将特定的类/id应用于菜单上的当前页面(PHP) [英] Apply a specific class/id to current page on menu (PHP)

问题描述

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>

我想要一些可以自动将class ="current"添加到我当前所在的页面的工具.链接(如您在上面的代码中可以看到的)就像domain.com/folder/biography或domain .com/folder/contacts，因此没有.php/.html等.

I'd like to have something that automatically adds a class="current" to the page I'm currently in. Links (as you can see in the code above) are like domain.com/folder/biography or domain.com/folder/contacts, so without .php/.html, etc.

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>

但是它不起作用...带有strops的解决方案似乎是可行的，可能是我做错了..:P

But it doesn't work... the solution with strops seems viable, probably I'm doing it wrong.. :P

推荐答案

您应该:

1. 用!== false检查strpos()的结果.
2. 使用$_SERVER['REQUEST_URI']而不是$_SERVER['PHP_SELF'].
3. 将代码包装在函数中.

1. check the result of strpos() with !== false.
2. Use $_SERVER['REQUEST_URI'] rather than $_SERVER['PHP_SELF'].
3. Wrap the code inside a function.

类似这样的东西:

<?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>
