You could definitely use an MVC philosophy in the development of a plugin, but you would be really silly to try to incorporate CI or Cake in addition to WP. For instance, you could build out a plugin using the following pseudo structure (FYI, there are a ton of ways to build this, depending on … Read more
You should not access the database directly, if at all possible. There are two main reasons for this: If the database structure changes (unlikely), your queries may become outdated. Using functions like delete_user_meta() will ensure that your query should work properly for all WordPress versions (past, present, and future) that support that function. Caching. If … Read more
There are two things that confuse people when trying to remove a hook: The remove_action() or remove_filter() calls must take place after the add_action() or add_filter() calls, and before the hook is actually fired. This means that you must know the hook when the calls were added and when the hook is fired. The remove_action() … Read more
This will handle appending the content to single posts: function yourprefix_add_to_content( $content ) { if( is_single() ) { $content .= ‘Your new content here’; } return $content; } add_filter( ‘the_content’, ‘yourprefix_add_to_content’ );
Outside of using other plugins, as mentioned in the comments, you would need to essentially parse the LaTeX yourself by filtering the_content. Here is a very rough example of how you might capture and transform the post content to parse a bibliography. Please note that I don’t know LaTeX, and this is just string parsing. … Read more
With Multisite, you need to use add_site_option/get_site_option instead of add_option/get_option. https://codex.wordpress.org/Function_Reference/get_site_option
This is a partial answer, because as I mentioned in my comment I’m not sure why your code is requiring two ‘really bad words’ at the moment. It’s also an untested attempt. I’ll deal with your first question: how to send a user back to the posts page and display a suitable error message, rather … Read more
I would probably either use GravityForms or CForms plugins to allow that, both have a “form to post” feature that creates a new post and lets the admin moderate it before publishing.
At this time, this is not possible. Not without the PHP minimum version header being implemented. When that is done, then it will be possible. Until then, you cannot DIY through plugin code alone. In theory, you could release an update that would block future updates for that one plugin if the PHP version wasn’t … Read more
@pwnguin, I had the same problems running mod_php with WordPress and I finally figured it out. # chown www-data:www-data /home/CIM140/public_html/wordpress/ -R As long as YOU control the box this won’t cause any security issues. EDIT: You might also need to change your umask to 022 so new directories created by WordPress will have 755 permissions … Read more
