MySQL Update Batch Process Remove Some Records - mysql

Question

I have a program to store some financial values using batch process. Main tables are finance_budget & finance_budget_issue. finance_budget.budget_id = finance_budget_issue.budget_id (1 to many join)
I tried to edit some records using following code
Controller
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, $this->data);
}
}
Model
function editIssuedAllocations($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;
}

Desired Output
Should be edit some values in the finance_budget & finance_budget_issue tables that related with same budget_id (Eg:- budget_id =2995)
Error
After editing some values in my view that is working & save properly. When I press the save button in my view without editing any value, the record in finance_budget_issue table that is related to finance_budget table by budget_id is deleted.
I can not understand what I am going wrong ? Can anyone help me ?

Answer 1

You could modify the model to check whether $details are empty or not to leave the finance_budget_issue table intact :
function editIssuedAllocations($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;
}

Answer 2

I have modified the for loop as follows in the controller.
$count = count($this->input->post('office'));
$offices = $this->input->post('office');
$votes = $this->input->post('vote_id');
$amount = $this->input->post('amount');
$notes = $this->input->post('notes');
$bdate = $this->input->post('budget_date');
for ($x = 0; $x < $count; $x++) {
$details[$x]['budget_id'] = $id;
$details[$x]['office'] = $offices[$x];
$details[$x]['vote_id'] = $votes[$x];
$details[$x]['amount'] = (-1)*$amount[$x];
$details[$x]['notes'] = $notes[$x];
$details[$x]['budget_date'] = $bdate[$x];
$details[$x]['status'] = 1;
}
Now the issue was fixed partially. But the saving vote_id of finance_budget_issue table is incorrect without editing.
