Hi everyone!

I'm currently trying to implement a feature for some of my members to edit their own html pages using php. It's pretty simple code,

Code:

$handle = fopen($filename, "r"); 
$contents = fread($handle, filesize($filename));
echo "<form method=\"post\" action=\"admin.php?action=edit\"> 
	<strong>$filename</strong><br> 
	<input type=\"hidden\" name=\"file\" value=\"$filename\"> 
	<textarea name=\"content\" cols=\"100\" rows=\"40\">".$contents."</textarea><br> 
	<input type=\"submit\" name=\"update\" value=\"Update\"> 
	</form>"; 
fclose($handle);

And then updating it:

Code:

$filename = $_POST['file'];	
	if(is_writable($filename)) { 
	$handle = fopen($filename, "w+");
	$content = stripslashes($_POST['content']);
	fwrite($handle, $content); 
	fclose($handle);

it works just fine except that after I save it, all my encoded characters become decoded.   becomes a space, © becomes ©, etc. How should I prevent that??? Thanks!

fwrite($handle, htmlentities($content));

No, no I don't want all of my entities destroyed! Tags are still pretty useful in html.

I want to keep both my tags, and those elements that I've encoded with &. For example:

Code:

<html>
<head></head>
<body>
<p>These are some spaces &nbsp; &nbsp; &nbsp; &nbsp; </p>
</body>
</html>

When I copy that back into the file, I don't want php to make it

Code:

<html>
<head></head>
<body>
<p>These are some spaces      </p>
</body>
</html>

How do I do that??? thanks.

OK I see, you would want to use the htmlentities() function when you output within your textarea because the browser will pass the interpeted data.

Thank you so much!
