Question

In this http://codeigniter.com/user_guide/libraries/parser.html tutorial we have this multidemensional array

$data = array(
          'blog_title'   => 'My Blog Title',
          'blog_heading' => 'My Blog Heading',
          'blog_entries' => array(
                                  array('title' => 'Title 1', 'body' => 'Body 1'),
                                  array('title' => 'Title 2', 'body' => 'Body 2'),
                                  array('title' => 'Title 3', 'body' => 'Body 3'),
                                  array('title' => 'Title 4', 'body' => 'Body 4'),
                                  array('title' => 'Title 5', 'body' => 'Body 5')
                                  )
        );

And we printing him easily like this

{blog_entries}
    <h5>{title}</h5>
    <p>{body}</p>
{/blog_entries}

But how to output array like this one https://i.stack.imgur.com/WniLT.png 😕

 $data = array( 
array(
    'user' => array('id' => "1", 'name' => "Test1"
    ),'title' => 'Title 1', 'body' => 'Body 1'),
array(
    'user' => array('id' => "2", 'name' => "Test2"
    ),'title' => 'Title 2', 'body' => 'Body 2'),
array(
    'user' => array('id' => "3", 'name' => "Test3"
    ),'title' => 'Title 3', 'body' => 'Body 3')
);

If we trying to do something like this

{blog_entries}
    {user}
        {id}
    {/user}
    {title}
    {body}
    <br />
{/blog_entries}

We ll have error:

Message: Invalid argument supplied for foreach()

Ah, found similar problem here Extended Template Parser: CodeIgniter… Issue with Nested Arrays

Setup your array more like this

$data = array( 'user' => array('id' => "1", 'name' => "Test1", 'title' => 'Title 1', 'body' => 'Body 1'),
                         array('id' => "2", 'name' => "Test2", 'title' => 'Title 2', 'body' => 'Body 2'),
                         array('id' => "3", 'name' => "Test3", 'title' => 'Title 3', 'body' => 'Body 3')
);

And after that, it’s kind of like nesting HTML tags, except with key->value pairs in a PHP (If that make sense).

{user}
    <h4>{name} : {id}</h4>
    <span>{title}</span>
    <p>
        {body}
    </p>
{/user}
