Drupal 7 Template Suggestions -- Why is this not working?

I've created my own theme. In the template.php file, I have the following code:

function mytheme_preprocess_page(&$variables) {
    if(isset($variables['node'])){
        if($variables['node']->type === 'sports'){
            $variables['theme_hook_suggestions'][] = 'page__node__sports';
        }
    }
}

And I have a page_node_sports.tpl.php file in my theme's template directory, and I have cleared the cache. However, the page_node_sports.tpl.php template doesn't get used. Doing some debugging, I stuck an echo statement at the beginning of the preprocess_page function, and that did appear onscreen, so I know the function is running. But the template suggestion just isn't working. I even removed the if statements insid开发者_C百科e the function, leaving just the $variables['theme_hook_suggestions'] = ... line, but still nada.

Any idea what's going wrong?

Have you also added a page.tpl.php to your theme folder? Suggestions only work if the original template exists too.

Figured it out. Although the template name in the line:

$variables['theme_hook_suggestions'][] = 'page__node__sports';

should have underscores, the actual .tpl.php file should have hyphens instead.
