[PHP] ImageColorAllocate() Problem
I am having a bizzare problem with the imagecolorallocate() function. Maybe
all of you can help me!
Here is the code:
$hex1 = 0x.$color{0}.$color{1};
$hex2 = 0x.$color{2}.$color{3};
$hex3 = 0x.$color{4}.$color{5};
$color = ImageColorAllocate($im, $hex1, $hex2, $hex3);
Simple enough! $color starts off as a hex color code minus the #, and then
is pulled into each of the 3 alpha values by way for the hex variables. It
is later outputted in text:
ImageTTFText ($im, $cursive_size, 0, $text1_x, $text1_y, $color, $font1,
$cursive_text);
Problem: The text is always black.
Something strange: If I just type in a randomly selected color, it works!
Is there some reason that the values in my variables wouldn't be passing?
Thanks in advance,
Jed R. Brubaker

RE: [PHP] ImageColorAllocate() Problem
I think it might be because you're passing a string to the function instead
of a hex value...
try changing it to this and see if it works
$color = ImageColorAllocate($im, hexdec($hex1), hexdec($hex2),
hexdec($hex3));

[PHP] Re: undefined function imagecreate()
You know, I am not sure if this will help, but I have a problem very similar to this in my debugger. When I run a script check through my WIN32 PHP module, I get errors related to imagecreate() functions. In a current project I use imagecreatefromjpeg() functions and get the same problems. Fortunately for me, once my scripts have gone up to the server they have worked fine. You might have the same luck! One other thing - you might want to check the image capabilities of your PHP's build. One server I worked on did not have the capabilities to work with GIFs or PNGs, so I had to do things with imagecreatefromjpeg() (as I mentioned above). Good luck!

Use hexdec() function
$hex1 = hexdec(substr($color,0,2});
$hex2 = hexdec(substr($color,2,2});
$hex3 = hexdec(substr($color,4,2});
and it just passes normal numbers to ImageColorAllocate($im, $hex1, $hex2, $hex3)

Uh... first, that's correct behaviour for %u Second, you're trying to find the absolute value of an integer: echo (abs(-86)); Third, how to explain the behaviour you're seeing. Um... Binary numbers are made up of two symbols, right? 0 and 1. There's no room in a binary computer for a third '-' symbol to denote negative numbers, so you have to overload one of your existing symbols to signify negative. Ok, lets work with 8-bit numbers to simplify things. An unsigned 8 bit number can run from 0 to 255: = 0 0001 = 1 [...] 1110 = 254 = 255 By convention, a signed 8-bit number sacrifices it's left-most column to denote negative (1) or positive (0), so it can run from -127 to +127: = -127 1110 = -126 [...] 1001 = -1 = 0 0001 = 1 [...] 0110 = 126 0111 = 127 Hope you're with me so far - signed numbers use the left-most column to store the sign of the number. If the left-most column is 1, the number is negative. What you are doing with %u is forcing printf() to treat a signed number with a leading 1 as if it was an unsigned number. Thus, an unsigned int 1001 = -1 would be interpreted as 1001 = 129 This stuff is very basic Computer Science. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

How can I make it in the sense that this cell colour can be changed permanently to the colour I want(even when I reopen this file using a new browser) until I changed the colour again. Futhermore, how can I store the colour code into the database(MySQL)??? Any special datatypes for that? Hope to get some help. Thanks.

[PHP] mysql query
ok im stumped lol i have used this code in the past to insert data into
mysql (im relitively new though)
--code
mysql_query(INSERT INTO Images (Image, desc) VALUES ('$name',
'$description')) or die (mysql_error());
--end code-
but i get this error]
-error-
You have an error in your SQL syntax. Check the manual that corresponds to
your MySQL server version for the right syntax to use near ''Image', 'desc')
VALUES ('2419091.jpg', 'stone')' at line 1
--- end error--
I found if i just try and record the name value it works fine but if i try
to add the description i get the error.
Any clues?

