Question

我正在尝试使用以下代码建立活动页面链接。但是随着将来我添加更多页面，如果还有更多的话。有没有办法缩短它？

<?php  
$urlarray=explode('/', $_SERVER["REQUEST_URI"]);
$pageActive = end($urlarray); 
$dashClass ='';  
$userClass = '';
$settingClass = '';
$activePage = array(
    "dashboard",
    "settings",
    "users"
);

if(in_array($pageActive, $activePage)) { 
    if($pageActive == 'users'){
        $userClass = 'class="active"';
    }else if($pageActive == 'dashboard'){
        $dashClass = 'class="active"';
    }else if($pageActive == 'settings'){
        $settingClass = 'class="active"';
    }
    ...
    ...
    ...
} 
?>

在此处回显html

<ul>
  <li <?php echo $dashClass;?>></li>
  <li <?php echo $userClass;?>></li>
  <li <?php echo $settingClass;?>></li> 
</ul>

Answer 1

使用switch

switch($pageActive) {
    // Users
    case 'users':
        $userClass = 'class="active"'
        break;

    // Dash
    case 'dashboard':
        $dashClass = 'class="active"'
        break;

    //something else
    case 'something-else':
        $somethingElseClass = 'class="blah"'
        break;

    // Default fallback one
    default:
        $userClass = 'class="active"';
        break;
}

编辑您可以做

<li <?php if($pageActive === 'user'){ echo 'class="active"'; } ?>User</li>
<li <?php if($pageActive === 'dashboard'){ echo 'class="active"'; } ?>>Dashboard</li>

Answer 2

它们已经是一个包含菜单项列表的数组，名称为“ activePage”。您可以尝试以下代码。

<?php
$urlarray=explode('/', $_SERVER["REQUEST_URI"]);
$pageActive = end($urlarray); 
$activePage = array('dashboard', 'settings', 'users');
?>

<ul>
    <?php
        foreach($activePage as $_key => $_value) {
            $menuSelect = '';
            if( in_array($pageActive, $activePage) ) {
                $menuSelect = 'class="active"';
            }
            ?><li <?php echo $menuSelect; ?>><?php echo $_value; ?></li><?php
        }
    ?>
</ul>

缩短活动页面链接的else else语句
