Small PHP/mysql enhancements to my site.

Need a couple small enhancements of php/mysql to my site. [login to view URL] ## Deliverables I have just started the project myself as I know a little php. What I need is a product popup page (which I have already created) which will popup once each session while a user is logged in. My site is a link surfing site so the user will be surfing links then at a random time between 5 and 20 my popup page comes up with a Special offer to buy a link cheaper than normal price. On that popup special page they will see the offer then if they wish to go ahead with it, they click a button to take them to a payment page where they add their Title for the link and url. After they complete the details of title and url, they will be taken to paypal to pay. (this is already working). I need some php to stop the user from being able to get a special price if they book mark this product page. So if a user bookmarks the page and comes to it the page will just show normal costing price. So this part of the project above is very simple, just a couple lines of code. The next part of the project I wish to place 125x125 banners down the left side my main page on the site and place a link so users can Rent Banner space and pay by paypal. What we need here is: Code to allow user to include Banner url, and location url. Select from a drop down box how many days they wish to list banner for. eg; 7 days = $5 , 14 days = $8, 21 days = $12 and 30 days = $15 I will be able to create this php page to collect this information. I will create a table in db to store needed information such as: user_id, banner_url, location_url, date_added, cost, number_of_days, banner_status, payment_status, banner_clicks, emaill_offers You will need to create the code to store the information and then parse the information to the paypal IPN I already use on the site to take payment for 24 hour Post Ads on right of page. Check to see that paypal payment was a success and then publish the banner. Code will need to be written to allow for multiple banners to be displayed down the left side column so a while loop will handle this. A line of code is needed to check for expired banners an unpublish them and then send an email to member to advise them their banner has finished being published and offer them a one time special to renew banner ad at a discounted rate. So some code to email will be needed and some template email offers to be written in the code. You will not have direct access to my server, so you will need to be online working with me and I will upload the files as you have finished each section of code.
