使用Smarty修改器

Question

我在smartys网站上发现了这个Smarty修饰符，它是一个将bbcode转换为html的帖子，但我找不到或者没有说出使用它的语法是什么。

{$bbcode_here|bbcode2html}

有人可以告诉或告诉我如何使用这个Smarty修饰符如下。

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

正确使用此函数将首先将代码放在PHP文件中，该文件将加载调用smarty模板。我假设你已经设置好并且正在运行。

您必须稍微更改一下功能参数，如下所示：

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>",
      '/(?<!\\\\)\[u(?::\w+)?\](.*?)\[\/u(?::\w+)?\]/si'                 => "<span style=\"text-decoration:underline\">\\1</span>",
      '/(?<!\\\\)\[center(?::\w+)?\](.*?)\[\/center(?::\w+)?\]/si'       => "<div style=\"text-align:center\">\\1</div>",

      // [code] & [php]
      '/(?<!\\\\)\[code(?::\w+)?\](.*?)\[\/code(?::\w+)?\]/si'           => "<div class=\"bb-code\">\\1</div>",
      '/(?<!\\\\)\[php(?::\w+)?\](.*?)\[\/php(?::\w+)?\]/si'             => "<div class=\"bb-php\">\\1</div>",
      // [email]
      '/(?<!\\\\)\[email(?::\w+)?\](.*?)\[\/email(?::\w+)?\]/si'         => "<a href=\"mailto:\\1\" class=\"bb-email\">\\1</a>",
      '/(?<!\\\\)\[email(?::\w+)?=(.*?)\](.*?)\[\/email(?::\w+)?\]/si'   => "<a href=\"mailto:\\1\" class=\"bb-email\">\\2</a>",
      // [url]
      '/(?<!\\\\)\[url(?::\w+)?\]www\.(.*?)\[\/url(?::\w+)?\]/si'        => "<a href=\"http://www.\\1\" target=\"_blank\" class=\"bb-url\">\\1</a>",
      '/(?<!\\\\)\[url(?::\w+)?\](.*?)\[\/url(?::\w+)?\]/si'             => "<a href=\"\\1\" target=\"_blank\" class=\"bb-url\">\\1</a>",
      '/(?<!\\\\)\[url(?::\w+)?=(.*?)?\](.*?)\[\/url(?::\w+)?\]/si'      => "<a href=\"\\1\" target=\"_blank\" class=\"bb-url\">\\2</a>",

      // [list]
      '/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[\*(?::\w+)?\](.*?)(?=(?:\s*<br\s*\/?>\s*)?\[\*|(?:\s*<br\s*\/?>\s*)?\[\/?list)/si' => "\n<li class=\"bb-listitem\">\\1</li>",
      '/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[\/list(:(?!u|o)\w+)?\](?:<br\s*\/?>)?/si'    => "\n</ul>",
      '/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[\/list:u(:\w+)?\](?:<br\s*\/?>)?/si'         => "\n</ul>",

      '/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list:u(:\w+)?\]\s*(?:<br\s*\/?>)?/si'        => "\n<ul class=\"bb-list-unordered\">",
      '/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list:o(:\w+)?\]\s*(?:<br\s*\/?>)?/si'        => "\n<ol class=\"bb-list-ordered\">",
      '/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(?::o)?(:\w+)?=1\]\s*(?:<br\s*\/?>)?/si' => "\n<ol class=\"bb-list-ordered,bb-list-ordered-d\">",
      '/(?<!\\\\)(?:\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;
}

你需要在你的php文件中注册这个函数，一般在php文件中的函数之后注册函数，如下所示：

$smarty->register_block('bbcode2html', 'smarty_modifier_bbcode2html');

现在您已准备好在智能模板中使用它，如下所示：

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

Answer 2

这是将bbcode翻译成html。在这里查看bbcode参考：http://www.bbcode.org/reference.php
