it’s file_put_contents which saves the data then it have to be in the hook and not in the body of the plugin : function export_posts_in_json () { $args = array( ‘post_type’ => ‘post’, ‘post_status’ => ‘publish’, ‘posts_per_page’ => -1, ); $query = new WP_Query( $args ); … $data = json_encode($posts); $folder=”wp-content/themes/bootstrap/library/”; $file_name = date(‘Y-m-d’) . … Read more
You can either use the JSON API plugin, or wait for the JSON REST API project that is now running through the Google Summer of Code project. This is intended to eventually go into WordPress core, but will work as a standalone plugin for the time being.
Admin-AJAX is not optimized for JSON. If you need your answer to be in JSON, use the REST-API instead. This API generates JSON response by default. All you have to do is to register a rest route, and access the URL: add_action( ‘rest_api_init’, function () { //Path to REST route and the callback function register_rest_route( … Read more

See: http://wp-api.org/guides/extending.html#registering-your-endpoints In version 2.0 we register endpoints for any custom post types registered with the show_in_rest property set to true. Documentation on how to do this: http://v2.wp-api.org/extending/custom-content-types/#registering-a-custom-post-type-with-rest-api-support

This question is way too broad for a complete answer in a Q&A format, but here is roughly what I would do: Collect all system fonts in an array $sys_fonts Collect all Google fonts in an array $ggl_fonts Collect the complete info about Google fonts in a multidimensional array $ggl_fontinfo Merge $sys_fonts and $ggl_fonts in … Read more
If you want to use v2 of the API (which is the current one you should be using), the endpoint is mysite.me/wp-json/wp/v2/pages/1234 where 1234 is the page ID. https://developer.wordpress.org/rest-api/reference/pages/#retrieve-a-page
Found the solution: By casting the return value to an object, it is ensured that in case of an empty array, an empty object will be returned on REST request. Enhancing on my initial example, this code would work: function rest_cb() { return (object) array(); }
