Php 使用Smarty修改器

我在smartys网站上找到了这个Smarty修饰符，它是一篇将bbcode转换为html的文章，但我找不到，或者它没有说明使用它的语法

{$bbcode_here|bbcode2html}

有人能告诉我或告诉我如何使用这个Smarty修饰符吗

function smarty_modifier_bbcode2html($message) {
  $preg = array(
          '/(?<!\\\\)\[color(?::\w+)?=(.*?)\](.*?)\[\/color(?::\w+)?\]/si'   => "<span style=\"color:\\1\">\\2</span>",

这是将bbcode翻译成html。请查看此处的bbcode参考：

正确使用此函数的方法是首先将代码放入PHP文件中，该文件将通过调用smarty模板加载。我假设您已经设置并运行smarty

您只需稍微更改功能参数，如图所示：

function smarty_modifier_bbcode2html($params, &$smarty) {
    $message = $params['message'];
    $preg = array(
      '/(?<!\\\\)\[color(?::\w+)?=(.*?)\](.*?)\[\/color(?::\w+)?\]/si'   => "<span style=\"color:\\1\">\\2</span>",
      '/(?<!\\\\)\[size(?::\w+)?=(.*?)\](.*?)\[\/size(?::\w+)?\]/si'     => "<span style=\"font-size:\\1\">\\2</span>",
      '/(?<!\\\\)\[font(?::\w+)?=(.*?)\](.*?)\[\/font(?::\w+)?\]/si'     => "<span style=\"font-family:\\1\">\\2</span>",
      '/(?<!\\\\)\[align(?::\w+)?=(.*?)\](.*?)\[\/align(?::\w+)?\]/si'   => "<div style=\"text-align:\\1\">\\2</div>",
      '/(?<!\\\\)\[b(?::\w+)?\](.*?)\[\/b(?::\w+)?\]/si'                 => "<span style=\"font-weight:bold\">\\1</span>",
      '/(?<!\\\\)\[i(?::\w+)?\](.*?)\[\/i(?::\w+)?\]/si'                 => "<span style=\"font-style:italic\">\\1</span>",

      '/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(?::o)?(:\w+)?=i\]\s*(?:<br\s*\/?>)?/s'  => "\n<ol class=\"bb-list-ordered,bb-list-ordered-lr\">",
      '/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(?::o)?(:\w+)?=I\]\s*(?:<br\s*\/?>)?/s'  => "\n<ol class=\"bb-list-ordered,bb-list-ordered-ur\">",

   );
   $message = preg_replace(array_keys($preg), array_values($preg), $message);
   return $message;
}

现在，您已经准备好在smarty模板中使用它，如下所示：

<p>{bbcode2html message=$messageToConvert}</p>

{bbcode2html message=$messageToConvert}

<p>{bbcode2html message=$messageToConvert}</p>
