Displaying category selections in pre-determined to implement Business Directory

[jcimb]

I have implemented the EPC here as a Member Business Directory: http://www.nvfpc.org/findaprofessional.php

Now I would like to list it sorted by business type. So I think I would take the category 'Members' and create selections such as Assisted Living, Caregivers, Financial Services, etc.
To show the list, I would have repeated lines of code where I would change the category ($showCat) then call calendar.php repeatedly such as: (assume for now that other variables would be set also)

<p>Assisted Living</p><?php
$showCat="a|2|6";
$template="mytemplate.php";
require ("calendar/calendar.php");
?><p>Caregivers</p><?php
$showCat="a|2|8";
$template="mytemplate.php";
require ("calendar/calendar.php");
?>etc.

Questions: Is this a good way to implement this?
Would this adversely affect the server by having repeated calls to the database?

You can do it this way. It would depend on your server and if it's capable of the multiple SQL calls in an efficient manner. I think you'd just need to try it to see.
