I am new to laravel and seem to have issues with authentication. I created a custom login page and wanted to use the auth() function to allow registration and login. Here is my login controller it shows the connection to the blade file the registration has no issues but the login is giving me problems.
When I dd() it returns an empty array, the database seems fine proved by registration.
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use auth;
class LoginController extends Controller
{
public function index()
{
return view('auth.login');
}
public function store(Request $request)
{
if(!auth()->attempt($request->only('email','password'))) {
return back()->with('status','Invalid login Details');
}
dd($request->only('email','password'));
return redirect()->route('dashboard');
}
}
```
below is the blade file responsible for submitting the form to authenticate the user I suspected the session but without it I cant check
```

```
You forgot to add a name to your inputs try:
<input type="password" name="password" placeholder="Password" required pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,}" title="Must contain at least one number and one uppercase and lowercase letter, and at least 8 or more characters"/>
And
<input type="text" name="email" placeholder="User Email" required />
You can't run auth without adding a name use this code in the input tag instead.
<input type="password" name="password" placeholder="Password"
required pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,}"
title="Must contain at least one number and one uppercase and lowercase
letter, and at least 8 or more characters"/>
<input type="text" name="email" placeholder="User Email" required />

saying error : Caused by: org.springframework.expression.spel.SpelEvaluationException: EL1007E: Property or field 'userName' cannot be found on null
Login page is not ruuning because LoginData is empty at begining
You haven't exactly specified which of the 2 pages are causing the issue, but I'm going to guess that it is the first one.
I would first try replacing the th:value tag with th:field in the username input:
<input
type="text"
name="userName"
class="form-control"
th:field="*{userName}"
id="exampleInputEmail1"
aria-describedby="emailHelp">
Since you have already defined the loginData object within the form tag:
th:object="${loginData}
The next input tag could also cause some issues, I'm guessing that this should accept the user's password:
<input
type="email"
name="email"
th:value="${loginData}"
class="form-control"
id="exampleInputPassword1">
You would want to update it to something like:
<input
type="password"
th:field="*{password}"
class="form-control"
id="exampleInputPassword1">
The exception tells you that there is no model attribute with the name loginData. looking at the controller code after this that can be confirmed as you are adding a model attribute with name login not loginData m.addAttribute("login", new LoginData());
Also I'm not usre why you define a loginData variable in your controller, check if it's non null and than don't use it but create a new one
LoginData loginData = new LoginData();
if(loginData != null ) {
m.addAttribute("login", new LoginData());
System.out.println("YAY");
}
I'm creating an Object in GET method and initialize it with nulls. Then I set some values and send it to the POST method, but after this process all of values that I set earlier are nulls. How could I repair it? I've tried to use hidden fields, but it didn't help.

I am new to Vue.js. I am trying to make a form dynamic (only a certain part of the form dynamic.). A user can have multiple guarantors. So I made the Guarantor form Dynamic with VueJS. When I submit the form and return the request, I see only the last array. Its always the last array, all others are lost.
This is the blade file.
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">

</head>
<body>
<div id="app">
<div class="container pt-5">
<form action="{{ route('submit.store')}}" method="post">
#csrf
<div class="card-body">
<h4 class="card-title">User Detail</h4>
<input type="text" class="form-control mb-1" name="user_name" id="user_name" placeholder="Name" />
<input type="email" class="form-control mb-1" name="user_email" id="user_email"
placeholder="Email" />
<textarea name="about" class="form-control" id="about" cols="30" rows="10"
placeholder="About"></textarea>
</div>
<dynamic-form></dynamic-form>
</form>
</div>
</div>
<script src="{{ asset('js/app.js') }}"></script>
</body>
</html>
And this is how the VueComponent looks.
<template>
<div>
<button class="btn btn-success mb-3" #click.prevent="addNewUser">Add User</button>
<div class="card mb-3" v-for="(user, index) in users" :key="index">
<div class="card-body">
<span class="float-right" style="cursor:pointer" #click.prevent="removeForm(index)" >X</span>
<h4 class="card-title">Guarantor No: {{ index }}</h4>
<input type="text" class="form-control mb-1" name="name" id="name" placeholder="Name" v-model="user.name" />
<input type="email" class="form-control mb-1" name="email" id="email" placeholder="Email" v-model="user.email"/>
<textarea name="about" class="form-control" id="about" cols="30" rows="10" placeholder="About" v-model="user.about"></textarea>
</div>
</div>
<input type="submit" class="btn btn-primary" value="submit">
</div>
</template>
<script>
export default {
name: 'dynamic-form',
data() {
return{
users: [
{
name: '',
email: '',
about: ''
}
]
}
},
methods: {
addNewUser: function() {
this.users.push({
name: '',
email: '',
about: ''
});
},
removeForm: function(index) {
this.users.splice(index, 1);
}
}
}
</script>
How can I tackle this problem?
In PHP, values with the same name attribute value will get overwritten. (See the "How do I get all the results from a select multiple HTML tag?" section here).
You can create arrays of values by adding a bracket to the name. For example, if you made the name of the "name" input name[], name will be an array of names in PHP.
In your case, you could use this format: name="guarantors[][name]". That way you will get an array in PHP under the key guarantors (e.g. $request->guarantors) and each of the values in guarantors will be an array with the values name, email, etc.
Here is my login form with hidden field name "callbackUrl". How can i get the value of this hidden field in controller? User's attributes are username and password. callbackUrl is not.

<input name="password" type="password" class="form-control" placeholder="Password"/>
<input name="callbackUrl" type= "hidden" id="callbackUrl">
<h2>${error}</h2>
<br/>
<button class="btn btn-lg btn-primary btn-block" type="submit">Log In</button>
<h4 class="text-center">Create an account</h4>
</form>
</body>
<script>
var url_string = window.location.href; //window.location.href
var url = new URL(url_string);
var c = url.searchParams.get("callbackUrl");
console.log(c);
document.getElementById("callbackUrl").value = c;
</script>
</html>
add #RequestParam("callbackUrl") String callBackUrl to the method in your controller.
Like so:
public String myMethod(#RequestParam("callbackUrl") String callBackUrl, …) {
System.out.println(callBackUrl); //this will print the url to console
}
