the_excerpt（）的多个“更多”链接; 在Wordpress中

Question

I've changed my excerpt link in wordpress from "[...]" to "Read More" with the code below. I want to know if there is a way to use more than one link for the excerpt. Let's say for posts in one category have "Read More" for their excerpt, and then posts in another category have "See Photos" for their excerpt link. is this possible?

remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_trim_excerpt');

function custom_trim_excerpt($text) { // Fakes an excerpt if needed
global $post;
if ( '' == $text ) {
$text = get_the_content('');
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$text = strip_tags($text);
$excerpt_length = 24;
$words = explode(' ', $text, $excerpt_length + 1);
if (count($words) > $excerpt_length) {
array_pop($words);
array_push($words, '...<br /><a href="'.get_permalink().'" class="tag">Read More</a>');
$text = implode(' ', $words);
}
}
return $text;
}

Answer 1

yes you can do it. use excerpt_more filter to change the "[...]" and in_category function to check the category for read more text.

try this code.

function custom_excerpt_more( $more ) {
    $read_more_txt = 'Read More..';

    if (in_category('cat_slug'))
        $read_more_txt = 'See Photos..';
    else if (in_category('cat_slug2'))
        $read_more_txt = 'Something else..';

    return ' <a title="'. $read_more_txt .'" href="'. get_permalink( get_the_ID() ) .'">'.   $read_more_txt .'</a>'; 
} 
add_filter( 'excerpt_more', 'custom_excerpt_more' );
