How can fix error Message: Invalid argument supplied for foreach() - Line Number: 28 in following foreach ?
<?php
$mileage = array();
$mileage_input = $this->input->post('mileage');
foreach ($mileage_input as $idx => $name) { //Line 28
$mileage[] = array(
'mileage' => $mileage_input[$idx]
);
}
$data = array(
'mileage' => json_encode($mileage),
'customer_number' => $customer_number,
'name' => $this->input->post('name')
);
$this->db->insert('customer', $data);
?>
$mileage_inputis probably not an array, which is why it isn’t working.
