php - Wordpress - is_page_template -

I am using the following code to set the column width on some pages within a WordPress site:

  if (is_page_template ('fullwidthhome.php')) {global $ content_width; $ Content_width = 1080; / * Pixel * /} otherwise (is_page_template ('wideContent.php')) {global $ content_width; $ Content_width = 1080; / * Pixel * /}  

This works great on pages with custom templates, but I'm not sure how it should work for custom post types.

This does not look like when I set up my custom post type template:

  elseif (is_page_template ('single-widecontent.php')) {global $ Content_width; $ Content_width = 1080; Class = "post-text" itemprop = "text"> 
 About this function  get_post_type ()
