Jquery for forms and mysql with php

1. I was adding a form so on post the form data is submitted but the page does not reload using jquery. But this was not working, so this needs to function. It should open a message to the user and write to the database. Before this writes to the db the post data should be compared and validated. 2. The css on a bottom footer is off with the width. This is called from a css file and affects certain screen resolutions, this should be consistent for all resolutions and browsers. 3. We have a Broadcast feature which allows a page to promoted on twitter. I had to remove what called the social media link that loads, so this needs to be restored in a new layer. When the link to broadcast is clicked the form should insert in a table and at least one field should be required. There should be a checkbox that can be clicked to prevent writing to the db.
