404 NOT FOUND EDIT AND UPDATE LARAVEL 6 - php

Question

while passing variable in URL to edit and update a form it's returning only 404 not found , the tutorials did not help me , so this is my code :
controller : rendezv.php
public function editer ($id) {
$rdv= rendezvous::findOrFail('id');
return view ('/edit', ['modifier'=>$rdv]);
}
public function update(Request $request ,$id)
{
$this->validate($request, [
'email' => 'required' ,
'tel' => 'required'
]);
//modifier rendez vous
$editer=rendezvous::findOrFail('id');
$editer->Email = $request->input('email');
$editer->tel = $request->input('tel');
$editer-> save();
return redirect('/index');
}
and this this edit.blade.php
<form action="/update/{{$modifier->id}}" method="post" role="form" data-aos="fade-up">
#csrf
<input type="hidden" name="_method" value="PATCH" />
<input placeholder="{{$modifier->Email}}" type="email" class="form-control" name="email" id="email" data-msg="Please enter your name " />
<input placeholder="{{$modifier->Numéro_de_téléphone}} " type="text" class="form-control" name="tel" id="subject" data-rule="minlen:8" data-msg="Please enter at least 8 numbers" /> </i>
<div id="buttons">
<button type="submit" class="btn btn-primary"> modifier </button>
</div>
</form>
and finally route :
Route::get('/rendezvous_{ID}', 'doctor#rdv');
Route::post('/rdv','rendezv#rdv');
Route::post('/bienvenu','doctor#authentification')->name('aziz');
Route::get('/edit/{id}','rendezv#editer');
need yr help guys , and thank you

Answer 1

Please add the route for update
Route::patch('/update/{id}','rendezv#update');
You get 404 for both edit and update for findOrFail() method. You are passing string 'id' instead of $id.
In editer method please replace
$rdv= rendezvous::findOrFail('id');
with
$rdv= rendezvous::findOrFail($id);
In update method please replace
$editer=rendezvous::findOrFail('id');
With
$editer=rendezvous::findOrFail($id);
Furthermore, findOrFail() method will return 404 if no data is found with the given $id

Answer 2

You route /update/{{$modifier->id}} doesn't exist, you need to declare it in you router file:
Route::post('/update/{id}','rendezv#update');

Answer 3

Take a look at the Resource Controllers
What you are looking for is a Route::post('/edit/{id}','rendezv#update'); or put or patch

Answer 4

You are missing a post route:
Route::post('/edit/{id}','rendezv#update');
