这里有一个函数,它可以保持HTML标记的灵活性,在摘录的末尾添加一个“阅读更多”链接,并在第一段后修剪摘录。
if ( ! function_exists( \'wpse0001_custom_wp_trim_excerpt\' ) ) :
function wpse0001_custom_wp_trim_excerpt($wpse0001_excerpt) {
global $post;
$raw_excerpt = $wpse0001_excerpt;
if ( \'\' == $wpse0001_excerpt ) {
$wpse0001_excerpt = get_the_content(\'\');
$wpse0001_excerpt = strip_shortcodes( $wpse0001_excerpt );
$wpse0001_excerpt = apply_filters(\'the_content\', $wpse0001_excerpt);
$wpse0001_excerpt = substr( $wpse0001_excerpt, 0, strpos( $wpse0001_excerpt, \'</p>\' ) + 4 );
$wpse0001_excerpt = str_replace(\']]>\', \']]>\', $wpse0001_excerpt);
$excerpt_end = \' <a href="\'. esc_url( get_permalink() ) . \'">\' . \' » \' . sprintf(__( \'Read more about: %s »\', \'pietergoosen\' ), get_the_title()) . \'</a>\';
$excerpt_more = apply_filters(\'excerpt_more\', \' \' . $excerpt_end);
//$pos = strrpos($wpse0001_excerpt, \'</\');
//if ($pos !== false)
// Inside last HTML tag
//$wpse0001_excerpt = substr_replace($wpse0001_excerpt, $excerpt_end, $pos, 0);
//else
// After the content
$wpse0001_excerpt .= $excerpt_end;
return $wpse0001_excerpt;
}
return apply_filters(\'wpse0001_custom_wp_trim_excerpt\', $wpse0001_excerpt, $raw_excerpt);
}
endif;
remove_filter(\'get_the_excerpt\', \'wp_trim_excerpt\');
add_filter(\'get_the_excerpt\', \'wpse0001_custom_wp_trim_excerpt\');
请注意,“阅读更多”将出现在新段落中,如果您需要最后一个单词旁边的“阅读更多”,只需删除
//
来自此代码
//$pos = strrpos($wpse0001_excerpt, \'</\');
//if ($pos !== false)
// Inside last HTML tag
//$wpse0001_excerpt = substr_replace($wpse0001_excerpt, $excerpt_end, $pos, 0);
//else
// After the content
EDIT
你还是会打电话的
the_excerpt()
通常在模板文件中使用
the_excerpt()
