Handling Form

[shila romualdo]

Guys,
Im trying to pass a single textfield value from one form to another
form in another page. Every time I hit submit the value disappears as
it goes to the next page.. How would I pass and retrieve the value?
Any help would be great.. Thanks..

It should be in the params. Just check your params in your controller,
assign it to a variable or something like that

def new_form
@passed_on_value = params['name_of_that_field']
..
end

then in your view

...
f.text_field :passed_value, :value => @passed_on_value
..

Something like that :)

thanks for the input.. i've tried putting the params in a variable but still when i passed it to the other form the value disappeared.. here are my codes:

view:
<div class="form_row">
            <label for="regnum">Register Num:</label>
           
            <%= form.text_field :regnum, :size => 30, :class => "textInput", :value => @passed %>
           

        </div>

controller:
def edit
@passed = params['regnum']
@something = Something.find_by_reg_number(@passed)   

 
end

Try pasting your code in pastie.org - the first form, the controller/s
handling them, then the 2nd form. :)

another way is to use sessions.

def controller_action #for the second form

  ...

  if params[:value_from_first_form]

   session[:value_from_first_form] = params[:value_from_first_form]

  end

  ...

end

<%= form.text_field :regnum, :size => 30, :class => "textInput", :value => session[:value_from_first_form] %>

this way, you can check if the passed value has changed, coz if it does, it will change the session's value too

which will be consumed by the next form.

view:

<% form_for @somthing, :url => edit_something_path(@something) do |f|
%>
<%= form.text_field :reg_number, :size => 30, :class => "textInput"
%>
<% end %>

controller:

def edit
@something = params[:something] ? Something.find_by_reg_number(params
[:something][:reg_num]) : Something.find(params[:id]
end
