if else question

Jon501

I am an Ultra Newbie! and have a question.

I need to make a modification to a PHP driven shopping cart. The problem with the cart is that it charges sales tax to every state and country, that's bad!

What I want to do is have it only charge state X sales tax. The line that cart uses to charge sales tax is:

$pre_total_tax = $cart_total * ($site_tax/100);

$site_tax is the tax rate pulled from the database ex. 8.25

How do I add a if..else to this so that if $state == X then $site_tax/100. If $state does not == X then "0"?

I should also make it sensitive to state variations a user may type, ex. FL, Fl, Flordia, FLORDIA. I would do a drop down for the state but I don't want to limit myself to just the US.

"If..else" is probably not the right command but I hope my objective makes sense.

The whole thing sounds do able I just don't know enough to look at it properly.

you pretty much said it in words

basically have it like this

assuming $state is the variable

if ($state == "yourstatename") {
   //this state must pay a tax 
   $pre_total_tax = $cart_total * ($site_tax/100); 
} else {
  //lucky states here do not need to pay the good ol tax
   $pre_total_tax = $cart_total;
}

planetsim,

Shouldn't the else statement be

else { $pre_total_tax = 0; }

Otherwise the tax seems to be the full amount of the cart?

$pre_total_tax = $cart_total * ($site_tax/100) * ($state == "whatever");

would be another option, assuming I understood what $cart_total is.

Wow! Thanks I am going to try it out.

I see what I was doing wrong too!

I'll try it out and get back to you.

Should I do "elseif" to catch user variations of the state "ex. AR, Ar, ar, arkansas, ARKANSAS"?

I wish there was a way to force the US customers to enter it a certain way.

Instead of allowing them to enter the state in a free text field, constrain it so they have to select from an option box - then you only have discrete values. The only checking you would need would be for international, AFPO etc.

Worked fine! Njm you were right on the: else { $pre_total_tax = 0; }

So I can be clear I should do an option box for the US STATES with AFPO and International as options too.

Then I should probably add a new field so that AFPO & International customers can enter their Provence, etc.

Is this do able? A dynamic dropdown list so that when the user selects their country, it triggers the options for the state menu. If they select US they get another drop down where they can pick their state. If they select anything else, then they get a text box to key it in.

I've been looking all day and haven't seen anything like that.

Thanks
