Sandbox

currently i am working with login forum (components/com_register)
Here when any one register as new user then if the username is already entered then currently a message is showing 'This username/password already in use. Please try another.' and returning the previous page all the fields left blank. I want such that when it will return the previous page then all the fields without username and password will be filled by the values just entered.

thanks.

I guess there are a few ways to do this... you could always save the get / post variables to a session var on the error page, something like this:

at the top of the page:

session_start();
$_SESSION['formvalues'] = $_REQUEST; //this will save all post and get variables.

Then you hack the registration form and add the variables to the form values like this:

//top of page
session_start();
extract($_SESSION['formvalues']); //this extracts the $_SESSION['formvalues'] array into variables - eg $_SESSION['formvalues']['myvar'] becomes $myvar;

//hack the form values
[/b]" />

When I use the code It puts the values into an array within the $_session array, so then when I want to get a value out I need to do something like:
Is there an easy way to expand the fromvalues array as I put it into the $_session array so that  I can just use $_Session['risk5']?

be careful with this, it has security nightmare written all over it... one could set any session variable from the url, well maybe... not sure... but be careful

I am just using the $_session variable to store values that I collect on a few consecutive screens so that I can use them to do calculations and create a report.  The program will be similar to one that was written by a professional programmer for me at http://www.freevaluationsonline.com to do business valuations.  He hard coded the name of every variable and I figured there had to be a better way.

Perhaps it's because I'm a real newcomer to this language, but I don't see the risk.  As far as I can tell the $_SESSION variable only contains a SESSION ID and the values that were input on the various screens, which the user picks anyway.  Am I wrong and there's something else in the $_SESSION array or something that's not in it and really shouldn't be.  Is it a Joomla related security issue?  Perhaps I should have posted to PHPBuilder.com, but I found the answer here first.

Thanks,

Well I dunno for sure like I said, but I know for one of my components there are sessions that are set which, if compromised, could cause a significant risk, maybe other components could have problems as well. This is why it would be better to set the session in a sub-dimension of the sessions array as opposed to the root.

But anyway if no one knows the inner workings of your code it's probably not such a risk, but I just thought I would warn you.
