Fatal error: Call to a member function query() on a non-object

mwu

The error is:

Fatal error: Call to a member function query() on a non-object in /home/vbarmy/public_html/wu/class_login.php on line 51

line 51:

$result = $sql->query('SELECT username, password, activation FROM users WHERE username = "'.$username.'"');

The object is created here:

$sql = new sql(dbhost, dbuser, dbpass, dbname);

Thanks.

Either the object failed to instantiate, your code unset the object ($sql) in some manner, or the variable $sql is out of scope where it is currently being used. I'd put my money on the last one if I had to bet, but there's no way to tell with the current info.

If the line that is failing is within an object method, perhaps it just needs to be $this->sql->query(etc....), perhaps?

Anyway, if that doesn't get you pointed in the right direction, we'll probably need to see more of the code to understand the context within which this is happening.

Got it. Thanks!

Another thing just also be careful of, is that you're not stomping on your class variable by mistake:

$v = new Validator();
$v->checkOneOf($consent, array('A', 'D'), 'Condition precedent');
foreach ($sectionaccess as $k=>$v)
{
	if (!is_numeric($v))
	{
		/* won't work, the foreach stomped on $v */
		$v->addCustomError("Invalid access"); 
	}
}

This was resolved for the poster in the end, but this post is really high in google for the poster's error message!

That would have been less likely if descriptive variable names like $validator and $value were used instead of $v.
