GET help

[Vivid Lust]

When the get "deleten" doesnt exist, the code still executes as if it did.

 

Basically, here's my code:

 

<?php
$get = $_GET['deleten'];
if($get !== ""){
echo "File deleted at: <a href=http://".$_SERVER["HTTP_HOST"].$get.">".$_SERVER["HTTP_HOST"].$get."</a>"; 
}
else
{
echo "<br>"; 
}
?>

 

All the time the "echo "File deleted at: <a href=http://".$_SERVER["HTTP_HOST"].$get.">".$_SERVER["HTTP_HOST"].$get."</a>";" displays, i think my coding is bad, please help xd

 

thanks in advanced!

<?php
$get = $_GET['deleten'];
if($get != ""){
echo "File deleted at: <a href=http://".$_SERVER["HTTP_HOST"].$get.">".$_SERVER["HTTP_HOST"].$get."</a>"; 
}
else
{
echo "<br>"; 
}
?>

 

Try that.

try...

 

if isset($_GET['deleten'])
{
    $get = $_GET['deleten'];
    echo "File deleted at: <a href=http://".$_SERVER["HTTP_HOST"].$get.">".$_SERVER["HTTP_HOST"].$get."</a>"; 
}
else
{
    echo "<br>"; 
}

$get = $_GET['deleten']; // if not set in the url a null value will be set for $get;

 

if ($get !== "") // null !== ""(string) thus execute what is on the next line

Go with Johnnys way. Also, your link is wrong. You're (or were) missing a quote to the left of the URL.

 

if isset($_GET['deleten'])
{
    $get = $_GET['deleten'];
    echo "File deleted at: <a href=\"http://".$_SERVER["HTTP_HOST"].$get."\">".$_SERVER["HTTP_HOST"].$get."</a>"; 
}
else
{
    echo "<br>"; 
}

yeah and johnny is missing a (

 

if (isset($_GET['deleten'])

{

    $get = $_GET['deleten'];

    echo "File deleted at: <a href=\"http://".$_SERVER["HTTP_HOST"].$get."\">".$_SERVER["HTTP_HOST"].$get."</a>";

}

else

{

    echo "<br>";

}
