How to Update Two table Data one after other In codeigniter?

Question

how to update plan with vendor_plan_task_status_mapp table.

the model for plan update is

public function updatePlanData(){

    $planId = $this->input->post('plan_id');
    $data = array(

                    'plan_title' => $this->input->post('plan_title'),
                    'plan_price' => $this->input->post('plan_price'),
                    'plan_desc'     => $this->input->post('plan_desc')

                );

    $this->db->where('plan_id', $planId);
    $this->db->update('tbl_plan', $data);


    $this->db->where('plan_id',$planId);
    $this->db->delete('plan_task_mapping');



    foreach ($this->input->post('task_id') as $key => $value)

     {
        $data2 = array(

        'plan_id' => $planId,
        'task_id'   => $value

        );
     // echo "Index {$key}'s value is {$value}.";
           $this->db->insert('plan_task_mapping', $data2);
     }

//-------- HEAR I NEED A CODE TO UPDATE The V_T_S_M table-----------

}

after 1st table update i want to update the data in vendr_task_status_mapping table?????

Answer 1

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

Answer 2

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;
         }

Answer 3

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);

}
