Hello all, I have a little dilemna here: I am using php/css/mysql to generate a hierarchical table of categories and sub-categories and sub-sub.. Etc.. A screenshot can be found here: http://www.internet46.fr/mehim/screenshot.jpg Now i'm also using javascript to hide show blocks of divs to hide/show sub categories.. Typical.. My issue is on page reload, i have a form on the same page, when a category is clicked, the categorie info displays and you can update the info through this form (table and form on same page). My issue comes when i post the data, the page comes back and my category tree folds up which is normal because all divs are set to "display:none;". I have managed to pass a post/get called lastclicked that gets the nodepath of that element and combined with php to generate javascript that will unfold the tree and highlight the last clicked element... I would like to go one step further and save the entire state of the tree, say several parent categories are unfolded and i click a subcategorie to display my form, i want that entire "state" un unfolded categories to be displayed not just the clicked category, of course i can get this state and save it in a javascript array, but my issue is when i post my form how do i pass that state data generated by javascript back to the page, to be able to unfold the tree in the state it was previously? What are the technologies IF there are any and what should i look up to find docs that cover this type of datatransfer ie: javascript->php. Regards, Tim
I think you want to use sessions for this :) Tijnema ps. Maybe you could also use AJAX instead of submitting forms the whole time.
