Gera um erro ao inserir na tabela

Notice: Undefined index: data in C:\xampp\htdocs\Gestao\insert.php on line 14

Notice: Undefined index: login_id in C:\xampp\htdocs\Gestao\insert.php on line 15

Warning: mysqli_error() expects exactly 1 parameter, 0 given in C:\xampp\htdocs\Gestao\insert.php on line 18

Alguem me dá ajuda,

Confirma os ids que estás a usar para enviar e processar dados. Por exemplo, tens $_REQUEST['data'], mas foi mesmo data que usaste no form ao enviar os dados?

Quanto ao problema do mysqli_error(), confirma se está a passar à função os parâmetros definidos na documentação.
