getting an Undefined index: id in submitting a form - php

Question

I got this error yesterday and I thought I fixed it. I am submitting an update form.
#extends('layouts.master')
#section('content')
<form action="{{url('/student/update')}}" method="POST" role="form">
{{ csrf_field() }}
{{method_field('PUT')}}
<legend>Create a Student</legend>
<input type="hidden" name="id" class="form-control" value="{{$student->id}}">
<div class="form-group">
<label for="">Name</label>
<input type="text" class="form-control" name="name" value="{{$student->name }}"required="required">
</div>
<div class="form-group">
<label for="">Address</label>
<input type="text" class="form-control" name="address" value="{{$student->address }}" required="required">
</div>
<div class="form-group">
<label for="">Phone</label>
<input type="text" class="form-control" name="phone" value="{{$student->phone }}" required="required">
</div>
<div class="form-group">
<label for="">Career</label>
<select name="career" class="form-control" required="required">
<option>Select a Career</option>
<option value="math"{{$student->career == 'math' ? 'selected' : ''}}>Math</option>
<option value="physics"{{$student->career == 'physics' ? 'selected' : ''}}>Physics</option>
<option value="engineering"{{$student->career == '' ? 'engineering' : ''}}>Engineering</option>
</select>
</div>
<button type="submit" class="btn btn-primary">Update Student</button>
</form>
#endsection
The error says that it relates to my ClientController on line 82.
protected function updateOneStudent($parameters)
{
$studentId = $parameters['id'];
return $this-
>performPutRequest("https://lumenapi.juandmegon.com/students/{$studentId}",
$parameters);
}
It was the same function that was giving me the problem yesterday. The problem was that I was not calling a function. The performPutRequest function is like this.
protected function performPutRequest($url, $parameters = [])
{
$contents = $this->performAuthorizeRequest('PUT', $url, $parameters);
$decodedContents = json_decode($contents);
return $decodedContents->data;
}
Any help would be appreciated.

Thanks beginner for point me in the right direction. I had the code below.
protected function updateOneStudent($parameters)
{
$studentId = $parameters['id';
return $this->performPutRequest("https://lumenapi.juandmegon.com/students/{$studentId}", $parameters);
}
I missed a bracket from the id. So it should look like this
protected function updateOneStudent($parameters)
{
$studentId = $parameters['id'];
return $this->performPutRequest("https://lumenapi.juandmegon.com/students/{$studentId}", $parameters);
}
