I want to be able to remove automatic excerpts (and keep the custom ones) only on single posts since I make use of automatic excerpts in my archives. I am using this code:

if ( is_single() && 'post' == get_post_type() ) {

But it doesn't seem to be doing anything. Without the condition, it strips out automatic excerpts from all places where excerpts exist.

  • Test each half of the condition independently to see which conditional is failing.

  • did you try if (is_singular('post') ) { }?

  • @rudtek Yeah, same issue, it displays automatic excerpts on single posts. Commented Oct 19, 2022 at 10:49

It seems to me that your code runs too early, i.e. before WordPress determined what the queried object is, i.e. whether it's for a single post, a category archive, a search results page, etc.

Such issue could happen if you added the code "just like that" to your theme's functions file, so try doing it like so instead where I put the code inside a function which is hooked on wp:

add_action( 'wp', function () {
    if ( is_single() && 'post' == get_post_type() ) {
        remove_filter( 'get_the_excerpt', 'wp_trim_excerpt' );
} );

    You are absolutely right, it works. Thanks for the observation and solution! Commented Oct 19, 2022 at 16:18
