I need to get the current PostID. I think in the function the postID is not existing yet. (Because save pre ...)

add_filter('content_save_pre', 'getImageUrlOutOfContent', 10, 1);

Am I right? How I can get the postID? Is there a better hook? I am updating the content (text) and uploading and adding a postImage.

Thank you

  • If it's a new post and you are looking to update the content before it's saved then it will not have a $post->ID yet. You'd need to allow the new post to be inserted into the DB, then get the resulting ID.

There's no hook for "give me a post ID before the post has been created". You only get an ID after the post has been saved. So yes, use the hook 'content_save_pre' to modify your content before saving, then once you get back a post ID use that ID to update the post featured image.

There's a great answer describing how to acquire and set the image for a post, here

And, the hook you'd use to trigger that set image routine would be 'save_post' which is documented here
