我有一个这样的菜单：
<div id="blahblah" style="blahblah">
<a href="http://domain.com/folder/biography"><img style="blahblah" src="blahblahblahblah"></a>
<a href="http://domain.com/folder/contacts"><img style="blahblah" src="blahblahblahblah"></a>
<a href="http://domain.com/folder/gallery"><img style="blahblah" src="blahblahblahblah"></a>
<a href="http://domain.com/folder/dontknow"><img style="blahblah" src="blahblahblahblah"></a>
</div>
我想要有一些东西可以自动将 class="current" 添加到我当前所在的页面。链接（如您在上面的代码中看到的）类似于domain.com/folder/biography 或domain.com/文件夹/联系人，因此没有 .php/.html 等。
我尝试过：
<div id="blahblah" style="blahblah">
<a <?php if (strpos($_SERVER['PHP_SELF'], 'biography')) echo 'class="current"';?> href="http://domain.com/folder/biography"><img style="blahblah" src="blahblahblahblah"></a>
<a <?php if (strpos($_SERVER['PHP_SELF'], 'contacts')) echo 'class="current"';?> href="http://domain.com/folder/contacts"><img style="blahblah" src="blahblahblahblah"></a>
...
...
</div>
但它不起作用...带 strops 的解决方案似乎可行，可能我做错了..：P
你应该：
- 检查结果
strpos() with !== false.
- Use
$_SERVER['REQUEST_URI']而不是$_SERVER['PHP_SELF'].
- 将代码包装在函数内。
像这样的东西：
<?php
function get_current($name) {
if (strpos($_SERVER['REQUEST_URI'], $name) !== false)
echo 'class="current"';
}
?>
<div id="blahblah" style="blahblah">
<a <?php get_current('biography') ?> href="http://domain.com/folder/biography"><img style="blahblah" src="blahblahblahblah"></a>
<a <?php get_current('contacts') ?> href="http://domain.com/folder/contacts"><img style="blahblah" src="blahblahblahblah"></a>
...
...
</div>
