Is it possible to use nested loops in parser templates?

I am not sure if nested loops are supported by the parser, at least I am not able to display the following template correctly:

Code:

<table class="data_table">
  <thead>
    <tr>
      {header_entries}
        <th>{header_title}</th>
      {/header_entries}
    </tr>
  </thead>
  <tbody>
    {data_entries}
      <tr>
        {data_row}
          <td>{data_cell}</td>
        {/data_row}
      </tr>
    {/data_entries}
  </tbody>
</table>

The headers works but not the table's body when using these data:

Code:

   $header_entries = [['header_title' => 'one'],
                      ['header_title' => 'two']];
   $data_entries = [['data_row' => [['data_cell' => 'one - one'],
                                    ['data_cell' => 'one - two']],
                     'data_row' => [['data_cell' => 'two - one'],
                                    ['data_cell' => 'two - two']]]];
   $parser = \Config\Services::parser();
   echo $parser->setData(['header_entries' => $header_entries,
                          'data_entries' => $data_entries])->render('templates/data_table_template');

If you want nested variables to also see the level above them, then you need to pass true as a second parameter to the render() call. See https://codeigniter4.github.io/CodeIgnit...er-options

No, this is not I would like to do. I just would like to have two nested loops. But this does not seem to work because the output is:

-->header: one two
-->body: two - one two - two

The header loop is correct but the second (inner) loop is not. Only the last result of the loop is used.

The view parser supports "cascading data", but not "nested loops" the way you are looking for.
I suggest adding a feature request for this, if needed for your app... https://forum.codeigniter.com/forum-29.html
