我現在正在爲這一天掙扎半天,我似乎無法做到。我在我的wordpress網站有一個自定義功能,它會自動創建一個摘錄。這一切都很順利,但對於一些(我想邏輯)的原因,它也切斷了<br />
標籤,因爲它有一個空間。Preg_split擰緊BR標籤?
如何解決這個問題?這與preg_split函數有關嗎?
下面是我的代碼:
function custom_wp_trim_excerpt($text) {
$raw_excerpt = $text;
if ('' == $text) {
//Retrieve the post content.
$text = get_the_content('');
//Delete all shortcode tags from the content.
$text = strip_shortcodes($text);
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$allowed_tags = '<p>,<br>,<br/>,<br />,<a>,<em>,<strong>,<img>'; /*** MODIFY THIS. Add the allowed HTML tags separated by a comma.***/
$text = strip_tags($text, $allowed_tags);
$excerpt_word_count = 40; /*** MODIFY THIS. change the excerpt word count to any integer you like.***/
$excerpt_length = apply_filters('excerpt_length', $excerpt_word_count);
$excerpt_end = ' <a href="'. get_permalink($post->ID) . '">' . '...' . '</a>';
$excerpt_more = apply_filters('excerpt_more', ' ' . $excerpt_end);
$words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
if (count($words) > $excerpt_length && $words) {
array_pop($words);
$text = implode(' ', $words);
$text = $text . $excerpt_more;
} else {
$text = implode(' ', $words);
}
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_wp_trim_excerpt');
謝謝!
謝謝,這幫了我! – RobbertT 2013-04-26 09:19:57
