get_the_ID() in the footer returns wrong value

Question

I'm using get_the_ID() in footer.php but it returns a wrong value.

It might come from any of the plugin which is altering The Loop without resetting it after with wp_reset_postdata() as mentioned in $post->ID and the_id() always return the wrong value.

Indeed the page shows a list of recent posts, etc. so this might modify the current Loop.

If I can't modify this (because of third party code), how to get the ID of the current post in the footer anyway, with PHP?

What happens if you call wp_reset_postdata() in your footer before the get_the_ID()? — kero, Commented Dec 2, 2021 at 16:12
Yes it works @kero but I wanted to know if there is another less intrusive method (than resetting the postdata). — Basj, Commented Dec 2, 2021 at 16:19
Why would it be intrusive? get_the_ID() should return the correct ID. Now most likely some third party code is not behaving nicely, and with calling wp_reset_postdata() you simply reset the state to how it should have been. If something breaks, get rid of that what broke (and whatever forgot to reset the postdata). — kero, Commented Dec 2, 2021 at 16:40

In an environment without third party code, get_the_ID() should give you the correct value. It sounds like some plugin is interfering with this.

So you can do what they forgot and simply call

wp_reset_postdata()

in your footer before you need the values.
