smarty template
Question
So here is the problem, I have an index.php (with all the php code) and I have an index.tpl file with all the html stuff. But now because I am using ajax I have another php file that should output some data (data.php). The problem is that I don't know how to select the template in the data.php file, all I know is on the index.php I have a function that displays the tpl ($Smarty->display($filename); ) but I don't want to display the template (again) in the data.php file I just want to assign some variables that need to show on index.tpl
EDIT:
Ok this is going to be long: First I need to explain what do I want to accomplish. I have the index.php and the data.php. The index.php:
<?php
include("../include/config.php");
include("../include/functions/import.php");
$thebaseurl = $config['baseurl'];
$query ="SELECT name FROM contacts";
$results = $conn->execute($query);
$select-names = $results->getrows();
STemplate::assign('select-names',$select-names);
$templateselect = "index.tpl";
STemplate::display($templateselect);
?>
The index.tpl is a little long so I will post the important part:
xmlhttp.open("get","data.php?q="+str,true);
This is AJAX code, this code sends +str value in GET method to the data.php file that then uses the value and pulls some data from the database.
data.php:
$q=$_GET["q"];
$sql="SELECT * FROM contacts WHERE name = '$q'";
$result = mysql_query($sql);
while($row = mysql_fetch_array($result))
{
$name = $row['name'];
}
STemplate::assign('name',$name);
$templateselect = "index.tpl";
STemplate::display($templateselect); //the second display
?>
I use that class here STemplate for the smarty functions, but you get what is the code.
I hope you understand what is the problem now. How can I assign variables to a template without displaying the template file again. This way the $name variable is accessible in the index.tpl (the name is shown from the db) but the whole content is shown again because of the dispaly function in the data.php.

Use $smarty->assign('var', 'value'); to assign values.
For more information read more here .
EDIT
The idea behind the .tpl is to enter the variables using assign , and when the page is ready display it using display . you can set multiple variables before displaying:
<?php
$smarty = new Smarty();
$smarty->assign('firstname', 'Doug');
$smarty->assign('lastname', 'Evans');
$smarty->assign('meetingPlace', 'New York');
$smarty->display('index.tpl');
?>
If you see the text twice that means that somewhere you're calling $smarty->display('index.tpl'); once too many. To find exactly where I'll have to see your source. please post the files or the problematic bit.
Good luck anyhow :)

Don't know if this helps. but you can also return a 'rendered' tpl to your AJAX. The display-function is normaly used for the frame of the page. (sort of like the basic placeholder for everything). and is used with a page-refresh, not AJAX.
In data.php you can use
$answer = $smarty->fetch("ajaxreturn.tpl");
echo $answer;
die();
before that, you can do the needed assigns in Smarty.
In AJAX you can then place the snippet of returned HTML in the right place.

I don't understand why do you reload the whole page with ajax. If the data that changes is ie a list, can't you just create a template for that list? so...
index.tpl
<body>
... content ...
<div id="ajax_list">
{include file="data.tpl"}
</div>
... content ...
</body>
and then in data.tpl
<ul>
{foreach $rows as $row}
<li>{$row.name}</li>
{foreach}
</ul>
The first time you enter index.php it will render both index.tpl and data.tpl, and then you just have to add javascript code to refresh #ajax_list contents with data.php, that will only process data.tpl with
$smarty->display('data.tpl');
