Re: Fwd: [PHP] newbie: problem with $_Post[]
Hello
Richard, that is exactly what I was looking for. thanks alot
Paul, I didn't know its possible to use error_reporting(), that's a good
hint thanks.
btw if you guys know any simple php application that I can study and learn
faster than going through books please let me know. I tried Wordpress but
its too complicated for a beginner like me.

Arash,
It's hard to respond when it's unclear exactly what you want to do.
I'm guessing that you want to simply have the same page show both the
form, and also process the form, so that you can cut down on the
number of pages you have to create.
The way I do this is by first checking to see if the $_POST array has
been set; if it has not been set, then I know that the form wasn't
filled out, and so the script needs to print out the form. If the
array has been set, on the other hand, then the script can process the
form data. Here's a real quick example of what I mean:
if (!isset($_POST)) { ?> // The $_POST array is not set, so display the
form
username :
password :
Hope that helps.
Richard's right. This is the best way to do this.
Your original code had two problems. First, you're getting the error
message because you're allowing E_NOTICE level error messages. You can
turn these off with the error_reporting() function.
Second, as written, your page paints the form and then directly tests
the status of the variables before the user can respond; the whole page
of PHP code executes and then waits for user response. It's only when
the user responds and the page is revisited that the variables can
legitimately be tested. That's why Richard's method works. The
variables are only tested when the page is re-entered after the user
responds.

Re: [PHP] clean url problem .htaccess
what if I don't have access to server to enable mod_rewrite like a hosting, is there anyway to work around? just don't want to build entire website and finally can't get a hosting to enable mod_rewrite for me.

[PHP] header problem
hello
I recentrly uploaded my project from localhost to a hosting and found many
errors and warnings which didnt have in local. one of the most annoying one
is header('Location xxx').
I have used header to redirect users from pages, and kinda used it alot. i
know about the whitespace causing warning, but most of the pages i'm sending
users got html and php mixed so i'm confused about how to remove whitespace
in a html/php file. the error is :
Warning: Cannot modify header information - headers already sent by
here is a simple example, user update page :
if($valid)
{
$msg='111';
$user->dbupdate();
header("Location: /admin/index.php?msg=$msg");
}
else
{
foreach($errors as $val)
echo ''.$val.'';
}
and on admin index i get $msg and display it.
..
//lots of stuff
';
break;
case '421':...
}
?>
// more html and php
how can i fix this?

Re: [PHP] header problem
is there any alternative to header() for redirect users?

Hi Blueman. As soon as ANYTHING has been drawn to the browser, you cannot
use a header command. So you need to work through all of your code, and
ensure that all of your logic that could result in a header call is run
BEFORE you send any html code. Is going to be tricky if mixing html and
php calls.
