Ok to be more specific. I'm writing an extension to collect client's 
information and write it into database. Instead of putting the form 
source code in $content of pi1/class.ext.php I want to use an external 
HTML so that the user of the EXT can collect whatever information he/she 
want simply by providing his/her own HTML form template. Right now the 
code looks like this

function formrender(){
	...
	<input type="text" name="'.$this->prefixId.'[DATA][uname]">
	...
}

function datawriter(){
....
  	$instQury='INSERT INTO '.$this->tablecl.'  (uname) VALUES 			 
("'.addslashes($this->piVars['DATA']['uname']).'")';
	 $result=mysql_query($instQury);
...
}

Another question is that there are several forms(e.g. 1 for collecting 
user's information, one for writing comments for the user etc.) I need 
to render in the front end. Is that possible I can use one HTML template 
for one form. Is this doable?

I'm quite new to EXT development. If any of you could give me some hint, 
I would really appreciate it?

Thanks a lot in advance!
