How to pass data from a view to a controller?

[eluser]theciman[/eluser]
What I meant is I am using a form_hidden which gives me this problem. Once I change the form_hidden to say form_input then everything works fine. This is why I think there is something wrong with the form_hidden function. I am questioning whether one can pass a value to a controller using $this->input->post coming from a form_hidden function. I am told I should be able to pass a value but it does not seem to work. The value is correct in the html code I show above but yet the post shows nothing. Once I make the form visible like a form_input than the value is captured by the post method and I can view it, modify it, and use it to insert values into my database.
