Question

We have a social network startup and we need to integrate smarty templates. I have a php array namely $profile_tasks . An element in $profile_tasks have the following properties ;

    [0] => Array
    (
        [name] => hello
        [location] => 
        [date] => 
        [time3] => 0
        [time1] => 
        [state] => 0
        [like_count] => 0
        [comment_count] => 2
        [does_id] => 91
        [comments] => Array
            (
                [sender_id] => 27
                [content] => khhkhjkkhk
                [time] => 2012-02-09 20:06:13
                [user_name] => aacanakin
                [picture_url] => http://graph.facebook.com/fb_user_name/picture
            )

    )

In my smarty template file, I have assigned the $profile_tasks array like this ;

$smarty->assign("profile_tasks", $profile_tasks);

In my .tpl file, there is no problem in printing any of the attributes like [name] or [location] fields. I have the following code for name printing ;

  {foreach name=outer item=profile_task from=$profile_tasks}  

    {$profile_task.name}
    {$profile_task.locatin} // these two works correctly

    {foreach name=inner item=comment from=$profile_task.comments}

      {comment.user_name} // these three statements doesn't return correct values
      {comment.picture_url}
      {comment.content}

    {/foreach}  

   {/foreach} 

So, as I stated before, the values inside comments array are not correct. What should I change in the inner loop ? Any help will be appreciated.

Answer 1

Just use

  {comments.user_name} // these three statements doesn't return correct values
  {comments.picture_url}
  {comments.content}

you dont need

  {foreach name=inner item=comment from=$profile_task.comments}

if your comments array had multiple sub arrays then you would.

UPDATE:
Update based on comment. Your array needs to look like this for your origional code to work

    [comments] => Array(
    [0] =>  Array
        (
            [sender_id] => 27
            [content] => khhkhjkkhk
            [time] => 2012-02-09 20:06:13
            [user_name] => aacanakin
            [picture_url] => http://graph.facebook.com/fb_user_name/picture
        )
   )

PS. On a subnote, I very early on realised that using the default {} to denote smarty tags is really annoying as you cannot happily co-exist with javascript on a html template page. If you havn’t gone too far down the route I would use

$left_delimiter -> '{[';
$right_delimiter -> ']}';

to specify an alternative. This means you dont have to worry about using the {literal} tags anywhere.
