hello everybody,
i want to make a very simple plugin that will check every post for a certain tag (for example: [id 1234ABCD] )
if a post is detected with the [id xxxxx] tag, i want it to then generate the post content from another table.
i've seen many plugins use this model, even the wordpress photo gallery is a similar syntax. but as the title says, I have no idea what terms to search for to start my learning quest.
also, this doesn't have to be a whole separate plugin, i would be fine with just cutting and pasting the code where it is needed.
thanks for the read!
