IN THIS ANSWER YOU GET AN ERROR IF YOU CHANGE THE PLAN BUT USING THIS CODE YOU HAVE TO SIMPLY EDIT AND UPDATE IT ANGIN AND THIS MODEL IS CREATE A NEW ID FOR YOUR TASK AND INSERT IT AGAIN.
public function vendorUpdateModel($data)
{
$vendor_id = $this->input->post('vendor_id');
$data = array(
'category_id' => $this->input->post('category_id'),
'plan_id' => $this->input->post('plan_id'),
'city_id' => $this->input->post('city_id'),
'business_name' => $this->input->post('business_name'),
'owner_name' => $this->input->post('owner_name'),
'contact_no1' => $this->input->post('contact_no1'),
'contact_no2' => $this->input->post('contact_no2'),
'vendor_email' => $this->input->post('vendor_email'),
'subscription_date' => $this->input->post('subscription_date'),
'vendor_description' => $this->input->post('vendor_description'),
'vendor_address' => $this->input->post('vendor_address')
);
$this->db->where('vendor_id', $vendor_id);
$this->db->update('vendor',$data);
$this->db->where('vendor_id',$vendor_id);
$this->db->delete('vendor_task_status_mapping');
$this->db->select('task_mapp_id');
$this->db->where('plan_id',$this->input->post('plan_id'));
$query = $this->db->get('plan_task_mapping');
foreach($query->result() as $row)
{
$data2 = array(
'task_mapp_id' => $row->task_mapp_id,
'vendor_id' => $vendor_id,
'task_status' => '0'
);
$this->db->insert('vendor_task_status_mapping', $data2);
}
return;
}

If you added one field in plan_task_mapping table for add unique number then... As you mention your code:
$unique=array();
foreach ($this->input->post('task_id') as $key => $value)
{
$no=rand(0, 15);
$data2 = array(
'unique_no'=>$no,
'plan_id' => $planId,
'task_id' => $value
);
$unique[] = $no; //store no in array to use it.
// echo "Index {$key}'s value is {$value}.";
$this->db->insert('plan_task_mapping', $data2);
}
Before deleting plan_task_mapping table data. fetch that data.
function select()
{
$this->db->where('plan_id',$planId);
$Q = $this->db->get('plan_task_mapping');
if($Q->num_rows() > 0)
{
foreach ($Q->result_array() as $row)
{
$data[] = $row;
}
}
$Q->free_result();
return $data;
}
Then delete the data as you mention in you code:
$this->db->where('plan_id',$planId);
$this->db->delete('plan_task_mapping');
Then delete that old data from VTSM table:
$this->db->where('vendor_plan_task_mapping_id',$data[0]['id']); //this data[0]['id'] come form select(). change field name if required.
$this->db->delete('VTSM');
Here fetch that new inserted data by that unique no: //which we stored it in array.
foreach($unique as $u_no)
{
$this->db->where('unique_no',$u_no);
$Q = $this->db->get('plan_task_mapping');
if($Q->num_rows() > 0)
{
foreach ($Q->result_array() as $row1)
{
$plan[] = $row1;
}
}
$Q->free_result();
return $plan;
}
In above code we have fetched that new inserted data to get their id to insert status.
Now inserting status:
foreach($plan as $a)
{
$Sdata=array(
"plan_task_mapping_id"=>$a['id'], //this is new id change name if required
"status"="your new status");
$this->db->insert('VTSM',$Sdata);
}

Use $this->db->insert_batch(); instead of inserting in foreach loop.
Check at this link how to use it.
