Sometimes it is undesirable to allow access to a template via a URL. For instance, a template that you only use as an embedded template would likely be an incomplete HTML document, and you wouldn’t want visitors to be able to view that template by itself on the front-end of your site.
“Hidden” templates are just that: templates that cannot be accessed from
a URL, but can be used as embedded templates. To make a template
“hidden”, simply give it a name preceded by an underscore, e.g.
When a Hidden Template is Requested as a URL¶
When someone attempts to access a hidden template via a URL, one of two things will occur. If you have specified a 404 template in your Template Settings, then the 404 template will be displayed, with 404 headers. If you have not specified a 404 template, then the index template of the requested template group will be displayed.
Changing the Hidden Template Indicator¶
By default, a template is hidden when an underscore prefixes the
template name, but this can be changed with a configuration variable set
$config['hidden_template_indicator'] = '.';
