发生数据库错误：您必须使用“set”方法来更新条目

Question

This is the code:

$this->db->where('id', $id);
return $this->db->update('contractors', ((array) $contractor));

And it gives me the error A Database Error Occurred: You must use the "set" method to update an entry.

Answer 1

Your question is missing the $contractor array so I might be wrong here, but when I get this error in CI, it's usually because I dont' have my update/insert data array correctly formatted with key/value pairs.

$contractor = array(
"name" => "John",
"phone" => "123-123-1234"
);
$this->db->where('id', $id);
return $this->db->update('contractors', $contractor);
