The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Zones: ColdFusion Application Server, ColdFusion Studio, Cold Fusion Markup Language

Tags: ADOBE, COLDFUSION

Hello experts.
I have a search page and a result page.From here now i want to built a page where a user can <watch> the items he wants like the shopping cart.
The user doesn't have to be logged in.
On the new page i need a button to delete the items that someone don't want to watch any more.
How is this working?Do i need a new table?
(I use coldfusion and MS SQL)

one thing u said u want to delete the item ,what exactly you mean by delete you want to delete the item permanently or you dont want to show to only that particulat user,. ( you said no need to log in to view this page )

if it is like deleting permanently then u can delete from the master table or change the flag to inactive if ur using falgs.

Hello srikanthmadishetti:
I mean like the shopping card.If you don't realy want to buy something you delete it in your basket and than you see the rest of your basket.
In this case i want to watch cars.If i'm not anymore interested in one car i can delete it (from my watching itemspage ,Not from the DB)

Zvonko:

You need a new table. The table primary keys are the user key and the item key (the wached item). Additional columns could be whatchlist item creation date, report creation frequency for that item, and so on.

hi panosms

you want no user log in right i mean user can shop with out logging in and at check out u will ask for the user details.

panosms:

Hello again.
If you go to sites like search cars,you don't have to be logged on to watch items.Looking at mobile.de you will se in the english version that there is a link to :My Park.
Here you send the items from the result page.i think that is working with cookies or session.

Zvonko:

I do not think that all whatchlist data is stored in Cookies, so if not logged in then you are "logged" by a cookie that is generated for you by that web site. As soon as you come again with that cookie you are recognised as former "user" of that page and your old cookie with the generated userid is reused. But all the other information about your visit and your wish list or watch list is stored on server side in some sort of persitant storage, and that is mostly a database.
So your userid in my upper table is the "userid" from the cookie vistor id.

panosms:

well Zvonko.
I have found in one of my books for coldfusion MX the way to to this.
These are 7 files.
I will upload all the files so that they can help another user.
As it is it is working.
When i try to do this with my site i have two problems:
1)In the listarticle page in the query says :Select pkAID as AID.I have in my DB instead of pkAID ->Art_ID.
When i write SELECT Art_Id as AID i get an error.
The second is:
My query is:
<cfquery name="artikel" datasource="#dsn#">
SELECT a.Art_ID,a.Besonderheiten,H_All.Hersteller_DE
FROM dbo.artikel a
LEFT JOIN H_All ON (a.Hersteller_ID = H_ALL.Herst_ID)
</cfquery>
In the shoppingcard.cfc is in the query :where TArticle.pkAID in(
<cfloop collection="#this.strCard#" item="AID">
#AID#,.......
How can i have the Left Join and the WHERE ...in the query:
