Laravel detach wrong id - php

I'm building a micro ecommerce in laravel, and I've a problem with detaching an element added in the cart. I'll explain: For example, if I add 4 elements in the cart, when I click "remove element" on the last element I've added in the cart, the last element is not deleted, but vice versa is deleted the first one I've added.
This is my Controller file in laravel:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Computer;
use App\Smartphone;
class FrontController extends Controller
{
public function cart()
{
$computers = Computer::all();
$smartphones = Smartphone::all();
return view('cart',compact('computers', 'smartphones'));
}
public function computers()
{
$computers = Computer::all();
return view('computers',compact('computers'));
}
public function smartphones()
{
$smartphones = Smartphone::all();
return view('smartphones',compact('smartphones'));
}
public function addpc($id)
{
$user = Auth::user();
if(!$user)
return redirect('/login');
$user->computers()->attach($id);
return redirect(route('cart'));
}
public function removepc($id2)
{
$user = Auth::user();
if(!$user)
return redirect('/cart');
$user->computers()->detach($id2);
return redirect(route('cart'));
}
public function addsmartphone($id3)
{
$user = Auth::user();
if(!$user)
return redirect('/login');
$user->smartphones()->attach($id3);
return redirect(route('cart'));
}
public function removesmartphone($id4)
{
$user = Auth::user();
if(!$user)
return redirect('/cart');
$user->smartphones()->detach($id4);
return redirect(route('cart'));
}
}
This is my web.php file:
Route::get('/computers', 'FrontController#computers')->name('computers');
Route::post('/computers{id}/addpc','FrontController#addpc')->name('computers.addpc');
Route::post('/computers{id2}/removepc','FrontController#removepc')->name('computers.removepc');
Route::get('/smartphones', 'FrontController#smartphones')->name('smartphones');
Route::post('/smartphones{id3}/addsmartphone','FrontController#addsmartphone')->name('smartphones.addsmartphone');
Route::post('/smartphones{id4}/removesmartphone','FrontController#removesmartphone')->name('smartphones.removesmartphone');
This is my smartphones.blade.php file:
#extends('layouts.app')
#section('content')
<main class="container">
<section class="row justify-content-center">
#foreach($smartphones as $smartphone)
<div class="col-12 col-md-5 my-5">

I hope I explained myself, thanks for help!

You need to close your forms , for every category there, inside the loop.

CRUD - Overview

I succeeded the step "create" barring the overview.
My recordings are saved on PhpMyAdmin but not on my page index.blade.php I don't understand why ? I made several refreshments even so.
Here is my file AdminController.php
class AdminController extends Controller
{
public function index(){
/*$devis = Devis::all()->sortByDesc("created_at");
return view('admin.home', compact('devis'));*/
$students = Student::first()->paginate(5);
return view('student.index', compact('students'))
->with('i', (request()->input('page',1)-1)*5);
}
public function create()
{
return view('student.create');
}
public function store(Request $request)
{
$request->validate([
'firstname' => 'required',
'lastname' => 'required'
]);
Student::create($request->all());
return redirect()->route('student.index')
->with('success', 'save');
}
}
In my folder VIEWS with another folder which is Student which has 2 files:
Index.blade.php
#extends('student.template.master')
#section('left_menu')
#include('student.template.left_menu', array('current' => 'home'))
#endsection
#section('content')

Do you have an idea please ? I am really stuck.
first() returns an instance of the class Student, you can't paginate on it. change
public function index(){
/*$devis = Devis::all()->sortByDesc("created_at");
return view('admin.home', compact('devis'));*/
$students = Student::first()->paginate(5);
return view('student.index', compact('students'))
->with('i', (request()->input('page',1)-1)*5);
}
to
public function index(){
/*$devis = Devis::all()->sortByDesc("created_at");
return view('admin.home', compact('devis'));*/
$students = Student::paginate(5);
return view('student.index', compact('students'))
->with('i', (request()->input('page',1)-1)*5);
}
In Laravel, when you use paginate(), it also comes with links() function. So all you needed to do was to pass the variable in the controller, as below:
public function index(){
$students = Student::get()->paginate(5);
return view('student.index', compact('students'));
}
Now, in index.blade.php, just reference the links() function:
{{ $students->links() }}

The first think that comes to my mind is that you are giving a variable named question to your view in your controller and you are trying to use $questions in your foreach when it must be $question as $q
The other thing is that you may want to pass all Questions rows you have to you view, it can be accomplished (this may not be the best solution) by editing your AppServiceProvider.php
You have to add this.
use View;
use App\Question;
public function boot()
{
//
View::share('questions',Question::all());
}
But if you do this, it will share the rows obtained with all your views.
hope this helps.

The way you are defining the relationship is wrong. I think this is OneToMany relationship. Like A Group has many users. Then you must define it like this
MODELS
Grouptable:
public function members(){
return $this->hasMany('App\Member','group_id'); // group_id represents the name of the foreign key. It is not neccessary if your foreign key is Grouptable_id, because Laravel automatically guess it unless the foreign key name is explicitly provided
}
Member:
public function groups(){
return $this->belongsTo('App\Grouptable','group_id');
}
To retrieve all members of a particular group say groupid 1:
$members = \App\Gouptable::find(1)->members;
CONTROLLER
Something seems to be wrong in your addmembers() function:
public function addmembers(Request $request){
$member=new Member();
$member->members=$request['addmember'];
$request->groups()->members()->save($member); //what is this groups()?
//You need to do something like this
$groupid = $request['groupid']; // send groupid as parameter from form
Grouptable::find($groupid)->members()->save($member);
return redirect()->back();
}

public function addmembers(Request $request){
$member=new Member();
$member->members=$request['addmember'];
$request->groups()->members()->save($member);
return redirect()->back();
}
should look more like
public function addmembers(Request $request){
$member=new Member();
$member->propertyX = $request->get('propertyX');
$member->propertyY = $request->get('propertyY');
$member->groups()->attach($group); // FOR MANY-TO-MANY (N-N) RELATION
$member->groups()->associate($group); // FOR ONE-TO-MANY (1-N) RELATION
$member->save();
return redirect()->back();
}
Depending on your migrations you should choose attach() or associate()

Problems while passing variable from controller to blade view

I have a model class
<?php
class CategoriaModificador extends Base
{
protected $table = 'categorias_modificadores';
public function restaurantes()
{
return $this->hasMany('CategoriaModificadorRestaurante', 'categorias_modificadores_id');
}
}
When I try to pass the variable to the blade view in my controller
public function show($id = 0)
{
if (!get_session_empresa()) {
return Redirect::route('empresa.logar')->with('message_error', 'Você precisa está logado');
}
$categoriaModificador = CategoriaModificador::where('empresas_id', (int)get_session_empresa()->id)
->where("id", (int)$id)
->first();
return View::make('frontend.' . $this->theme_base . '.categoria-modificador.show')
->with('categoriaModificador', $categoriaModificador);
}
I find this error

Thanks for posting the view. I think the problem is you're using $categoriaModificador->restaurantes[$i]->nome, but it seems you do not have nome in your $categoriaModificador->restaurantes collection.
Also, why are you using double dollar sign with $$categoriaModificador?
If you clearly look at your error, you will find your solution yourself. Undefined variable error means you are printing something in the view file that is not defined.
For general solution, you should check if the variable is defined previously or is passed to the view. This may helps other.
Thanks
