in the documentation - affectedRows();

Displays the number of affected rows, when doing “write” type queries (insert, update, etc.).

My code:

PHP Code:

// Method in model
function editClient($id = '', $FIELDS = [])
{
    $db = $this->db->table('WK_clients');

    $db
        ->where('id', (int)$id)
        ->update($FIELDS);

    $FIELDS['id'] = $id;

    return $db->affectedRows() ? $FIELDS : false;
} 


As a result, I get the error:
Call to undefined method CodeIgniter\\Database\\MySQLi\\Builder::affectedRows()

Please tell me what I'm doing wrong.

Have you tried :
$this->db->affectedRows()
instead of :
$db->affectedRows()

[Dedov_Evgeniy]

This is how it works. Not very logical. If you work with Query Builder Class, then these methods should also be there, at least you can just make a mistake. And this also applies to the method -> insertID ()

[vincent78]

You're right !

An other solution is :
the method update() should return FALSE if failure and the number of affected rows if success

The signature of the method would be :
public function update($withAffectedRows = FALSE)

It's better with a parameter because we don't always want the number of affected rows and it costs a query ...

My mistake, the method affectedRows() doesn't perform a database query ...
