Mustache template with label

Question

If I have the following array

array (
    'people' => array(
        [0] => array('name'=>'name1'),
        [1] => array('name'=>'name2', 'last' => true)
    )
);

and I want to output it using a Mustache template so that the final html looks like this:

<div>
    Names: name1, name2
</div>

Though if the array is empty then it shouldn't output anything.

This is my current template

<div>
    {{#people}}
        Names: {{name}}{{^last}}, {{/last}}
    {{/people}}
</div>

which outputs

<div>
    Names: name1, Names: name2
</div>

I understand why it doesn't output what I want but I don't know how to solve it.

<div>
    {{#people.0}}
        Names:
        {{#people}}
            {{name}}{{^last}}, {{/last}}
        {{/people}}
    {{/people.0}}
</div>

The reason you were getting Names: written twice was because everything inside {{#people}} and {{\people}} is treated as a loop.

Yes becuase then if there are no people, the `Names:` label will still be there. – Oskar Persson May 27 '14 at 15:29
Add a `hasNames` key to your array, or use the hacky `{{# people.0 }}` to check whether it's empty: http://stackoverflow.com/questions/19572096/mustache-how-can-i-do-something-once-for-an-iterable/19577717#19577717 – bobthecow May 28 '14 at 15:02
Or you can use `{{#people.length}}` (updated the answer) – Jon Sturdevant May 28 '14 at 20:03
Sorry - it's php `.length` probably won't work. I'll refer you back to the comment that @bobthecow made. – Jon Sturdevant May 28 '14 at 20:07
No I can't get `.length` to work but `#people.0` works great, thanks – Oskar Persson Jun 24 '14 at 20:16
