Drupal 7 Not Recognizing Twilio Client in Custom Module - php

Question

I have a Twilio account and I am writing a mass text message module for my Drupal site. At the beginning of the module I have set up the Twilio client with the following code:
$path = drupal_get_path("library", "twilio");
require($path . "twilio/Services/Twilio.php");
$accountSID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$authToken = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$client = new Services_Twilio($accountSID, $authToken);
$from = "xxxxxxxxxx";
The myModule_submit() queries the database for phone numbers and sends them out via the Twilio PHP libraries referenced above. I am using code found on the Twilio site for something similar here(http://www.twilio.com/docs/howto/sms-notifications-and-alerts). The problem is when I fill in the forms for the SMS message to be sent out and press submit I get the following error message:
Notice: Undefined variable: client in myModule_submit() (line 128 of /var/www/erosas/anysite.com/sites/all/modules/myModule/myModule.module).
Notice: Trying to get property of non-object in myModule_submit() (line 128 of /var/www/erosas/anysite.com/sites/all/modules/myModule/myModule.module).
Notice: Trying to get property of non-object in myModule_submit() (line 128 of /var/www/erosas/anysite.com/sites/all/modules/myModule/myModule.module).
The submit function is:
function myModule_submit($form, &$form_state){
// Retrieve the values from the fields of the custom form
$values = $form_state['values'];
// Use Database API to retrieve current posts.
$query = db_select('field_data_field_phone_number', 'n');
$query->fields('n', array('field_phone_number_value'));
// Place queried data into an array
$phone_numbers = $query->execute();
$body = $values['sms_message'];
// Iterate over array and send SMS
foreach($phone_numbers as $number){
$client->account->sms_messages->create($from, $number, $body); // This is line 128
}
}
Any thoughts/help would be greatly appreciated, I tried searching this site and Google for an answer, but nothing specific to Drupal came up.

Answer 1

$client object is n/a to the submit function. Try putting the same code
$path = drupal_get_path("library", "twilio");
require($path . "twilio/Services/Twilio.php");
$accountSID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$authToken = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$client = new Services_Twilio($accountSID, $authToken);
$from = "xxxxxxxxxx";
in the beginning of the submit function.
function pulsesurf_submit($form, &$form_state){
$path = drupal_get_path("library", "twilio");
require($path . "twilio/Services/Twilio.php");
$accountSID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$authToken = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$client = new Services_Twilio($accountSID, $authToken);
$from = "xxxxxxxxxx";
// Retrieve the values from the fields of the custom form
$values = $form_state['values'];
// Use Database API to retrieve current posts.
$query = db_select('field_data_field_phone_number', 'n');
$query->fields('n', array('field_phone_number_value'));
// Place queried data into an array
$phone_numbers = $query->execute();
$body = $values['sms_message'];
// Iterate over array and send SMS
foreach($phone_numbers as $number){
$client->account->sms_messages->create($from, $number, $body); // This is line 128
}

Better making some include function without arguments the simply includes the library files and sets the tokens/sid for ease of use.
and btw, your site's domain is in the error message.
