Undefined variable: user_id in Laravel view - php

Question

The Routes
Route::get('/adminContacts/{user_id}', 'AdminContactsController#index')->name('adminContacts.index')->middleware('is_admin');
Route::get('/adminContacts/{user_id}/create', 'AdminContactsController#create')->name('adminContacts.create')->middleware('is_admin');
adminContactController
public function index($user_id)
{
// Confirm User exists
User::findOrFail($user_id);
$filter = request('filter', NULL);
$contacts = NULL;
if ($filter == NULL)
$contacts = Contacts::query()->where('owner_id', $user_id)->sortable()->paginate(5);
else
$contacts = Contacts::query()->where('owner_id', $user_id)->where('name', 'like', '%'.$filter.'%')
->orWhere('number', 'like', '%'.$filter.'%')
->sortable()->paginate(5);
return view('adminContacts.index')->withContacts($contacts)->withUserId($user_id);
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create($user_id)
{
return view('adminContacts.create')->withUserId($user_id);
}
index.blade.php
<div class="container">
<h1 class="jumbotron">Sample Phone Book</h1>
Add Contact
</div>
<!--Search Field -->
<div class="container">
<form method="GET" action="{{ route('adminContacts.index') }}">
<input type="text" name='filter' class='input' placeholder='Search' value="{{ request('filter') }}">
#if (request('filter'))
<a class="btn btn-primary btn-sm" href="{{ route('adminContacts.index') }}">X</a>
#endif
</form>
</div>
<!-- Table -->
<div class="container">
<div class="row" >
<table class="table table-hover" id="contactsTable">
<thead>
<tr>
<th>#</th>
<th>#sortablelink('name', 'Contact Name')</th>
<th>#sortablelink('number', 'Phone Number')</th>
<th>
<button class="btn btn-primary btn-sm">Prepend</button>
</th>
</tr>
</thead>
<!--Loop through all the cutomers and output them on the table-->
#foreach($contacts as $contact)
<tbody>
<tr>
<td>{{ $contact->id }}</td>
<td>{{ $contact->name }}</td>
<td>{{ $contact->number }}</td>
<td>
View
</td>
</tr>
</tbody>
#endforeach
</table>
{!! $contacts->appends(\Request::except('page'))->render() !!}
</div>
</div>
The error is:
Undefined variable: user_id (View: D:\laragon\www\SampleContacts\resources\views\adminContacts\index.blade.php)
Am I missing something? The idea is to pass the $user_id to the adminContact.create form where i can use it to set
$contact->owner_id = $user_id;
so the entered contact apears under that users table.

Answer 1

I don't think you can pass variables into your view like you're doing now.
In your controller, try changing this line:
return view('adminContacts.index')->withContacts($contacts)->withUserId($user_id);
To this:
return view('adminContacts.index')->with('contacts', $contacts)->with('user_id', $user_id);

Answer 2

You could explicitly name the variable when passing it to the view, either this way
return view('adminContacts.index')->with('user_id', $user_id);
Or
return view('adminContract.index', compact('user_id'));
I'm not sure what the name of the variable becomes when passed to the view via withUserId, but I'm guessing this is the issue.

Found the problem.
#extends('layouts.app')
#section('content')
<div class="container">
<h1 class="jumbotron">Sample Phone Book</h1>
Add Contact
</div>
<!--Search Field -->
<div class="container">
<form method="GET" action="{{ route('adminContacts.index', $user_id) }}">
<input type="text" name='filter' class='input' placeholder='Search' value="{{ request('filter') }}">
#if (request('filter'))
<a class="btn btn-primary btn-sm" href="{{ route('adminContacts.index', $user_id) }}">X</a>
#endif
</form>
</div>
<!-- Table -->
<div class="container">
<div class="row" >
<table class="table table-hover" id="contactsTable">
<thead>
<tr>
<th>#</th>
<th>#sortablelink('name', 'Contact Name')</th>
<th>#sortablelink('number', 'Phone Number')</th>
<th>
<button class="btn btn-primary btn-sm">Prepend</button>
</th>
</tr>
</thead>
<!--Loop through all the cutomers and output them on the table-->
#foreach($contacts as $contact)
<tbody>
<tr>
<td>{{ $contact->id }}</td>
<td>{{ $contact->name }}</td>
<td>{{ $contact->number }}</td>
<td>
View
</td>
</tr>
</tbody>
#endforeach
</table>
{!! $contacts->appends(\Request::except('page'))->render() !!}
</div>
</div>
#endsection
Anywhere where there is a {{ route('adminContacts.index') }} it also needed the $user_id to be passed along with it because I'm also using it in the routes as '/adminContacts/{user_id}'
Thank you for all the help.
