[RESOLVED] make sure $_GET contains only one variable...else

[curb]

When I call ?name=phpbuilder, it would echo the first if statement. If I call ?name=phpbuilder&url=http://phpbuilder.com, it will still go to the first statement. How do I get it to read the 2nd statement? Making the 1st statement only accepting one variable in the url?

if ( isset($_GET['name']) ){
echo "there is only one variable which is name";
} 

elseif( isset($_GET['name']) && isset($_GET['url']) ){
echo "there are two variables with name and url";
}

One way is to just reorder the statements:

if (isset($_GET['name'], $_GET['url'])) {
    echo "there are two variables with name and url";
} elseif (isset($_GET['name'])) {
    echo "there is only one variable which is name";
}

laserlight's way is probably the best one. If you want to solve it using the order you have it now you could check that url is not set:

if ( isset($_GET['name']) && !(isset($_GET['url'])){
echo "there is only one variable which is name";
}

elseif( isset($_GET['name']) && isset($_GET['url']) ){
echo "there are two variables with name and url";
}

What exactly you are after is unclear to me.

What does this mean:
1. How do I get it to read the 2nd statement?
Usually by not make the 1st statement CONDITIONAL,
that is NOT using 'if'

2. Making the 1st statement only accepting one variable in the url?

And just because BOTH are set,
we can not even be sure ARE VALID LINKS

<?php

$name=isset($_GET['name']) ? $_GET['name'] : false;
$url   =isset($_GET['url']) ? $_GET['url'] : false;

if( $url && $name )
        echo 'I am confused. Dont know where to go ..';
elseif( $url )
        header('Location: '.$url );
elseif ( $name )
        header('Location: http://'.$name.'.com/' );
else
        echo 'Must Stay here! :(';

exit();
?>
