Thanks in advance for your help. You can encrypt the access credentails using some public key encryption technique like RSA and then decode it inside php before connecting to db... But still you have to store the private key in plain text somewere... OR may be you can use 'hard to guess substitution ciphers' [i dunno if tht exists] or create an encryption logic of your own and then use it to encrypt the dataabse uname and pass.

be exact the code is as follows:
if ($count=='1')

session_start();
$_SESSION['user']=$user; // $user is the $_POST['user'] from the login

}
Now what i would like to know is how do i make my website save new changes
the user made while in their account?

You will have to store the user account related data in the database for
persistence Or if the site not having a 'user account system' you may
use cookies to store the settings...

[PHP] Report generation as pdf and csv in php application for huge record set
Hi all, I have an erp application developed in php (zend framework actually). There are many reports which the admin level users can take from the application. Some reports have more than 600,000 records. The viewing of reports in the browser is fine as i have paginated the result. But when it comes to exporting the entire report as pdf and in excel format, im in trouble. I use fpdf for pdf generation and a custom class for converting result to excel. Both these fails when the number of records exceeds 500. Now i have pagianted the report generation and users can download the pdf page wise. But that is not the exact requirement. Im in need of a tool to generate pdf and excel(or csv) for large data set. I came across http://www.htmldoc.org/when i googled for one. Has anyone in the list has faced a similar problem. How exactly is report generation possible when the number of records is extremely huge? Is there a good solution which can be implemented in php? Please help. Midhun Girish
Re: [PHP] Report generation as pdf and csv in php application for huge record set
Hi, - Browsers generally have a 5 minute time-out. If you send the PDF directly to the browser and reach the limit, it will be lost. It is therefore advised for very big documents to generate them in a file, and to send some data to the browser from time to time (with a call to flush() to force the output). When the document is finished, you can send a redirection to it or create a link. Remark: even if the browser times out, the script may continue to run on the server. http://www.php.net/unsub.php When it comes to the user end, they wont wait for more than 1 min. So redirection after generating the report is not possible. But creating link may be a good idea. How can it be done? I mean shouldn't there be a service running in the server to process these request after the execution of the php script is completed? Also shouldn't we post all the report generation request to a database so that serial processing can be done?

Hi Dan
One method for this is to use URL Rewriting (which can be implemented on
Apache using htaccess).
Through URL Rewriting you can first make the following URL:
http://www.website.com/article-clean-url
http://www.website.com/article-clean-urlto internally behave as the
following:
http://www.website.com/index/user/ http://www.website.com/index/user/11
http://www.website.com/index/user/1and then you can use the same

Hope this helps.

Re: [PHP] image upload keeps file name ?
I use the follwing function for moving files:

$fileName = $file['name'];
$ext = substr($fileName, strrpos($fileName, '.') + 1);
do
{
$targetfilename=md5(date(m.d.y.h.i.s).basename($fileName)).'.'.$ext;
$fullname=$targetdir.$targetfilename;
}while(file_exists($fullname));
move_uploaded_file($file[tmp_name],$fullname);
return $fullname;
}
Call the fn as :
foreach($_FILES as $file_name = $filearray)
{
if( $filearray['error']=='')
{
$filenametobestored=moveFile($filearray);
/*Enter name into db here*/
}

I think what you want is something to trigger a php script every $period-of-time; if your host supports it, cron is the means of executing an application at regular intervals down to a minute granularity.

Re: [PHP] Re: Event Handling
ok so we have a script which checks if any cars have arrived within last 10 minutes... if yes, a mail will be send. suppose the server fails for 30 minutes so when the cron comes next time, we will have to check for cars which arrived within last 40 minutes and not 10.. right... so how will we set a time limit in the script? its variable na.. but the flag is ok.. you can send a mail to all db entries which have flag 0 and then update the flag to 1.

