PHP Postcard error help:

scorponok · August 17, 2010

hi,

I am developing a PHP Postcard system with Micro-Captcha Security and i get the following errors:

Internal Server Error, this is an error with your script, check your error log for more information.

or the code simply does not send the script I understand based on research that the problems lies with undefined variables:

I also used a PHP error code to display errors.

See code below:

<?php

session_start();
//check error log
ini_set('display_errors', 1);
ini_set('log_errors', 1);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
error_reporting(E_ALL);

// CHANGE PARAMETERS HERE BEGIN
$senderName  = " Holidays From Home "; // Eg.: John's Postcards
$senderEmail = "chris01@voluntary.awardspace.co.uk";  // Eg.: john@postcard.com
// Change only if you have problems with urls
$postcardURL = "http://".$_SERVER["HTTP_HOST"].$_SERVER["SCRIPT_NAME"]; //problem is here perhaps?
// CHANGE PARAMETERS HERE END
$result = 0;
$msg = "";
$msg1 = "";
$pic = "";
function displayPhotos()
{
global $pic;
$columns = 5;
$act = 0;
$act1 = 0;
// Open the actual directory
if($handle = opendir("thumbs"))
{
  // Read all file from the actual directory
  while($file = readdir($handle))
  {
   if(!is_dir($file))
   {
    if(isset($pic[1]))
    {
     if($pic[1] == $act1){$sel = "checked";}
     else{$sel = "unchecked";}
     }
    if($act == 0){echo "<tr>";}
    echo "<td align='center'><img src='thumbs/$file' alt='postcard'/><br/><input type='radio' name='selimg' value='$file,$act1' $sel/></td>";
    $act++;
    $act1++;
    if($act == $columns){$act = 0;echo "</tr>";}

       }
    }
  echo "</tr>";
  }    
}
?>
