Andras,
<input type=hidden name=item[] value=apples>Apples <input type=text
name=qty[] value=0> <input type=text name=price[] value=0>
Will get you where you need to go on the HTML side of things, then on
the back end you need to process each array. By setting a default value
of 0 for the qty, you force users to change the values, but you also
keep your arrays intact and easier (IMHO) to deal with.

Wolf,
The tip worked great !! All working as expected now...
$listvals=$_POST['item'];
$n=count($listvals);
$i=0;
while ( $i < $n ) {
if ($qty[$i] > 0) {
AddItem($item[$i], $qty[$i]);
UpdatePrice($item[$i], $price[$i]);
}
$i++;
}

Andras,

a useful addition can be to use the item id in the 'key' of the input names
(and always quoting your element attributes is highly recommended):
<input type="hidden" name="item[18]" value="apples">Apples <input type="text"
name="qty[18]" value="0"> <input type="text" name="price[18]" value="0">
that way you can easily fish out the quantities when looping the
selected items (example mostly ignores input cleaning/validation for brevity
etc -
but you shouldn't :-) e.g. get anal about make sure things are actually
integers when
that is what you require, etc):
foreach ($_POST['item'] as $itemId => $itemName) {
if (isset($_POST['item'][$itemId]) && ($qty =
intval($_POST['item'][$itemId])) {
addItem($itemId, $qty);
}
}
another thing that popped into my head was the fact that it's
probably not intended behaviour to allow the customer to determine the
unit price of an item -
but if it is then can I have 10 Plasma Screens at 1 dollar a pop? ;-)

Yes, when I generate my cart I use the itemID as a key field (since the
ID stayed the same but the # in the database could change).
And ALWAYS quote your inputs in HTML. It makes for a lot less
headaches. But then I wasn't sending COMPLETE code, just enough to get
him on the right track. :)
We should all be using the guidelines within http://phpsec.org/ to keep
good coding practices.

I too need the screens at 1 dollar (52" Wide-screen format please) as
well as the 6-person hot-tub and deck combo.

It works if you are calling from the webserver that the chat program is
working so i feel it is some type of config problem or security issue.
http://www.hidho.com/chattest.htm is the page that uses the code
<a href="javascript:pophelp('

Do you have access to the source of statusimage.php?

Since this is open source code ('phpOnline') available at
http://www.dayanahost.com/phponline.cfm
I guess it's safe to post an excerpt here:
...
[a number of mysql statements without error checking or other exits]
...
[concluding with:]
header ("Content-type: image/jpeg");
if($LastAdmLoginTime==0 || $LastAdmLoginTime<($TTime-120))
{
echo implode('', file('pathtooffline.jpg'));
$OnlineStatus = 0;
}
else
{
echo implode('', file('pathtoonline.jpg'));
}
Since both of these images are present (i.e. can be accessed directly)
and since there isn't any exit prior to the execution of the above
statement, I conclude that the program must be erring out before it gets
here.
Check your php error log first. If you don't find anything there then
edit the program to add error checking for all the sql commands.
You might also find help at the phpOnline forums:
http://www.dayanahost.com/forum2/index.php?act=SF&f=11&;
If you can't find the problem, since the program is short, you could
post it to the list.

Hi,
the PHP newbie is here again asking questions.
Is there anyway in PHP to convert none international characters so the are
displayed correct?
In my case I have lots of data in the database with å,ä and ö.
Thanks // Jonas

If your db uses a character encode that doesn't support all the characters
in the character set of the string you want to store, this characters will
be lost when converting from one set to another, and there will be no way to
convert them back. The proper solution is to set the correct character set
in your db.

I am having an issue with certain pages preventing the user from going back
to the previous page.
The message given by Firefox is: "The page you are trying to view contains
PSTDATA that has expired from cache".
This happens in the case of an HTML form using the POST method but also a
query object in the URL.
In this case: index.php?id=shopping_cart in my URL, along with a bunch of
form data you carry from page to page in a shopping cart (quantities, what
to remove, addresses, payment info, etc...)
Is this due to the fact that I am mixing POST and query objects or is it
something else?
I already tried adding the following but it does not help:
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
Thanks for your help!

