Wordpress capabilities and current_user_can() in functions.php
提问by ItsGeorge
I have added a function to functions.php to redirect users to posts-new.php after login and it works. However, I only want this to happen if the user logging in is a contributor. So I added the following:
我在functions.php 中添加了一个函数，用于在登录后将用户重定向到posts-new.php 并且它工作正常。但是，如果登录的用户是贡献者，我只希望发生这种情况。所以我添加了以下内容：
/** Redirect after login */
function mysite_login_redirect(){
if ( current_user_can( 'manage_options' ) ) {
return 'http://mysite.com/wp-admin/index.php';}
else {
return 'http://mysite.com/wp-admin/post-new.php';}
}
add_action( 'login_redirect', 'mysite_login_redirect');
In this state, both contributors and admins are redirected to post-new.php. To test it I modified the function so that users without the capability would be redirected:
在这种状态下，贡献者和管理员都被重定向到 post-new.php。为了测试它，我修改了该功能，以便将没有该功能的用户重定向：
if ( !current_user_can( 'ma ...
when I modified the function, both contributors and admins are redirected to index.php.
当我修改函数时，贡献者和管理员都被重定向到 index.php。
So the function seems to work but this implies to me that it's not seeing the 'manage_options' capability for admins. I've tried several admin-exclusive capabilities with the same results. Weird huh?
所以该功能似乎有效，但这对我来说意味着它没有看到管理员的“manage_options”功能。我尝试了几种管理员专有功能，结果相同。很奇怪吧？
I should say that I am using the user role-editor-plugin but I disabled it and tested the functions with the same results.
我应该说我正在使用用户角色编辑器插件，但我禁用了它并测试了具有相同结果的功能。
I'm also using Active Directory Integration and Admin Menu Editor.
我也在使用 Active Directory 集成和管理菜单编辑器。

Try this:
尝试这个：
if( current_user_can( 'administrator' ) ){} // only if administrator
if( current_user_can( 'editor' ) ){} // only if editor
if( current_user_can( 'author' ) ){} // only if author
if( current_user_can( 'contributor' ) ){} // only if contributor
if( current_user_can( 'subscriber' ) ){} // only if subscriber
Or:
或者：
if( current_user_can( 'level_10' ) ){}
if( current_user_can( 'level_9' ) ){}
if( current_user_can( 'level_8' ) ){}
if( current_user_can( 'level_7' ) ){}
if( current_user_can( 'level_6' ) ){}
if( current_user_can( 'level_5' ) ){}
if( current_user_can( 'level_4' ) ){}
if( current_user_can( 'level_3' ) ){}
if( current_user_can( 'level_2' ) ){}
if( current_user_can( 'level_1' ) ){}
if( current_user_can( 'level_0' ) ){}

Try this:
尝试这个：
$exclude_role = 'contributor';
$roles = get_role( $exclude_role )->capabilities;
foreach ( $roles as $cap ) {
if ( current_user_can( $cap ) ) {
...
}
}
