提交表单时如何自动将FactoryID和CategoryID插入表格中-Codeigniter

Question

I am using 3 tables for joining. I have a form where i can add a factory. I also can choose a category for that specific factory. i use the following tables:

factorycategories
-----------------
idfactorycategories
idfactories
idcategories
(in this table i use a join to show the categories and factories on one page)

factories
---------
idfactories
factoryname
address
country
telephone
...
...

categories
----------
idcategories
category

I want to insert the last inserted idcategories and idfactories in my factorycategories table. How can i do this?

My model for inserting the form values:

function addbedrijf()
{
    $data1 = array(
       'Bedrijfsnaam' => $this->input->post('Bedrijfsnaam'),
       'Postcode' => $this->input->post('Postcode'),
       'Plaats' => $this->input->post('Plaats'),
       'Telefoonnummer' => $this->input->post('Telefoonnummer'),
       'Email' => $this->input->post('Email'),
       'Website' => $this->input->post('Website'),
       'Profiel' => $this->input->post('Profiel'),
       'Adres' => $this->input->post('Adres'),
       'logo' => $this->input->post('logo')
    );
    $this->db->insert('bedrijven', $data1);
}

My model function for showing categories and factories on the same page:

function get_result($idbedrijven)
{
    $this->db->where('bedrijven.idbedrijven', $idbedrijven);
    $this->db->join('bedrijven', 'bedrijfcategorieen.idbedrijven = bedrijven.idbedrijven');
    $this->db->join('categorieen', 'bedrijfcategorieen.idcategorieen = categorieen.idcategorieen');
    $this->db->group_by('Categorie', 'idbedrijven', 'idcategorieen');
    $result = $this->db->get('bedrijfcategorieen', 1);
    return $result->result(); 
}

Hope i provided enough code for you guys.

Edit:

the code that i have so far using the example below:

function addbedrijf()
{
    $data1 = array(
       'Bedrijfsnaam' => $this->input->post('Bedrijfsnaam'),
       'Postcode' => $this->input->post('Postcode'),
       'Plaats' => $this->input->post('Plaats'),
       'Telefoonnummer' => $this->input->post('Telefoonnummer'),
       'Email' => $this->input->post('Email'),
       'Website' => $this->input->post('Website'),
       'Profiel' => $this->input->post('Profiel'),
       'Adres' => $this->input->post('Adres'),
       'logo' => $this->input->post('logo')
    );
    $this->db->insert('bedrijven',$data1);

    if($this->db->affected_rows() >= 1)
    {
    $this->insert_bedrijfcat($this->db->insert_id);
    }else{
    return FALSE
    }
}

function insert_bedrijfcat($id)
{
    $this->db->insert('bedrijfcategorieen',array('idbedrijven'=>$id));

    return $this->db->affected_rows() ?= 1 ? TRUE : FALSE;
}

Answer 1

You are inserting data to the bedrijven table

and you want to get the last inserted id of

categories and factories table then insert it to factorycategories table also?

THe question is when inserting data to bedrijven table do you insert data to the

categories and factories table ? Because if you do you can use $this->db->insert_id to get the last input id of your categories and factories table, if not you need to query a different sql to get both last input id.

EDIT

here so i modified a some code example

class Some_model Extends CI_Model
{
   public function insert_factory($data)
   {
      $this->db->insert('factory_table',$data);

      //if has affected rows
      if($this->db->affected_rows() >= 1)
      {
        // the insert was successfull send the last insert id to another method
        $this->insert_to_factorycateg($this->db->insert_id);
      }else{
         return FALSE
     }
   }

   //method to insert to factorycateg
   public function insert_to_factorycateg($id)
   {
       //insert 
      $this->db->insert('factorycategories',array('factoryid'=>$id));

      //if affected rows return true else false
      return $this->db->affected_rows() >= 1 ? TRUE : FALSE;
   }
}
