This is a search and display script in PHP...you will need a HTML search form and if you need that let me know.
           <?php
 
 
            // declare sting variable and set value to link to theform.html
            
 
            // connect to database and select database 
 
            $con = mysql_connect("localhost","username","password");
            if (!$con)
            {
                  die('Could not connect: ' . mysql_error());
            }
 
            mysql_select_db("directory", $con);
 
            $name = 'name';
            if (isset($_REQUEST['name']))
            {
                  $name = trim($_REQUEST['name']);
            } else {
                  echo "Sorry, no search criteria.";
 
                  exit;
            }
 
            // contains the string input by the user on the name.html page
 
            $query = "SELECT * FROM package '".mysql_real_escape_string($name)."%'";
 
            $result = mysql_query($query) or die( "Problem executing: ". $query . " " . mysql_error() );
 
            // if no results are returned from the query, give error message and exit
            if (mysql_num_rows($result) == 0) {
                  echo "Sorry, no matching results.";
 
                  exit;
            }
 
            while ($row = mysql_fetch_assoc($result)) {
            
 
 
		  echo "<b>Package Name: </b>";
                  echo $row["package_name"] ;
                  echo  "&nbsp;";
 
            }
            ?>
      </BODY>

Have you tried reading the Smarty docs? This is pretty simple stuff.

In your PHP script you need to assign the list of values to your smarty instance:

$smarty->assign('pack', $pack);

Then the contents of the $pack variable will be available inside your template.

The easiest way to build a select menu is to the the Smarty html_options plugin:

thanks Squinky.

i got what you mean.. but cant make my script run..
nothing was shown except the

-- none --



see my code, if i did something wrongly?

if i use

{html_options options=$pack}

it show the whole thing inside table in a long list.

TPL :
 
  <fieldset>
        <legend>Package Management</legend>
            <label for="Package">Package: </label>
            <select name="package">
             <option value='null'>-- none --</option>
             {html_options options=$pack.pack_name }
                                                                           </select>
            <br>
            <label for="gender"></label>
<br>
        </fieldset>
 
 
=====================================================================
 
PHP:
 
 
    
	$sql2    = "SELECT pack_name FROM package";
	$rs2  = $conn->execute($sql2);
	        $pack = $rs2->getrows();
	
	$sql    = "SELECT * FROM signup WHERE UID = '" .$UID. "' LIMIT 1";
    $rs     = $conn->execute($sql);
	
    if ( mysql_affected_rows() == 1 )
        $user = $rs->getrows();
    else
        $err = 'This user does not exist! Invalid user ID?';
}
 
STemplate::assign('pack', $pack);
STemplate::assign('user', $user);
STemplate::assign('countries', $countries);
?>

The item that you pass for options needs to be a simple associative array (where the key name is used as the value attribute and the value is use for the option tag content), and what you're giving it is probably a bit more than that. If $pack is an array of records, then $pack.pack_name is probably an invalid index, hence the empty select.

Preprocess the pack list like this:

$packnames = array();
foreach($pack as $item) {
$packnames[$pack['id']] = $pack['pack_name'];
}
$smarty->assign('packnames' , $packnames);

That should then work in the html_options tag (you may need to tweak field names).
