Help returning boolean

[nathansizemore]

Hello,

I am trying to implement error proofing to a log in script.  But, I cannot get it to work?  I have no idea what is going on, or why it doesn't work like I expect it to.  I have tried everything, please advise.

 

This is the method I am calling:

public function i_exist($this_username)
{
	//$host_array = null;
	//$host_array = $this->collection->findOne(array("Username" => $this_username));
	//if ($host_array['Username'] = $this_username)
	//{
		return true;
	//}

	//return false;
}

 

This is where I am calling it:

if (!empty($_POST['Username']))
{			
	$host  = new Host();		
	$event = new Event();

	if ($host->i_exist($_POST['Username']))
	{
		header("Location: http://www.drink-social.com/error.php?login=duplicate");	
	}

 

 

It is supposed to check the database and see if that username is already in use.  But it never directs to the error page?  I have even tried commenting everything out and returning true, and returning 1.  Nothing?

Any advice?

Is $this->collection->findOne(array("Username" => $this_username)) supposed to be returning a username, or an object?

Returns an object.

Ok, well in your if statement you're doing an assignment, not a comparison.

 

if($a = $b) is not the same as if($a == $b)

Doh!

Aside from that slip-up, any idea why it isn't working in the current state of simply, return true;?

Found it.  I didn't have the code below wrapped in an else statement, so it directed to that page, but then continued to execute to another page.
