dennisvdz Posted May 19, 2009 Share Posted May 19, 2009 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.
