I need to pass my data from the url and it works in the console log, but something happened to the view, it does not render the variable and the view loads just the footer, can anyone help me out please?
web routes:
Route::view('/aplicacion', 'application.visa-americana');
Route::get('/aplicacion/{id}', VisaUsaComponent::class);
layout:
#extends('layouts.app')
#section('content')
{{-- livewire interactions --}}
#livewire('applications.visa-usa-component')
#stop
Component:
use App\Models\User;
use Livewire\Component;
class VisaUsaComponent extends Component
{
public $post;
public function mount($id)
{
$this->post = User::findOrFail($id);
}
public function render()
{
return view('livewire.applications.visa-usa-component');
}
}
View:
<div>
{{ $post->name }}
</div>
try this:
public function render()
{
return view('livewire.applications.visa-usa-component')->layout('your layout address')->section('content');
}
Livewire use {{$slot}} for render and app.blade.php for layout, if you want change them, you must pass to render function
don't forget use #livewireScripts and #livewireStyles in app.layout.php

hi I have created a new default index view but it not loading its content and showing the blank page,,, my file structure https://ibb.co/wW337xS
index blade:
#extends('layouts.frontLayout.front_design')
#section('content')
<!--html here-->
#endsection
controller:
<?php
namespace App\Http\Controllers;
use App\Index;
use Illuminate\Http\Request;
class IndexController extends Controller
{
public function index()
{
return view('index');
}
route:
Route::resource('/','IndexController');
Its problem is occured, becouse you send user to the view with name of 'index', it means that there is a blade page in the view folder of your resource, but as i see in your structure, the index.blade.php is in this address: layouts.index. then you can refactor your controller:
public function index()
{
return view('layouts.index');
}
wrong
Route::resource('/','IndexController');
right
Route::get('/', 'IndexController#index');
I have two tables in my database, an Articles table and a Users table. An Article is posted by a user and a foreign key exists called 'created_by' referring to the 'user_id' field in the Users table.
My Laravel models are as follows:
User model
class User extends Model
{
use Notifiable;
protected $primaryKey = 'user_id';
public function articles()
{
return $this->hasMany('App\Article', 'created_by', 'user_id');
}
}
Article Model
class Article extends Model
{
protected $primaryKey = 'article_id';
public function user()
{
return $this->belongsTo('App\User', 'created_by' 'user_id');
}
}
I have a view dashboard which displays all the articles and the name of the person who posted it and their image.
Dashboard Controller
<?php
namespace App\Http\Controllers;
use App\User;
use App\Article;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class DashboardController extends Controller
{
public function index (Request $request)
{
if($request->session()->get('username')) {
$articles = Article::all();
return view('dashboard', compact('articles'));
}
else
return redirect('login');
}
}
And finally the section of my view I'm getting the 'Trying to get property of non-object' error for.
#foreach($articles as $article)
<div class="row">
<div class="col-lg-1"></div>
<div class="col-lg-9">
<div class="panel panel-info">
<div class="panel-heading">
<h3 class="panel-title">{{ $article->title }} </h3>
</div>
<div class="panel-body">
<p>
{{ $article->content }}
<br><br> - {{ $article->user->first_name }}
</p>
</div>
</div>
</div>
<div class="col-lg-1"><center><br><br>
<img src="{{ asset('images/people/$article->user->image') }}" class="img-circle" alt="Person"></center>
</div>
</div><br><br>
#endforeach
It seems to be the $article->user->first_name that I am having trouble with. If I type $article->user alone, the page will load but nothing appears in that area.
Any ideas, I have been searching for solutions for the last two hours.
I think you need to specify that you want users to load with with the articles, like $articles = Article::with('user')->all();
Drop a dd($articles) right before the return statement and you'll see what you're actually dealing with.
$articles = Article::with('user')->get();
Edit
Try to check also if $article->user is null in the view because if there is no user assigned for an article then you will get "trying to get property of non object" error
so give an extra check when you access user's data.
{{ $article->user !== null ? $article->user->first_name : 'User Not Found' }}
Do this for user photo also
Please edit your controller, pls mark as answered thx.
<?php
namespace App\Http\Controllers;
use App\User;
use App\Article;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class DashboardController extends Controller
{
public function index (Request $request, Article $articles)
{
if($request->session()->get('username')) {
return view('dashboard')->with('articles', $articles->all() );
}
else
return redirect('login');
}
}
I'm starting to use Laravel 5.1 from 4.2 and I have a question about the definition of layouts in the controller.
