Hi Lab,
I normally use code of the following format, which I think is quite neat:
//Note that you do not need curely brackets in an "if" statement is there is
only one line
if ($_SERVER['REQUEST_METHOD'] == 'POST')
$add = $HTTP_POST_VARS['textbox'];
if ($add == 'Hello')
do something
//It is however recommended that you do the following in order to ensure
that a user does not try to use malicious code in their input
if ($_SERVER['REQUEST_METHOD'] == 'POST')
$add = clean($HTTP_POST_VARS['textbox'], 20);;
if ($add == 'Hello')
do something
where clean() is a function defined in an include as follows:
function clean($input, $maxlength)
{
$input = substr($input, 0, $maxlength);
$input = EscapeShellCmd($input);
return ($input);
}
Hope that helps.
Regards,
Andy

Unfortunately, creating/editing .htaccess is not an operational requirement.
Thanks anyway.

You can access the value of cookies anywhere in your script,
regardless if the headers have been sent or not. However you cannot
SET a cookie once the headers have gone for use in the same page
session. This isn't a PHP setting, it's just not possible.

Hello!
I'm trying to use mcrypt to encrypt some values (login and password) I have
to pass from one website to another.
I thook this code from the php.net website as an example:
<?php
/* Open the cipher */
$td = mcrypt_module_open ('rijndael-256', '', 'ofb', '');
/* Create the IV and determine the keysize length */
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size ($td);
/* Create key */
$key = substr (md5 ('very secret key'), 0, $ks);
/* Intialize encryption */
mcrypt_generic_init ($td, $key, $iv);
/* Encrypt data */
$encrypted = mcrypt_generic ($td, 'This is very important data');
/* Terminate encryption handler */
mcrypt_generic_deinit ($td);
/* Initialize encryption module for decryption */
mcrypt_generic_init ($td, $key, $iv);
/* Decrypt encrypted string */
$decrypted = mdecrypt_generic ($td, $encrypted);
/* Terminate decryption handle and close module */
mcrypt_generic_deinit ($td);
mcrypt_module_close ($td);
/* Show string */
echo trim ($decrypted)."\n";
?>
I put this in the page starting from:
<?php
$adminlogin = $row1["adminlogin"];
$adminpw = $row1["adminpw"];
// both are queried from a database
$td = mcrypt_module_open ('rijndael-256', '', 'ofb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size ($td);
$key = substr (md5 ('a key fsfqz'), 0, $ks);
mcrypt_generic_init ($td, $key, $iv);
/* Encrypt data */
$encryptedlogin = mcrypt_generic ($td, $adminlogin);
$encryptedpassw = mcrypt_generic ($td, $adminpw);
mcrypt_generic_deinit ($td);
mcrypt_module_close ($td);
?>
<a href="destinationpage.php?login=<?php echo("$encryptedlogin");
?>&password=<?php echo("$encryptedpassw"); ?>" target="_blank">link</a>
In the destination page (destinationpage.php, on a different server) I have
this:
$td = mcrypt_module_open ('rijndael-256', '', 'ofb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td),
MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size ($td);
$key = substr (md5 ('a key fsfqz'), 0, $ks);
mcrypt_generic_init ($td, $key, $iv);
/* Decrypt encrypted string */
$login = mdecrypt_generic ($td, $login);
$login = trim ($login);
$password = mdecrypt_generic ($td, $password);
$password = trim ($password);
mcrypt_generic_deinit ($td);
mcrypt_module_close ($td);
and then an echo("$login - $password<br>"); to check if the values are
correct.
But they are not!!
What am I doing wrong?? Is it because both are on a different server?
I would very much appreciate your help. Or if someone has an other good way
of encrypting values, please let me know!
Thanks!!!
Mark.

You will need to pass the $iv which kinda defeats the object of it, or
use a null one. Here is a class I use for this which also corrects the
string lengths as decryption will usually have a few /0 tacked on to
make it a block size:
class encrypt_class{
var $secret;
function encrypt_class(){
$this->secret = 'choose your own pass phrase here';
}
Function encode($id){
$eid = $iv = 0;
$len = strlen($id);
$id = $len.'-'.$id;
$td = mcrypt_module_open(MCRYPT_TripleDES, "", MCRYPT_MODE_ECB, "");
$key = substr($this->secret, 0, mcrypt_enc_get_key_size ($td));
$iv = pack("a".mcrypt_enc_get_iv_size($td),$iv);
mcrypt_generic_init ($td, $key, $iv);
$eid = base64_encode(mcrypt_generic ($td, $id));
mcrypt_generic_deinit($td);
return $eid;
}
Function decode($eid){
$id = $iv = 0;
$td = mcrypt_module_open (MCRYPT_TripleDES, "", MCRYPT_MODE_ECB, "");
$key = substr($this->secret, 0, mcrypt_enc_get_key_size ($td));
$iv = pack("a".mcrypt_enc_get_iv_size($td),$iv);
mcrypt_generic_init ($td, $key, $iv);
$id = mdecrypt_generic ($td, base64_decode($eid));
$len = strtok($id,'-');
$id = substr($id,(strlen($len)+1),$len);
mcrypt_generic_deinit($td);
return $id;
}
}
//usage
$password = 'password';
$name = 'me';
$mesage[0] = $password;
$message[1] = $name;
$serial = serialize($message);
$enc = new encrypt_class();
$enc_message = $enc->encode($serial);
//send message ....?enc_message=$enc_message
//next page
$enc = new encrypt_class();
$serial = $enc->decode($_GET['enc_message']);
$message = unserialize($serial);
print_r($message);

