[PHP] PRG pattern - how to implement a load page using GET
I've been reading up on login mechanisms using redirects, and have a
basic mechanism down.
a1.php:
?php
$site_title='My Site';
if (isset($_SESSION['errmsg_s']))
{$errmsg = 'Warning! '.$_SESSION['errmsg_s'].'!';}
else
{$errmsg = ''; }
if (isset($_SESSION['email_s']))
{ unset($_SESSION['email_s']);}
echo 'h1Welcome to '.$site_title.'/h1br';
echo $errmsg;
?
!-- form goes here and calls a2.php --
a2.php:
?php
$email = $_POST['email'];
if // (test email for goodness against database) {
$_SESSION['email_s'] = $email;
unset($_SESSION['errmsg_s']);
// stuff successful login into database
session_write_close();
header('Location: a3.php');
exit;}
else {
$_SESSION['errmsg_s']=Re-enter your email;
unset($_SESSION['email_s']);
session_write_close();
header('Location: a1.php');
exit;}
?
a3.php:
?php
if (empty($_SESSION['email_s'])) {
session_write_close();
header('Location: a1.php');
exit;}
$email = $_SESSION['email_s'];
echo 'Hello there,'.$email.'. We are glad to have you here.br';
?
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?
(P.S. I'll get to the issue of rearchitecting this via require instead
of using header() redirects,cough, cough, Richard Lynch, cough, cough

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.

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.

[PHP] Writing text into images, and setting text size
PHP List, I've been able to write text into an image using the default fonts available, with this command: ImageString($image, 5, $x - 20,$y-10, $text, $textColour); The problem is that the font that is identified by the index 5 is too small. But it seems that it can't be scaled in any way. 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? 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.

htdocs directory. Added at the beginning of the php file:
require_once 'HTML/BBCodeParser.php';
and at the wished output:
echo TD bgcolor='yellow';
$parser = new HTML_BBCodeParser(parse_ini_file('../BBCodeParser.ini'));
echo FONT face=$FFACE color=$FCOLOR;
echo $parser-qParse($DB_DETAIL);
echo /TD;
I tested the input of my form with:
[list] [*]normal [*][b]bold[/b] [*][u]underline[/u] [*][i]italic[/i]
[/list]
The database field in got these data, but the output on the screen is
also just:

What am I doing wrong?

For all of you with an upload/access page to your site that is world-viewable I have made available copies of scripts that kiddies have tried to use to take over my own server. As my upload page has yet to be broken nor my site taken over, I wanted to share them with everyone as a way to learn how kiddies are trying/doing things as well as educating everyone on what they need to do to secure their own site. The specially hardened site for the scripts: http://ambiguous.dnsalias.net/ A long time ago I saw a post about how to lock down your server, if I can find it, I'll post it. But until then, go through the scripts and poke around on your own development sites and see if you can lock your own system down.

in a general way ,
$obj = new User();
specially, I need to assign a Object via a class name .
Now , my code :
switch ($className)
{
case User:
return new User();
break ;
case Item:
return new Item();
break ;
default:
break ;
}
I think that It's not a clever job. How to do it skillfully?
