Help: Input of form 1 to hidden field in form 2?

Rails
1

Hi all I’m new to rails an i’m trying to build a step by step form /
process to gather data. For example:
form one:
User enters a 8 digit number
the submit button points to form 2.

form two:
the 8 digit number from form one becomes a hidden field in form 2.

The problem I have is that the entire hash from form 1 is showing up in
form two rather than just the input data.

example:

form 1:

Step 1

<%= start_form_tag :action => ‘step2’ %>
<%= render :partial => ‘form1’ %>
<%= submit_tag “Register Tag” %>
<%= end_form_tag %>

Here is the partial (form1):

<%= text_field 'tag', 'tag' %>

CONTROLLER:
def step1
@tag = Tag.new
render :action => ‘step1’
end

def step2
@newtag = (@params[:tag])
@tag = Tag.new
render :action => ‘step2’
end

FORM 2:
…

RESULT:
If I submit 12345678 in form 1

I get “tag12345678” in form 2

FORM 2:
Source after Form 1 submit

I only want the digits 12345678.

you’re feeding the whole tag hash into @newtag. try changing in your
controller:

CONTROLLER:
def step1
@tag = Tag.new
render :action => ‘step1’
end

def step2
@newtag = (@params[:tag])
@newtag = (@params[:tag][:tag])

@tag = Tag.new
render :action => 'step2'

end

maybe you should change the name of your text_field name to something
like tag[value]…tag[tag] is a bit confusing:

<%= text_field ‘tag’, ‘value’ %>

-tak.
