Variable Seems to be Losing its Data

[Frankie T]

Hey there,

 

Pretty frustrated with this. It seems so simple, but I've been staring at it and toying with it for ages, so I figured I'd post here. I have a variable called "$isTaken" that seems to be losing its value in an essential step in my function. Take a look.

function subdomainTaken($inputtedSubdomain)
{
//Initialize $isTaken to 'true'
$isTaken = true;
	echo "isTaken STARTS AS: <i>" . $isTaken . "</i><br />"; //FOR TESTING PURPOSES ONLY. VARIABLE HAS VALUE HERE

//Check subdomain in database
$subdomainDBQuery = mysql_query("SELECT * FROM `companies` WHERE company_subdomain = '$inputtedSubdomain'");
$foundResult = mysql_num_rows($subdomainDBQuery);

if ($foundResult > 0) {
	$isTaken = true;	
} else {
	$isTaken = false;
}
return $isTaken;	
}

 

By the time I get to the if statement, $isTaken has no value. I've echoed it to be sure. Any ideas?

 

Thanks,

Frank

Try var_dump()ing it instead of echoing it.

Ah! Thank you so much! I didn't know about that function. What you told me allowed me to rule out what I thought it was. Turns out, there was just an error in my logic.

 

Thanks again!

I thought that would help you figure out what was going on there . . .
