Inserting multiple rows in database codeigniter - php

Question

I have some issue about the inserting data. It will insert only the waybillno data but the quantity is always same. Please check my code - I think the model is wrong.
Controller
public function create_cargo_manifest(){
$core_model = new Core_m;
$core_model->save_cargo_details($this->input->post());
redirect('core/cargo_lookup/');
}
Model
function save_cargo_details(){
$quantity = $this->input->post('quantity');
$waybilldate = $this->input->post('waybilldate');
$data = array();
foreach($this->input->post('sys_wbdetails') as $sys_wbdetails) {
$data[] = array(
'waybillno' => $sys_wbdetails,
'quantity' => $quantity,
'waybilldate' => $waybilldate,
);
}
return $this->db->insert_batch('sys_cargodetails', $data);
}
View
<?php foreach($waybill_header as $waybill_header) { ?>
<?php echo form_open('core/create_cargo_manifest'); ?>
<td><input type="checkbox" name="sys_wbdetails[]" value="<?php echo $waybill_header->waybillno; ?>"></td>
<td><?php echo $waybill_header->waybillno; ?></td>
<td><?php echo $waybill_header->waybilldate; ?><input type="hidden" value="<?php echo $waybill_header->waybilldate; ?>" name="waybilldate"></td>
<td><input type="text" size="5" value="<?php echo $waybill_header->quantity; ?>" name="quantity"></td>
<td><input type="submit" value="save"></td>
<?php } ?>
<?php form_close(); ?>

Answer 1

All your inputs for quantity have the same name : quantity. So you're only submitting the last value in your form. You need to use an array for those inputs (quantity[]), just like for your checkboxes. And you might want to do the same for the waybilldate inputs.
<td><input type="text" size="5" value="<?php echo $waybill_header->quantity; ?>" name="quantity[]"></td>
And then in PHP, something like that :
$data = array();
// Count distinct entries in the form
$count = count($this->input->post['sys_wbdetails']);
for($i=0; $i < $count; $i++) {
$data[] = array(
'waybillno' => $this->input->post['sys_wbdetails'][$i],
'quantity' => $this->input->post['quantity'][$i],
'waybilldate' => $this->input->post['waybilldate'][$i],
);
}
EDIT : also, take a look at this answer if you want a clean way to keep track of which form input goes where.