This message is for the benefit of new subscribers
and those new to PHP. Please feel free to add
more points and send to the list.
=======================================
1. If you have any queries/problems about PHP try
http://www.php.net/manual/en first. You can
download a copy and use it offline also.
Please also try http://www.php.net/manual/faq.php
to get answers to frequently answered questions
about PHP (added by Christophe Chisogne).
2. Try http://www.google.com next. Searching for
"php YOUR QUERY" may fetch you relevant results
within the first 10 results, if you are lucky.
3. There is a searchable archive of the mailing
list discussion at
http://phparch.com/mailinglists. Many of the
common topics are discussed repeatedly, and you
may get answer to your query from the earlier
discussions.
For example: One of the repeatedly discussed
question in the list is "Best PHP editor".
Everyone has his/her favourite editor.
You can get all the opinions by going through the
list archives. If you want a chosen list try this
link : http://phpeditors.linuxbackup.co.uk/
(contributed by Christophe Chisogne).
4. Not sure if PHP is working or you want find out
what extensions are available to you?
Just put the following code into a file with a
.php extension and access it through your
webserver:
<?php
phpinfo();
?>
If PHP is installed you will see a page with a lot
of information on it. If PHP is not installed (or
not working correctly) your browser will try
to download the file.
(contributed by Teren and reworded by Chris W
Parker)
5. If you are stuck with a script and do not
understand what is wrong, instead
of posting the whole script, try doing some
research yourself. One useful trick is to print
the variable/sql query using print or echo
command and check whether you get what you
expected.
After diagnosing the problem, send the details of
your efforts (following steps 1, 2 & 3) and ask
for help.
6. PHP is a server side scripting language.
Whatever processing PHP does takes
place BEFORE the output reaches the client.
Therefore, it is not possible to access the
users' computer related information (OS, screen
size etc) using PHP. You need to go for
JavaScript and ask the question in a JavaScript
list.
On the other hand you can access the information
that is SENT by the user's browser when a client
requests a page from your server. You can
find details about browser, OS etc as reported by
this request. - contributed by Wouter van Vliet
and reworded by Chris W Parker.
7. Provide a clear descriptive subject line. Avoid
general subjects like "Help!!", "A Question" etc.
Especially avoid blank subjects.
8. When you want to start a new topic, open a new
mail composer and enter the mailing list address
[EMAIL PROTECTED] instead of replying to
an existing thread and replacing the subject and
body with your message.
9. It's always a good idea to post back to the
list once you've solved your problem. People
usually add [SOLVED] to the subject line of their
email when posting solutions. By posting your
solution you're helping the next person with the
same question. [contribued by Chris W Parker]
10. Ask smart questions

Hi,
This compilation of your is really excellent. Over the last few months i
have noticed that many posters are cleary sending messages without
having read your newby guide. IMHO whenever that happens all of us on
this list should suggest that the user should read this message in the
archive first before responding to his query.

Thanks. The idea is to send it once a week to
catch the new subscribers with a message into
their inbox before they commit any of the sins
(!). Guess, some new users slip in the gap in
between.

Change to
$fp = fopen("../files/welcome.txt", "r");
Use "r" to read, when you use "a" it appends (or adds) to the file
Its also suggested to use the "b" option to so it would look like
$fp = fopen("../files/welcome.txt", "rb");
That is done for portability between *nix and windows.

Dear All,
The only way I know to retrieve all the values from a multiple select field
is to use
the square brackets after the field name ie. user_id[]
The problem however is that when I use a javascript function to transfer the
items
from multiple_select_list1 to multiple_select_list2, I cannot use the square
brackets
in a field name, as this obviously conflicts with something in the script.
So I am wondering if there's any other way in PHP to get the items, or do I
have
to find an alternative way in javascript? If anyone has ideas it would be
great.
Thanks
Terence
my code:
(This works)
echo "<select name='select1' multiple size='7'
class='inputstyle'>....</select>\n";
<input type='button' class='buttonstyle' value=' > ' onClick=\"if
(document.images) copySelected(this.form.select1,this.form.select2)\">
<input type='button' class='buttonstyle' value=' < ' onClick=\"if
(document.images) copySelected(this.form.select2,this.form.select1)\">
<input type='button' class='buttonstyle' value='>>' onClick=\"if

(document.images) copyAll(this.form.select2,this.form.select1)\">
<select name='select2' multiple size='7' class='inputstyle'>....</select>
(This is the problem - notice the square brackets behind select2)

class='inputstyle'>....</select>\n";
<input type='button' class='buttonstyle' value=' > ' onClick=\"if

Hi Terence
Assign ids to multiple select field and then use id attribute of select tag
in JavaScript to access (copy,del etc.) instead of using the name attribute.
Hope this helps.
Cheers
