php中带有函数的图像链接

Question

我有一个关于函数的问题。

function &formatName($id, $name, $clanId, $clanSym, $clanCol)
{
    static $cache = array();

    if (!isset($cache[$name])) {
        $cache[$name] = esc($name);

        if ($id !== NULL) {
            $cache[$name] = '<a href="' . esc('player_info.php?target=' . $id) .
             '">' . $cache[$name] . '</a>';
        } else {
            $cache[$name] = "<s>{$cache[$name]}</s>";
        }

        if ($clanId !== NULL && $clanId != 0) {
            $cache[$name] = "(<span style=\"color: #$clanCol;\">" .
             htmlentities($clanSym) . "</span>) " . $cache[$name];
        }
    }

    return $cache[$name];
}

//打印$player的可点击名称

function print_name($player)
{
    global $db_name, $user_options;
    static $cache = array();

    if (!isset($cache[$player['login_name']])) {//this user not cached
        $pQuery = mysql_query("select u.login_id, u.login_name, u.clan_id, u.clan_sym_color,u.clan_sym from ${db_name}_users u where u.login_id = '$player[login_id]'");
        $player = mysql_fetch_assoc($pQuery);

        $cache[$player['login_name']] = formatName($player['login_id'],
         $player['login_name'], $player['clan_id'], $player['clan_sym'],
         $player['clan_sym_color']);
    }

    return $cache[$player['login_name']];
}

上面的函数打印一个带有玩家名字的链接。 我想在链接上放置一张桌子或某种装饰背景。 我有什么办法可以做到这一点？ 感谢您的阅读。

Answer 1

只需换行：

$cache[$name] = '<a href="' . esc('player_info.php?target=' . $id) . '">' . $cache[$name] . '</a>';

到

$cache[$name] = '<span class="link-decorator">';
$cache[$name] .= '<a href="' . esc('player_info.php?target=' . $id) .
             '">' . $cache[$name] . '</a>';
$cache[$name] .= '</span>';

然后您可以使用 CSS 设置链接和周围跨度的样式：

span.link-decorator { border: 3px solid #789abc; }
span.link-decorator a { color: red; }
span.link-decorator a:hover { color: blue; }
span.link-decorator a:visited { color: green; }

Answer 2

您可以在链接周围放置一个跨度并为其添加样式，这将比设置链接样式更灵活。

$cache[$name] = '<span style="background-image: url(image.jpg);"><a href="' . esc('player_info.php?target=' . $id) . '">' . $cache[$name] . '</a></span>';
