[SOLVED] Noob Help

[niallniall]

I want to make a simple code generator for my colleagues and I.

 

The idea is a give them a simple form in which they can enter a code into a box and press submit. They will be presented with the deciphered message.

 

All I want to do is replace letters with numbers or something else that is very simple.  I have hardly any php knowledge and any pointers would be really helpful.

 

Cheers

Ok Here is what I have so far I just need some help with the PHP bit to make this work. I only want to make the simplest codes possible.

[grlayouts]

firstly you must set out a rule.. ie 1=a 2=b, whats the code you have so far.

[niallniall]

OK got it working a bit.

Heres the code

 

results page

 

?php
$code = $_REQUEST['code'];

$code2 = $_REQUEST['code2'];
$code3 = $_REQUEST['code3'];
$code4 = $_REQUEST['code4'];
$code5 = $_REQUEST['code5'];
$code6 = $_REQUEST['code6'];

cipher is simple - a=b b=c and so on

 

I wanted to be able to type the code all into one box though and could not work out how to do it. Any help would be much appreciated.

 

Cheers

 

 

[niallniall]

Can someone please give me some advice on this? I'm sure I've gone a long way round to achieve what I have so far. I'd like the code all to go into the same field instead of a separate field one for each character.

 

Please help me someone

[AndyB]

Perhaps this would help:

 

<?php
if (isset($_POST['submit'])) {
$user_junk = strtolower($_POST['user_junk']);
$coded = "";
for ($i=0;$i<strlen($user_junk);$i++) {
	$char = $user_junk{$i};
	if ($char == "z") $char = "`"; // forced roll z to a
	$coded.= chr(ord($char) + 1);
}
echo $user_junk. " becomes ". $coded. "<br/><br/>";
}
?>
<form method="post">
Enter string to code <input type="text" name="user_junk"/>
<input type="submit" name="submit" value="go"/>
</form>

[niallniall]

Here it is :

 

Doesn't show the result.

 

How would I get the results to display in the same page?

 

Thanks for your help so far. I don't understand your php but I'm happy all the same

[AndyB]

Doesn't show the result.

As posted it works perfectly. Perhaps you've added it to your code improperly. Without seeing yours, who knows?

 

How would I get the results to display in the same page?

As posted, that's exactly what it does

 

Thanks for your help so far. I don't understand your php but I'm happy all the same

 

All explained in the manual

Here is some code that might help you thank AndyB for it i just edited a little to do the decrypting ..

<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
Enter string to code:<br>
<textarea name="user_junk" cols="20" rows="10">
</textarea>
<input type="submit" name="submit" value="encrypt"/>
</form>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
Enter string to decode:<br>
<textarea name="user_junk" cols="20" rows="10">
</textarea>
<input type="submit" name="submit" value="decrypt"/>
<p>
<?php
if ($_POST['submit'] == "encrypt") {
$user_junk = strtolower($_POST['user_junk']);
$coded = "";
for ($i=0;$i<strlen($user_junk);$i++) {
	$char = $user_junk{$i};
	if ($char == "z") $char = "`"; // forced roll z to a
	$coded.= chr(ord($char) + 1);
}
echo "Encryted Message:<br>".$coded. "<br/><br/>";
}
if ($_POST['submit'] == "decrypt") {
$user_junk = strtolower($_POST['user_junk']);
$coded = "";
for ($i=0;$i<strlen($user_junk);$i++) {
	$char = $user_junk{$i};
	if ($char == "a") $char = "z"; // forced roll z to a
	if ($char != "z")
	{
		$coded.= chr(ord($char) - 1);
	}
	else
	{
		$coded.= chr(ord($char));
	}
}
   echo "Decryted Message:<br>".stripslashes($coded). "<br/><br/>";
}
?>
</p>

EDIT:

CHANGED so that when z is used it can be decrypted.

also added character support

 

[niallniall]

Thank you so much guys. Atlanta you solved my problem thanks very much. Just one more thing; i need to add number 0-9 along side the letters. would you mind showing me how?

 

I feel cheeky asking but I've struggled with this all day and I really want to learn php.

 

Thanks again

[atlanta]

heres the new code.

Recoded it.

 

<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
Enter string to code:<br>
<textarea name="user_junk" cols="20" rows="10">
</textarea>
<input type="submit" name="submit" value="encrypt"/>
</form>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
Enter string to decode:<br>
<textarea name="user_junk" cols="20" rows="10">
</textarea>
<input type="submit" name="submit" value="decrypt"/>
<p>
<?php
if ($_POST['submit'] == "encrypt") {
$user_junk = strtolower($_POST['user_junk']);
$coded = "";
for ($i=0;$i<strlen($user_junk);$i++) {
	$char = $user_junk{$i};
	if ($char == "z") $char = "`"; // forced roll z to a
	if ($char == "9") $char = "/"; // forced roll 9 to 0
	$coded.= chr(ord($char) + 1);
}
echo "Encryted Message:<br>".$coded. "<br/><br/>";
}
if ($_POST['submit'] == "decrypt") {
$user_junk = strtolower($_POST['user_junk']);
$coded = "";
for ($i=0;$i<strlen($user_junk);$i++) {
	$char = $user_junk{$i};
	if ($char == "a") $char = "{";  // forced roll z to a
	if ($char == "0") $char = ":";  // forced roll 0 to 9
	$coded.= chr(ord($char) - 1);
}
   echo "Decryted Message:<br>".stripslashes($coded). "<br/><br/>";
}
?>
</p>

Thanks you once again it works just the way I wanted it too. You guys are brilliant.