Re: [PHP] Creating Objects!
Webmaster wrote:
let us say there is Class A.
In the constructor of this class I create an Object B of Class B.
Now what is the difference between these two ?
this-B = new B;
and
B = new B;
The this object always points to the current instance of an object. So
whenever you refer to a variable with $this-, you are accessing the
variable that is in the current object's memory space. Here is an example :
class a {
var $foo;
var $bar;
function a()
{
$this-foo = Hello ;
$this-bar = World;
$foo = Widgets;
}
function dump()
{
echo $this-foo.$this-bar;
}
}
$obj = new a();
$obj-dump();
This above snippet will print Hello World, because the $foo variable
that is created in the constructor does not have object scope. In other
words, $foo only exists in that function. You can verify this by using
the print_r function thusly :
echo pre; print_r($obj); echo /pre;
To answer your original question, the difference between using $this-
and not is that with $this- the variable referenced is one that exists
in the object's scope. If you want to create an instance of the object
that you don't plan to use in other members of that class, then you can
make it local to that member by omitting $this-

[PHP] NEW: XML Application Objects
I've just released the first distribution for an open-source project called XML Application Objects (XAO). It's the result of working with XML/XSLT in PHP for a couple of years now. Although this is an alpha release, the concept itself has gone through a lot of refinement and is now ready for prime time. The publication of the project itself was partially motivated by the discussions that took place in this thread (A Complete List of PHP Template Engines?) which basically sees me arguing for the usage of standards (XSLT) rather than having to learn a proprietary new templating system every time you work on someone elses PHP app. This project is the result of much blood, sweat, and tears so I hope someone out there finds it useful. I have made documentation a paramount considderation for the XAO API because I'm keen for it to be another PHP success story. The website has a tonne of information so I'm not gonna try and promote XAO in this message.

[PHP] Committing OO Sin
Or is there such a thing. ;) I have a small collection of utility classes, and it seems like the more I add, the more cumbersome things seem to get. A brief synopsis of code execution. 1. Start DB class 2. Start Smarty class, passing reference of DB class to Smarty 3. When needed start Date-Time class 4. When needed start Text-Format class, passing reference of Smarty class to Text-Format class, which also has a reference to the DB class. (Im using both within the Text-Format class) Currently, I have a file of functions that handle user management, a possible candidate for a class. If I were to convert it, it would go between steps 1 and 2, and would need a reference to the DB class. Then the Smarty class is going to need a reference of the proposed user management class. By that time, Smarty contains itself, a reference to the DB class, reference to the user management class which in turn contains a reference to the DB class. All these references, are beginning to worry me, to the point where Im second guessing myself, that Im going about this the wrong way. Making utility classes are somewhat straight forward, but getting them to work together, seems like a pain. So I was thinking, if a class was started in the global space, is it a sin, to use the $GLOBALS array to access it, instead of tying in all these references??

I think reasons like your above are why people, quite often these days, create frameworks. Frameworks are generally designed from the ground up to provide the kind of interactions you are moving towards while at the same time, loosely coupling the interactive pieces to provide flexibility. With regards to the question of sin -- most books regard them as dirty dirty little beasts. That said, the entire PHP philosophy revolves around globals. In my opinion though, the internal globals used by PHP are fine, but blatant creation by your own code is generally a design flaw. There are times when it is useful to create a global, for instance I encapsulate all of my framework's data via a single globals variable ($GLOBALS['interJinn']). A purist might argue that this is bad; however, the purist could not do any better since to create an object to hold such data would still require an anchor point somewhere in the global space. From this I think it follows that too many global variables -- poor design. The occasional global variable -- good design (notwithstanding other design issues :) Cheers, Rob. -- .. | InterJinn Application Framework - http://www.interjinn.com | :: | An application and templating framework for PHP.

Re: [PHP] NEW: XML Application Objects
Hi Terence, I am equally puzzled as to why people are using all sorts of crappy proprietory template systems instead of XSLT. It's particularly useful when dealing with WAP. I suspect the reason could well be the inconsistencies in compiling php with XSLT support. compiling the Sablatron module for perl on the other hand is a breeze and over the last year or so whenever i did anything with xslt it's always been with perl. Can i contribute to your project? Terence wrote: I've just released the first distribution for an open-source project called XML Application Objects (XAO). It's the result of working with XML/XSLT in PHP for a couple of years now. Although this is an alpha release, the concept itself has gone through a lot of refinement and is now ready for prime time. The publication of the project itself was partially motivated by the discussions that took place in this thread (A Complete List of PHP Template Engines?) which basically sees me arguing for the usage of standards (XSLT) rather than having to learn a proprietary new templating system every time you work on someone elses PHP app. This project is the result of much blood, sweat, and tears so I hope someone out there finds it useful. I have made documentation a paramount considderation for the XAO API because I'm keen for it to be another PHP success story.

