更改gravityforms提交的Wordpress用户角色

Question

我正在使用Gravityforms和用户注册附加组件，并有一个表单，当提交时，应该改变当前用户的角色到一个新的角色，没有任何潜在的条件。

使用gravity\forms docs https://docs.gravityforms.com/gform_user_updated/#1-update-user-role并尝试执行以下操作：

add_action( 'gform_user_updated_3', 'change_role', 10, 3 );
function change_role( $user_id, $feed, $entry, $user_pass ) {

    global $current_user;
    get_currentuserinfo();
    $user_id = $current_user->ID;

    echo $user_id;
    if( ! $user_id ) {
        return;
    }
    $user = new WP_User( $user_id );
    $user->set_role( 'role' );     // update 'role' to the name of the desired role

}   

但是它不起作用！有谁知道为什么这是不正确的，或者对代码进行了任何其他修改吗？

当我将你的代码与Gravity文档进行比较时，我看到了一些东西。

以下是添加了一些注释的代码：

add_action( 'gform_user_updated_3', 'change_role', 10, 3 );

function change_role( $user_id, $feed, $entry, $user_pass ) {

    global $current_user; //  you probably don't need this
    get_currentuserinfo(); // you probably don't need this
    $user_id = $current_user->ID; // $user_id should already be a numeric value passed in to the function containing the logged in user's ID so you shouldn't need to do this. You're resetting the $user_id variable here to whatever is being pulled out of the get_currentuserinfo() function, and I'm guessing that's the problem

    //I would get rid of this echo and if statement
    echo $user_id;
    if( ! $user_id ) {
        return;
    }

    $user = new WP_User( $user_id );
    $user->set_role( 'role' ); // the word "role" here needs to be the role name

}

我想你可以把它简化一些。试着这样做：

add_action( 'gform_user_updated_3', 'change_role', 10, 3 );

function change_role( $user_id, $feed, $entry, $user_pass ) {

    $user = new WP_User( $user_id );
    $user->set_role( 'new_role_name_here' ); // Add an existing role here to update the user too

}
