Possible to perform login credential check without a page reload?
I tried to find the code for this function but I'm having a hard time. If it's possible, I would like to perform this check without a reload so that your email doesn't get removed if you type the wrong password.
It's not the biggest deal in the world so if it's like some complex thing to do I just won't worry about it. But if it's simple I'd love to implement this.
Please let me know if you have any tips! Thank you
Hey Alex!
Yes, you can use Laravel Livewire to implement a login form without a page reload. This will allow you to maintain the form state even if the user inputs incorrect credentials. Here is an example of how you could implement this:
- To create the Livewire component:
php artisan make:livewire LoginForm
This command will create two new files:
-
app/Http/Livewire/LoginForm.php- This is where you will put the component's PHP class. -
resources/views/livewire/login-form.blade.php- This is where you will put the component's HTML.
Once these files are created, you can add the code I provided in my previous message.
The LoginForm.php file would look something like this:
<?php
namespace App\Http\Livewire;
use Livewire\Component;
use Illuminate\Support\Facades\Auth;
class LoginForm extends Component
{
public $email;
public $password;
public $error;
protected $rules = [
'email' => 'required|email',
'password' => 'required',
];
public function login()
{
$this->validate();
if (!Auth::attempt(['email' => $this->email, 'password' => $this->password])) {
$this->error = 'The provided credentials are incorrect.';
return;
}
return redirect()->intended('dashboard');
}
public function render()
{
return view('livewire.login-form');
}
}
And the blade view would look something like this:
<div>
<form wire:submit.prevent="login">
<input type="email" wire:model="email" placeholder="Email">
@error('email') <span>{{ $message }}</span> @enderror
<input type="password" wire:model="password" placeholder="Password">
@error('password') <span>{{ $message }}</span> @enderror
@if($error)
<span>{{ $error }}</span>
@endif
<button type="submit">Log in</button>
</form>
</div>
This is just a simplified version, but you should be able to get the form classes from this file here and re-implement them as needed:
You can then include this Livewire component in the login blade view of the theme that you are using with:
@livewire('login-form')
Also, if you are not already using Livewire, you will have to include the scripts and styles with:
<head>
...
@livewireStyles
</head>
<body>
...
@livewireScripts
</body>
Let me know if you have any questions!
Wow, that is more than I was expecting, thank you for taking the time put all that in there. I'm gonna start messing with it now and see what I can get going with it. That is so helpful.
I also replied on that Paddle inline thread, I'm not sure if it notifies you for really old threads like that lol. It doesn't bump it to the top of the feed anymore so I figured it might not alert you at all.
Hey! No worries at all! Let me know how it goes and if you hit any blockers!
I've tried so many things but cannot seem to figure out what to do to fix this.
I'm getting this error
Unable to set component data. Public property [$email] not found on component: [login-form]
When I use the html you gave me for login form, at first I got the error about an undefined variable ($error) but I just gave up on that temporarily and commented out the code. When I do that is when I get the $email error above.
I figured for my previous login form, there was code elsewhere that designed the email input as $email, because I didn't see anything in the HTML that looked like it did that. But I wasn't able to find anything like that. I wasn't sure if I was just missing it, or there was something that this new livewire component needs that the other one didn't, and if that's the case then I really need help, lmao.
Thank you again, hopefully someone else uses all of your help in the future and this isn't only for just me 🙃
Nevermind, I'm an idiot. I pasted your LoginForm.php code into the file but didn't save it....
Christ what waste of time.
Okay jesus christ, I am having a hell of a time, I have another blocker...
So immediately whenever I save your code you gave me for LoginForm.php I get this error
Unable to find component: [login-form]
But then I can go back to my LoginForm.php and undo the changes and go back to the original code that's generated when I created LoginForm, and now the error doesn't go away. I save the file, refresh my page and the missing component error is still there. I ran the livewire:discover command and still nothing.
When I initially made it, before I pasted in your code, my page loads with the form, but then I get the $email error after a bit (which I now understand why, because my LoginForm doesn't have your code yet). But when I add your code, then it breaks. The weird thing is that undoing your code does not fix it, it just still errors until I delete the component entirely and do php artisan:make again.
Any tips?
okay, I got that figured out as well. Your code did not include the namespace information that was in the original LoginForm.php file, so I had to add that in there. Once I did everything was good.
Just in case anyone sees this and has a similar issue, I had to add this line back to the top of my LoginForm.php right under the <?php
namespace App\Http\Livewire;
Sorry for all the unnecessary reading, I think I'm all good :)
