Update data in codeigniter 4 using update() or save() - Does not work because of a missing ID - codeigniter-4

Question

I tried to update my database by using update(), but I don't have an id in it. Instead, I have a primary key named kwt.
Every time I try to execute update(), the query always refers to table.id instead of 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:
I need to make WHERE 'zakat'.'id' become WHERE 'zakat'.'kwt'
This is my controller:
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('/');
}

For my model, I didn't write anything yet because there is nothing written in my tutorial's model. When I use save() instead of update() it will create new data with the same primary key.

Answer 1

its need id of table to update data;
your are forgot id
look at my sample example
function dommy($id, $data){
$myModel = new MyModel();
$myModel->update( $id, $data);
}

Answer 2

When you update a record, you need to identify which record(s) you want to update. It should be a definition by a primary key like id or a definition by WHERE sql clauses with different columns.
It should be like on of the following:
$this->zakatModel->update($id, [
...
]);
// OR
$data = [
...
];
$data['id'] = 4 // for example. You can send with form or you can get from URL.
$this->zekatModel->save($data);
In save method, no need to put id value as a separate parameter. Because inside the method, it checks itself:
protected function save($data) {
...
$this->update($this->getIdValue($data), $data);
}
Happy coding..
