Guestbook chokes on special characters

[Beto]

Hi again, well I'm finally getting the guestbook working locally, but I have a problem yet to solve: when some could enter a set of characters as emoticons like :-) , :-( , or the "@" symbol etc in the Comments section, the guestbook chokes itself at the time of submitting.

I have tried adding some lines in the PHP code...

Code: [Select]


$Comments= ereg_replace(":-)", "\:\-\)", $Comments);


or deleting these lines, but even so it doesn't work. Any ideas? (I'm not yet quite skilled on PHP, evidently)

what if you do this :

$comments   = ereg_replace("[^A-Za-z0-9 \:\(\)\.\,\@\-\/\'\?\!]", "", $comments);

i'm not sure, give it a try and let me know.

max.

here's is my script but i don't really know what the problem is:

<?php
      $Name = ereg_replace ("[^A-Za-z0-9 ]", "", $Name);
    $Email = ereg_replace ("[^A-Za-z0-9 \@\.\-\/\']", "", $Email);
      $Comments = ereg_replace ("[^A-Za-z0-9 \@\.\-\/\']", "", $Comments);

      $Website = eregi_replace ("http://", "", $Website);
      $Website = ereg_replace ("[^A-Za-z0-9 \@\.\-\/\'\~]", "", $Website);

      $Name = stripslashes ($Name);
      $Email = stripslashes ($Email);
      $Website = stripslashes ($Website);
      $Comments = stripslashes ($Comments);

      if ($Submit == "Yes") {
         $filename = "GuestBook.txt";
         $fp = fopen ( $filename,"r");
         $OldData = fread ($fp, 80000);
         fclose ( $fp );
         $Today = (date ("l dS of F Y ( h:i:s A )",time()));

         $Input = "Name: <b>$Name</b><br>Email: <b><u><a href=\"mailto:$Email\">$Email</a></b></u><br>
                 Website: <b><u><a href=\"http://$Website\" target=\"_blank\">$Website</a></b></u><br>Comments:
                 <b>$Comments</b><br><i><font size=\"-1\">Date: $Today</font><br><br>.:::.";

         $New = "$Input$OldData";
   
         $fp = fopen ( $filename,"w");
         fwrite ($fp, $New, 80000);
         fclose ( $fp );
      }
      $filename = "GuestBook.txt";
      $fp = fopen ( $filename,"r");
      $Data = fread ($fp, 80000);
      fclose ( $fp );

      $DataArray = split (".:::.", $Data);

      $NumEntries = count ($DataArray) - 1;

   print "&TotalEntries = $NumEntries &NumLow = $NumLow &NumHigh = $NumHigh &Guest Book=";
      for ($n = $NumLow; $n < $NumHigh; $n++) {
      print "$DataArray[$n]";
         if (!$DataArray[$n]) {
         Print "<br><br><b>No More entries</b>";
         exit;
         }}
         
?>
