Hi guys!

 

I’m trying to create a site to decrypt a scrambled alphabet.

It has been a while since I coded anything in PHP, so I thought this would be a good excise.

But I’m having trouble getting it to work the way I wanted it. Any help, thoughts?

 

<HTML>
<BODY bgcolor="#E0E0E0">

<h1>Scrambled alphabet</h1>

<?php
if(isset($_POST['save'])){
$a=$_POST["a1"];
$b=$_POST["b1"];
$c=$_POST["c1"];
$d=$_POST["d1"];
$e=$_POST["e1"];
$f=$_POST["f1"];
$g=$_POST["g1"];
$h=$_POST["h1"];
$i=$_POST["i1"];
$j=$_POST["j1"];
$k=$_POST["k1"];
$l=$_POST["l1"];
$m=$_POST["m1"];
$n=$_POST["n1"];
$o=$_POST["o1"];
$p=$_POST["p1"];
$q=$_POST["q1"];
$r=$_POST["r1"];
$s=$_POST["s1"];
$t=$_POST["t1"];
$u=$_POST["u1"];
$v=$_POST["v1"];
$w=$_POST["w1"];
$z=$_POST["z1"];
$y=$_POST["y1"];
$x=$_POST["x1"];
}
?>

Am I correct in thinking that what you are trying to do is allow a user to define a secret code such that they can make - for example - A=M, N=E, D=H. where crypted "AND" would output "MEH", and decrypted "MEH" would output "AND"?

 

Yup that was the idea!

Wow - Nice! I need to look a bit deeper into your code to understand how it works, but it looks way smarter then what i slashed together. (and it seems to be working)

 

Thank you very very much!
