Is it possible to display a warning in the admin section when posting if the excerpt section hasn’t been filled out to stop a post being published without an excerpt?
Does anyone know of a plugin that has this facility?
Show validation warning if no Excerpt is added
Writing your own plugin will help you understand WordPress better, subsequently enjoying it even more, beside you look like you are quite capable with some tiny bit of PHP, no?
When saving a post, the
save_posthook is pulled on. This passes along the$post_IDand the$postvariables, containing everything you need to check forpost_excerpt(likeif ( strlen( $post->post_excerpt ) < 10 ) ...).If you want to explicitly do this only when a post is published you can hook to
{$old_status}_to_{$new_status}hook.To show a nice message or warning, tap into the
post_updated_messageshook. You can alter the$_GET['message']variable inside theredirect_post_locationfilter.Alternatively, you can display the warning on the page at all times just by looking at the
$post->post_excerptproperty. Style it as an alert or use jQuery to remove the publish button altogether until the field is filled. Lots of options, depends on how far you’re willing to take it.