Hi!
The thing I want to do is to copy a picturefile to another picturefile.
The thing is that I want to copy this file, show it , and then delete it
(when it has been shown) .Is this possible?
I want to do this, because of avoiding problems with cache when uploading
file through an admin-online-system... (the customer uses IE)
When I delete the file in code down below, the picture is not shown (I guess
because the browser hasn't rendered out all info?)
If you want more code, tell me :-)
Best regards
/Gustav Wiberg
$fileName = "pictures/products/$dbIDProduct1" . "_small";
$ran = strval(mktime()); //Current time
if (file_exists($fileName . ".gif")) {
copy($fileName . ".gif", "pictures/products/1_$ran.gif");
showpicture("pictures/products/1_$ran.gif", $dbProductName1, 300, 150,
"top");
//deletefile("pictures/products/1_$ran.gif");

I had to do something similar to keep a javascript file from being
cached by an aol proxy. Heres a simple example that you could change
to suit your needs by changing the js to something like image.php and
making it send image headers and outputting the contents of your file.
1) Rewrite rule in httpd.conf or virtual.conf
=======================================================================
RewriteRule ^/lib/(.*)/test.js.php /lib/test.js.php [QSA,L]
2) Create test.js.php in /lib/test.js.php
=======================================================================
<?php
header('Content-Type: text/javascript');
?>
3) Access url: http://example.local/lib/4908574987/test.js.php. You
can create your url like /lib/time()/test.js.php.
This way you don't have to worry about creating and deleting files.

Hi,
In the past few weeks I've found the need for a hash table and a container
that gives me O(log) search efficiency. Now I'm aware I can use associative
arrays for my hash table, but I wanted to ensure efficiency. For my O(log)
container I ended up using a sorted array, and a binary search (which I had
to write).
Now I thought common data structures, and algorithms, like these, and many
others such as Binary Trees, Red/Black Trees and sorting algorithms and so
on would be a useful addition to PHP, or more specifically PEAR, however I
was unable to find any previous classes that provided these structures.
So I figured I would make a set of containers and algorithms that could be
used in a generic way , and hopefully put this code into PEAR. But before I
start making nice PEAR code, I wanted to ask why nothing like this already
exists? Is it because everyone has been to lazy until now, or is there a
real reason that I'm missing that has made such structures pointless.
thanks for any comments/replies

sounds like a good idea. probably the reason it doesn't exist is because
the entry level for making something worthwhile is high - and most people
with such needs end up building something specific because it's easier.
if you do go the PEAR route my suggestion would be to avoid all/any of the
PEAR base classes - to save bloat and make the components more usable for
people who don't want/need PEAR (or are not allowed to use it).

Andrew:
I know what you are talking about, I wrote a splay binary-tree demo, see:
http://www.sperling.com/freeware.php
I've often wondered if there are algorithms like that in php buried somewhere.
However, binary-trees are for searching and I use MySQL for that. I
don't know specifically how MySQL preforms searches. I had hoped that
somewhere one could set a bit and change the algorithms, but I
haven't been able to find any references that allow that.
In any event, the size of the things I work with (<50k items) are so
small that it really doesn't matter for me -- and I don't know at
what size where it starts to be a problem for others.
So, if I was to take my previous code and port it over to php, I
would most certainly test it against MySQL for performance before
spending too much time providing something that doesn't significantly
improve the status-quo.

They more than likely don't exist because PHP's associative array is
O(lg n) and so everything else is pretty much just as good, except not
quite as good because it will be implemented in PHP whereas the internal
associative array is in C. Additionally PHP already provides all you
could probably need for sorting. If this is purely for academic fun then
I'd say go ahead, but if you are thinking real life applications, then
I'd suggest spending your time on algorithms that don't have a
just-as-good alternative already implemented internally.
BTW, I don't think you can make an O(1) hash table in PHP since even if
you succeeded in making a perfect hash then PHP will perform O(lg n)
lookup into whatever structure you've made.
Cheers,
Rob.

My question is, what is "psacln"?
In all the reference material I've looked at, that column is absent.
Is that the "name" for the group?

No problem being a dick -- my question was "is psacln the group"?
The answer was "Yes". I was looking for conformation.
Thanks.

which is a question about the *nix filesystem - bit off the scope for
this list.
btw 'psacln' is a group created by Plesk Hosting Software installations.
googling for 'psacln' on its own actually would have given you this info
and confirmed that it is indeed a user group.
The answer was "Yes". I was looking for conformation.
confirmation as in confirm not conform.

Hi (please insert your preference):
This should be simple, but I'm having problems.
I have a program that uploads an image file and then tries to set the
permissions for the image (to be altered later). However, I get a
"Warning: chmod(): Operation not permitted" error when trying to set
the permission, what gives? If my program created the file, shouldn't
it have permission to set the files permissions?
What am I not understanding?
Without seeing code, permissions of the directories, what sticky bits
might or might not be set, etc., you could not be understanding many
things....or just one....who knows.
I read all of your Google links, but no help. Just another example of
how Google is not the answer.
Then you're asking the wrong question.
In any event, my code is pretty simple, just:
chmod($url, 0755); //where $url is the file I want to change.
The error I receive is noted above in the subject line.
The permissions of the directories vary, but the folder that has the
file I want to change permissions is currently set at 0777.
Nice security there. Regardless, even if the user your webserver is
running as has write permission to the directory (don't know who
owns/what group that directory belongs to, as you didn't tell us that),
you won't be able to change permissions of a file in that directory if
the file isn't owned by the same user apache is running as.
In doing a lstat() of both the parent program that created the file and
the child file shows that they both have the identical uid and gid
(i.e., the same user and group id's).
And what user does Apache run as?
Now, everything I've read, says:
chmod() changes the permission of the specified file with the following
caveat.
"chmod() can only change the permissions of files that are owned by the
user running the command. In most cases, this is the user that the web
server runs on."
That confuses me, because who's the user here? Is it just the system
administrator or the application?
And if it is just the system administrator, then can't the system admin
change anything he/she wants anyway? What's the point of having uid and
gid's if a program can't change the permissions of a sibling file?
This question should answer the previous question for you.
I have tons of references as to what php filesystem functions are
available, but I need a good reference as to what permissions are and
how they actually can be changed in php -- does anyone have one a good
reference OR care to explain?
As it is now, I know how ride the horse, but I can't get the gate open.
File permissions is beyond the scope of this mailing list. You need to
buy a book, research on the web, etc., on *nix system administration,
and concentrate on the filesystem/security/permissions sections, and the
section on how apps/daemons operate.

