Undefined offset: 1 in laravel 8

Question

Im currently learning to do sign in and sign up in laravel8 by referring some tutorials. But after sign up im getting this Undefined offset: 1 message.

Error line that showing is

$iteratee = trim($matches[1]);

This is my route file(web.php)

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\UserController;


Route::get('/signup',[
    'uses' =>'App\Http\Controllers\UserController@getSignup',
    'as'=>'user.signup'
   
]);

Route::post('/signup',[
    'uses' =>'App\Http\Controllers\UserController@getSignup',
    'as'=>'user.signup'
   
]);

And this is the signup page register part

  <header class="masthead"  >
            <div class="container">
                <div class="masthead-subheading"></div>
                <div class="masthead-heading text-uppercase"></div>
                <div class="container">

                    <div class="card bg-light">
                        <article class="card-body mx-auto" style="max-width: 400px;">
                            <h4 class="card-title mt-3 text-center">Create Account</h4>
                         

                            <p class="text-center">Get started with your free account</p>
                            @if(count($errors) > 0)
                            <div class="alert alert-danger">

                            @foreach($errors->all()as $error)
                            <p>{{$error}}</p>
                            @endforeach
                            </div>
                            @endif
                          
                            <form  action="{{ route('user.signup')}}">

UserController

class UserController extends Controller

    {
         return view('user.signup');
 
    }
    public function postSignup(Request $request)
    {
         $this->validate($request,[
 
             'email'=> 'email|required|unique:users',
             'password'=>'required|min:4' 
 
         ]);
 
 
         $user= new User([
 
            'email'=>$request-> input('email'),
            'password'=> bcrypt($request-> input('password'))
 
         ]);
 
         $user-->save();
         return redirect()->route('shop.index');
 
     }
 
}

Please teach me a way to solve this.Thank you

`$matches`, which is an array (maybe? You don't show how you define it), doesn't have an index `1`, so you can't do `$matches[1]`. Is there something unclear about that error message? — Tim Lewis, Nov 19 '20 at 16:43
I dont get it.never used something called {$matches} before.But it is the code line showing in laravel with Undefined offset: 1 error. Is it something wrong in my singin page coding? — tuneKawaii UwU, Nov 19 '20 at 16:49
Did you write this code? What do you mean "never used something called `$matches` before"... — Tim Lewis, Nov 19 '20 at 16:50
I think it is an inbuilt code that comes with laravel. Only thing i did is creating UserController,User model and signup.blade.php page. — tuneKawaii UwU, Nov 19 '20 at 16:53
This looks wrong: `Route::post('/signup', ['uses' => 'App\Http\Controllers\UserController@getSignup', ...`, why would the `POST` route use `getSignup`? Should that be `postSignup`? Also, `$user-->save();` is a syntax error. You have 2 `--`, should be `$user->save();` — Tim Lewis, Nov 19 '20 at 16:57
@TimLewis Thank you so much for showing me that.I fixed the things you said but the error message keeps coming :( — tuneKawaii UwU, Nov 19 '20 at 17:08
`@foreach($errors->all()as $error)` is the cause of that error; there's no space between `()` and `as`, so the `@foreach()` directive fails (as shown in the answer below). This is a prime example of why indentation and spacing is so important when coding. Please try to be consistent and follow conventions; spaces before and after `=>` for arrays, no spaces around `->` for object access, etc etc. Consider using an IDE (VSCode, SublimeText, etc.) that has a linter/syntax highlighter available to avoid these edge issues. — Tim Lewis, Nov 19 '20 at 17:19
@TimLewis corrected that as you guys said but error is same.Is something wrong how i used the loop there — tuneKawaii UwU, Nov 19 '20 at 17:38
Check all of your `@` directives; it might be in a different one, in a view that is extended by your current view. You're not really showing us enough of your code for us to say that the `@foreach()` is the **only** one that could have this issue. — Tim Lewis, Nov 19 '20 at 17:45

You should add a space in the @foreach between the pieces:

@foreach($errors->all()as $error)

Should be:

@foreach($errors->all() as $error)

The Blade compiler parses the expression passed to this directive and does a preg_match on it to get the pieces of the expression as this directive does more than just creating a foreach loop. Here is the match on the expression:

preg_match('/\( *(.*) +as *(.*)\)$/is', $expression, $matches);

$iteratee = trim($matches[1]);

the only place in the entire code base where `$iteratee = trim($matches[1]);` exists is in the Blade Compiler `@compileForelse` and `@compileForeach` (which comes from the `CompilesLoops` trait) – lagbox Nov 19 '20 at 17:22
Corrected the @foreach as you said but error keeps coming.Is it something wrong how i used the loop in my blade file – tuneKawaii UwU Nov 19 '20 at 17:33

@tuneKawaiiUwU The view could be cached, try clearing it out. – miken32 Nov 19 '20 at 18:47
