select data with condition codeigniter - mysql

Question

i want to show all sparepart
where tb_sparepart.id_jenis = id_jenis and where tb_sparepart.id_merk = id_merk, and than where tb_sparepart.id_merk = 1
id_merk 1 = is mean all merk, but if i try in model is always fail.
i try this model:
function GetById($id_kendaraan){
$this->db->select('*');
$this->db->from('tb_kendaraan');
$this->db->where('tb_kendaraan.id_kendaraan',$id_kendaraan);
$query_kendaraan = $this->db->get();
$hasil = false;
if($query_kendaraan->num_rows() > 0)
{
$data_kendaraan = $query_kendaraan->row();
$hasil = [
'tahun_beli' => $data_kendaraan->tahun_beli,
'id_jenis' => $data_kendaraan->id_jenis,
'id_merk' => $data_kendaraan->id_merk,
'spareparts' => [] // empty array, to be filled with spareparts data
];
$this->db->select('*');
$this->db->from('tb_sparepart');
$this->db->where('tb_sparepart.id_jenis', $data_kendaraan->id_jenis);
$query_sparepart = $this->db->get();
foreach ($query_sparepart->result() as $data_sparepart) {
$spareparts = [
'id_sparepart' => $data_sparepart->id_sparepart,
'sparepart' => $data_sparepart->sparepart,
];
array_push($hasil['spareparts'], $spareparts);
}
}
return $hasil;
}
i try this model and the result is like:
result is show sparepart by id jenis.
but i want to show data sparepart where id merk the car and sparepart where id merk is 1 (all merk).
and i try next model..
my model :
function GetById($id_kendaraan){
$this->db->select('*');
$this->db->from('tb_kendaraan');
$this->db->where('tb_kendaraan.id_kendaraan',$id_kendaraan);
$query_kendaraan = $this->db->get();
$hasil = false;
if($query_kendaraan->num_rows() > 0)
{
$data_kendaraan = $query_kendaraan->row();
$hasil = [
'tahun_beli' => $data_kendaraan->tahun_beli,
'id_jenis' => $data_kendaraan->id_jenis,
'id_merk' => $data_kendaraan->id_merk,
'spareparts' => [] // empty array, to be filled with spareparts data
];
$this->db->select('*');
$this->db->from('tb_sparepart');
$this->db->where('tb_sparepart.id_jenis', $data_kendaraan->id_jenis);
$this->db->where('tb_sparepart.id_merk', $data_kendaraan->id_merk);
$query_sparepart = $this->db->get();
foreach ($query_sparepart->result() as $data_sparepart) {
$spareparts = [
'id_sparepart' => $data_sparepart->id_sparepart,
'sparepart' => $data_sparepart->sparepart,
];
array_push($hasil['spareparts'], $spareparts);
}
}
return $hasil;
}
the picture is show data sparepart where id merk = id merk.
i want to show sparepart in misubishi fuso is:
roda gede sekali (id_merk = 1)
punya mishubisi (id_merk = 14)
oli mesin truck (id_merk = 1)
not with sparepart punya hino, because sparepart punya hino is id_merk = 11.
example:
my tb_kendaraan
|id_kendaraan|id_jenis|id_merk|
| 1 | 1 | 11 |
| 2 | 1 | 14 |
| 3 | 2 | 15 |
my tb_sparepart
|id_sparepart|id_jenis|id_merk|sparepart |
| 1 | 1 | 1 |roda gede sekali |
| 2 | 1 | 14 |punya misubisi |
| 3 | 1 | 1 |oli mesin truck |
| 4 | 1 | 11 |punya hino |
| 5 | 2 | 1 |part motorcyle |
| 6 | 2 | 15 |motorcyle engine |
| 7 | 2 | 16 |motorcyle lamp |
i mean id_merk 1 in tb_sparepart is a all merk.
if i call tb_kendaraan.id_kendaraan = 1
the sparepart must show like be:
roda gede sekali
oli mesin truck
punya hino
and if i call tb_kendaraan.id_kendaraan = 2
the sparepart must show like be:
roda gede sekali
punya misubisi
oli mesin truck
and if i call tb_kendaraan.id_kendaraan = 3
the sparepart must show like be:
part motorcyle
motorcyle engine
thx for help me

Answer 1

Not sure if i understand the question but i think you just need to add the id_merk in your last array. You can then use the field "id_merk" in your checkboxes. Like so:
function GetById($id_kendaraan){
$this->db->select('*');
$this->db->from('tb_kendaraan');
$this->db->where('tb_kendaraan.id_kendaraan',$id_kendaraan);
$query_kendaraan = $this->db->get();
$hasil = false;
if($query_kendaraan->num_rows() > 0)
{
$data_kendaraan = $query_kendaraan->row();
$hasil = [
'tahun_beli' => $data_kendaraan->tahun_beli,
'id_jenis' => $data_kendaraan->id_jenis,
'id_merk' => $data_kendaraan->id_merk,
'spareparts' => [] // empty array, to be filled with spareparts data
];
$this->db->select('*');
$this->db->from('tb_sparepart');
$this->db->where('tb_sparepart.id_jenis', $data_kendaraan->id_jenis);
$query_sparepart = $this->db->get();
foreach ($query_sparepart->result() as $data_sparepart) {
$spareparts = [
'id_sparepart' => $data_sparepart->id_sparepart,
'id_merk' => $data_sparepart->id_merk, // Add id_merk
'sparepart' => $data_sparepart->sparepart,
];
array_push($hasil['spareparts'], $spareparts);
}
}
// To debug; uncomment this
//echo '<pre>'; print_r($hasil); exit();
return $hasil;
}
