我试图使用update()更新数据库，但其中没有id。相反，我有一个名为kwt的主键。
每次我尝试执行update()时，查询总是引用table.id而不是table.kwt
UPDATE `zakat` SET `nama` = :nama:, `alamat` = :alamat:, `telp` = :telp:, `jmlhjiwa` = :jmlhjiwa:, `berasbeli` = :berasbeli:, `ttlbeli` = :ttlbeli:, `berasbawa` = :berasbawa:, `ttlberas` = :ttlberas:, `maal` = :maal:, `berasinfaq` = :berasinfaq:, `infaq` = :infaq:, `fidyah` = :fidyah:, `penerima` = :penerima: WHERE `zakat`.`id` IN :zakat.kwt:
我需要使WHERE 'zakat'.'id'变成WHERE 'zakat'.'kwt'
这是我的控制器：
public function update($kwt)
{
$beli = $this->request->getvar('berasbeli');
$this->zakatModel->update(
[
'kwt' => $kwt,
'nama' => $this->request->getVar('nama'),
'alamat' => $this->request->getVar('alamat'),
'telp' => $this->request->getvar('telp'),
'jmlhjiwa' => $this->request->getVar('jmlhjiwa'),
'berasbeli' => $this->request->getVar('berasbeli'),
'ttlbeli' => (int)$beli * 38000,
'berasbawa' => $this->request->getvar('berasbawa'),
'ttlberas' => $this->request->getvar('berasbawa') + $this->request->getVar('berasbeli'),
'maal' => $this->request->getVar('maal'),
'berasinfaq' => $this->request->getVar('berasinfaq'),
'infaq' => $this->request->getvar('infaq'),
'fidyah' => $this->request->getVar('fidyah'),
'penerima' => $this->request->getVar('penerima')
]
);
session()->setFlashdata('pesan', 'Upload Berhasil');
return redirect()->to('/');
}

对于我的模型，我还没有写任何东西，因为我的教程模型中没有写任何内容。当我使用save()而不是update()时，它将创建具有相同主键的新数据。
它需要表的id来更新数据；您的id已被遗忘
看看我的示例
function dommy($id, $data){
$myModel = new MyModel();
$myModel->update( $id, $data);
}
更新记录时，需要确定要更新的记录。它应该是由像id这样的主键定义的，或者是由具有不同列的WHEREsql子句定义的。
它应该像下面的一样：
$this->zakatModel->update($id, [
...
]);
// OR
$data = [
...
];
$data['id'] = 4 // for example. You can send with form or you can get from URL.
$this->zekatModel->save($data);
在save方法中，不需要将id值作为单独的参数。因为在方法内部，它会检查自己：
protected function save($data) {
...
$this->update($this->getIdValue($data), $data);
}
快乐编码。。
