request simple crypt please

[Anon]

Does anyone have a simple efficient "pseudo" crypt/decrypt function?

Here's what I want: I want the visitor's name and address to carry over to my next page, but I don't want the visitor's name and address to blatantly appear in the URL window.

There's no real need for "genuine encryption," as there is nothing sensitive; I just want it for aesthetic reasons.

Here is an example. What I have now:
<a href="nextpage.php">click here</a>

What I don't want:
<a href="nextpage.php?visitor=<?php print $visitorinfo; ?>">click here</a>

(I don't want that because it will show this in the URL location of the browser: nextpage.php?John Doe 123 Apple Street Anytown)

What I do want to see in the URL window:
nextpage.php?oueljeljdfoudjdfdoeuoljeljlejjdljuouodjrj3473jduodldfj (you get the idea)

And, then, on the nextpage.php, it'll decrypt it.

thanks

Oh, by the way, I don't want to use hidden inputs because as far as I know, I cannot have a javascript rollover image button submit a form unless I write a whole page of complicated code :-)

You could use base64_encode and base64_decode. Or use sessions, which in my opinion is a "cleaner" solution.

Hi,

If you don't want the hassle of encoding/decoding, use forms!!! This is how you do it:

<form name="nextform" action="next.php" method=post>
<input type="hidden" name="address" value="1111 test lane">
</form>

<!-- here's your image-->

<a href="javascript:document.nextform.submit();"><img src="image.gif" border=0></a>

basically you are calling the submit() function on the hidden form. As far as I know, all browsers (ns3+, IE3+, aol 5+, opera 4/5/6, etc) support the submit() javascript function.