John:
My question basically was "why isn't chmod() working for me?" So, I
thought it might be a question to pose to a php mailing list -- my
mistake, sorry.
In any event, I'll figure it out.
Thanks.

PS: 0777 -- so you never go to extremes, or press limits, to try to
solve a problem?

chmod() is working the way it's supposed to. You're not getting the
results you desire, and to understand why, you need to understand how
file ownership and permissions work on a *nix system.
PS: 0777 -- so you never go to extremes, or press limits, to try to

Not when it will compromise the security of my system. There is always
another way to solve the problem.

This is the user that Apache (or whatever webserver) is running as. If
you're using Apache, look at your httpd.conf file to find out who that
user is. If you're creating files successfully, you can just look at
the owner of that file to find out who it is.
Is safe_mode enabled?
>From the manual (http://us3.php.net/chmod):
In my code, I use:
ini_set( 'safe_mode', '0' );
Which I think disables "safe_mode" and from what I've read, the
default is off and in my phpinfo, it says it's 'off" -- so I think
it's off. :-)
Note: When safe mode is enabled, PHP checks whether the files or
directories you are about to operate on have the same UID (owner) as the
script that is being executed. In addition, you cannot set the SUID,
SGID and sticky bits.
I understand that, except for the sticky bits -- I don't know what
they are, but will look them up later.
But safe_mode is off, so any application should be able to chmod(), right?
However, when my application tries to change permissions via chmod(),
it fails and generates a warning.
BUT -- considering that this is a permission issue and not a php one,
as I've been told, I'll end this thread and look elsewhere for an
answer.
Thanks.

Our organization is migrating away from Novell E-directory to MS Active
Directory. I have a php class that allows me to run various queries on our
e-directory ldap server which I am working to convert to AD. However, I'm
running into an error that i cannot figure out. I have updated the base_dn to
point tothe correct location (verified by a third party ldap browser). Also
added a username and password since our AD environment doesn't allow anonymous
queries. The error I get is
Warning: ldap_search() [function.ldap-search]: Search: Operations error in
/var/www/html/intranet/_php/class.ldap_test.php on line 149
On that line I have this line of code
$result = ldap_search($this->conn,$this->base_dn,$filter);
Where $this->conn evaluates to Resource id #3, $this->base_dn is the correct dn
(ou=something,dc=domain,dc=domain_part_2) and $filter is cn=myusername
Can anyone shed some light on this? Below is the entire method from the class.
function connectldap($filter,$override=false) {
//connect to the server
$this->conn = ldap_connect($this->server);
//if the connection failed, set the error message
//and return false
if(!$this->conn) {
$this->errMsg[] = "Unable to connect to server\n";
return false;
}
//ldap_set_option($this->conn, LDAP_OPT_PROTOCOL_VERSION, 3);
//bind the connection. This function will perform an
//anonymous query to get the full
$bind = @ldap_bind($this->conn,$this->ldap_user,$ldap_passwd);
if(!$bind) {
$this->errMsg[] = "Unable to bind to server\n";
return false;
}
echo "<p>$filter - " . $this->conn . " - " . $bind . " - " .
$this->base_dn . "</p>\n";
//run the ldap query
$result = ldap_search($this->conn,$this->base_dn,$filter);
//if the search failed, then return false and set the error
message
if(!$result) {
$this->errMsg[] = "Search failed - " .
ldap_error($this->conn) . "\n";
return false;
}
//get the entries and store them in a variable
$info=ldap_get_entries($this->conn,$result);
//if the number of entries reutnred is zero, then the user
//could not be found in the ldap server
if($info["count"] == 0) {
$this->errMsg[] = "User Unknown\n";
return false;
}
//otherwise, if the number of entries found is greater than 1,
then
//more than one object was found.
elseif($info["count"]>1 && !$override) {
$this->errMsg[] = "There was more than one user
found\n";
return false;
}
else {
return $info;
}
}
Thank you,