[PHP] set the PHP to look at library files.
Hi, I am running PHP with apache. I put all my webpages in the htdocs folder. A lot of my scripts use a bunch of open source libraries. Until now I have been including these libraries in my scripts by defining a full path to the library 'inc' files. If I put the library itself in my htdocs folder I can see it. However, I want to simply include the library by saying: include (xmlrpc.inc); I don't want to put the absolute path in the include statement nor do I want to have the xmlrpc.inc file in the same directory as the script that needs it. Is there a some configuration setting in the php.ini file that I can set so that It always points to some path to look for the include files (It would be nice if the any thing below that path is also seen if I set the path. So if i set the path in the configuration to see /usr/home/ , even if i put something under /usr/home/install/.. I will be able to pick it up.) Thank in advance for any help.

On each protected page, put an IF ($logged == yes) { //show page etc }
else {//show login form etc }
All good, works fine hooray for me...
BUT...
I'm aware that a slight increase in a users browsers security setting, and
this doesn't work...
So... I've started to learn. sessions.
I have a few questions, that my texts books seem to pussy foot around, and
I get no answer...
1. Can sessions work in the same way as my cookies? (Just remember a value
to a variable, accross many page)
2. can seesions be set up to work accross browser sessions? (If I close my
browser, will they work when I open a new one?)
3. I've seen on many web sites a 'remember me' checkbox. I'd love to learn
how to do that, is that session related? what's the step in teh right
direction to remembering that?
Any advise, or first rate turtorials are welcome...

--- [EMAIL PROTECTED] wrote: 1. Can sessions work in the same way as my cookies? (Just remember a value to a variable, accross many page) Yes, they address the same challenge: persisting data. Also, please realize that sessions can use cookies for identification. One of the benefits of using sessions is that the session data is stored on the server. This has some security benefits. 2. can seesions be set up to work accross browser sessions? (If I close my browser, will they work when I open a new one?) Yes, however, this won't necessarily be automatic for you. As long as the client identifies itself (via persistent cookie or URL variable) on the next visit, and the session itself has not expired, you will resume the session. 3. I've seen on many web sites a 'remember me' checkbox. I'd love to learn how to do that, is that session related? Yes, but it is usually more related to cookies. Many of these sites only set a persistent cookie if you check this box, otherwise requiring you to login again if you close your browser. What exactly is in this cookie depends on the site; some sites may only store your username (so you still have to type in your password again), while others store your session identifier (and hopefully some information to deter impersonation), so that your session is automatically resumed when you revisit. For a general overview of cookies, you can read this free chapter: http://shiflett.org/books/http-developers-handbook/chapters/11 Hope that helps.

[PHP] PHP and .HTACCESS
I am new to learning PHP and have learned a lot over the last few weeks. One
thing that I can not find anywhere is how to code it so a user can click logoff
and have it route them to another page and remove their authentication that was
set.
ie... I user goes to www.mysite.com and clicks on a link called STAFF
The STAFF.mysite.com is protected with authentication using .htaccess
The staff enters their ID and Password and is allowed in.
I want to have a button that says LOGOFFF that will remove the authentication
I know how to do the header(location... to route them back to another page, but
I have not been able to remove the authentication so it will ask them for their
password again when they return to staff.mysite.com
I have even tried:
header('WWW-Authenticate: Negotiate');
header('WWW-Authenticate: NTLM', FALSE);
but no go...
Thanks in advance!!

I want to have a button that says LOGOFFF that will remove the authentication HTTP authentication is not a very good tool for implementing sophisticated access control. Though it is possible to simulate a log out, it is not very straightforward (some would call it a hack), because there is no mechanism for the server to instruct the browser to forget the authentication credentials. So, I recommend using PHP sessions instead. However, if you really want/need to use HTTP authentication, you can read this page to get some other users' suggestions: http://www.php.net/features.http-auth Hope that helps.

Re: [PHP] PHP and .HTACCESS
it is virtualy impossible to make the browser forget the credentials.
How this is solved is that the logoff link is
login.php?logoff=username
In login.php you check for $_GET['logoff'] variable, if it is set you
will not let the user with the same name ($_GET['logoff']) log in.

