Passing Parameters from one view to another Laravel - php

Question

I'm new with Laravel and there are some concepts that I don't understand very well. I really need your help on this because I've read many many pages, tutorials and stackoverflow solutions and I dont get the results that I need.
I have a list of "patients" shown on a index page from a database.
Here is the code:
#if($data)
<table class="table">
<thead>
<tr>
<td>Nombre de Paciente</td>
<td>Cedula</td>
<td>Fecha</td>
<td>Telefono</td>
<td>Email</td>
<td>Direccion</td>
<td>Fecha de Creación</td>
<td></td>
</tr>
</thead>
<tbody>
#foreach($data as $row)
<tr>
<td>
{{ $row->paciente }}</td>
<!--<td>{{ $row->paciente }}</td>-->
<td>{{ $row->cedula }}</td>
<td>{{ $row->fecha_nacimiento }}</td>
<td>{{ $row->telefono }}</td>
<td>{{ $row->email }}</td>
<td>{{ $row->direccion }}</td>
<td>{{ $row->created_at }}</td>
<td>
</td>
</tr>
</tbody>
#endforeach
</table>
#endif
What I want to do, and as you can see, the "patient" name is a link, which referese to (in this case)a form.
I want to get two things from this.
ONE: I want to get the id of the patient I'm clicking on and the name of the "patient" and send it to the form page.
TWO: on the form page I want to show the "patient" name on the top of the form, and have the "patient_id" hidden to save it on the form table (this patient_id will be a foreing key)
This are my current components:
ROUTE:
Route::get('/care/{id}', [
'as' => 'create',
'uses' => 'CareController#create' ]);
CONTROLLER
public function create($id)
{
//
return view ($this->path.'.care',['id'=>$id]);
}
VIEW:
<div class="form-group">
<label for="exampleInputEmail">Paciente </label>
<input type="hidden" name="id" value="{{$id}}">
</div>
But whenever I load the page, it shows a blank page and on the url I see the following:
http://hospital.dev/care/$row->id
I really appreciate your help with this.
UPDATE:
THANKS.
Its sending now the id. But when trying to display the form page, it still sends the blank page, and the url is the following:
"http://hospital.dev/care/1"
I dont know if it is something on the controller:
CONTROLLER:
public function create($id)
{
//
return view ($this->path.'.care',['id'=>$id ]);
}
how should I pass the id value no to the url but to the view?

Answer 1

You could simply concatenate the href:
<a href='/care/{{$row-id}}'></a>
Once you have passed the id into your route. You can then handle with the route definition and pass it to your other controller.
for example a view that creates dynamic links:
#extends('layouts.app')
#section('content')
<div class="container">
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
<div class="panel-heading">Endpoint</div>
</div>
<table class="table table-bordered" id="endpoint-table">
<thead>
<tr>
<th>id</th>
<th>name</th>
<th>ip</th>
<th>mac</th>
<th>proxy</th>
<th>model</th>
</tr>
</thead>
<tbody id="endpoint-table-body">
#foreach($endpoints as $endpoint)
<tr><td>{{$endpoint->id}}</td><td>{{$endpoint->name}}</td><td>{{$endpoint->ip}}</td><td>{{$endpoint->mac}}</td><td>{{$endpoint->proxy}}</td><td>{{$endpoint->model}}</td></tr>
#endforeach
</tbody>
</table>
</div>
</div>
</div>
#endsection
then in your routes/web.php:
Route::get('/endpoint/{id}', 'EndpointController#show');
then it gets passed to the controller # function show where you can do some logic:
/**
* Display the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
$endpoint = Endpoint::getObjectById($id);
$e = new \stdClass();
$e->id = $endpoint->id;
$e->name = $endpoint->name;
$e->ip = $endpoint->ipaddress;
$e->mac = $endpoint->macaddress;
$e->model = $endpoint->model_id;
$e->proxy = $endpoint->proxy_id;
$endpoint = $e;
$endpoints = array();
$endpoints[] = $endpoint;
return view('endpoints', ['endpoints' => $endpoints]);
}
and when you return your view. You can pass it data passed from the function you defined on your controller. In this instance that function is show() on the EndpointController.

Answer 2

The reason that the url is http://hospital.dev/care/$row->id is because you are using single quotes, so it won't get the value of the variable.
In the list replace:
{{url('/care/$row->id')}}
With:
{{url('/care/'+$row->id)}}

Answer 3

Here you're echoing variable $row->id as a string <a href="{{url('/care/$row->id')}}">, you need to print the value.
Since you've got you routes named I suggest you rewrite it like this using route() helper:
<a href="{{ route('create', ['id' => $row->id]) }}">
Here I called the route() helper, passed the route name create as first argument and the {id} that the route expects as second argument.
Another way would be to just correct your method, by moving the variable out of '' and appending it to the url like this:
<a href="{{url('/care/' . $row->id)}}">
Period . appends a string to another string in php, not +

Answer 4

The link you are using is like id')}}">
so here you are printing the id as a string. But you need to use this like
id)}}">
OR
id}}">
