Form and function

[Hannibal]

Hi,

I'm trying to create a little online form for using base64_encode. The code is straightforward:

$s = "text string";
$e = base64_encode($s);

My form looks like this:

<form action="<?php b64_encode()?>" enctype="multipart/form-data" name="base64" id="base64">
Encode<br>
<input type="text" name="$s" value="<?php echo $s ?>" id="$s" size="60" maxlength="300"><BR><BR>
Output<br>
<textarea cols="60" rows="12" name="$e" id="$e"><?php echo $e ?></textarea>
<input type="submit" name="action" id="action" value="Submit">
</form>

The good news is that the script has not totally bombed out on me, but I'm not able to generate any output either.

What can I change to make this work?

Thanks

Try this :

<?
if(!$action)
	$s = "text string"; 
$e = base64_encode($s); 
?>
<form action="<?php $PHP_SELF?>" method=post enctype="multipart/form-data" name="base64" id="base64"> 
Encode<br> 
<input type="text" name="s" value="<?php echo $s ?>" id="s" size="60" maxlength="300"><BR><BR> 
Output<br> 
<textarea cols="60" rows="12" name="e" id="e"><?php echo $e ?></textarea> 
<input type="submit" name="action" id="action" value="Submit"> 
</form>

Thanks.

I think I'm beginning to get the logic from this little exercise. I had tried PHP_SELF from reading the manual, but the "action" was the missing piece.
