首先你需要一个数据库放置你的广告,我们共用了2个表: blBanners 和 tblVendors表: tblBanners结构表如下: bID - auto number (广告ID) bBanner - text (图像文件) bUsedViews - number (# 标准的广告显示次数) bTotalViews - number (# of imPRessions the vendor has paid for) bClicks - number (# 标准的广告点击次数) bURL - text (网站URL) bShow - yes/no (用来标识广告是显示还是隐藏) vID - number (卖主 ID)
tblVendors表结构如下: vID - autonumber (卖主 ID - 链到tblBanners.vID) vName - text (卖主的名字) etc..........
Now that we have all of the banners that we can display, we need to display a random one. We can do this by grabbing the total number of banners, moving to the first record, and the moving to a random number, for example:
Now that we have moved to our random banner, we now need to display the banner on our page (I am sure you know how to do that, so I wont bore you with the details). However, Instead of using the banner's URL in the link, we are going to use a redirect page so we can count the clicks. All we need to do is use the banner ID in the HREF tag, for example:
a href="redirect.asp?ID=<%= BANNER ID %>"
Now that we have the link set up, we can move on to our redirect.asp page. On this page, we are going to grab the ID that we are passing in the Query String, and grabbing the RecordSet that matches. Once we have the RecordSet, we can grab the banner's URL, increase the Clicks by 1, and send the user to the destination URL. Below is the code for the redirect.asp page:
<% If Request.QueryString("ID") = "" Then Response.Redirect("default.asp") End If
