Hi,
Here I have code to display a list of products to display. I use
pagination to display them . 3 records are diaplyed on a single page.
when I move to the next page I actually passes through the controller.
there I want to access previous pages value.
how to do it.
the controller is
def viewsearchitems
@srchparams = params[:txt_srch].to_s
@cnt = 1
page = (params[:page] ||= 1).to_i
tems_per_page = 3
offset = (page - 1) * items_per_page
@prods=RealEstate.find_by_sql("select * from real_estates order
by id")
@prod_pages = Paginator.new(self, @prods.length, items_per_page,
page)
@items = @prods[offset..(offset + items_per_page - 1)]
end
viewsearchitem.rhtml is
<% if @items != nil %>
<% for result in @items %>
<tr>
<td class="SrchTblTxt" align="center">
<img src="/images<%= h(result.imgpath) %>"
height="50"
width="50">
</td>
<td class="SrchTblTxt" align="center">
<%= link_to result.id , :action => ''dispitem'',
:id => result %>
</td>
<td class="SrchTblTxt" align="center"> <%=
result.address %>
</td>
<td class="SrchTblTxt" align="center"> <%=
result.bedroom %>
</td>
<td class="SrchTblTxt" align="center"> <%=
result.area %> </td>
<td class="SrchTblTxt" align="center"> <%=
result.price %>
</td>
</tr>
<% end %>
<% if @prod_pages.page_count > 1 %>
<%= pagination_links @prod_pages %>
<% end %>
<% end %>
if I have checkbox associate with each item in every page How do I get
the status of the checkbox in each page when I move from one page to
another

Hello, you can try this:
pagination_links(@prod_pages, { :params => @params})
Also, @items = @prods[offset..(offset + items_per_page - 1)] equal
with
@items = @prods[offset...(offset + items_per_page)]
:)
