Write contents of Textarea in a form to an HTML file on a server.

[strawbshaker]

Hi There,

I am busy working on a project building my own javascript/php html editor. The javascript part is fine and dandy. I have worked out how to upload files from my hard drive to the server but what I really want to achieve is saving the contents of a form textarea into an html file to overwrite the contents of the file.

I do have the use of a MySQL database. I do want to try do it without the db though.

Can anyone tell me were to start? (ie. point me in the direction of a good tutorial or ebook or something)

Many Thanks!

you probably are gonna have to adjust the code, because this one is ment to be used for a guestbook, but it has the same cause!

<?php
$PreCheckComplete=0;
if ($_POST['submit']) {
   $Error='';

   $Name = $_POST['name'];
   if (!$Name) $Error .= "&bull; Name is a required field.<br>";
   if (strip_tags($Name) != $Name) $Error .= "&bull; You are not allowed to use html in your name.<br>";
   if (strlen($Name) < 3) $Error .= "&bull; Your name must atleast contain 3 characters.<br>";

   $Email = $_POST['email'];
   // TODO: perform an regex on email when provided.
   if ($Email) {
      if (strip_tags($Email) != $Email) $Error .= "&bull; You are not allowed to use html in your e-mail.<br>";
   }
   
   $Website = $_POST['website'];

   if ($Website) {

   }
