Question

我有数据库服务器中已经存在的数据，我想根据id表进行更改。我想一次更新，以便3个数据表也更新，因为表ID也在另一个表中。我尝试过，但不能。请帮助我

我已经从几张桌子中加入了。我还搜索了：link！：link！

这是我的控制器

public function updateservicenew(){
$id= $this->uri->segment(3);
$data['vendor']= $this->model_vendor->show_data_all();
$data['vendor2']= $this->model_vendor->show_data_vendor2();
$data['service']= $this->Madmin2->getservicenew($id)->row_array();
$this->template->viewadmin2('admin2/transaks/updateservicenew',$data);
}
public function saveservicenew(){
$this->Madmin2->saveservicenew($this->input->post());
redirect(base_url('admin2/transaksidone'));
}

这是我的模型

public function getservicenew($id){     $this->db->select('kontak_sis.*,vendor.*,vendor2.*,service_sis.*,sumber_info.*,provinsi.*,kota.*,mst_service.*,service.*');
$this->db->from('service_sis');
$this->db->join('vendor', 'service_sis.id_vendor=vendor.id_vendor', 'left');
$this->db->join('vendor2', 'service_sis.id_vendor2=vendor2.id_vendor2', 'left');
$this->db->join('mst_service', 'service_sis.id_mst_service=mst_service.id_mst_service', 'left');
$this->db->join('kontak_sis', 'service_sis.id_kontak=kontak_sis.id_kontak', 'left');
$this->db->join('sumber_info', 'service_sis.id_sumber=sumber_info.id_sumber', 'left');
$this->db->join('provinsi', 'service_sis.id_provinsi=provinsi.id_provinsi', 'left');
$this->db->join('kota', 'service_sis.id_kota=kota.id_kota', 'left');
$this->db->join('service', 'service_sis.id_service=service.id_service', 'left');
$param = array('service_sis.id_service'=>$id);
return $this->db->get_where('',$param);
}
public function simpanservicenew(){
$data_pelanggan['cid']= $this->input->post('cid');
$data_pelanggan['nama_perusahaan']= $this->input->post('nama_perusahaan');
$data_pelanggan['destination']= $this->input->post('destination');
$data_pelanggan['alamat_perusahaan']= $this->input->post('alamat_perusahaan');
$data_pelanggan['pic_perusahaan']= $this->input->post('pic_perusahaan');
$data_pelanggan['telepon_pic']= $this->input->post('telepon_pic');
$data_pelanggan['fax']= $this->input->post('fax');
$data_pelanggan['hp']= $this->input->post('hp');
$data_pelanggan['email_pic']= $this->input->post('email_pic');

$this->db->where('id_kontak',$this->input->post('id_kontak'));
$this->db->update('kontak_sis',$data_pelanggan);

$data_vendor['pic_vendor']= $this->input->post('pic_vendor');
$data_vendor['media_vendor']= $this->input->post('media_vendor');
$data_vendor['kapasitas_vendor']= $this->input->post('kapasitas_vendor');
$data_vendor['telepon_vendor']= $this->input->post('telepon_vendor');
$data_vendor['email_vendor']= $this->input->post('email_vendor');

$this->db->where('id_vendor',$this->input->post('id_vendor'));
$this->db->update('vendor',$data_vendor);

$data_vendor2['pic_vendor2']= $this->input->post('pic_vendor2');
$data_vendor2['media_vendor2']= $this->input->post('media_vendor2');
$data_vendor2['kapasitas_vendor2']= $this->input->post('kapasitas_vendor2');
$data_vendor2['telepon_vendor2']= $this->input->post('telepon_vendor2');
$data_vendor2['email_vendor2']= $this->input->post('email_vendor2');

$this->db->where('id_vendor2',$this->input->post('id_vendor2'));
$this->db->update('vendor2',$data_vendor2);

我想一次更新，以便3个数据表也更新，因为表ID也位于另一个表中。谢谢您的帮助

Answer 1

我从您的代码中了解到，您想使用单个查询更新3个表。在这种情况下，您可以使用以下代码。

$this->db->set('a.cid', $this->input->post('cid'));
$this->db->set('a.nama_perusahaan',  $this->input->post('nama_perusahaan'));

$this->db->set('b.pic_vendor', $this->input->post('pic_vendor'));
$this->db->set('b.media_vendor', $this->input->post('media_vendor'));

$this->db->set('c.pic_vendor2', $this->input->post('pic_vendor2'));
$this->db->set('c.companyaddress', $this->input->post('pic_vendor2'));

$this->db->where('a.id', 1);
$this->db->where('a.id = b.id');
$this->db->where('a.id = c.id');
$this->db->update('table as a, table2 as b',table3 as c);

但是您应该以更专业的方式使用Codeigniter Transactions。如果任何查询失败，则另一个查询将回滚。

    $this->db->trans_start();
    $this->db->query('AN SQL QUERY...');
    $this->db->query('ANOTHER QUERY...');
    $this->db->query('AND YET ANOTHER QUERY...');
    $this->db->trans_complete();

如何在Codeigniter中按ID更新3个表的现有数据
