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>

</HTML>

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).
