I have a custom post type called Projects. It contains a text-area "project description" and a repeater image field. I know that I can use the function WP_Query to return an array containing all my Projects post. This works when I want to show all the projects in one page. My question is how do I handle single entries in the Projects post type. More specifically, I want to know about the function that returns reference to a single entry of Project post type and the template file to be edited so as to achieve the styling of that single custom post page.

    You probably want to create a single-{post_type}.php template in your theme folder. {post_type} is the string you have passed to register_post_type() as the first argument. Start trying to copy you theme's single.php file. More on the template hierarchy here. – Luis Sanz May 21 '16 at 10:03
  • Thanks. That answers the second part of the question very well. Can you tell me what function to use to get a reference to the particular entry that I will be styling through the mentioned single-{post_type}.php . I have coded the page that displays all the projects excerpt. Now I want the user to be able to have a full display of all the contents of a single project that he clicks on. – Abhilash Singh May 21 '16 at 10:10

    You don't need to call any specific function. When you visit a single custom post type entry, the content is parsed through The Loop. You don't need to create a new query, the query is already created by WordPress. What you need to do is just run your while ( have_posts() ) boucle and style the content within. For example, have a look at how it's done in the [_tk theme(github.com/Themekraft/_tk/blob/master/single.php). – Luis Sanz May 21 '16 at 10:26

As per comments the single view of your CPT will be handled according to template hierarchy. Within appropriate template you can use template tags normally, so simply get_post() without arguments will get you a current instance.

It is a little more tricky if you want to refer to a specific post in code outside of its context.

The most reliable within custom site is hardcoding its ID. Personally I also use get_page_by_title() (despite name can work on arbitrary post type) which is easier for human to read, but depends on title staying unchanged.
