serialize representation can be stored in text and reversed JSON representation can be stored in text but cannot always be precisely reversed Run this example: $query = new WP_Query(); var_dump( $query ); var_dump( unserialize( serialize( $query ) ) ); var_dump( json_decode( json_encode( $query ) ) ); After going through serialize accurate WP_Query ...

It did appear that the json wasn't being cached by wp-super-cache, but we decided to take a different approach. By using the transient api, we were able to do a faux-cache on all json, and drastically reduce the taxing of the database. Then on the ajax side of things, we are caching the html that is created from this semi-cached json. Things are super ...

I don't think using React.js without Node.js (or at least V8 or rhino etc) counts as isomorphic, as isomorphic means that you are building JavaScript to run in the browser AND on the server. Specifically, using WordPress certainly means you aren't doing isomorphic javascript (its PHP software). What you could do is use WordPress as a REST API server, and ...

If you are using PHP 5.2+ you're best bet is to just make a PHP array or object and use json_encode(). UPDATED: $cats = get_categories(); $output = array('categories' => array()); foreach ($cats as $cat) { $cat_output = array( 'cat_id' => $cat->term_id, 'cat_name' => $cat->name, 'posts' => array(), ); ...

TL;DR Yes, WordPress can certainly act as a backend for a mobile app. Yes, a page can act as a rest endpoint / interface. No, a theme template is not the right territory for the logic. Write your own plugin. Pointers I find it hard to believe that no one else has done this. I, for one, have. More than once. And I'm near certain I'm not alone. "No ...

My idea was to schedule this function, so it will run once every day or so. After some more research I should be able to fix this (using this post). Note that WP_Cron setted to daily is impossible to control exactly at what time the creation happen. If no one visit your site on night the first user on morning will experience a very long page loading ...

I took a look at the WordPress app for Windows 8. It looks as though it is strictly built for WordPress.com, not self-hosted blogs. The apps available for Android, iOS, and Windows Phone on the other hand actually support both self-hosted installations and WordPress.com. Even though you integrated some WordPress.com services into your blog via JetPack, it ...

WP Super Cache examines your WordPress site's pages for some HTML tags before it caches them. Your pages most probably don't have </html> tag (common issue), in that case, try adding something like //</html> -- that's a workaround, and WP Super Cache should then generate cached versions of your pages. Why does WP Super Cache do it like that? ...

Here is some quick first draft code for populating a dropdown from the Google Font API, I do not know about the options framework so this will not deal with that. 1. Get an API Access Key from Google Your request will need a valid key, you can follow the instruction here on how to get one: https://developers.google.com/webfonts/docs/developer_api It's ...

This is the approach to add a rewrite rule for swapping out the template that WP wants to render (usually the 404 template) with something else. In your case you're just wanting to die with some JSON data so there are a bunch of different ways to do this. This is the "by the book" approach to adding a rewrite rule instead of a hack to check the URL on your ...

Depending on what kind of HTML you're expecting, there are different tools you can use: esc_html() escapes entire HTML blocks so you don't end up with breaking characters in your JSON object literals. esc_html_e() escapes (as above) and translates the string if you're concerned about localization in that context. wp_kses() will parse the HTML string and ...

Ok, found. I spent hours on this but I managed to find the solution. The command I was looking for was $rss->enable_order_by_date(false);. So you should set (for benefit of the community): <?php /* include the required file */ include_once(ABSPATH . WPINC . '/feed.php'); /* specify the source feed */ $rss = fetch_feed('FEED_URL'); ...

wp_send_json() handles all parts of returning content in an AJAX call. First off, it sets the content type of the returned content to application/json with the proper charset. Secondly, it automatically calls wp_die() after sending the JSON result, which is necessary in an AJAX call in WordPress. You could consider using wp_send_json_success() for ...

Sorry for answering my own question but it may help some other devs too. I created this additional filter 'json_query_var-meta_query'that returns the necessary arguments. function adjustQrry($data){ $args = array(); $args['relation'] = 'AND'; foreach ($data as $key=>$value) { if ( 'relation' === $key ) { ...

There are two parts to the solution here. You need to use a JSON API custom controller In your custom controller, you'll need to decide how to pass the meta_query data structure Depending on how robust you need this to be, you could use a variety of approaches. Here is the maximalist approach, that will allow any kind of meta_query, encoding the ...

