Question

Why is there one of my select options that put nothing in the query string at form submission?

Answer 1

A:

Hmm, did you try -1?

Answer 2

A:

A value of zero will get interpreted as "nothing" and therefore disappear from your $_GET. But that should be no problem in your case. You could also just test of the "results" is in the array to check if someone wants to see all. Or you change the zero to the string "all" and test for that.

if (!isset($_GET['results']) {
    //logic for building your query without a LIMIT
}

A:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <title>Your HTML5!</title>
    <?php
        if(isset($_GET['submit'])){
            echo $_GET['results'];
        }
    ?>
</head>
<body>
<form action="thisfile.php" method="GET">
<select name="results"> 
    <option value="0">Vis alle</option> 
    <option value="10">10 resultater per side</option> 
    <option value="20">20 resultater per side</option> 
    <option value="30">30 resultater per side</option> 
    <option value="40">40 resultater per side</option> 
    <option value="50">50 resultater per side</option> 
    <option value="75">75 resultater per side</option> 
    <option value="100">100 resultater per side</option> 
</select>
<input type="submit" value="submit" name="submit"/>
</form>


</body>
</html>

Are you trying like this? If yes then it seems to work on my local.
