Simple write to file script

[CloudConX]

<?php

$filename = 'logfile.txt';

 

if (is_writable($filename)) {

 

  if (!$handle = fopen($filename, 'a')) {

        echo "Cannot open file ($filename)";

        exit;

  }

 

  if (fwrite($handle, $input) === FALSE) {

      echo "Cannot write to file ($filename)";

      exit;

  }

 

  echo "Success, wrote ($input) to file ($filename)";

 

  fclose($handle);

 

} else {

  echo "The file $filename is not writable";

}

?>

 

in the url I have http://www.site.com/logger.php?input='blahblah'

 

I get an output of "Success, wrote () to file (logfile.txt)";"

no matter what the variable I use (eg. logger.php?blah=blah) returns the same thing

 

This will not write the input to the text file... permissions set. Any guesses?

Looks like you either need register globals to be "on" (not recommended) or to use the $_GET[] variables:

 

<?php
$filename = 'logfile.txt';

if (is_writable($filename)) {

   if (!$handle = fopen($filename, 'a')) {
         echo "Cannot open file ($filename)";
         exit;
   }

   if (fwrite($handle, $_GET['input']) === FALSE) {
       echo "Cannot write to file ($filename)";
       exit;
   }

   echo "Success, wrote ($_GET['input']) to file ($filename)";

   fclose($handle);

} else {
   echo "The file $filename is not writable";
}
?>
