Hello David,
I've added fields to add shipping and tax to my site.
For tax, I have 2 fields (state & tax). I put this in the tables by seperating each state and tax percentage by a comma (,). I want to include a $_POST["myState"] for the user to select from a drop-down box and then the appropriate tax amount will be displayed.
One merchant has the following fields:
state = IL,WI,IN,MI
tax = .0825,check site,.06,.06
I was going to explode the state and tax variables by doing this (in html/prices.php) for each merchant:
<?php
$state = explode(",", $product["state"]);
$tax = explode(",", $product["tax"]);
?>
But I don't know how I can compare the $_POST["myState"] value with each state, and then if a state does match, it'll pull out the correct tax percentage.
You can see what I've done so far on this page:

Thanks for your excellent support,

Hi Michael,
What you can do is use PHP's array_values() function to extract the two arrays that you've created using explode() into numerically indexed arrays, and then combine them to give you a associative array indexed by state.
Here's some example code based on your variables:
<?php$product["state"] = "IL,WI,IN,MI";
$product["tax"] = ".0825,check site,.06,.06";
$state = explode(",", $product["state"]);
$tax = explode(",", $product["tax"]);
$state_values = array_values($state);
$tax_values = array_values($tax);
$tax = array();
foreach($state_values as $i => $state)
{
$tax[$state] = $tax_values[$i];
}
print_r($tax);
?>
You will see that you can then index $tax with the value of your $_POST["state"]. What you would want to do is check whether a value exists for the users' state, and then display it if so, otherwise default to "check site", for example:
<?phpif ($tax[$_POST["myState"]])
{
print $tax[$_POST["myState"]];
}
else
{
print "check site";
}
?>
Hope this helps!
Cheers,
David.
