this is my view
<table id="box-table-a" summary="Employee Pay Sheet">
<thead>
<tr>
<th scope="col">Description</th>
<th scope="col">Price</th>
<th class="centered" scope="col">Options</th>
</tr>
</thead>
<tbody>
<?php foreach ($foto_produk->result() as $key => $value) {?>
<tr>
<td><?php echo $value->description;?></td>
<td><?php echo $value->price;?></td>
<td class="centered"><input type="checkbox" name="produk_foto[]" value="<?php echo $value->id;?>" /></td>
</tr>
<?php }?>
</tbody>
</table>
here's my controller code
if($this->input->post('produk_foto')){
$id_foto = $this->input->post('produk_foto');
foreach ($id_foto as $key => $value) {
$this->db->where('id', $value);
$query = $this->db->get('foto_product');
if($query->num_rows() > 0){
foreach($query->result() as $ids => $rows){
echo $rows->id.'<br />';
$data_produk = array(
'user_data'=> array(
'id' => $rows->id,
'price' => $rows->price,
'name' => $rows->description,
'qty' => $rows->aantal
)
);
$this->cart->insert($data_produk);
}
}
}
}
