I need this: FRONTEND Form to be filled in with - General personal data of the user (name, address, phone etc.) - Choose the condition if Member "YES or NO". If Member is "YES" a field for entering card number appears. - Choose from a list of topics to which you want to participate (eg Nature, Animals, People, Travel ... are max 6 themes). Each theme has an entry fee. If "YES" member the cost is lower (lower-price discount) - Attach one or more files with a maximum size of 2mb each, attachments must be shown with thumbnail and option delete attachment (X). Attachments must be sent to a folder on the server. - Make the total to be paid, sum of the chosen themes - Accept privacy information and contest regulations - Send the form to one or more email administrators of the site with a summary of all the data of the member including links to the attached photos - Send the user to pay on pal BACKEND - The administrator must see the list of all the subscribers with all the data on the form including links to the attachments, plus the status of the payment, if completed the data of the paypal transaction. - The administrator must be able to export the registered data in files for excell You can also use existing plugins and modify / configure them to do everything I need.
