I have simple website (thanks to htaacess only two people have an access there)

HTML Code:

<html> 
<head> 
</head> 
<body> 
<textarea name="spis" cols="40" rows="40"></textarea> 
</body> 
</html>

And I want that when user types sth in this text-area it is remembered. After some days when he cames (or another user) it can read, change it and save again.

Is it possible? If yes, how?

Yes, it's possible.
What you need to do, is set up a javascript event listener that will send the content of the textarea to a db (or in a cookie, if there is only 1).

For that, you will need to identify the user though.
Either via a cookie (weak, can be altered or dropped easily) or via a login form.
Then, each time the focus is lost on the textarea, use a xmlHttpRequest (ajax) object to send to the db which text-area it is, it's content, and the id of the user.

Next time he comes back to that page, simply check the db for existing content and pre-fill the textarea.

wow quite complicated. Is it a simplier way using for example txt file?

if yes will it code be complicated ? (anything besides html?)

Tripy's way is pretty elegant, though not as complicated as you think, but if you just wanted to have a single textarea that is part of a form, and displays the same content to everyone, saving its value to a file, that would be pretty simple.

You want it to show the same thing to everyone, or different things to different users? A community notepad or a personal notepad?

**win_pytacz** · 11-21-2010, 04:36 PM

It would be the same to all users (it will be 2 users). It is only for communicate these two people who have access to this site

**tripy** · 11-21-2010, 05:02 PM

Then it's even simplier.
Just save the textarea content on each unfocus, and replace the database value with it.

But what will happen if the 2 are there together?
I have to say, that maybe you should envisage another solution.
Maybe something like http://ajaxim.com/

You can use php code. remember the input data into database.

If you have PHP the following code works. You don't need a database because it uses a .txt file. You need to press a button to save it.

PHP Code:


			
<?php

if ( isset ($_POST ['message']) )

{

    file_put_contents ('message.txt', $_POST ['message'] );

}

?>

<html>

<head>

<title>Save Message</title>

</head>

<body>

<form method="post">

<textarea name="message" cols="40" rows="20">

<?php

include 'message.txt';

?>

</textarea>

<br />

<input type="submit" value="Save">

</form>

</body>

</html>

I couldn't be bothered writing !DOCTYPEs or anything, just so you know.

A simple solution like Mime's is more like what I was thinking of. The AJAX idea Tripy posted is pretty cool, but I suspect this is a complexity you're not ready to deal with.
