error : Undefined index: name in Laravel blade template

Question

I have a login form in my laravel project and send the user login data in my controller method using ajax. While users successfully logged in I kept the user_name in session $_SESSION['name] . But when I try to show that $_SESSION['name] in my blade template view it gives error

local.ERROR: Undefined index: name

Here is my login controller method

public function signin(LoginFormValidation $request)
{
    $user_password = $request->password;

    $data = User::where('email','=',$request->email)->first();

    if(Hash::check($user_password, optional($data)->password))
    {
        $_SESSION['name'] = $data->name;

        echo "success";
    }
    else
    {
        echo "no";
    }
}

Here is my blade template view

<ul class="cd-main-nav__list js-signin-modal-trigger">

    <li><a class="cd-main-nav__item cd-main-nav__item--signup" href="#0">{{ $_SESSION['name'] }}</a></li>

</ul>

Why the username isn't stored in my session or if it stored why gives the error ?

Answer 1

Use laravel session helper function

Controller

public function signin(LoginFormValidation $request)
{
    $user_password = $request->password;

    $data = User::where('email','=',$request->email)->first();

    if(Hash::check($user_password, optional($data)->password))
    {
        session()->put('name', $data->name);

        echo "success";
    }
    else
    {
        echo "no";
    }
}

Blade

<ul class="cd-main-nav__list js-signin-modal-trigger">

    <li><a class="cd-main-nav__item cd-main-nav__item--signup" href="#0">{{ session()->get('name') }}</a></li>

</ul>

Answer 2

you forgot to start the session.

session_start();

Recommended way for versions of PHP >= 5.4.0

 if (session_status() == PHP_SESSION_NONE) {
     session_start();
 }
