我在函数中使用此代码。php：Issue with enabling formatting in excerpts in Wordpress

允许在摘录中使用短代码、javascript和格式-非常好，谢谢。

然而，我也使用了一个滑块（幻灯片播放卫星），如果我将摘录长度设置得太低（幻灯片大小显然与其内容相关），滑块就会断裂。有没有人知道如何保持摘录的长度较低，但当一篇文章有一个由短代码调用的播放器/滑块时，请确保它完成了嵌入的代码，无论它有多长？

谢谢

功能。php：

function better_trim_excerpt($text)
{
$raw_excerpt = $text;
if ( \'\' == $text ) {
    $text = get_the_content(\'\');
    //$text = strip_shortcodes( $text );
    $text = apply_filters(\'the_content\', $text);
    $text = str_replace(\']]>\', \']]>\', $text);


    // Enable formatting in excerpts - Add HTML tags that you want to be parsed in excerpts, default is 55
    //$text = strip_tags($text, \'<strong><b><em><i><a><code><kbd><img>\');

    // Set custom excerpt length - number of words to be shown in excerpts
    $excerpt_length = apply_filters(\'excerpt_length\', 900);

    // Modify excerpt more string at the end from [...] to ...
    $excerpt_more = apply_filters(\'excerpt_more\', \' \' . \'...\');

    $words = preg_split("/[\\n\\r\\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
    if ( count($words) > $excerpt_length ) {
        array_pop($words);
        $text = implode(\' \', $words);




        // IMPORTANT! Prevents tags cutoff by excerpt (i.e. unclosed tags) from breaking formatting
        $text = force_balance_tags( $text );

        $text = $text . $excerpt_more;
    } else {
        $text = implode(\' \', $words);
    }
}
return apply_filters(\'wp_trim_excerpt\', $text, $raw_excerpt);
}

// Remove the native excerpt function, and replace it with our improved function
remove_filter(\'get_the_excerpt\', \'wp_trim_excerpt\');
add_filter(\'get_the_excerpt\', \'better_trim_excerpt\');
