Try out the below code:

For the variable, you don't need to use '' for that.

$metadescription = wp_trim_words( get_the_content(), 55, '');

add_post_meta($post_id, 'meta_description', $metadescription , true);

CodePudding user response：

First, make sure that get_the_content is returning the content you want and $meta_description isn't null.

Try This:

add_post_meta($post_id, 'meta_description', '' . $meta_description . '', true);

CodePudding user response：

You're enclosing the variable $metadescription in single quotes.Single quotes prevent variables from being evaluated and instead treat the enclosed string literally Try this :

$metadescription = wp_trim_words( get_the_content(), 55, '');

add_post_meta($post_id, 'meta_description', "$metadescription", true);
