Call to a member function getDOM() on a non-object - php

Question

I'm trying to create a PHP function that adds an event to a google Calendar. It appears to be building the object correctly but it throws a "Call to a member function getDOM() on a non-object in FeedEntryParent.php" error when trying to add the event. Here is the abbreviated class with only the constructor and the function that adds the event:
class GCal_datasource {
private $user = 'xxxxxxx';
private $pass = 'xxxxxxxxx';
private $client;
private $gdata_cal;
private $calendar;
private $visibility;
public function __construct($settings = NULL){
session_start();
require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Gdata');
Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
Zend_Loader::loadClass('Zend_Gdata_HttpClient');
Zend_Loader::loadClass('Zend_Gdata_Calendar');
if($settings == NULL){
$settings = array();
$settings['calendar'] = 'default';
$settings['visibility'] = 'full';
}
$this->calendar = $settings['calendar'];
$this->visibility = $settings['visibility'];
$this->client = $this->get_ClientLoginHttpClient();
$this->gdata_cal = new Zend_Gdata_Calendar($this->client);
}
public function create_event($fields){
$gc = $this->gdata_cal;
$new_event = $this->gdata_cal->newEventEntry();
echo '<pre>';
print_r($fields);
echo '</pre>';
if(isset($fields['quick_add'])){
$new_event->content = $gc->newContent($fields['quick_add']);
$new_event->quickAdd = $gc->newQuickAdd(true);
} else if (isset($fields['title']) && isset($fields['when'])) {
$new_event->title = $fields['title'];
$where = $gc->newWhere($fields['where']);
$new_event->where = array($where);
$desc = $gc->newContent($fields['desc']);
$new_event->content = $desc;
$new_event->content->type = 'text';
$new_event->when = self::build_when_array($fields['when']);
if(isset($fields['web_content'])){
$new_event->link = web_event_array($fields['web_content']);
}
}
echo '<pre>';
print_r($new_event);
echo '</pre>';
$gc->insertEvent($new_event);
return $created_event->id->text;
}
}
The error (I believe) is how I am calling insertEvent() towards the end of the code. The only reason I think that is I only get the error when it exists and if I remove it the echo above it prints out the Event object as intended.
Anyone with a better grasp of the Goggle PHP API that can lend me a hand I would greatly appreciate.

Answer 1

I had this problem.
I think you have to change string
$new_event->title = $fields['title'];
to
$new_event->title = $service->newTitle($fields['title']);

Call to a member function getDOM() on a non-object in FeedEntryParent.php means that somewhere in the file named "FeedEntryParent.php" you have called getDOM() on a variable and that variable is not an object and so does not have a getDOM() method.
Nowhere in the code you posted is a call to getDOM(), so the error is not generated in the posted code.
Track down that call to getDOM(). The error usually gives you a line number. See what variable you are calling the method on. That variable is not an object. Find where that variable is set - that's probably where your problem is.
