The image must be an image, Laravel validation error

Question

I'm trying to upload an image on a form register, but when I submit this form, I receive this error "The image must be an image.". I already changed the model to accept all image extensions and tried to add "enctype="multipart/form-data" " on my form, but it didn't work.
How can I solve this problem? I need this image upload.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Foundation\Auth\User;
use Illuminate\Foundation\Livros;

class Livro extends Model
{
    use HasFactory;
    
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'livro',
        'users_id',
        'namel',
        'autor',
        'editora',
        'categoria',
        'classificação',
        'descricao',
        'image'=>'required|image|mimes:jpeg,jpg,png,bmp,gif,svg',

    ];

}

Controller

{
        return Validator::make($request, [

        $user = Auth::user()->id;
        $data = $request->all();

        if($request->file('image')->isValid()){

           $image = $request->image->store('livros');
           $data['image'] = $image;
        }

        
        Livro::create([

            'image'=>$request['image'],
        ]);
        return view('livros/cadastro');

        
    }

Answer 1

This is how the problem got solved for me!

1. Make Sure you have added

   enctype="multipart/form-data"

2. Input Type should be file

   <input type="file" name="image">

then In the validation

'image' => 'file|mimes:jpg,jpeg,png,gif|max:1024',

Answer 2

Your enctype=”multipart/form-data” is not correctly set, it is using strange " (dobule quotes), see they are like ” instead of ", so maybe you do not have enctype set, hence no file is being sent...
