[PHP] image button problem
Hi, I am trying to create an HTML form that has several image buttons on it and the resulting action depends on which button is pressed. I first tried using but from IE on the PHP side I only get $_POST['test_x'] and $_POST['test_y'] defined. I therefore don't know which of the buttons on the form was actually pressed. I then tried using the The buttons render fine but when pressed I get $_POST['test'] being the HTML code between the tags and not the value="mytest" that I defined. (In Mozilla I get the result as expected). Is there are a better way of doing this? All I want is to know which button has been clicked on the form. (The form has to be method=POST) Regards, -- Abdul-Wahid Paterson Lintrix Networking & Communications ltd.

Hi, > What do you mean you don't know what button was pressed? You have 'test_x' > and 'test_y' so you know the "test" button was pressed. If you give the > other buttons a different name, you'll have different _x and _y variable > names, so you can still tell which one was pressed. Yes, I should have specified more accurately. I have quite a few of these buttons on one page (approx 30) and really wanted to have the same name="" for each one and only the value change. The reasoning for that is most parts of the page are generated from cached content due to heavy processing requirements on making the whole page. It is therefore quite difficult for me to change it to something like a series of name="test1" and name="test2" for all the buttons as the form being POST'd to would have a hard job trying to work out which names were valid for the POSTing form.

In basic authentication the password goes across the network in plain text and the server therefore has a choice in how it stores the password. There are different ways of doing this usually involving a). DES b). md5 both injected with a bit of salt. Different implementations use different amounts of salt etc. Anyway, the function you are looking for is probably crypt: http://uk.php.net/manual/en/function.crypt.php Regards, Abdul-Wahid -- Abdul-Wahid Paterson Lintrix Networking & Communications ltd.

Why don't you do:
readfile($filename);
straight after your header statements. That will read in the file and
pass it straight through to the browser.

RE: [PHP] random letter/character?[Scanned]
Hi,
It is not a good idea to seed the random number generator inside the for
loop. It should only be seeded once during the execution of a script.
Your function could be susceptible to time attacks as it may not be
difficult to guess the seeding pattern and hence guess what random
numbers were actually produced (in this case always the first random
number in a given sequence).
Also, note from the documentation
Note: Since PHP 4.2.0 it's no longer necessary to seed the random
number generator before using it.
Regards,
Abdul-Wahid

RE: [PHP] random letter/character?[Scanned]
BTW,
This is one of the functions I use you might find it helpful in trimming
down your function.
function gen_password($length = 8) {
$chars =
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
for($i = 0; $i < $length; $i++) {
$x = rand(0, strlen($chars) -1);
$password .= $chars{$x};
}
return $password;
}

Peer review is the best way we can improve our programming. It is good
to post code so that we can all get a better understanding of better
techniques and tricks.

Re: [PHP] register_globals per virtual host
Hi, I think you want to use: php_value register_globals Off I have this setup in VirtualHost's and in .htaccess files. The difference between php_value and php_admin_value is that php_admin_value can not be overridden in a .htaccess file or VirtualHost. So if you want to enforce some settings and allow users to change others you can force them with php_admin_value. -- Abdul-Wahid Paterson Lintrix Networking & Communications ltd.

If then they don't have the cookie set you would know that they have linked to the page directly rather than from following a link on your site. The cookie would have to be some sort of random identifier that you also stored on the web server somewhere so that you could validate the cookie was authentic.

[PHP] after postgres upgrade - ERROR: current transaction is aborted
Hi, I have had a site working for the last 2 years and have had no problems until at the weekend I replace my database server with a newer one. The database migration went like a dream and I had the whole db changed over in 1 hour. Since the upgrade I have been getting the following error message sporadically. ERROR: current transaction is aborted, queries ignored until end of transaction block I have the following setup Webserver: Apache 1.3.27 (Redhat 7.2) PHP 4.1.2 Database server (old): Postgres 7.1.3 Database server (new): Postgres 7.3.4 The PHP scripts have not changed. I am using PEAR::DB for database access. I think it is the PEAR::DB that is actually making the transactions because some times the error message some times gets generated when I don't even have a transaction. Not too sure about that though. The funny thing is, when I first start up the web-server I don't get any error messages and the site carries on working fine just as it did when using the old database server. However, after about an hour. I suddenly get 10 errors a minute from my site (average of course) with the majority of pages still accessing fine. After a bit more time, this doubles to 20 errors a minute. If I carry on leaving the site, I eventually get error messages every second. The error message seem to be generated from completely unrelated bits of my code. When I restart Apache the error messages go away and the site functions as normal. My theory is, since I am using persistent connections in PHP, a connection is some how becoming...unstable...for the want of a better word. That connection then returns an error on every single request. To put my theory to test, I have turned off the persistent connections on my site and everything appears to be working fine now. I now need to work out where to go from here as my server load is high and I would prefer to use persistent connections. Has anyone experienced any similar problems with changing Postgres versions? Do I need to upgrade my PHP on the web-server as the RedHat postgres the PHP was built against was Postgres 7.1.3? Anyone have any suggestions on how I can fix this?

Re: [PHP] how to redirect ?
What errors is it giving? It should work fine. However, remember that since it is part of the HTTP header information it has to come before any of the main output of the script. Do you have a code sample and the error message?

Re: [PHP] Parsing HTML files
No easy way of doing it, regex somthing like:
$id = preg_replace("/.*/", $1, $string);
where $string is a line from your input'd HTML page
