theme_hook_suggestions for string wildcard I need to create a copy of page.tpl.php using page--fixed_arg_0__variable_string_arg_1__fixed_arg_2.tpl.php as pattern. For example, if the URL is http://example.com/models/model-title/special-offers, model-title is the variable. I only want one template file instead of 10 or more.

Any suggestions?
What you'd need to do use the theme suggestions. So you'd have 1 template file e.g. page--fixed.tpl.php

Then in template.php you could have an if statement e.g.:

function THEME_preprocess_page(&amp;$variables) {
 $arg1 = arg(1);
 $arg0 = arg(0);
 if($arg0 == 'models' &amp;&amp; ($arg1 = 'model-names' || $arg1 = 'anothermodel')){
  $variables['theme_hook_suggestions'][] = 'page__fixed';
 }
}
