Hi,

I am new with smarty and new on this forum.

I have a problem. I need to get the category id of the category table, then I have the name of the category. The category id is the 'cid' from the table 'article'.

But how can I get this in .PHP and how do I print this in the .TPL file? Do I need two foreach codes in the .TPL file?

-----------------
.php file
-----------------


Code:
$results = $db->Query("SELECT `id`,`cid`, `name`, `message` FROM `article`");


$getcat = mysql_query("SELECT * FROM `category` WHERE `id` = '".$results['cid']."'");
$getthiscat = mysql_fetch_assoc($getcat);


$smarty->assign("results", $results);
$smarty->assign("getthiscat", $getthiscat);



-----------------
.tpl file:
-----------------

Code:
{foreach from=$results item=i}


<div class='post-header'>

   <h2 class='entry-title'><a href="{$getthiscat.namecategory}/{$i.name}">{$i.name}</a></h2>

</div>                  


{/foreach}

-----------------

Thanks!

The easiest thing would be to do one query with both tables together to return both the item and category name in one go. Then you only have one db query and one result to loop over in Smarty. Also I don't your 2nd query above will work if the first query returns multiple rows.

Code:
$results = $db->Query("SELECT * FROM article,category where article.cid=category.id");


Otherwise you can use {section} to loop over and display values from multiple arrays, much like a php for().
