Consulte la clase WP_User ;puede usarlapara agregar yeliminar rolesparaun usuario.

EDITAR: Realmente debería haberproporcionadomásinformación conesta respuestainicialmente,así que agregarémásinformación a continuación.

Másespecíficamente,el rol de un usuario sepuedeestablecer creando unainstancia de la clase WP_user y llamando a losmétodos add_role() o remove_role().

Ejemplo

Cambiar lafunción de un suscriptor aeditor

 // NOTE: Of course change 3 to the appropriate user ID
$u = new WP_User( 3 );

// Remove role
$u->remove_role( 'subscriber' );

// Add role
$u->add_role( 'editor' );
 

Con suerte,eso serámás útil quemi respuestainicial,quenofuenecesariamentetan útil.

See the WP_User class, you can use this to add and remove roles for a user.

EDIT: I really should have provided more information with this answer initially, so i'm adding more information below.

More specifically, a user's role can be set by creating an instance of the WP_user class, and calling the add_role() or remove_role() methods.

Example

Change a subscribers role to editor

// NOTE: Of course change 3 to the appropriate user ID
$u = new WP_User( 3 );

// Remove role
$u->remove_role( 'subscriber' );

// Add role
$u->add_role( 'editor' );

Hopefully that's more helpful than my initial response, which wasn't necessarily as helpful.

Solotengaen cuenta que hay unaformamás sencilla de cambiarel rol del usuario queesespecialmente útil cuandono conoceel rol actual del usuario: ->set_role()

Ejemplo:

 // Fetch the WP_User object of our user.
$u = new WP_User( 3 );

// Replace the current role with 'editor' role
$u->set_role( 'editor' );
 

Just note that there is a simpler way to change the user role which is especially helpful when you do not know the current role of the user: ->set_role()

Example:

// Fetch the WP_User object of our user.
$u = new WP_User( 3 );

// Replace the current role with 'editor' role
$u->set_role( 'editor' );

Paraextrapolar la respuesta det31os,puede agregar algo comoestoen su archivo defunciones si desea hacerloprogramáticamenteen función de una condición

 $blogusers = get_users($blogID.'&role=student');

foreach ($blogusers as $user) {

    $thisYear = date('Y-7');
    $gradYear = date(get_the_author_meta( 'graduation_year', $user->ID ).'-7');

    if($gradYear < $thisYear) {
        $u = new WP_User( $user->ID );
        // Remove role
        $u->remove_role( 'student' );

        // Add role
        $u->add_role( 'adult' );
    }
}
 

To extrapolate on t31os's answer you can slap something like this in your functions file if you want to do this programmatically based on a condition

$blogusers = get_users($blogID.'&role=student');

foreach ($blogusers as $user) {

    $thisYear = date('Y-7');
    $gradYear = date(get_the_author_meta( 'graduation_year', $user->ID ).'-7');

    if($gradYear < $thisYear) {
        $u = new WP_User( $user->ID );
        // Remove role
        $u->remove_role( 'student' );

        // Add role
        $u->add_role( 'adult' );
    }
}

Puede cambiarel rol de cualquier usuarioeditandoelperfil del usuario.Noesnecesario agregarmás código cuandoesta opción yaestáintegradaen WordPress.

O

Puede usar códigopara cambiartodos los usuarios actuales con lafunción de suscriptor aeditor:

 $current_user = wp_get_current_user();

// Remove role
$current_user->remove_role( 'subscriber' );

// Add role
$current_user->add_role( 'editor' );
 

You can change the role of any user by editing the users profile. No need to add any more code when this option is already built into WordPress.

Or

You could use code to change all current users with the subscriber role to editor:

$current_user = wp_get_current_user();

// Remove role
$current_user->remove_role( 'subscriber' );

// Add role
$current_user->add_role( 'editor' );

¡Hay unafunción de WordPressparaeso!

Creo queesmejor utilizar lasfunciones de WordPress,siempre y cuandoestén disponibles.

Puede utilizar lafunción wp_insert_user () ,donde uno de los argumentos quenecesitaráproporcionares $ userdata ['rol'].Eneste argumento,puedeespecificarel rol al que desea cambiar al usuario.

There's a WordPress function for that!

I think it is best to use WordPress functions, if and when they are available.

You can use the wp_insert_user() function, where one of the arguments that you will need to provide is the $userdata['role']. In this argument you can specify the role that you want to change the user into.

tienes queincluir/wp-includes/registration.php,si usasel código como un scriptindependiente. Saludos Uwe

you have to include the /wp-includes/registration.php, if you use the code as a stand alone script. Regards Uwe

Puede utilizar wp_update_user .Tu código debe ser así:

 <?php
    $user_id = 3;
    $new_role = 'editor';

    $result = wp_update_user(array('ID'=>$user_id, 'role'=>$new_role));

    if ( is_wp_error( $result ) ) {
        // There was an error, probably that user doesn't exist.
    } else {
        // Success!
    }
?>
 

You can use wp_update_user. Your code shoud be like this:

<?php
    $user_id = 3;
    $new_role = 'editor';

    $result = wp_update_user(array('ID'=>$user_id, 'role'=>$new_role));

    if ( is_wp_error( $result ) ) {
        // There was an error, probably that user doesn't exist.
    } else {
        // Success!
    }
?>

 <?php
$wuser_ID = get_current_user_id();
if ($wuser_ID)
    {
      // NOTE: Of course change 3 to the appropriate user ID
      $u = new WP_User( $wuser_ID );

      // Remove role
      $u->remove_role( 'subscriber' );

      // Add role
      $u->add_role( 'contributor' );
    }
?>
 

<?php
$wuser_ID = get_current_user_id();
if ($wuser_ID)
    {
      // NOTE: Of course change 3 to the appropriate user ID
      $u = new WP_User( $wuser_ID );

      // Remove role
      $u->remove_role( 'subscriber' );

      // Add role
      $u->add_role( 'contributor' );
    }
?>

Sé quees unapublicaciónmuy antigua,pero descubrí que los roles de los usuarios se almacenanen latabla wp_usermeta con la clave wp_capabilities en meta_key columna.

Si desea cambiarel rol de usuario,puede hacerlo conesta sencillafunción.

 función change_role ($id,$new_role) {
    GLOBAL $table_prefix;
 if (is_array ($new_role)) {
        $new_role_array=$new_role;
    }más{
        $new_role_array=array ($new_role=>true);
    }
    return update_user_meta ($id,$table_prefix.'capabilities ',$new_role_array);
}
 

Hay dosformas de utilizarestafunción.

Si desea cambiar lafunciónpor una únicafunción.

  change_role (2,'editor');//editoreselnuevo rol
 

O si desea agregarmúltiples roles al usuario,use los roles comomatrizen el segundoparámetro.

  $ roles_array=array ('editor'=>true,'administrator'=>true);//matriz de roles
change_role (2,$ roles_array);
 

Buena suerte.

I know its a very old Post, but i have found that the roles for users are stored in wp_usermeta table with key wp_capabilities in meta_key column.

If you want to change the user role you can do it by this simple function.

function change_role($id, $new_role){
    GLOBAL $table_prefix;
    if(is_array($new_role)){
        $new_role_array = $new_role;
    }else{
        $new_role_array = array( $new_role => true );
    }
    return update_user_meta($id, $table_prefix.'capabilities', $new_role_array);
}

There is two way to use this function.

If you want to change the role for a single role.

change_role(2, 'editor'); // editor is the new role

Or if you want to add multi roles to the user, use the roles as array in the second parameter.

$roles_array = array('editor' => true, 'administrator' => true); // roles array
change_role(2, $roles_array);

Good luck.
