How to Get Specific Custom Field Values in WordPress

If you want to make your post display more detailed and comprehensive, or you want to exhibit it according to your requirement, then you need to have some latest updates in your WordPress.

To do this task, you have to add some lines of code or there is another option which is provided by WordPress itself in which you can get WordPress (free and open source blogging tool and a dynamic content management system) that helps you in assigning custom field values in posts. This extra information which you added is called meta-data.

This meta-data is controlled with key/value pairs. The Key is basically the name of meta-data element which can be used in more than one per post while the Value is the information which will appear in the meta-data list on each individual post.
