OK, looks like this handles refresh (resubmit) and back button issues.
Hitting back when on page 3 empties 'email', so resubmitting does a
brand new login. (If I'm missing something, holler.)
However, the seminal article at
http://www.theserverside.com/tt/articles/article.tss?l=RedirectAfterPost
says:
- Never show pages in response to POST
- Navigate from POST to GET using REDIRECT
- Always load pages using GET
I get the first and the second, and understand how to implement them.
The third, though. Sorry, I'm missing something. I simply don't
understand what they mean or how to do it. Can someone translate my
little a3.php page into 'using GET' instead of just grabbing the
session var again? And why is that necessary?
a standard HTTP request is a GET request.
using firefox and one of a number of extensions (firebug springs to mind)
you can actually view the request headers that are sent.
(P.S. I'll get to the issue of rearchitecting this via require instead
of using header() redirects,cough, cough, Richard Lynch, cough, cough
:) in a future message. One step at a time...)
yes - abusing redirects as described is wasteful. and certainly it's the
first time I've ever heard the statement 'Never show pages in response to POST'
sounds like hubris too me.

Re: [PHP] Writing text into images, and setting text size
Casey, Thank you for replying. Try imagettftext(). I did, as explained: $font = '/usr/share/fonts/truetype/freefonts/FreeSans.ttf'; $imagettftext($image, 20, 0, $x, $y-10, $textColour, $font, $text); So my questions remain: 1. 'FreeSans.ttf' is in my /usr/share/fonts/truetype/freefonts directory. But specifying it doesn't seem to work. How do I get the system to find the font? 2. I need the scripts I'm writing to be portable, so can I be sure of what fonts will be available, and will I be able to locate them? 3. I'm not really concerned about what font it is, just that it's large and readable. If there are other options than what I've explored here, then I would be open to those too.

i have a daemon running on that port that sends a message when it's got a
client connected
but the script above doesn't output anything it just loads my cpu up to 100
percent and thats it then it basically stops working. While i need it to
display the messages sent by server(daemon) to the user running the script
has anyone got any idea why it rejects to work? (yeah the daemon is written
in c++ if that matters)

Try imagettftext(). I did, as explained: $font = '/usr/share/fonts/truetype/freefonts/FreeSans.ttf'; $imagettftext($image, 20, 0, $x, $y-10, $textColour, $font, $text); So my questions remain: 1. 'FreeSans.ttf' is in my /usr/share/fonts/truetype/freefonts directory. But specifying it doesn't seem to work. How do I get the system to find the font? I wouldn't. First, I don't know of any standard fonts for linux, though there might be (As you have Arial or Times New Roman for windows). Second, It might be a safe_mode / open_base_dir issue, or a problem in GD or the freetype libraries if the path is right and the font exist. I would try something like dirname(__FILE__).'/fonts/Arial.ttf'... of course that would mean you need to create a fonts directory and copy Arial.ttf from your system to that location (violating the copywrite? ;) )... anyway, you can check that with any other font. 2. I need the scripts I'm writing to be portable, so can I be sure of what fonts will be available, and will I be able to locate them? Deploy the fonts along with your scripts... that's the only way I know. 3. I'm not really concerned about what font it is, just that it's large and readable. If there are other options than what I've explored here, then I would be open to those too. You can get some free fonts, and deploy them along with every project. I do so for a custom CAPTCHA script I've made.

[PHP] 'Define vs const' or 'file vs class'
Hi everybody This post is not so much a question to solve a problem but more in the direction: what would you do and why. I'm starting a new project and is preparing the basic layout for the application. In all my previous projects I have had a config file that all other files would require where I used 'define' to specify database connection parameters, site root, picture root and stuff like that. This works without problems, but as I have started to code more in a OO way, I was wondering if it would not me bore clean to create a site class with constants for all these values so instead of doing: echo 'a href=”' . ROOT . '”Go home/a'; I would do this: echo 'a href=”' . Site::ROOT . '”Go home/a'; The second might be more verbose in this case, but for a lot of values, being able to associate them with the site could prove quite valuable if you or someone else has to look at the code half a year from when it was original written. The verbose issue aside, having a config file separate from the actual code seems intuitively more clean (in my mind at least) and using a class for storing config values might no be the best of ideas. But the site class could be build from the config file either each time a script was requested or as part of the build process when your application is deployed to the server. Either way... both solutions would work what I'm looking for here is maybe some comments to the ideas before I go ahead with one of them.

in this case there is really no difference, especially if Site contains all
the values
that were originally in the file with define directives, the structure is
essentially
the same.
The verbose issue aside, having a config file separate from the actual

