in post you use <!--more--> for a page you use <!--nextpage-->
Thanks, but…
<!–more–> defines the pre-‘read more’ break-point in places where the whole post isn’t shown.
<!–nextpage–> will split a post into multiple pages.
@gulliver: The <!--nextpage--> quicktag works for Pages, too; but the wp_link_pages function also has to called by the Template File your theme is using to display the Page in question in order for the links to actually be visible.
@girlieworks… Thanks.
@staartmees… Also, thanks – and, more importantly, I apologize for doubting you.
Somewhere between ‘old age, stupidity, dust on screen and glasses’ I’d incorrectly pasted a quicktag with just a single (rather than double) dash. Hence it didn’t work.
And being totally honest, I’d forgotten that <!–nextpage–> worked on pages and thought it just for posts. Clearly I must have once known it, because my custom theme has the necessary code, appropriately tweaked, and which I must have added years ago.
Duh me!
Anyway, thanks to you both for saving me from myself. 😉
