A Global Issue
 
I have said it before, that it is so important for us to remember, when talking about matters to do with the Net, that we are dealing with the World Wide Web (with stress on "World".)  It is so easy for us to become insular in our thinking and forget how different things might be in other parts of the world.
 
Take, for example, the discussion that keeps cropping up here in the United States concerning Sales Tax.  Unlike Europe and various other parts of the world, prices in stores here are quoted without the tax.  The tax is added on at the register.  The percentage to be added depends on where you are.  For example, the State of Florida, where I am, imposes a Sales Tax of six percent.  Individual Counties and Cities within the State, however, may also impose a "Local Option" Sales Tax.  Thus, if you are in a County in Florida which imposes a 1% tax and within a city which imposes half a percent, you would pay a total of 7.5%.  All very complicated.
 
Actually, it's worse than that!  Technically, you owe the tax according to where you live, not where you make your purchases.  Retail stores will charge the tax according to where the store is located, however, since they really don't know where the buyer lives.  Unless, that is, they  buy by mail order.  A store in one state sending an item to a buyer in another state (where the store has no branches) will not collect the tax for that buyer's state.  Instead, the buyer is supposed to get a form from their State, declare their purchase and pay the sales tax, which, of course, they always do!  (Yeah!!)
 
Enter the Web!  Lots of people buy all kinds of things from Web Stores.  This is somewhat like a super-mail-order scenario.  It is so easy to find and buy stuff over the Web that the States (and 6,000 odd other taxing authorities in the U.S.) are worried that they are losing money....  and so the first mentioned discussion, namely, let's make a law that says that people selling stuff over the web have to collect the tax for the buyer's taxing authorities.
 
If you think about it, you will realize that this would be complicated enough to put most Web entrepreneurs out of business.  Knowing how much to charge the buyer is bad enough, but what about filling out the returns to send the money in?  How about enforcement?  Altogether this could create a bureaucratic nightmare (or dream, as it may be to a bureaucrat!)
 
But, as I first indicated, the Web has another wrinkle to throw in.  It is World Wide.  How would any one government control what a seller does or doesn't do, as far a tax collecting is concerned, in another country?  Not only that, but what should happen if a retailer in one country sells to a buyer in a second country, but buys from a wholesaler in a third country and has it drop shipped to the buyer?  This happens more than you might think.
 
Yes, the Web is capable of making things extremely complicated in a real hurry!  I love the saying that I've seen hanging on the walls of offices that says "To err is human; to really foul things up requires a computer."


Thanks for reading!

We have had a number of people indicate that their email client programs are interpreting code examples in this newsletter as actual HTML code instead of text.  To overcome this problem and to enable everyone to read the newsletter, there is a period after the "<" in each tag.  If you cut and paste to try out code examples, please remember to remove the periods.  Wherever we intend you to use "<." in your code, the example will show "<..".  In this way, you will be safely able to use a global edit to change "<." to "<".  Thanks to all of you for your patience with this; if this technique creates an undue problem for you however, please let us know via our feedback address (see Feedback, below).

Q. I'm trying to implement Joe Burns' shopping cart onto my webpage and it's working great so far. However, instead of having an 'Add This Item To My Total', and then a 'You Have Ordered This Many Of This Item:', I'd like to have a dropdown menu listing various numerical choices and then an 'Add This Amount To My Total' button. I'm trying to figure it out, but I'm not getting very far. How do I go about doing this?
 
A. It sounds like you want to fill in the number with an option list, and find another way to store the value. I'm not familiar with that cart, but it sounds like a serious reworking of it. It might be a lot easier to find a shopping cart that works the way you want rather than trying to rework this one, though you would learn a bunch of JavaScript in the process. Replacing the text box containing the total with an option list is easy. The user sets it instead of the function setting it. However,
the function that fills that box in Joe's script also stores the variable, and you need to find another way to do that. That's the part that's a serious rewrite.
[As an option, check out http://www.JavaScriptSource.com -- as search on "shopping cart reveals some interesting options.  Also check out Bob Conley's suggestion, below.  - Ed.]

Q. I am starting to design web-pages and wanted to know what would I need to start a small e-commerce site.   I want it to be database driven.
 
A. First you need to know if your server supports database driven sites and if so, what type. If your host uses a UNIX server then it should support PHP and PERL. If your server is a Windows server then it supports ASP. Once you figure which one, you can then look for a shopping cart that will work on your particular server. Your host may even offer a cart for you to use. Ask them first. The next is to start testing cart available on the internet. Do a search on Google and then test drive them. Make a list of what you might want in a cart and see which ones offer what you need.
If you do not want host your own shopping cart, you can look into something like Paypal (http://www.paypal.com ). HTMLGoodies has a tutorail about Paypal here: http://www.htmlgoodies.com/beyond/paypal.html
They do all of the shopping cart work for you. You add some code to your site to use thier cart. They do get a percentage of the sale but I am not sure how much.

Q. I want to add a link on my pages that would allow my visitors to go back to the last page they were looking at, no matter which page it was (like the "Back" button, but a hyperlink).  How do I code this?
 
A. You can use a piece of javascript that works just like the browsers back button. Code it like so:
<a href="javascript:history.go(-1)">Go Back</a>

Q. Do you use href to open a link in a new window?
 
A. Yes you do. You add the target="blank" for a new window. Code it like so:
<a href="http://www.somewhere.com" target="_blank">Somewhere</a>

Q. My server supports CGI, PERL, PHP & MySQL, but not ASP.  What is the easiest way to add a shopping cart capability with credit card processing capability?
 
A. You can buy a shopping cart that will run on what your host supports. First check with your host to make sure that they allow uploading a shopping cart. Then take a look at this site: http://php.resourceindex.com/Complete_Scripts/Shopping_Carts/
It has a lot of pre-built carts that will run on a server that supports PHP. They seem fairly inexpensive. Before you buy one, make sure it has everything you are looking for and if possible, see if they offer a demo for you to try.

Q. I'd like to do is create a template (basically a header and footer) so that I can update the top and bottom of all my webpages by only altering one file for each.
 
A. You can use SSI to include a page at the top and a page at the bottom, if your server supports this.  Take a look at this tutorial: http://www.htmlgoodies.com/beyond/asp.html
About half way down the page it explains SSI and include pages.

Database Record Highlighting ASP.NET Sample Code
 
When I started trying to implement last week's database row highlighting sample in ASP.NET, I naturally looked for a simple and elegant solution. When I was unable to come up with one easily, I went to the web to find one. Well I found plenty of answers, but none of them were very simple, let alone elegant...