Either way... both solutions would work what I'm looking for here is

if you are going to have just one class contain all of the configuration
values
there wont be much difference from using define directives. one thing
about
define is its notoriously slow, so you would have that advantage.
generally, a benefit of using classes w/ constants is the namespace aspect.
so you could have Car::DEFAULT_COLOR and Plane::DEFAULT_COLOR
for example, but again, how much different is that from
define('DEFAULT_CAR_COLOR', 'red');
define('DEFAULT_PLANE_COLOR', 'blue');
i dunno. to be honest i typically use a mixture of both approaches. class
constants
for classes when they are appropriate and define directives for global
configuration
values.
strictly speaking i dont think having a class of all constants qualifies an
app
as 'more oo'; id say in java for example you simply dont have any other
choice.

Re: [PHP] Securing your Sites
2 things I've done to them to try to catch all... 1. GZiped them all (you'll have to download them to a machine and look at the source yourself, taking your own precautions and YES, they will scan malicious in this setup as they are all trojans/backdoors) 2. changed their extension to .txt on the server I'll also modify the server folder they are running on to disable php entirely later tonight so they can never execute it on it. When I reloaded them in my windoze box, my AV picked up on them in the cache as the trojans they are and disabled access to them in my browser's cache. Since I don't run php on the windoze box, there really was nothing to worry about and I could view the source in the browser. But if you didn't run AV on the system you looked at them at, installed them to your own local area and started playing with them, then you pretty much borked yourself. They are live code (hence why they were phps and should have just been source to view) and the only way to really pick them apart to view them. Considering that the code was phps and the server treated them as such never did my server execute them.

Re: [PHP] Securing your Sites
ALL of them should report trojan if you download them to your cache but only should be an issue if you have PHP installed on that machine and then execute that code in your own php server. They are all trojans/back door. But if you view the source then you aren't going to bork yourself. As they are now all tar.gz the AV scanners should all catch them as trojans, so you will need to tell your scanner to all you to access that folder, save it to your local drive and view the source in your favorite text editor to look at them.

small. But it seems that it can't be scaled in any way.
Have you tried 0, 1, 2, 3 and 4?
They are all built-in and different sizes.
So I thought I would try to specify a font and try something like
this:
$font = '/usr/share/fonts/truetype/freefonts/FreeSans.ttf';
$imagettftext($image, 20, 0, $x, $y-10, $textColour, $font, $text);
But I'm clearly not doing things quite right, and I have some
questions:
1. 'FreeSans.ttf' is in my /usr/share/fonts/truetype/freefonts
directory. But specifying it doesn't seem to work. How do I get the
system to find the font?
This should work, according to the docs...
Can the FreeSans.ttf file be read by the PHP user?
2. I need the scripts I'm writing to be portable, so can I be sure of
what fonts will be available, and will I be able to locate them?
You are plain out of luck here.
There is NOTHING you can rely on for fonts installed at all, much less
where they will be.
You'd have to package them in with your own software to be safe.
And that may open up licensing/legal issues...
3. I'm not really concerned about what font it is, just that it's
large
and readable. If there are other options than what I've explored here,
then I would be open to those too.
You could draw the image with a smaller font, and scale the whole
image up...
But that would usually not work well, as the scaling up has to
interpolate pixels, which rarely looks good...
You could also try using:
$font =
imageloadfont('/usr/share/fonts/truetype/freefonts/FreeSans.ttf');
if (!$font){
error_log(Unable to load font!);
$font = 5; //fall back to built-in font #5
}

[PHP] PHP Session Vars Flash Movie
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I have a small application made in flash, that uses a set of PHP scripts to pull data from a database. I've added sessions to this scripts so they would only return the data if a proper session has been initialized, the flash movie is hosted in a sessioned php as well so you can only see it if a session has been initialized. All of it works well, the flash movie calls the scripts and the scripts return the data if and only if a session has been started. all of this was tested on Apache 2.2.2 and PHP 5.1.6 and works as expected. however, moving the whole thing to another server running Apache 2.2.6 with PHP 5.2.4 does not work, the flash movie calls the scripts, but it seems to be calling them outside the session set in PHP, thus the scripts return and invalid session message, if we call the scripts directly once the session has been initialized they return the correct data. So, the question is, is the above working because we are relaying on some bug in the previous versions of apache+php or are we missing some setting in the new versions ? We have tried to find a relevant setting making a difference but so far we are not able to do so. Thank you very much for your help.

Re: [PHP] Writing text into images, and setting text size
Andrés,
Thank you for responding.
Deploy the fonts along with your scripts... that's the only way I know.
... I do so for a custom CAPTCHA script I've made.
This sounds like a good solution. I'm having a little trouble
implementing it, however.
I have what I believe is a freely distributable font called
FreeSans.ttf, and I put it in a directory called fonts in the base
directory of my site.
However, this seems not to work:
$font = 'fonts/FreeSans.ttf';
imagettftext($image, 20, 0, $x, $y, $textColour, $font, $text);
Putting a slash in front to specify starting from the base directory -
'/fonts/FreeSans.ttf' - does not seem to work either.
Looking in the manual, it seemed that maybe I needed to set the font
path with putenv:
$path = realpath('fonts');
putenv('GDFONTPATH=' . $path);
But this yielded no results.
Am I still getting the syntax wrong somehow?
Thank you for any advice.

I don't know what language this is. I'm curious -- what is it? It
might not work; it's untested except for syntax errors.

Hello,

For Example:

RE: [PHP] Writing text into images, and setting text size
I'm tempted to say that the problem is that the system is not finding the
font... you'd need to include the full path to the font (and it must be
readable for the user PHP runs on behalf).
Try the following:
Just for testing put the font and the script that generates the image in the
SAME directory, so let's say you have something like this:
arial.ttf (-- I just copied it from my windows fonts folder)
PrintImage.php
BOTH IN THE SAME DIRECTORY...
Then, the code for PrintImage.php would look like the following...
?php
//
/* Begin PrintImage.php */
// dirname(__FILE__) means the full path to the directory where this file
PrintImage.php is sitting
$fontFile = dirname(__FILE__).'/arial.ttf';
$imW = 200;
$imH = 100;
$im = imagecreatetruecolor($imgW, $imgH);
$bgColor = imagecolorallocate($im, 238, 239, 239);
$borderColor = imagecolorallocate($im, 208, 208, 208);
$textColor = imagecolorallocate($im, 46, 60, 31);
$whiteColor = imagecolorallocate($im, 255, 255, 255);
$fontSize = 18;
$textAngle = 0;
$codeString = 'Works!';
// Print rectangle
imagefilledrectangle($im, 0, 0, $imgW, $imgH, $bgColor);
imagerectangle($im, 0, 0, $imW-1, $imH-1, $borderColor);
// Print Text (Calculate Position)
$box = imagettfbbox($fontSize, $fontAngle, $fontFile, $codeString);
$x = (int)($imgW - $box[4]) / 2;
$y = (int)($imgH - $box[5]) / 2;
imagettftext($im, $fontSize, $fontAngle, $x, $y, $textColor, $fontFile,
$codeString);
// Output... no caching
header(Content-type: image/png);
header(Cache-Control: no-cache, must-revalidate);
header(Expires: Mon, 26 Jul 1997 05:00:00 GMT);
imagepng($im);
/* End PrintImage.php */
/**/
?
Then you know what you do... you load PrintImage.php into your browser and
you'll get a nice gray rectangle with the word Works! in the center of it. If
you don't get that... then you have a problem that is not related to path or to
PHP per-se... maybe it's a GD issue, or the font is broken... or whatever other
issue... but this code works in windows and linux provided that you get the
arial.ttf in the same directory as PrintImage.php.
And... use dirname(__FILE__) or similar (meaning ABSOLUTE PATHS), as much as
possible to reference other files for inclusion or processing... doing
./myfile.php or ../myfile.php leads to headaches... and usually in the
moment you can't take a headache (which is project deadlines).
Hope this helps,
Rob

Andrés,
Thank you for responding.
Deploy the fonts along with your scripts... that's the only way I
know.
... I do so for a custom CAPTCHA script I've made.
This sounds like a good solution. I'm having a little trouble
implementing it, however.
I have what I believe is a freely distributable font called
FreeSans.ttf, and I put it in a directory called fonts in the base
directory of my site.
However, this seems not to work:
$font = 'fonts/FreeSans.ttf';
imagettftext($image, 20, 0, $x, $y, $textColour, $font, $text);
Putting a slash in front to specify starting from the base directory -
'/fonts/FreeSans.ttf' - does not seem to work either.
Looking in the manual, it seemed that maybe I needed to set the font
path with putenv:
$path = realpath('fonts');
putenv('GDFONTPATH=' . $path);
But this yielded no results.
Am I still getting the syntax wrong somehow?
Thank you for any advice.

RE: [PHP] Writing text into images, and setting text size
Just a correction...
Replace at the beginning of the script (I had some typos, while extracting the
code from the original script)
$imW = 200;
$imH = 100;
By this..
$imgW = 200;
$imgH = 100;

Rob

Well, that's close to my point -- order and disorder, random and predictable are concepts in our minds that do not exist in nature. Once a series of events, or an arrangement of objects satisfies our mind's definition of order or random, then we define it that way.
