Pointers for new plugin writer
I have an idea for a plugin, and I’m trying to write it myself — A plugin to auto-approve trackbacks from certain blogs. There would be a configuration screen added to the admin menu where you would add in domain names from blogs that usually link to you in their posts. When a trackback comes in, WP would use the plugin to check if the domain name matches one on the list; if so, it would be automatically approved.
But I’m still learning how WordPress (and PHP) works, so naturally I’m stuck. Can anyone provide any pointers (web links, tutorials, sample code/plugins, etc) on any of the following:
- How can my plugin tell when a new trackback has been received?
- How can I programmatically approve trackbacks?
I’ve checked out actions like pre_ping and pingback_post, but none of them include the pingback URL as an argument. I know that you can configure WP to moderate first-time commenters, and thereafter comments from the same person are automatically approved. Would it be worth it to study that code? If so, where do I find it?
Thanks for your time,
