I have a drop down in one of my views, allowing me to select the number of images on the page. I want to remember the selection on that page, so when the user comes back, the number of images displayed are what they selected last time around.
To achieve this I am setting the cookie value from within the controller like this
if cookies[:per_page].blank? cookies[:per_page] = "50" # this is the default value for a new user and incase the existing user deletes the cookie else cookies[:per_page] = params[:noofimages_perpage].to_s # this is the value selected in the drop down end @pp = cookies[:per_page] # further processing with the cookie value here end
But I don't get the value in cookies[:per_page].
For checking the value in the cookie, I added this line to my view
<%= @pp %>
and the view displays the value only after a refresh.
A Part of the view is here
<select name="noofimages_perpage" onchange="call the controller">
<option value="50">50</option>
<option value="100">100</option>
<option value="150">150</option>
</select>
After reading a few posts and articles, I understand that cookie write won't be available until the subsequent postback.
Some pointers on how to handle this or a work around please?
As far as possible I want to achieve this without touching the database.
Many Thanks
