I have a script that displays a random record. (basically selects an ad banner from a database) but i'm trying to figure out how to make a record with a weight of 2 display twice as much as a banner with a weight of two. For example if I have 2 banners one with a weight with 1 and the other with a weight of 2 and the script is run 1000 times i want banner 1 to be displayed approximately 333 times and banner 2 to be displayed 666 times. Does anyone have any ideas? ------------- Paul A Morgan http://www.pmorganphoto.com/" rel="nofollow - http://www.pmorganphoto.com/ |

You can easily use the builtin ad rotator that comes with IIS. Just create a text file like: where the numbers are the percentages. ------------- http://baumannphoto.com" rel="nofollow - Blog | http://mpgtracker.com" rel="nofollow - MPG Tracker |

i think you misunderstood me... what if i want one of those banners to appear twice as much as another. I already have a management program that counts clicks, shows, etc. but i would like to modify the following lines in the banner selection script RANDOMIZE so that a record containing a "weight" on 2 will be twice as likely to appear than a banner with a "weight" with 1 ------------- Paul A Morgan http://www.pmorganphoto.com/" rel="nofollow - http://www.pmorganphoto.com/ |

I did not misunderstand you; I was just saying that e.g. below, the first one would show abou twice as much as the second one. I don't know how your code looks like right now and your db to tell you how to implement it to your existing script. http://www.YOUR_DOMAIN_NAME.com/images/banner3.gif ------------- http://baumannphoto.com" rel="nofollow - Blog | http://mpgtracker.com" rel="nofollow - MPG Tracker |

Or, if you don't want to use IIS's inbuilt rotator, you could simply duplicate the double-weighted banner entry.
ie., you'd have three entries - one for banner 1, and two for banner 2. On a random 1,000 views, banner 1 would get seen around 333 times, as would each of the instances of banner 2. Being identical, banner 2 would therefore get seen roughly 667 times. Bit of a bodge though, when IIS will do it for you! ------------- http://www.pedalcars.info/ - www.pedalcars.info The most fun on four wheels

excellent idea... that pretty much what i need. Banner 2 will be twice as likely to be shown as banner one. Good Idea! ------------- Paul A Morgan http://www.pmorganphoto.com/" rel="nofollow - http://www.pmorganphoto.com/ |
