[SOLVED] Nested Block Variables/Templating Question

[texasaggie]

Not really sure this is a support question but more a general "how to" type question for 3.x.

I have a template that I need to have nested values in. The documentation seems to cover this well but only from the template side.

Here's a simplified version of the template:

Code: Select all

<!-- BEGIN outer_loop --> 
  << do some markup>>
    <!-- BEGIN inner_loop --> 
      << do some markup>>
    <!-- END inner_loop --> 
  << do some markup>>
<!-- END outer_loop --> 

The question is, I'm unclear how the PHP side of this should look and I can't figure it out (have tried numerous things). What is throwing me is how to assign the template variables for the nested inner loop. Should I be assigning the vars to an array within the first array and then only assigning block variables just to the outside? I also thought you might be able to qualify/name the inner using a "outer_loop.inner_loop" convention, but that didn't do it either.

For example:

Code: Select all

<<start outer PHP looping construct>>

  $array1['a'] = 'foo';
  $array1['b'] = 'bar'l
  $template->assign_block_vars('outer_loop', $array1);

  << start inner PHP looping construct >>

    $array2 = array();
    $array2['c'] = 'oof';
    $array2['d'] = 'rab';

    // Should this be:

    $template->assign_block_vars('inner_loop', $array2);
    
    // or

   $template->assign_block_vars('outer_loop.inner_loop', $array2);
 
    // or

    $array1['innerloop'] = $array2;

   // or ????

  << end inner PHP looping construct >>

<< end outer PHP loop>>

This example might be useful:

Code: Select all

while($topic = $db->sql_fetchrow($result))
{
    $template->assign_block_vars('topic', array('TOPIC_ID' => $topic['topic_id']));

    while($post = $db->sql_fetchrow($result))
    {
        $template->assign_block_vars('topic.post', array('POST_ID' => $post['post_id']));
    }
}

Thanks! I would swear that I tried that already, but I've tried so many different variations, perhaps I did not get that one quite right. Thanks for the link as well as I had not come across that one yet.


** UPDATE: That fixed it. Thanks!

Hi..

can it be, that this function not support more than one nested blocks?

I tried the follow and get only "Parse error: syntax error, unexpected '=' in /path/includes/template.php(175) : eval()'d code on line 94"

Code: Select all

 while ($row = $db->sql_fetchrow($result))
    {
      $template->assign_block_vars('block1.block2', array(XXXX));
      if ($list_type == TYPE_AGENTS)
      {
        $agents_ary = get_agents_ary($row['a_id']);
        foreach ($agents_ary as $row_a)
        {
          $template->assign_block_vars('block1.block2.agent_row', get_agent_template_ary($row_a));
        }
      }
    }

Code: Select all

<!-- BEGIN block1 -->
  <!-- BEGIN block2 -->
    <!-- BEGIN agent_row -->
    <!-- END agent_row -->
  <!-- END block2 -->
<!-- END block1 --> 

EDIT:
sorry.. it works.. i made a mistake while i used <!-- BEGIN block1.block2.agent_row --> and not like i said it above.. now it works
