How to add Array to database in codeigniter? - php

Question

I have a form with a multiselect field. I choose 3 categories for each company, but only one is added to the database.
How can I add an Array of 3 categories to my database? I use a joined table to add multiple categories to a company.
My table structure:
companies
---------
companyid
companyname
etc etc
categories
---------
categoryid
categoryname
companycategories
----------------
companycategoryid
categoryid
companyid
My controller:
function update()
{
$id = $this->uri->segment(3);
$data = 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' => $this->input->post('Adres'),
);
if($this->input->post('logo')) { $data['logo'] = $this->input->post('logo'); }
$this->members_model->updatebedrijf($id, $data);
$b = $this->session->userdata('idbedrijven');
redirect("members/$b");
}
My model:
function updatebedrijf($id, $data)
{
$this->db->where('idbedrijven', $id);
$this->db->update('bedrijven', $data);
$to_bedrijfcategorieen2['idcategorieen'] = $this->input->post('categorieen');
$this->insert_bedrijfcat1($to_bedrijfcategorieen2);
}
function insert_bedrijfcat1($data1)
{
echo '<pre>';
print_r($data1);
echo '</pre>';
$id = $this->uri->segment(3);
$this->db->where('idbedrijven', $id);
$this->db->update('bedrijfcategorieen', $data1);
return $this->db->affected_rows() >= 1 ? TRUE : FALSE;
}
My form:
<tr>
<td><?= form_label('Categorieen'); ?></td>
<td><?= form_multiselect('categorieen[]', $opties, key($selectie)); ?></td>
</tr>
The output of print_r($data1); gives me this:
Array
(
[idcategorieen] => Array
(
[0] => 11
[1] => 12
[2] => 13
)
)
Hope it is clear.

To Update one to many relation here is the technique
function insert_bedrijfcat1($data1)
{
$delete = $this->db->query("DELETE FROM `bedrijfcategorieen` WHERE `idbedrijven` = '" . $id. "'");
$id = $this->uri->segment(3);
foreach($data1['idcategorieen'] as $cat_id){
$this->db->query("INSERT INTO `bedrijfcategorieen` (`idbedrijven`,`idcategorieen` ) VALUES ('".$id."','".$cat_id."')");
}
}
