Sending JSON data from IONIC to Twilio PHP API - php

Question

Trying to send JSON data from my IONIC app to the Twilio PHP API located on my server.
IONIC APP:
I want to send an SMS to whatever mobile number is entered in the form's input (mobile) when the submit button(sendSMS) is clicked:
sendSMS() {
this.submitAttempt = true;
if(this.formGroup.valid){
var link = 'https://mywebsite.com/send-sms.php';
var myData = JSON.stringify({mobile: this.formGroup.controls[ 'mobile' ].value});
this.http.post(link, myData)
.subscribe(data => {
this.data.response = data["_body"];
});
}
PHP handling twilio request:
I don't know what I've missed or done wrong in the code below...I want to send an SMS to the JSON data (mobile input value) received from the IONIC app:
require __DIR__ . '/vendor/autoload.php';
use Twilio\Rest\Client;
$postdata = file_get_contents("php://input");
$account_sid = "mysid";
$auth_token = "mytoken";
$twilio_phone_number = "mymobile";
$request = json_decode($postdata);
$mobile = $request->mobile;
$client = new Client($account_sid, $auth_token);
$client->messages->create(
$mobile,
array(
"from" => $twilio_phone_number,
"body" => "hello"
)
);

Turned out it was a HTTP issue. For anyone else who is trying to use Ionic with a Twilio PHP script on their server:
require_once 'vendor/twilio/sdk/Twilio/autoload.php';
use Twilio\Rest\Client;
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');
}
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
header("Access-Control-Allow-Headers:
{$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
exit(0);
}$postdata = file_get_contents("php://input");if (isset($postdata)) {
$request = json_decode($postdata);
$userMobile = $request->mobile;
if ($userMobile != "") {
echo "Server returns: " . $userMobile;
$account_sid = 'your-twilio-account-sid';
$auth_token = 'your-twilio-authtoken';
$client = new Client($account_sid, $auth_token);
$client->messages->create(
$userMobile,
array(
'From' => "YOUR TWILIO NUMBER",
'Body' => "MESSAGE YOU WANT TO SEND",
)
);
echo "Sent message!";
} else {
echo "Could not send SMS";
} }
