WP_Term_Query is a function in WordPress used to retrieve a list of terms from the database that match specific criteria. Terms are a way of grouping content in WordPress, such as categories or tags in the post taxonomy.WP_Term_Query is typically used by developers to create custom queries that display content based on taxonomy terms. For example, a developer might use WP_Term_Query to retrieve a list of posts that are tagged with a specific tag, or to display a list of categories with a certain number of posts assigned to them.WP_Term_Query allows developers to specify a variety of criteria for the terms they want to retrieve, such as the taxonomy to query, term IDs or slugs, sorting options, and the number of terms to retrieve. This gives developers a great deal of flexibility in building custom queries and displaying content in a way that meets their specific needs.
You can use the WP_Term_Query function in your WordPress code by calling it with an array of arguments that define the criteria for the terms you want to retrieve. If you want to avoid complexity, you just need to customize your requirements from our Wp Term Query Generator and use it.
