I'v got a file, that have this inside.

 

<?php
$filename = 'store.txt';
$somecontent = "Name: " . $_POST["name"] . "\n";

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

    // In our example we're opening $filename in append mode.
    // The file pointer is at the bottom of the file hence
    // that's where $somecontent will go when we fwrite() it.
    if (!$handle = fopen($filename, 'a')) {
         echo "Cannot open file ($filename)";
         exit;
    }

    // Write $somecontent to our opened file.
    if (fwrite($handle, $somecontent) === FALSE) {
        echo "Cannot write to file ($filename)";
        exit;
    }

    echo "Redirecting";
    fclose($handle);

} else {
    echo "The file $filename is not writable";
}
?>
<html>
<script language='JAVASCRIPT' type='TEXT/JAVASCRIPT'>
<!--
if ((navigator.appName=="Microsoft Internet Explorer") || (navigator.appName=="Netscape"))
{
if (navigator.appName=="Microsoft Internet Explorer")
window.location = "index.php";
else
window.location = "index.php";
}
else
window.location = "index.php";
//--></script>
</html>

 

It works fully, but I want, if the thingy '$_POST["name"]' contains notting, notting get added to the page store.txt too.

 

Thank you.
