WP FullCalendar

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

25 searches this plugin appeared in over the last 90 days, 4 listed. 21 left out as unrelated or noise (years, numbers, stray words). 4 of its tags aren't in the top 24 for their own search.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 67% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Crossed into this band 6 months ago; a band this size takes about a year or more to cross, which places it about 51% of the way through.

   The plugin works quite well. However, it was irritating that posts in the future are not displayed. This is primarily due to the query in the plugin as to whether the status is “publish”. However, WordPress sets this to “future” for the posts. However, this could be $args[‘post_status’] = array(‘publish’, ‘future’); // shows ‘publish’ and ‘future’ statussolved.

   The plugin works well but it’s not another “end user” plugin. If you are not a dev, look for another solution because it will not magically show a list of events with start date and time / end date and time functionnality, you’ll need to work on it’s available filters and some custom fields for that. Otherwise, thanks for the job, its works well except for the tax_query         $args[‘tax_query’] = array();        foreach ( get_object_taxonomies($post_type) as $taxonomy_name ) {            if ( !empty($_REQUEST[$taxonomy_name]) ) {                $args[‘tax_query’][] = array(                    ‘taxonomy’ => $taxonomy_name,                    ‘field’ => ‘id’,                    ‘terms’ => absint($_REQUEST[$taxonomy_name]),                );            }        } For some reason, if you create / edit a custom post type’s custom taxonomy, the events stop showing altogether in the calendar, even if the wpfc_post_taxonomies options field is empty. So I had to comment that whole part for it to work again. This topic was modified 2 years, 5 months ago by o2xav.

   Even though they state it will work with custom post types, it won’t display on the correct date because it relies on the post date instead. If it’s a multi day event, same thing and will only display on the post date. The plugin has potential but until the Dev makes it to where it will actually work properly with CPT’s, it’s useless.

   Easy installation, great first view. After that, this plugin is one big mistery. No documentation, explanation how it works, etc.

   I run a large series of virtual events / meetings sites on WP and I build a custom “events calendar” using CPTs and ACFs and a bunch of other things. But we needed a “calendar” view in addition to the typical “post list / loop” view. This plugin practically worked out of the box. I picked a theme to closely match our site, and added a few custom style points! I added some custom snippets to connect the start/end data to my custom fields and boom! There are some added bonuses which i appreciate as a full-time WP designer. The it’s lightweight, and even includes control of where only to load it’s scripps / styling – limiting bloat on the entire site. It also nicely sites within “Settings” where all “set it and forget it” plugins should live.

   Huge thanks to the creator of the plugin – saved me 90% of the work of integrating full calendar into a travel site. Brilliantly done – custom post types with single and multiple date metaboxes are hooked up with a couple of filter functions. Also added my own content to the pop-up tooltips and styled everything. Taxonomy filtering works great.
