Hi,

i'm new in Smarty template and perhaps it's not a bug...
I have a Url class with a fromLinks array, i populate this array like this:

Code:
function addFromLink($id,$url)
{
   $this->fromLinks[$id] = $url;
}

with these datas (ex 5 rows) { 4=>"http://...",5=>"http://..."}


where the $id is an int coming from an sql database and the url is an url...

when i do this in php for debug:
Code:
foreach($url->fromLinks as $key => $value)
{
   echo "array: ".$key.":".$value."<br>";
}


it works well i have 5 rows but when pass $url->fromLinks as fromLins to Smarty template with this code:
Code:
{section name=link loop=$fromLinks}
<tr><td>{$link}:{$fromLinks[link]}</td></tr>
{/section}


the result is 4 + 5 rows , how can i do to avoid smarty not to loop on the 'empty' rows ? Smaty seems to loop on 0,1,2,3,4 keys but they does not exist...

Thanks for your help,

Julien

Hi,

The smarty section begin at id 0 of the table and loop x times (number of items in the table). So for your example, for 5 lines starting at id 4, it'll will go throw 0,1,2,3,4 and you'll not see the end ...

You say that your datas come from an SQL Database.
Perhaps it's simplier to do like this :

PHP :
Code:
$SqlQuery="select Id, Url from ...";
$fromLinks = $db->getall($SqlQuery,DB_FETCHMODE_ASSOC);
$smarty->assign('fromLinks ', $fromLinks );


Template :
Code:
{section name=link loop=$fromLinks}
<tr><td>{$fromLinks[link].Id} : {$fromLinks[link].Url}</td></tr>
{/section}





Hope this will help you

Using {foreach} instead of {section} should help too.
