Need to import a CSV from a web form. Only javascript can be generic or YUI.
Once uploaded the file must be imported into mysql then the table cross referenced against another table. Items not matched up must be marked invalid.
On the web page after upload should be displayed
File_uploaded invalid_item_count valid_item_count
File_uploaded should be a link to the file displayed with form fields. The invalid_item_count link should be to a form displaying the invalid items. Then the valid_item_count listing the valid_items. Each item should be in a form field so they can be edited and submitted back to the DB.
I need this very quickly in the next 12 hours and I have more work for you over the coming months. If you can do this form tonight then I will add some other forms for you to give you more hours.
