Mustache templates: How to output a block only once for non-empty lists

阅读更多关于 Mustache templates: How to output a block only once for non-empty lists

问题 If my list is empty, I want to output this: <div id="some-id"> </div> If my list is non-empty, I want to output this: <div id="some-id"> <ul> <li>Item 1</li> <li>Item 2</li> <li>etc</li> </ul> </div> Note that I output the <ul> and </ul> tags at most once , and only if the list is non-empty. The following code is close to how I would do this in PHP, but is obviously wrong: <div id="some-id"> {{#items}} <ul> {{/items}} {{#items}} <li>{{name}}</li> {{/items}} {{#items}} </ul> {{/items}} </div>

PHP Mustache 2.1 partial loading NOT based on the filename

阅读更多关于 PHP Mustache 2.1 partial loading NOT based on the filename

问题 Is there a way to load partials based on an array of filename values? Currently if I write this {{> sidebar}} it will look for views/sidebar.mustache . (based on the template loader class where I can specify where to look for the templates) Ideally I want that {{> sidebar}} would be a variable name and not a file name. What I want to achieve is to look for the sidebar partial not based on the filename, if I pass to the loader: $partials = array( 'sidebar' => 'folder1/somefile' ); which would
