Use of URL Fields in Doctrine

Question

I am building the site and planning on implementing OpenID. I can get an OpenID URL back from Google, but Doctrine appears to do funny things with URLs in the where clause of my query. How can I fix that?

Here is the function

/* This function queries docrtrine for a user OpenID URL
 * and returns the user object.
 */
function getUserByUserOpenIDURL ($userOpenIDURL) {
  $q = Doctrine_Query::create()
     ->select('*')
     ->from('jsgUserOpenID as u')
     ->where('openid_url = ' . $userOpenIDURL);

  return $q->fetchOne();
}

Here is the error from the page

Fatal error: Uncaught exception 'Doctrine_Exception' with message 'Couldn't find class www' in /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Table.php:299 Stack trace: #0 /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Table.php(256): Doctrine_Table->initDefinition() #1 /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Connection.php(1126): Doctrine_Table->__construct('www', Object(Doctrine_Connection_Mysql), true) #2 /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Query.php(1934): Doctrine_Connection->getTable('www') #3 /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Query.php(1732): Doctrine_Query->loadRoot('www', 'www') #4 /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Query.php(713): Doctrine_Query->load('www.google') #5 /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Query/Where.php(121): Doctrine_Query->parseClause('https://www.goo...') #6 /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Query/Where.php(81): Doctrine_Query_Where->_buildSql('openid_url', '=', 'https://www.goo.. in /Library/WebServer/Documents/ResearchPM/lib/Doctrine/Table.php on line 299

Youre not escaping variables appropiately. There is two methods, by named or positional wildcards:

$q = Doctrine_Query::create()
       ->select('*')
       ->from('jsgUserOpenID as u')
       ->where('openid_url = ?', $userOpenIDURL);

Or

$q = Doctrine_Query::create() 
       ->select('*') 
       ->from('jsgUserOpenID as u') 
       ->where('openid_url = :url', array("url" => $userOpenIDURL));

This properly escapes the variables you're inserting, and makes your app secure against sql-injection
