How to post multiple inputs in database - forms

Question

I'm working with Codeigniter, on a sales targets' form for salesmen.
They have to input values for each product, locality, year, etc.
Product and locality are already get with existing database: no need to set rules (see controller).
When I checked the post (with enable_profiler of Codeigniter), I get this:
The problem is these datas don't insert into the database table.
I read and tested a lot, but always blocked.
Here is my model:
public function add($params)
{
$this->db->insert($this->table, $params);
return $this->db->insert_id();
}
My controller:
$this->load->library('form_validation');
$this->form_validation->set_rules('year', 'Year', 'required|integer');
$this->form_validation->set_rules('prevision', 'Prevision', 'required');
$this->form_validation->set_rules('value', 'Value', 'required|integer');
if ($this->form_validation->run()) {
$params = array(
'year' => $this->input->post('year'),
'prevision' => $this->input->post('prevision'),
'locality_id' => $this->input->post('locality'),
'product' => $this->input->post('product'),
'value' => $this->input->post('value'),
);
$this->Objectif_model->add($params);
redirect('admin/objectif');
} else {
$this->layout('admin/objectif/add');
}
And my view with inputs:
<?php foreach ($products as $product) : ?>
<tr class="form-group">
<td class="bg-warning">
<?= $product->grp_product; ?>
</td>
<td class="bg-warning product">
<?= $product->code; ?>
</td>
<?php foreach ($localities as $locality ) : ?>
<td>
<input type="text" class="form-control valeur" placeholder="Value k€" name="value[]" data-validation="number" data-validation-ignore="./" data-validation-optional="true" />
<input type="text" name="year[]" />
<input type="text" name="prevision[]" />
<input type="text" name="product[]" value="<?= $product->code ?>" />
<input type="text" name="localite_id[]" value="<?= $locality->id ?>" />
</td>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
Hope you will help me.

I find my answer.
In my controller, I had to pass each post in a variable and made a loop.
//action post in a var for each data
$id = $this->input->post('id');
$prev = $this->input->post('prevision');
$year= $this->input->post('year');
$locality_id = $this->input->post('locality_id');
$product = $this->input->post('product');
$value= $this->input->post('value');
if ($this->form_validation->run()) {
$count_id = count($id);
if (isset($id)) {
for ($i = 0; $i < $count_id; $i++) {
$obj[$i] = array(
'id' => $id[$i],
'prevision' => $prev,
'year' => $year,
'locality_id' => $locality_id[$i],
'product' => $product[$i],
'value' => $value[$i]*1000
);
} // endfor
if (isset($obj)) {
$this->Objectif_model->add_obj($obj);
} // endif
}// endif isset
}// endif form validation
