },
        "files": [
            "app/Helpers/Functions.php"
        ]
    },

finally, rerun the

php artisan serve

for accessing a variable in your blade, I’m not sure you can do it or not (I tried but it returns undefined variable).

you can do:

// in your helper file
myFunc() {
    $myVar = 'value';
    return $myVar;
}

// in your blade
{{ myFunc() }}

or using classes:

// in your helper file
class myClass {
    protected $myVar = 'value';
    protected static $staticVar = 'value';

    public myFunc() {
        return $this->myVar;
    }

    public static staticFunc() {
        return myClass::$staticVar;
    }
}

// in your blade
{{ (new myClass())->myFunc() }}
// of static function
{{ myClass::staticFunc() }}

hope, it helps…
