// Open the file and write the tag to it
$write = fopen("content.txt", "w");

I need someone to insert a code so HTML is disable so people cannot type in HTML

id change your meta redirect to a header redirect, that way it causes no back button issues and is cleaner.

Easyest way to filter html is the lazymans way, aka use on of phps built in functions

htmlspecialchars()

so

$message = htmlspecialchars($message);

is the kinda of thing u want

Thanks will try.

Edit: OK Doesn't work, or can someone put entors script into my code, thanks.

PHP Code:

// This takes the smiley code in the message and turns it into a smiley

    '/:D/'
);

$image = array(

YESSSSSSSSSS!!!!!
YESSSSSSSSSSSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!

IT WORKS!!!!!!!!!!!!!! YEEEEEEEEEEEEEEEEEEEEEEEES!!!!!!!!!!!!!!!!!!!!!!!! !!

WOOOOOOOOOOOOOOOOHOOOOOOOOOO *KISSES FUJITSU* WOOOOOOOHOOOOOOOOOOOOOOOOOOOOOO

Lol I just tested it on your shoutbox and yep it works. Thanks to Mentor for the code and me for putting it in ;) :p

Yeah! Go say something now look what i made happen when a message is entered.. And when you leave a field blank..

Why, when I send a message with a blank or not blank fields, when I press submit it refreshes the alert like loads of times. I have to keep hold of enter and click google toolbar to get off it!

o.0 *Makes Longer* Dunno but ah well.

And it says. Thanks for your message Fujitsu, then alerts please enter name and message loads of times.

Hmmmmmmmmmmmmmmmmm

Now I think the site has crashed, it wont load.

I normally do something like this when inserting values using SQL:

PHP Code:

---

function PrepareSQLIn($val, $type, $defval = "", $notdefval = "") 
{
  $val = (!get_magic_quotes_gpc()) ? addslashes($val) : $val;

  switch ($type) {
    case "text":
      $val = ($val != "") ? "'" . $val . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $val = ($val != "") ? intval($val) : "NULL";
      break;
    case "double":
      $val = ($val != "") ? "'" . doubleval($val) . "'" : "NULL";
      break;
    case "date":
      $val = ($val != "") ? "'" . $val . "'" : "NULL";
      break;
    case "def":
      $val = ($val != "") ? $defval : $notdefval;
      break;
  }
  return $val;
}

//Make the SQL query

  $SQLQuery = sprintf("UPDATE something SET `value`=%s WHERE somethingelse=%s",
                       PrepareSQLIn($var1, "inserttypehere"),
                       PrepareSQLIn($var2, "inserttypehere"));
