[PHP] Secure redirection?
Hi,
I'm building a login system with AJAX/PHP/MySQL.
I have worked everything out... AJAX is sending request to a php login
script (login.php) who if authentication passes initializes the session and
sends the header using header("Location : registered_user_area.php");
The whole system works great without AJAX, but when I put AJAX in the story
I ahve one problem:
1.When the user is successfully authenticated the login.php sends the
header, but the AJAX XMLHttpRequest call is still in progress waiting for a
PHP response. So when PHP using the header function redirects to another
page that page is outputed to the login form...
My PHP login snippet is:
if ($res_hash == $u_pass) {
$logged_user = $sql_execution->last_query_result->user;
$sql_execution->exec_query("DELETE FROM seeds",false);
$sql_execution->db_disconnect();
session_start();
$_SESSION['user'] = $logged_user;
$host = $_SERVER['HTTP_HOST'];
$url = rtrim(dirname($_SERVER['PHP_SELF']), '/\\') . '/mpls/index.php';
header("Location: http://$host$url";);//--That page
($host$url) is outputed in the login form...
exit();
}
else {
$sql_execution->exec_query("DELETE FROM seeds WHERE id=$row->id",false);
$sql_execution->db_disconnect();
echo 'BLS';//--This is sent when the password/username is
wrong
exit();
}
???
Any help greatly appreciated
Thank you!

Ok, here is one piece of code dealing with this:
$data[0] = preg_replace("/([<])+([^>])+([.])*([>])+/i","", $data[0]);
$data[0] = str_replace (" ", "", $data[0]);
$file = fopen ("data.txt", "wb");
fwerite ($file, $data[0]);
flocse ($file);
As you see, I'm not using any \n for new lines because this code deals with
HTML page.
I guess problem is in new line, and trim() only cuts whitespaces.

[PHP] Removing strange chars from array (or string)
Hi Well, when parsing html page data I want to save is saved in txt file. But when saving in txt file I got some strange chars like small square (this I see when open in NotePad). When I try to open in WordPad this strange chars (squares) are recognized as new lines so in my file I got many empty lines. I've try to trim array (string) before saving to file but that didn't help (tried with trim, ltrim and rtrim). Am I missing something? Regards, Zoran
[PHP] preg_replace question
Hi Sorry for issuing this again, but I need help with preg_replace. I manage to replace certain text between in text with preg_replace but I want for every other to be replaced by other text. By this I mean when some text between has been found that text is replaced with some Text, on second match, text between is replaced by some other different text etc. Btw, where I can find patterns that are valid? (something like (\w+), (\d+)+i etc. Thanks. Regards. Zoran
Re: [PHP] Web Fetch & Process
Hi
How can I parse HTML page which I fetched by PHP so some part of text would
be replaced by other text.
Also, I managed to delete all HTML code from page (with this code
$data[0] = preg_replace("/([<])+([^>])+([.])*([>])+/i","", $data[0]);
but also would like to delete all chars except numbers from page, can this
be done?
Regards.
Zoran
Your first question:
To replace certain elements take a look at preg_replace()
http://us4.php.net/manual/en/function.preg-replace.php
Example:
$foo = 'stuff silly stuff more stuff';
echo preg_replace('/\(.*)\<\/b\>/', "$1 lookie now", $foo);
Your second question:
You could just use strip_tags()
http://us4.php.net/manual/en/function.strip-tags.php
Your last question:
To delete everything but numbers you could $content =
preg_replace('/[^\d]/','', $content);
Hope that helps

Hi
This works great. One more question about preg_replace. Is it possible that for every
match other text is replaced?
By this I mean when some text between has been found that text is replaced
with some Text, on second match, text between is replaced by some other
different text etc.
Btw, where I can find patterns that are valid?
(something like (\w+), (\d+)+i etc.
Thanks.

[PHP] Web Fetch & Process
Hi
How can I parse HTML page which I fetched by PHP so some part of text would be
replaced by other text.
For example, if I have bold text on HTML page (Some text) how can I manage that
all bold text on that page is replaced by some other text.
Also, I managed to delete all HTML code from page (with this code
$data[0] = preg_replace("/([<])+([^>])+([.])*([>])+/i","", $data[0]);
but also would like to delete all chars except numbers from page, can this be done?
Regards.

Yeah! Of course. This was the problem.
Script and text file were in 'mydir/public_html' but I call script from
'mydir' so I script looks for text file in 'mydir' because of $file =
file_get_contents("text.inc");
For the quick test I've changed this to:
$file = file_get_contents("public_html/text.inc");
and now it's working. Thanks a lot!
Regards.

[PHP] Problem sending mail
$file = file_get_contents("text.inc");
$start = "[start]";
$end = "[/end]";
$pos_start = strpos ($file, $start);
$pos_end = strpos ($file, $end);
$data = substr ($file, $pos_start, $pos_end);
mail ("[EMAIL PROTECTED]", "My Subject", $data);
This code works when I call it from browser, but when I call it from command line,
$data is not put into mail
(mail is send but it is empty, without any data in body).
File text.inc looks like this:
[start]some_text_goes_here[/end]
[other_start]other_text_goes_here[/other_end]
Regards.
