load files in a textarea on click using php?

I am using the following code in order to load a file into a textarea on my page. this works as it should. however, I need to be able to make changes to the loaded file and save it.

the problem that i have is that I can load the file in the textarea but i cannot save it and i keep getting this error: Error opening file in write mode!

This is my current code:

PHP code:

$fn = $_GET['p'];

if (isset($_POST['content']))

{

    $content = stripslashes($_POST['content']);

    $fp = fopen($fn,"w") or die ("Error opening file in write mode!");

    fputs($fp,$content);

    fclose($fp) or die ("Error closing file!");

}

HTML CODE:

<a href="?p=PAGE.html">PAGE.html</a>


<textarea id="code"  style="width:450px;"  rows="25" cols="50" name="content"><?php readfile($fn); ?></textarea>

The code above will load the PAGE.html into the textarea if you click on the <a></a> link, but it wont allow me to make changes to the file.

but if i change $fn = $_GET['p']; to $fn = 'PAGE.html';, everything works fine and i can make changes to the loaded file and save it without any errors.

could someone please advise on this issue?

Thanks

Its because when you post the file, it's not appending the page name, so the $_GET variable will be empty when you submit it to save.

You have it as a $_GET variable when you click the link.

But when you post the form, you aren't posting with the $_GET variable anymore. So instead just include it in the form as a hidden field, and use $_REQUEST to get it regardless whether its a $_GET or $_POST

So like this...

$fn = $_REQUEST['page'];

and your html to this...

<a href="?page=PAGE.html">PAGE.html</a>


<input type="hidden" name="page" value="<?php echo $fn;?>" />
<textarea id="code"  style="width:450px;"  rows="25" cols="50" name="content"><?php readfile($fn); ?></textarea>
