I have been spending some time working with the new Rest API. I understand what it is doing but I don't understand how the JSON is used to actually display the content on a page.

I have been fooling around with example.com/wp-json/posts and I see all the code. I can even figure out how to filter them the way I want. What I can't seem to figure out is how do i display this content in a WP post or page?

example: I am using a multisite install and I would like to use 5 of the most recent posts from SITE A on SITE B but I don't understand how all that JSON code is edited and displayed.

I can't seem to find any beginning to end samples on this subject everyone just shows how you grab the content.

I will assume you want to use PHP to display this data directly using a template, there are alternatives such as using another language or actually creating posts via the API.

Simply put you want to take the JSON string and convert it into a PHP object or array using json_decode. http://php.net/manual/en/function.json-decode.php.

Once the JSON is stored as an object or array you would simply echo or do what you want with the data.

For example:

$json = '{"a":hello,"b":hi,"c":hey,"d":yo,"e":ola}'; $data = json_decode($json); echo $data->{'a'} // this should echo the value "hello"

It's important to note to cache external requests, you do not want to make a remote request each time the data is needed, rather you would use the Transient API with a set time for the data to expire and refresh.

  • Hi Wyck thanks. I am not using this live I am just trying to learn it.So doing this with RSS is still a better way? Commented Dec 7, 2014 at 21:37
  • Better is subjective, it depends on your needs, in my opinion a REST API is certainly superior to an RSS feed, they are not really comparable, but this wasn't your original question. Commented Dec 7, 2014 at 21:49
  • Np I actually phrased that wrong. I am going to edit my original question now that I have learned a few things based on your reply Commented Dec 7, 2014 at 21:53
