Ajax form validation php

1-Need to get rid of the dependent drop downs in listing update page/ add listing page/ search page/s. I had some ajax thing done but never finished completely at: [login to view URL] at the end of each FREE listing (D) there is a link " Cég adatok szerkesztése " which is for updating listing informations. Users do not need to be logged in to update a lisiting. After a user submits the new data it will go to admin and he can approve or reject the changes. the other page were I would like to get rid of this refreshing drop down is: [login to view URL];type=D ... Obviously pages in the admin should be able to handle the new changes.. 2- users can add listings: currently if a users inserts a listing then edits it it does not go to admin for approval and review... I am looking to have statuses for listings similar to what I have for my photos. so lets say: A user registers a listing. Currently in admin I can set it up to be automatically approved or only after admin approval goes online. so lets say after admin approves it then it is published. So if the user edits it i would like to have all the edits go as pending till admin approves it. and till then the original data still show up in the directory. Also if a user wants to delete a listing, he should NOT be able to do that till admin approves that. You can: 1-work on current form 2-use forms from test site 3-build your forms from scratch but please note there is an admin background that still needs to work. Thats it but ask me if you have questions..
