我有一个程序可以使用批处理过程存储一些财务价值。主表是finance_budget和finance_budget_issue。 finance_budget.budget_id = finance_budget_issue.budget_id（1对多加入）
我尝试使用以下代码编辑一些记录
控制者
public function editIssues($id)
{
$this->checkPermissions('edit', 'allocationIssues');
$bc = array(array('link' => 'budget/regIssues', 'page' => 'Allocation Issues'), array('link' => '#', 'page' => 'Edit'));
$meta = array('page_title' => 'Allocation Issues', 'bc' => $bc);
$this->form_validation->set_rules('vote_id', 'Vote', 'required');
$this->form_validation->set_rules('budget_date', 'Budget Date', 'required');
if ($this->form_validation->run() == true) {
$ustock = array(
'vote_id' => $this->input->post('vote_id'),
'budget_date' => $this->input->post('budget_date'),
'ref_no' => $this->input->post('ref_no'),
'usr' => $this->session->userdata('id_user'),
'added_time' => date('Y-m-d h:i:s'),
'budget_status' => 'issues',
'transfer_status' => 'Pending'
);
$count = count($this->input->post('office'));
$offices = $this->input->post('office');
$amount = $this->input->post('amount');
$notes = $this->input->post('notes');
for ($x = 0; $x < $count; $x++) {
$details[$x]['budget_id'] = $id;
$details[$x]['office'] = $offices[$x];
$details[$x]['amount'] = $amount[$x];
$details[$x]['notes'] = $notes[$x];
}
}
if ($this->form_validation->run() == true && $this->Budget_model->editIssuedAllocations($ustock, $details, $id)) {
$this->session->set_flashdata('message', 'Successfully Updated ..!!');
redirect('budget/regIssues');
} else {
$this->data['vote'] = $this->Budget_model->getVote(array('office_id'=>$this->session->userdata('office_id')));
$this->data['office'] = $this->Budget_model->getOffice();
$this->data['issues'] = $this->Budget_model->budgetById($id);
$this->render('budget/editIssues', $meta, $this->data);
}
}
模型
function editIssuedAllocations($ustock,$details,$id)
{
if(!empty($id)){
$this->db->trans_start();
$this->db->update('finance_budget',$ustock,array('budget_id'=>$id));
if($id!=1){
$this->db->where('budget_id', $id);
$this->db->delete('finance_budget_issue');
$this->db->insert_batch('finance_budget_issue', $details);
}
$this->db->trans_complete();
return $this->db->trans_status();
}
return false;
}

期望的输出
应该在与相同的budget_id相关的Finance_budget和finance_budget_issue表中编辑一些值（例如：-budget_id = 2995）
错误
在我的视图中编辑了一些有效且正确保存的值之后。当我在视图中按下保存按钮而不编辑任何值时，finance_budget_issue表中与budget_id相关的finance_budget表相关的记录将被删除。
我不明白我要怎么做？谁能帮我 ？
最佳答案
您可以修改模型以检查$details是否为空或不保留finance_budget_issue表：
function editIssuedAllocations($ustock,$details,$id)
{
if(!empty($id)){
$this->db->trans_start();
$this->db->update('finance_budget',$ustock,array('budget_id'=>$id));
if($id!=1 && !empty($details[0])){
$this->db->where('budget_id', $id);
$this->db->delete('finance_budget_issue');
$this->db->insert_batch('finance_budget_issue', $details);
}
$this->db->trans_complete();
return $this->db->trans_status();
}
return false;
}
