php - 为drupal 6创建2个链接l（）而不是一个以添加2个链接类

Question

嗨，我正在尝试为 drupal 6 创建一个寻呼机

我有这个功能来创建一个寻呼机

function mytheme_prev_next($current_node = NULL, $op = 'p') 
{
    // Node types to include in paging
    $node_types = array('type');

    if ($op == 'p') {
        $sql_op = '<';
        $order = 'DESC';
    } elseif ($op == 'n') {
        $sql_op = '>';
        $order = 'ASC';
    } else {
        return NULL;
    }

    $output = NULL;
    foreach($node_types as $type) {
        $quoted_types[] = "'" . $type . "'";
    }
    $sql = "SELECT nid, title, created FROM {node} n
            WHERE created $sql_op %s
            AND type IN (" . implode(',', $quoted_types) . ")
            AND status = 1
            ORDER BY created $order
            LIMIT 1";
    $result = db_query($sql, $current_node->created, $type);
    $data = db_fetch_object($result);
    if (!isset($data->nid) || !$data->nid) {
        return NULL;
    }
    $options = array('attributes' => array('class' => 'prev'));
    return l($data->title, "node/$data->nid", $options , array('html' => TRUE));
}

基本上我想要做的是将它分解为 2 个 l() 函数，它们仍然显示相同的信息我只需要向它们添加不同的链接类这是主题模板中的一个函数

<a href class="prev"><span class="arrowLeft"><?php print mytheme_prev_next($node, 'p'); ?></span></a>
<a href class="next"><span class="arrowRight"><?php print mytheme_prev_next($node, 'n'); ?></span></a>

上面的 html 标记是我想要实现的

Answer 1

返回 html 字符串而不是 l()

// Instead of using the l()
if ($op == 'p') {
return '<a href="node/' . $data->nid . '" class="prev"><span class="arrowLeft"></span>         
</a>';
} else {
return '<a href="node/' . $data->nid . '" class="next"><span class="arrowRight"></span>   
</a>';
}
