IF statement - not running correctly, prob something simple

[Canman2005]

Hi all

 

Something strange is happening.

 

I have an if statement, it looks like

 

if($_GET['folder'] != 4)
{
$sql = "UPDATE `messages` SET `read` = 1 WHERE `id` = ".$_GET['id']."";
$query = mysql_query($sql);
exit();
}

 

So it should run that query if the url looks like

 

page.php?folder=1

 

and if the url looks like

 

page.php?folder=4

 

then it shouldnt run, as the ?folder= value in the url is 4

 

But for some reason, this rule isnt happening and if the url contains ?folder=4

 

Does anyone know why this isnt working correcly?

 

Any help would be great

 

Thanks

 

Dave

Try

 

echo "GET_folder = " . $_GET['folder'] . "<br>";

 

either just before the if, or inside the if.
