Why is my if statement not working?

Hi, I created a function that would only try to include a file if 'type' was in the url:

// Determines which blurb should be included
function blurbs() {
	if(isset($_GET['type'])) {
		$blurb = $_GET['type'];
		$blurb = "include " . $blurb . ".php;";
		return $blurb;
	}
	else {
		return false;
	}
}

Open in new window

but its still trying to include it!! It should not get past the if statement!?!

anyone know whats going on?

Those message means thast $_GET['type'] is empty: how pass you that value? With a form? Can you show us the form code?

@Rik-Legger I am still getting the same message

@marqusG I am not using a form. I am just trying to include something according to the link that was clicked

I changed it to this:

// Determines which blurb should be included
function blurbs() {
	if(strlen($_GET['type']) > 0) {
		$blurb = $_GET['type'];
		$blurb = $blurb . ".php";
		include $blurb;
	}
	else {
		return false;
	}
}

Open in new window

but still not luck

Then there is a value in $_GET['type'],
if you do like this you can see what it is:

// Determines which blurb should be included
function blurbs() {
        var_dump($_GET['type']); // Debugging
	if(strlen($_GET['type']) > 0) {
		$blurb = $_GET['type'];
		$blurb = "include " . $blurb . ".php;";
		return $blurb;
	}
	else {
		return false;
	}
}

it returns NULL

I will change my code so that it can't be null and see that works

		$blurb = $_GET['type'];
		$blurb = $blurb . ".php";
		include $blurb;
	}
