WordPress apply get_excerpt formatting to a string

0 Views

I would like to apply wordpress’ get_excerpt format to a string I pass to it.

I know the standard excerpt only works within the loop – but I’m hoping there is a function or something I’m missing that generates the excerpt when you don’t manually define one.

    You need wp_trim_words(). Yes – you’re right. wp_trim_excerpt() doesn’t play nice with passed strings.

    WordPress uses wp_trim_excerpt() to generate excerpts.

    You probably want some filtering on there too before you output (depending on the source of your text).
