custom node template (content type) is not working on drupal 7

Question

After applying following code into template.php, custom node template is not working on Drupal 7. For example, node--article.tpl.php

function jstheme_preprocess_page(&$variables) {
  if (isset($variables['node']->type)) {
// If the content type's machine name is "my_machine_name" the file
// name will be "page--my-machine-name.tpl.php".
$variables['theme_hook_suggestions'][] = 'page__' .    $variables['node']->type;
  } 
}       

If I remove above code, node--article.tpl.php is picking up but not page--article.tpl.php

I assume that it should pick up page--article.tpl.php then node--article.tpl.php if they exist. Is this assumption wrong?

Answer 1

The above code and your assumption is right. I tried using the above code in my local it worked fine, as a result it took page--article.tpl.php as page tpl and for node tpl it took node--article.tpl.php .

Steps to check:

1. hook_preprocess_page written in template.php will always take the priority.