I don't know of any good books for patterns. much of what I know I
learned in university and from experience. But to take your problem and
perhaps give you a window on how you can organize things I will try to
lay out a possible plan.
Known classes:
- User manager (um)
- db connection (dbc)
- smarty (smarty)
- comments (comments)
Relationships:
- um uses smarty, dbc
- smarty uses dbc
- comments uses um
Proposal:
- middle man (mm) it's almost imperative to have a middle man
class that can return necessary instances of object (whether
it be multiple instances or a singleton). In InterJinn this
middle man class is the dynamic loader.
- database manager (dbm) to return database connections. This
could be a pooling mechanism for a given connection so that
you only ever return one connection. This has a problem
though if you wish to do a query based on the results of
another query without storing all the data from the first
query. There really isn't much difference in processing time
when using a pool and when returning a new connection.
InterJinn uses a pool for the default MySQL database layer,
but not for the Pear DB database layer. Pear DB may use
its own pool, but that's not for the user of the class to
care about (black box coding).
- dbc is a single connection, whether it be pooled or not. The
only guarantee you should have is that it won't interfere with
another query (if pooled then the dbm should only return the
same connection if it has been freed.
- um should be a factory, you give it a userId, or name
and it returns a user object which the appropriate methods to
retrieve/store user information.
- user object (user). Singleton for a given user (don't want to
update multiple copies of a single user object). The um can pool
user objects according to user Id and return references when
requested.
- I'm not sure why smarty has a reference to a database
connection in your code (though I'm not greatly familiar with
Smarty since I've only used it in conjunction with other
people's code that was already using it). At any rate, unless
you are extending the smarty class, then you should give it
it's own database connection to use. if you wanted you could
always create a smarty manager layer to retrieve smarty objects,
but this probably isn't necessary for your own work.
- the connection object isn't used by anything, so it should just
be a regular object.
For simplicity I'm going to assume I made all my management objects part
of the middle man class with a very simple interface:
lets say I have code that needs to display user stats, comments, and via
a smarty template. I might have the following:
?php
include_once( 'middleMan.inc' );
include_once( 'Smarty.class.inc' );
mm = new MiddleMan();
$userId = $_SESSION['userId'];
// Reference since proposal called for a singleton user system.
$user = $mm-getUser( $userId );
$comment = new Comment();
//
// Not sure what the purpose of comments are, so I'll just skip
// details.
//
$template = new Smarty();
$template-assign( 'USER_NAME',$user-getName() );
$template-assign( 'USER_ADDRESS', $user-getAddress() );
$template-assign( 'COMMENTS', $comment-getText( $userId ) );

RE: [PHP] User authentication

Anything look wrong or insecure with all of this?
The only thing that catches my attention is your assignments
for $_SESSION['userid'] and $_SESSION['userpassword']. I
assume you are performing some strict data validation on
$userid and $userpassword before this assignment, right? If
not, this presents a significant risk, because $_SESSION is a
trusted array (it comes from the server, not the client).
Hope that helps.

Well both variables $userid and $userpassword are bounced off of a user
database table, if the username/password don't match then the session
variables are cleared with a session_destroy() call. Is that a good
enough validation?
[code begin]
session_start();
if(!isset($userid)) {
login_form();
exit;
}
else {
$_SESSION['userid'] = $userid;
$_SESSION['userpassword'] = $userpassword;
$username = auth_user($userid, $userpassword);
if(!$username) {
echo user . $userid . $userpassword . Authorization
failed. .
You must enter a valid userid and password
combo. .
Click on the following link to try
again.BR\n;
echo A HREF=\$PHP_SELF\login/ABR;
echo If you do not have login, please contact
Operations to obtain one.br\n;

}
else echo welcome, $username!;
echo gmmktime();
echo a href='./test_auth.php'Continue/a;
echo a href='./new_ticket.php'Ticket/a;
}
function auth_user($userid, $userpassword) {
global $default_dbname, $user_tablename;
$link_id = db_connect($default_dbname);
$query = SELECT username FROM $user_tablename WHERE userid =
'$userid' userpassword = password('$userpassword');
$result = mysql_query($query);
if(!mysql_num_rows($result)) return 0;
else {
$stamp = gmmktime();
$query2 = update $user_tablename set idle_time = $stamp
where userid = '$userid';
$result2 = mysql_query($query2);
$query3 = select CanEdit from $user_tablename where
userid = '$userid';

$query_data3 = mysql_fetch_row($result3);

Hi there, I would like to send an arbitrary file to a user. This file will be on the server in the PHP directory. I will also want to rename it before it is sent, but keep the old file with the old filename. Any help is appreciated...

Is that a good enough validation? Yes, as long as you realize that you have now shifted the trust to those values in the database. As long as there is no way for a user to inject malicious code during the registration process (or however the username and password end up in the database), then that part should be fine.