In 4.2 I have this:
private $layout = 'layouts.master';
public function showWelcome()
{
$this->layout->content = View::make('home');
}
When the view is loaded, the "Home" view will appear in the #yield('section') of "master.blade.php" in the layouts folder.
I searched for how to use this in 5.1 and I see that the assignment of the layout.masters has been removed, but I can't see the new usage anywhere.
Now in 5.1 I have:
namespace App\Http\Controllers;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use View;
class HomeController extends BaseController
{
public function showWelcome()
{
return view('home');
}
}
How can I say to the showWelcome() function that it has to yield the content with the view?
In Laravel 5.1 you can extend master layout in blade files writing at the top #extends('layouts.master') . From Laravel 5.1 Documentation
<!-- Stored in resources/views/child.blade.php -->
#extends('layouts.master')
#section('title', 'Page Title')
#section('sidebar')
#parent
<p>This is appended to the master sidebar.</p>
#endsection
#section('content')
<p>This is my body content.</p>
#endsection
Struggling to figure out how to achieve this. I want a login/registerform on same page when using tank_auth in CodeIgniter.
I was thinking of having something like this in my members controller (which extends My_Controller which extends Auth).
class Members extends My_Controller (
public function login()
{
//Already loggedin, do nothing
if ($this->tank_auth->is_logged_in()) {
return;
}
$this->view_data['login_by_username'] = true;
$this->view_data['login_by_email'] = false;
$this->view_data['show_captcha'] = false;
$this->view_data['login_form'] = $this->load->view('auth/login_form', $this->view_data, TRUE);
$this->view_data['register_form'] = $this->load->view('auth/register_form', $this->view_data, TRUE);
$this->v('members/login_register'); //In this view $login_form and $register_form is rendered
}
}
When I go to that page (localhost/members/login) the members/login-view is shown as expected, but in the action of the form for loginform it says:
http://localhost/members/login
Therefore when I click "Login-button" then it just calls members/login and that's not what I want. I want the action to be auth/login, but I still want to use my own template.
I hope you guys understand what I mean.... Please tell me if I'm doing anything wrong/thinking of this incorrectly.
UPATE:
In the actual template (members/login_register) it looks like this:
<div class="column">
<?php echo $login_form;?>
</div>
<div class="column>
<?php echo $register_form;?>
</div>
Maybe what I want to achieve is not possible?
Master View
You should use a Master view as a wrapper for your content.
That way you can easily pass in partial views(although not required)
However it will keep things neat. It also allows for easier control over
Admin/User Dashboards and your frontend.
Main Controller
class MY_Controller extends CI_Controller
{
public $template;
public function __construct()
{
$this->template = "master/template"; //views/master/template
}
}
To change it for an admin template(as an example of flexibility) you simply need to change it
the variable in the __constructor
class Admin_Controller extends MY_Controller
{
public function __construct()
{
$this->template = "master/admin/template"; //views/master/admin/template
}
}
Partial View(s)
Partial views can be used directly in other views.
You don't need a controller to call them.
These views are just stored in the buffer when they are
loaded by the loader class $this->load->view('', '', true)
A common approach is to create a folder inside /views called "partials".
This is where you would keep all you re-usable views(such as forms/widgets).
The Views(/views/partials/login_form)
<div>
<?php echo form_open('members/login', array('id'=>'login-form'))
</div>
The Views(/views/partials/signup_form)
<div>
<?php echo form_open('members/signup', array('id'=>'signup-form'))
</div>
The Views(members/index)
You can then combine the views
<div class="signup-form">
<?php echo $this->load->view('partials/signup_form')
</div>
<div class="login-form">
<?php echo $this->load->view('partials/login_form')
</div>
Login / Signup
In your members class you can create one method to show
the register/login form and then create methods to handle each of them individually.
class Members extends MY_Controller
{
public function index()
{
return $this->load->view('members/login_register');
}
public function login()
{
if(!$this->form_validation->run()){
return $this->index();
}
// form validation passed Ask Tank Auth
// to log the user in
$tank->auth->login();
}
public function signup()
{
if(!$this->form_validation->run()){
return $this->index();
}
// form validation passed Ask Tank Auth
// to register
$tank->auth->register();
}
}
Heres the controller:
class HomeController extends BaseController {
public function index() {
return View::make('home', array('username' => 'Vaughan'));
}
}
Here the home blade view:
{{ $username }}
Yet the view is outputting exactly this:
{{ $username }}
The variable is not being rendered. Could this be something to do with Apache or PHP?
You need to name your view with blade extension:
home.blade.php
That's all.