The web site in its basic form allows users to send cars from a point and then the car will arrive at another point. When the car is set on its way, the start time, travel duration and end time are all known and stored in a MySQL database, what I would like to happen is that an event is triggered on the server at the end time and then an e-mail is sent to the user. This should happen regardless of whether someone is browsing the website or not. I don't believe that I'll be able to solely use PHP, I have spent the afternoon trying to look at potential solutions but I have to admit I've drawn a blank. Google hasn't been helpful (64 pages so far), as any searches related to event handling bring up a load of JavaScript tutorials/help for 'onclick' events etc. I have searched through the PHP documentation and found libevent (http://www.php.net/manual/en/book.libevent.php ), I don't believe that is what I require (although in all honesty the lack of documentation on it means I'm quite in the dark as to its purpose). Another potential candidate I came across was a PHP/Java bridge (http://php-java-bridge.sourceforge.net/pjb/ ), whereby I could use the java virtual machine, register events with it and then callback PHP scripts, although this seems extremely long winded. I was hoping that someone might have some experience with this kind of issue and could point me in the right direction. I'm sure I've missed something right in front of me. Alex. I think what you want is something to trigger a php script every $period-of-time; if your host supports it, cron is the means of executing an application at regular intervals down to a minute granularity. There are some web-based cron services also, but they may not have the same granularity as a locally based cron. Cheers -- David Robley Wow! barked Tom, with a bow. Today is Prickle-Prickle, the 1st day of Discord in the YOLD 3176. You could store the end times in the database, and cron can run a script that will check each of these times to find any that are within x minutes that an email hasn't been sent out for. You'll need an extra field to indicate whether an email has been sent or not. Thanks, Ash http://www.ashleysheridan.co.uk Consider a cron script that runs every 10 minutes. You'll want to check the db for cars that are due to arrive within just over 10 minutes. The flag is there more for you own clarification that the email has been sent. What if the cron fails, or you restart your server, or the script your cron calls is just running a little slowly? Thanks, Ash http://www.ashleysheridan.co.uk
Re: [PHP] Event Handling
rene a page with an ajax script that kicks off the check-for-recent-events script on the server.. but that method is highly non reliable i dont think anyone will take that risk especially for an important web app cron or any equivalent which runs on the server must be used instead of that..

Make a script say check.php which checks the db to see if any new entries are made... and if yes send the mail ... now using the cronjob feature in linux os(which will be provided as a service in your linux hosting cpanel), set a cronjob which calls the http://www.yoursite.com/check.php; URL every minute now a trigger will be there every minute to the script and the emails will be send irrespective of whether anyone is browsing the site or not hope it is clear... use cron - yes have cron call a web URL - no, instead just call the script via the php CLI sapi, e.g. a cmdline as follows in cron: /usr/env php /path/to/your/check.php /dev/null I do believe removing the /dev/null will send error messages during the building of the script, correct? the ' /dev/null' redirects all output - I kind of make the assumption that the script would be logging stuff to a file or something when in production. so, yes, remove the redirection when your developing/testing the script.
Re: [PHP] Form validation issue
then the page gets reloaded and clears all the javascript error messages and does the PHP validation. That is because the form is getting submitted... make sure you js code prevents form submit if errors are found Midhun Girish On Mon, Dec 21, 2009 at 8:13 AM, Ernie Kemp ernie.k...@sympatico.ca wrote: Good Day, I need help in in validating a form. The for is valdated be a javascript frist then if all the fields are filled in its valaded be PHP. The Form starts with: form name=myForm action=?php echo $_SERVER['PHP_SELF'];? method=post onsubmit='return formValidator()' The “formValidator()” goes to a javascript and does display the missing information in this case BUT then the page gets reloaded and clears all the javascript error messages and does the PHP validation. The PHP only runs if the fields are set by testing using ‘isset”. Without puting on numeric lines of go can you suggest things I must have overlooked. Silly request but there must be something I’m overlooking.I have simular code on other programs but this one is casuing me trouble. Thanks every so much.. ../Ernie
