WordPress检查用户角色功能(多个角色)？

我在玩弄check_user_role function 按AppThemes组合；如WordPress current\\u user\\u can codex页面所述。在AppThemes教程代码中，它引用了以下内容：

// example use for the current user
if ( appthemes_check_user_role( \'customer\' )
    _e( "You\'ve got access dude!", \'appthemes\' );
else
    _e( "Sorry man, no luck.", \'appthemes\' );

我想让它与一个以上的用户角色（即“customrole”、“subscriber”）一起工作，但如果不创建感觉像是重复代码的代码，就没有太多的运气。

我让它发挥作用的唯一方法是做以下事情：

if (appthemes_check_user_role( \'customrole\' ) || appthemes_check_user_role( \'author\' ) ) {
    _e( "You\'ve got access dude!", \'appthemes\' );
} else {
    _e( "Sorry man, no luck.", \'appthemes\' );
}

或者这个：

if (appthemes_check_user_role( \'customrole\' ) ) {
    _e( "You\'ve got access dude!", \'appthemes\' );
} if (appthemes_check_user_role( \'author\' )) {
    _e( "You\'ve got access dude!", \'appthemes\' );
}else{
    _e( "Sorry man, no luck.", \'appthemes\' );
}

我想知道是否有人对简化代码以用于多个角色有什么建议？

if ( wpse_99666_check_user_roles( array( \'customrole\', \'author\' ) ) ) _e( "You\'ve got access dude!", \'appthemes\' ); else _e( \'Sorry man, no luck.\', \'appthemes\' ); /** * Checks if a particular user has one or more roles. * * Returns true on first matching role. Returns false if no roles match. * * @uses get_userdata() * @uses wp_get_current_user() * * @param array|string $roles Role name (or array of names). * @param int $user_id (Optional) The ID of a user. Defaults to the current user. * @return bool */ function wpse_99666_check_user_roles( $roles, $user_id = null ) { if ( is_numeric( $user_id ) ) $user = get_userdata( $user_id ); else $user = wp_get_current_user(); if ( empty( $user ) ) return false; $user_roles = (array) $user->roles; foreach ( (array) $roles as $role ) { if ( in_array( $role, $user_roles ) ) return true; } return false; }
