  • WordPress: Publishing posts in the past

    in

  • WordPress: Get IDs of *ALL* post tags

    in

    WordPress contains a function for getting the tags associated with a post (get_the_tags) but none for retrieving the IDs of all site wide available tags.

  • The selectbox mystery of WordPress

    in

    The other day I wanted to use a selectbox with 5 elements in my plugin’s option page.

  • WordPress plugins: Don’t hard code path names …almost never!

    in

    The other day I found a plugin claiming the following in its instructions: 1) Upload the entire my-cool-plugin folder to the /wp-content/plugins/ directory 2) DO NOT change the name of the my-cool-plugin folder […] What the heck?
