Question

我有这个数组：

我只需要向管理员显示此内容。我尝试使用if

$avia_pages = array(
    array('slug' => 'avia',   'parent'=>'avia', 'icon'=>"new/spanner-screwdriver-7@3x.png" , 'title' =>  __('Theme Options', 'avia_framework')),
    array('slug' => 'layout', 'parent'=>'avia', 'icon'=>"new/window-within-7@3x.png",        'title' =>  __('General Layout', 'avia_framework')), 
);

但是它不起作用，我遇到了PHP错误。

有关更多信息，我在Wordpress 5.1中使用了“折叠主题”

我做错了什么？

您可以调用函数current_user_can并将角色管理员作为参数传递。

<?php if( current_user_can('administrator') ) { ?> 
    // stuff here for admins
<?php } else { ?>
    // stuff here for not admins
<?php } ?>

但是，current_user_can不仅可以与用户角色名称一起使用，还可以与功能一起使用。

<?php if( current_user_can('edit_others_pages') ) { ?> 
    // stuff here for user roles that can edit pages: editors and 
administrators
<?php } ?>

请查看here，以获取有关功能的更多信息。

仅向管理员显示阵列中的项目