For the record, I'm not sure why anyone would use the JetPack JSON API as it currently works for a self hosted site. If you're doing AJAX and JSON, the whole point is to get back some JSON data FAST. Using jetpack involves an unnecessary call to wordpress.com, which then does a call to your own self hosted blog. Using the wonderful JSON API plugin, you ...

There is an elegant way to handle this! Pass the JSON encoded string through wp_slash(). That function will escape the leading slash of each encoded unicode character, which will prevent update_metadata() from stripping them.

it seems the latter only accepts x-www-form-urlencoded That's not completely true. WordPress admin-ajax.php takes the action from $_REQUEST['action'] and $_REQUEST is equal to: array_merge($_POST, $_GET); But what many people don't realize is that $_GET in PHP is not the data was sent to page using HTTP GET method, in fact, you can use whatever ...

The easiest way I can think of (and the only one) is create a page with the permalink you're indicating, create a custom template in your theme folder, let's say it's json_output.php with the following content: <?php /* * Template Name: JSON Output */ header('Content-Type: application/json'); $cats = array('Hobbes', 'Simba', 'Grumpy Cat'); echo ...

I will give you a small answer to your update, doing this with the WP API. The API have the possibilities to use the WP_Query like also in core, but about the get parameters in the url. A URL to pull content from Post Status would look like this: http://example.com/wp-json/posts To pull content with WP_Query parameters you’re used to, you could do it ...

The problem will likely be a (very slow) callback that is attached to your get_the_excerpt() function. To inspect the attached callbacks, just inspect the global: // Best hooked to `shutdown` echo '<pre>'.var_export( $GLOBALS['wp_filters']['get_the_excerpt'], true ).'</pre>'; Then get rid of all those callbacks.

json_decode the JSON into an array. $slices = json_decode(file_get_contents('yourJSONFile.json'),true); Loop into the data if ($slices) { foreach ($slices as $slice) { $title = $slice[1]; // insert more logic here } } Create a post programmatically by using wp_insert_post. // Create post object $my_post = array( 'post_title' ...

I have used symbolic links for convenience for awhile on a dev server but they are not 100% reliable as some PHP functions will return the filesystem path of the target instead of the path to the symlink itself. The most notable example (though not really a function) is the magic constant __FILE__. (Also https://bugs.php.net/bug.php?id=46260) That can cause ...

You can add your own AJAX API for do_shortcode. Add this to a suitable location (i.e. functions.php or a plugin): add_action('wp_ajax_doshortcode', 'ajax_doshortcode'); function doshortcode() { echo do_shortcode($_POST['text']); die(); // this is required to return a proper result } And this to your Javascript: $.ajax({ url : ajaxurl, data : { ...

The AJAX request would query for the dates it requires to display. With Lazy fetching set, if you switch from month to week or day views it won't bother making another request, since it doesn't need to. This is outlined in the fullcalendar documentation. As for using this method, see this question on how to obtain the admin-ajax.php url properly. Next, you ...

Doesn't look like there's any way to avoid it. The update_metadata() function, which is ultimately responsible for saving the meta, explicitly runs a stripslashes_deep() on the meta value. This function will even strip slashes from array elements, if the value were an array. Theres a filter that's run AFTER that called sanitize_meta, which you could hook ...

I think we're not far away from being able to achieve this in a pretty sensible way. The WordPress.com website has already moved over to a JavaScript application powered by a REST API with Node.js and React. Moving the core WordPress software over to newer technologies like this will take time, but if you add plugins such as WordPress REST API you should ...

If you want the D.I.Y. route... The post type in this example is set to 'post' but you can see where to change it. Here is a working example to pull the data ( first page in this example ), parse the response, create a class for the clean(er) data, generate posts from that data then update the post meta for specific attributes. You'll want to adjust what ...

I've been building an app in Rails that uses react JS heavily. It's a good project to work on because it's giving me the baseline understanding on how React works. Knowing what I know about React, I'd highly recommend not using it with WP until you get a grasp on it initially, I think it'll make your learning process much longer trying to hack it into WP. ...

I found the answer, dropping it here in case someone need it. You need to be logged in as a user that has the edit_posts capability. With that capability, you also get access to the private query vars, including post_status. Taken from this similar issue.
