This is exactly when *Meta Taxonomy* kicks in. **Disclaimer**: This plugin is not intended to replace the post meta API in general. There are (a lot of) cases where using a post meta makes much more sense than using a term, or where using a term is simply impossible. Installation ------------ [](#installation) 1. [Download ZIP](https://github.com/tfrommen/meta-taxonomy/archive/master.zip). 2. Upload contents to the `/wp-content/plugins` directory on your web server. 3. Activate the plugin through the *Plugins* menu in WordPress. 4. Be impressed by how fast your *meta-tax* queries can get, compared to ordinary meta queries. Usage ----- [](#usage) To be honest, this plugin is no big deal. It just provides you with a one-click solution for using high-performance taxonomy-based meta-like queries. Once the plugin is activated, you can assign terms of the new meta taxonomy to your posts, and then query the posts in a highly efficient way (compared to meta queries). ### Filters [](#filters) In order to customize certain aspects of the plugin, it provides you with several filters. For each of these, a short description as well as a code example on how to alter the default behavior is given below. Just put the according code snippet in your theme's `functions.php` file or your *customization* plugin, or to some other appropriate place. #### `meta_taxonomy_args` [](#meta_taxonomy_args) If you want to alter a specific taxonomy argument but you can't find a fitting filter, there's `meta_taxonomy_args`, which provides you with the complete args array. ``` /** * Filters the taxonomy args. * * @param array $args Taxonomy args. */ add_filter( 'meta_taxonomy_args', function( $args ) { // Turn the whole taxonomy UI invisible $args[ 'show_ui' ] = FALSE; return $args; } ); ``` #### `meta_taxonomy_capabilities` [](#meta_taxonomy_capabilities) This filter provides you with the the capabilities required for the four taxonomy-specific actions `manage_terms`, `edit_terms`, `delete_terms` and `assign_terms`. ``` /** * Filters the taxonomy capabilities. * * @param string[] $capabilities Taxonomy capabilities. */ add_filter( 'meta_taxonomy_capabilities', function( $capabilities ) { // Let meta taxonomy terms be deleted by admins only $capabilities[ 'delete_terms' ] = 'manage_options'; return $capabilities; } ); ``` #### `meta_taxonomy_description` [](#meta_taxonomy_description) If you want to alter the taxonomy description, feel free to do it via this filter. ``` /** * Filters the taxonomy description. * * @param string $description Taxonomy description. */ add_filter( 'meta_taxonomy_description', function() { // Kill the description return ''; } ); ``` #### `meta_taxonomy_labels` [](#meta_taxonomy_labels) In case you don't like the labels, easily adapt them to your liking. ``` /** * Filters the taxonomy labels. * * @param string[] $labels Taxonomy labels. */ add_filter( 'meta_taxonomy_labels', function( $labels ) { // A little more horror, please... $labels[ 'not_found' ] = 'ZOMG, no metas found!!1!!1!!oneone!!!1!eleven!1!'; return $labels; } ); ``` #### `meta_taxonomy_name` [](#meta_taxonomy_name) Yes, you can also alter the taxonomy name (slug). ``` /** * Filters the taxonomy name. * * @param string $name Taxonomy name. */ add_filter( 'meta_taxonomy_name', function() { // Rename it return 'meta_term'; } ); ``` #### `meta_taxonomy_object_type` [](#meta_taxonomy_object_type) By default, the meta taxonomy is registered for default posts (i.e., post type `post`) only. If you would like add other custom post types, do this by using this filter. You can either return a single post type slug, or an array of them. ``` /** * Filters the taxonomy object types. * * @param string[] $object_types Array of names of object types for the taxonomy. */ add_filter( 'meta_taxonomy_object_types', function( $object_types ) { // Add the taxonomy for pages and a CPT, too return array_unique( array_merge( (array) $object_types, array( 'page', 'my_cpt', ) ) ); } ); ``` ### Functions [](#functions) In order to make use of a specific functionality, there may be a function already. To prevent any incompatibility, all global plugin functions are pluggable. In the rare case where you already have a function within the global namespace with a plugin function's name, you would have to set up such a function by yourself. In principle, this is just a copy of what you can find in the `functions.php` file **of this plugin**. #### `has_meta_term` [](#has_meta_term) If you want to check wether a specific post has a specific meta term, you can do this by means of the plugin's `has_meta_term` function. ``` if ( has_meta_term( get_the_ID(), 'popular' ) ) { // Do something } ``` Contribution ------------ [](#contribution) If you have a feature request, or if you have developed the feature already, please feel free to use the Issues and/or Pull Requests section. Of course, you can also provide me with translations if you would like to use the plugin in another not yet included language.
