After further research I figured out a solution. Given the following WP_Query: <?php new WP_Query( array( ‘s’ => ‘some keyword’, //keyword criterion ‘category’ => ‘some category’, //taxonomy criterion ‘_spec’ => ‘some value’, //custom criterion to be handled by the plugin ) ); ?> You can handle custom parameters using pre_get_posts in combination with posts_where: <?php … Read more
In custom tables you do whatever you want. If a view is what you need, use it. However, you might consider separating the code in an exporter. See wp-admin/includes/export.php for a start. If you keep the actual SQL and the export format separate you can: create a new exporter for another table structure easily use … Read more
You actually have several questions in there, so I’ll answer them one by one: However, if I simply do this on my main plugin file, it doesn’t work: add_filter(‘pre_set_site_transient_update_plugins’, array(‘XYZ’, ‘check_update’)); First of all, I’d like to understand what’s the difference between the two scenarios. This is failing because you are calling the method statically, … Read more
This is not possible the way you think. It would maybe be possible if you use Reflections or debug_backtrace(), but there’s no reliable way to do this. WordPress does not keep a stack or queue where it tracks file names. The only thing I could imagine is just hooking into the action and inside wp_enqueue_scripts(): … Read more
You can use wp_enqueue_media() in your admin_enqueue_scripts hook. In a javascript file hook it into a button and use insert event to capture the selected image’s details $(‘.media-button’).click(function() { var media_uploader = wp.media({ frame: “post”, text : “Add image”, state: “insert”, multiple: false }); media_uploader.on(“insert”, function(){ var json = media_uploader.state().get(“selection”).first().toJSON(); var image_name = json.filename; var … Read more
You should store a version number for your plugin in the database (if you don’t already, add this pronto), using that you can do this (note that this is pseudocode): if( $db_version < {your desired version} ) { // previous updates and such $db_version = $new_version; //put that in the database } if( $db_version < … Read more
There’s a reason why add_role() has the $capabilities as 3rd parameter. First some insights on what happens, when you use the function. It calls WP_Roles->add_role() – the class method The method then does a check if the role already exists. If yes, it aborts. The next step is, that it adds the role to WP_Roles->roles[] … Read more
The query vars filter is unnecessary for what you’re doing here, as you’re not using it in a query. Adding it to the URL as a GET parameter will not make it appear in the array of query vars, as there’s no mechanism that converts a GET var to a query var, you’ve only ensured … Read more
I was having this same issue and was able to correct it by expanding on Andy’s solution, however I only needed to force on value in particular to not use W3TC’s object cache. I tried using APC, Memcached as well as Disk for the cache with the same results. Caching certainly helps performance, and the … Read more
