You could yuse it only when you have a value
$sql_where = '';
$get_data_query = "select a, b, c from table ";
$sql_orderby = "order by $sort_field $sort_order";
if (isset($_REQUEST['state']))
{
$sql_where = " where state = '" . $_REQUEST['state'] . "' ";
}
$sql = $get_data_query . $sql_where . $sql_orderby;
$result = mysql_query($sql);

That sounds like it, but help me a step further as I work from a template
and haven't fully absorbed the syntax. My basic query is:
$get_data_query = "select a, b, c from table order by $sort_field
$sort_order";
Where do I put the syntax you suggest? Where do the words go on which to
click to execute? Also, I forgot that I'm using is zip codes to define
states, so I'm doing, for example, 39999 > z > 29999 Thanks

Sounds like you just want some pretty basic variable substitution? As in
the page is submitted with, say, state=T and you need to code your select
statement like eg:
$query = "SELECT * FROM tbl WHERE state = '".$_REQUEST['state']."'";
then execute this query in your DB call.
Does that help?

How do I write a link which results in a page with part of the data in
the mysql table and do that multiple times on a single php script page?
That is, I want to be able to click on state names on a single page
and bring up a page with only that state's data. I understand use of
the "where" limitation, but I don't see how to code a line which will
override the base "select" statement for the script. Thanks.
