I am using this function to limit the excerpt to the first sentence...

function hello_first_sentence( $string ) {
 
    $sentence = preg_split( '/(\.|!|\?)\s/', $string, 2, PREG_SPLIT_DELIM_CAPTURE );
    return $sentence['0'] . $sentence['1'];
 
} add_filter( 'get_the_excerpt', 'hello_first_sentence', 10, 1 ); 

However, for some reason, I am unable to add the "read more" after the excerpt... any help?

• excerpt

• Where's the code with your attempt of what you're trying to do? – mozboz Commented Jul 25, 2020 at 18:22
• I have another function for that, but it doesn't work.function hello_excerpt_more($more) { global $post; return '... <span class="moretag">[+]</span>'; } add_filter( 'excerpt_more', 'new_excerpt_more' ); – PauloP Commented Jul 26, 2020 at 11:43
• It's useful to add specifically what you're trying to do and what you've tried to the question. 'It doesn't work' doesn't provide any information about what you actually want the outcome to be. – mozboz Commented Jul 26, 2020 at 13:40
• I want that after the excerpt, which was customized to show only the first sentence, to have "Read More". – PauloP Commented Jul 26, 2020 at 15:57
• 1 Do you mean you want this: return $sentence['0'] . $sentence['1'] . "... Read More"; ? – mozboz Commented Jul 26, 2020 at 16:04

To append strings in PHP use ., like:

return $sentence['0'] . $sentence['1'] . "... Read More";
