[Parser] Nested Substitutions not working

[Alex-Licea]

Hi everybody:

When I try to run a nested substitution with view parser like the example in the docs view_parser.html#nested-substitutions, CI return an exception:

ErrorException Invalid argument supplied for foreach() SYSTEMPATH/View/Parser.php at line 314

I've used CI version 4.2 and 4.3 and the issue is the same.

The only way to make it works is to change the example $data array from the docs example:

$data = [
    'blog_title'   => 'My Blog Title',
    'blog_heading' => 'My Blog Heading',
    'blog_entry'   => [
        'title' => 'Title 1',
        'body'  => 'Body 1',
    ],
];

To this:

$data = [
      'blog_title'   => 'My Blog Title',
      'blog_heading' => 'My Blog Heading',
      'blog_entry'   => [
            [
                  'title' => 'Title 1',
                  'body'  => 'Title 1',
            ],
    ];

The parser can't handle a single level of values in the array, they need to be contained in array to make it work. This behavior is the right one or the docs are outdated?

Thanks for your support.

This is the repository for CodeIgniter3.

But you are correct. The sample code is not correct.
See codeigniter4/CodeIgniter4#7103
