RE: [PHP] Saving css state in javascript and passing to php via form submit

The weather in here gets stormy easily i see :D Anyways thanks Richard, that's the kind of idea i was orginally looking for, before opting for the ajax way, which is only going to optimize my application more and give me more flexibility in doing what i need. Have looked up javascript and DOM and now understand how to "dynamically" create content from javascript that can later be interpreted by a php form. In any case everyones input was great, got a lot of ideas out of it. Thanks all ;) P.S. Sorry for the delicately on/off topic, was inbetween languages here, and since i'm more familiar with your input i oppted for this list ;) Tim > -----Message d'origine----- > De : Richard Lynch [mailto:ceo@l-i-e.com] > Envoyé : dimanche 1 avril 2007 07:39 > À : Tim > Cc : php-general@lists.php.net > Objet : Re: [PHP] Saving css state in javascript and passing > to php via form submit > > On Fri, March 30, 2007 9:45 am, Tim wrote: > > 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).
