My application is moving through a few screens of forms and all was going well until i got to the last one.
I have a function in the myform controller:
Code:
/*======================================================================*\
Function: showdropdownform($htmlfile)
Purpose: Grab a FORM out of a html file located on local server
Input: the path to the html file
Output: A drop down FORM
\*======================================================================*/
function showdropdownform($htmlfile)
{
$this->load->library('snoopy');
$this->load->helper('file');
$string = read_file($htmlfile);
$this->snoopy->results = $this->snoopy->_stripform($string);
$data = new Snoopy();
$this->load->view('raceform_view', $data);
}The raceform_view simply shows the form i stripped out of the html file, and the form action is to invoke another controller raceform/index where the user's choice from the dropdown menu is transferred to a function that is supposed to open up the exact same html file: $htmlfile referenced previously in the other myform controller function showdropdownform.
Can i pass along the variable $htmlfile thru the raceform_view and to the next controller some way?

Solved by passing the information in a hidden field in the form:
Code:
<input type=\"hidden\" name=\"htmlfile\" value=$htmlfile>Not a particularly good solution as the full directory path to the file is shown but it gets the job done.
