To get custom post types and filter them by custom taxonomies, you can do the following: or filter by more than one taxonomy (this means: give me posts from taxonomy 1 OR 3 OR 6): or to exclude posts with specific taxonomies: Maybe good to know: combining categories and tags means AND, so for example […]
There are many articles about the difference between custom taxonomies and post meta data. Here are some differences I experienced: There is no index on the post meta value. With the builtin WP_Query functionality, you cannot search with operators like <, >, =, >=, BETWEEN, etc. in custom taxonomies, so if your values are numbers, […]
You can download and install continuous Titanium builds at: http://builds.appcelerator.com/ And then install it with something like: appc ti sdk install --branch 6_3_X 6.3.1.v20171101154403 These builds are not supported, so I only do this when the official versions have a bug that needs to be resolved asap.

Custom post types are not displayed in the category and tag archives by default, even if you indicated in the register_post_type call that it should support these taxonomies. The way to include them in the category and tag archives is to use the pre_get_posts action: add_action('pre_get_posts', 'mycode_pre_get_posts'); function mycode_pre_get_posts($query) { if ((is_home() || is_category() || […]
The category taxonomy is by default a multiselect widget that uses checkboxes. There are some ways to only allow one selection, like implementing your own Walker_Category_Checklist. But the most simple solution is just replace the checkbox inputs with radio input boxes with some Javascript. In the example below, I have a taxonomy "level" that I want […]
