我正试图在一页上获得2个短代码（单包含和单概况）。问题是，只执行第一个短代码。简单页面上的第二个短代码返回短代码字符串。

此代码位于插件中：

add_filter(\'the_content\', \'initQmediaRechnerSnippet\');
function initQmediaRechnerSnippet($content)
{
    $pattern = "/\\[([^=]*)=?(.*)?\\]/";

    if (preg_match($pattern, $content, $treffer))
    {
        $snippetName = $treffer[1];
        $snippet = \'\';
        switch ($snippetName) {
            case \'kreditkarte\':
                $snippet = qRechnerInclude(API_CALC_KREDITKARTE, \'\');
                $content = str_replace(\'[\' . $snippetName . \']\', $snippet, $content);
                break;
            case \'single-include\':
                list($ids, $product) = explode(":", $treffer[2]);
                $snippet = qRechnerInclude(str_replace(\'$PRODUCT$\', $product, API_CALC_SINGLEINCLUDE . $ids), \'\');
                $content = str_replace(\'[\' . $snippetName . \'=\' . $ids . \':\' . $product . \']\', $snippet, $content);
                break;
            case \'single-factsheet\':
                list($ids, $product) = explode(":", $treffer[2]);
                $snippet = qRechnerInclude(str_replace(\'$PRODUCT$\', $product, API_CALC_SINGLEFACTSHEET . $ids), \'\');
                $content = str_replace(\'[\' . $snippetName . \'=\' . $ids . \':\' . $product . \']\', $snippet, $content);
                break;
            default:
                ;
                break;
        }
    }
    return $content;
}

我怎样才能让它工作？（删除中断不起作用）将preg\\u match替换为preg\\u match\\u all会停止所有短代码的执行。
