 Re: How to use a ... figured it out.
Finally got the pieces to work together. For those of you who know what
you're doing, the following falls into the 'duh!' class. For anybody
else new to the game, I hope this helps.
Todo:
Disconnect the MySQL session.
Figure out a way to pass the db connection to the 2nd file rather than
reconnecting.
Convert everything to functions where it makes sense.
Play with other other form construction - embed php in html rather than
embedding html in php, figure out other methods to pass data between php
and html.

Two files, both php.
First one returns a list of sites and launches the second form.
The second one uses the selected site name to return the password.
File 1:
<html>
<body>
<form action="getpw.php" method="get">
<?php
// connect to db
$db = mysql_connect("localhost");
mysql_select_db("test",$db);
$dbtbl = mysql_select_db("test",$db);
// build query
$sitequery = "SELECT site from sitedata order by site";
// generate result set
$siteresult = mysql_query($sitequery);
// use results
echo "Select a site from the list below: ";
echo "<br><br>";
echo "<select name='website'>";
while($siterow = mysql_fetch_array($siteresult))
echo "<option
value='".$siterow["site"]."'>".$siterow["site"]."</option>";
echo "</select></td>";
?>
<br>
<br>
<input type="submit" />
</form>
</body>
</html>
File 2 - getpw.php
The site you selected is <?php echo $_GET['website']; ?>.
<br>
<br>
The password is
<?php
// connect to db
$db = mysql_connect("localhost");
mysql_select_db("test",$db);
// build query
$pwquery = "SELECT password from sitedata where
site="."\"".$_GET['website']."\"";
// generate result set
$pwresult = mysql_query($pwquery);
$sitepw = mysql_data_seek($pwresult,0);
while($sitepw = mysql_fetch_array($pwresult))
echo $sitepw["password"];
echo "<br>";
echo "query is ".$pwquery;
?>
