Delete Method in PHP 7 not recieving parameters - php

Question

we are programming a Restful API to be called from an ionic app. We are sending from angular service with this code:
.service('ServiceName', function($http) {
return {
borrarAlumno: function(par) {
var link = "http://localhost/ws/index.php";
return $http.delete(link, {
id: par.id
})
}
}
})
When we try to read id parameter from php we dont get anything. This is the code we are using:
if (isset($_SERVER['HTTP_ORIGIN'])) {
header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Max-Age: 86400'); // cache for 1 day
}
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
header("Access-Control-Allow-Methods: GET, POST, DELETE, PUT, OPTIONS");
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
header("Access-Control-Allow-Headers:{$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
exit(0);
}
$input = file_get_contents('php://input');
print_r($_SERVER['REQUEST_METHOD']);
exit();
We have tried with similar code to get parameters with PUT, GET and POST methods and it worked.
Any help would be appreciated.
Edit:
This php is called form another PHP:
class AlumnosAPI
{
public function API()
{
header('Content-Type: application/JSON');
$method = $_SERVER['REQUEST_METHOD'];
switch ($method)
{
case 'GET':
include('get.php');
break;
case 'POST':
include('post.php');
break;
case 'PUT':
include('put.php');
break;
case 'DELETE':
include('delete.php');
break;
default:
echo 'NOT SUPPORTED';
break;
}
}
}
Edit 2: full code of delete.php
if (isset($_SERVER['HTTP_ORIGIN']))
{
header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Max-Age: 86400'); // cache for 1 day
}
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS')
{
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
header("Access-Control-Allow-Methods: GET, POST, DELETE, PUT, OPTIONS");
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
header("Access-Control-Allow-Headers:{$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
exit(0);
}
$valor['borrado'] = 0;
include('conexion.php');
$id = "";
//parse_str(file_get_contents('php://input'), $delete);
$input = file_get_contents('php://input');
print_r($input);
exit();
foreach (array_keys($delete) as $key)
{
$$key = $delete[$key];
}
if ($id != "")
{
//PREPARAMOS LA SENTENCIA SQL
$sql = "DELETE FROM Alumnado WHERE `ID`=?";
$resultado1=$conexion->prepare($sql);
$resultado1->bind_param('i', $id);
$resultado1->execute();
$valor['borrado'] = $resultado1->affected_rows;
}
$datos=json_encode($valor);
echo $datos;

Angular doesn't send a request body for DELETE so you're going to have to read id from the URL.
.service('ServiceName', function($http) {
return {
borrarAlumno: function(par) {
var link = "http://localhost/ws/index.php";
return $http.delete(link, {
params : {id: par.id}
})
}
}
})
get the id via $_GET['id'] instead of file_get_contents('php://input');
