Limit content size

时间：2012-02-09 作者：Scoobie

有人知道我如何在使用“content=yes”函数时限制帖子的字符长度吗？

我需要一些像excerpt\\U大小的东西，但用于内容，而不是excerpt。在有人建议使用摘录之前，它去掉了格式和换行符，所以我想使用内容输出功能，但要设置一个限制，就像使用摘录\\u大小一样。我希望这对你有意义。

如果有人知道我需要在插件中修改什么，我不介意在插件中修改php。

提前感谢！

您可以启用链接、图像和其他标记以用于\\u摘录。这可能是最简单的解决方案，但它将适用于all excerpts:

<?php
function my_excerpt_custom($text) {
$raw_excerpt = $text;
if ( \'\' == $text ) {
    $text = get_the_content(\'\');
    $text = strip_shortcodes( $text ); 
    $text = apply_filters(\'the_content\', $text);
    $text = str_replace(\']]>\', \']]&gt;\', $text);
    $allowed_tags = \'<a>,<p>,<img>\';
    $text = strip_tags($text, $allowed_tags);

    $excerpt_word_count = 88; /*** MODIFY THIS. change the excerpt word count to any integer you like.***/
    $excerpt_length = apply_filters(\'excerpt_length\', $excerpt_word_count);

    // $excerpt_end = \'[...]\'; /*** MODIFY THIS. change the excerpt endind to something else.***/
    $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) > $excerpt_length ) {
        array_pop($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\', \'my_excerpt_custom\');
?>

我从这里找到的代码中添加了一些最有可能的标记：bac consulting website

您不能只在任何位置上切断内容：中断可能发生在元素内部，如table, blockquote 或pre. 每个脚本执行此操作的唯一方法：使用DOM parser, 遍历已解析的文档树，计算每个元素中的字符数，如果处于安全上下文中，请停止。非常困难。

唯一安全的方法是使用the_content() 和amanually set  标记。

将摘录大小编辑为任意大小。
