Display an array data from two tables in codeigniter - php

Question

I've two tables on my database, monitor [pk = idMonitor] and monitor_data [pk = idMonitor_data].
Please click you can see the tables fields here. As you can see i put the array data in table monitor_data.
I want to Update the condition for every idinventory where monitor_data.idMonitor = $id.
But first i want to display the current data of 'monitordate','idinventory', and 'condition' from database to my view.
My controller
public function edit($id=0) {
$dataa = $this->monitor_m->get_record(array('monitor_data.idMonitor'=>$id),true);
$this->data->monitordate = $dataa->monitordate;
$this->data->condition = $dataa->condition; <-line 20
$this->data->detail = $this->monitor_m->get_record(array('monitor_data.idMonitor'=>$id),true);
$this->template->set_title('SMIB | Monitoring')
->render('monitor_edit',$this->data);
}
My View (monitor_edit)
<?php echo form_open(site_url("monitor/ubah"),'data-ajax="false"'); ?>
<?php foreach ($detail as $items): ?>
<h4><?php echo '[ '.$items['idinventory'].' ] '?> </h4>
<?php echo form_label ('Condition : ');
echo form_dropdown('condition', array('good'=>'Good','broke'=>'Broken','lost'=>'Lost'),#$items['condition']);
?>
<?php endforeach; ?>
<?php echo form_close(); ?>
My Model
class Monitor_m extends MY_Model {
public function __construct(){
parent::__construct();
parent::set_table('monitor','idMonitor');
}
public function get_record($id = 0,$get_user = FALSE) {
$this->db->where($id);
if ($get_user){
$this->db->join('monitor_data','monitor_data.idMonitor = monitor.idMonitor');
$this->db->join('inventory','inventory.idinventory = monitor_data.idinventory');
$this->db->join('user','user.id_user = monitor.id_user');
}
$data = parent::get_array();
return $this->improve_data($data);
}
Here is my problem : its work fine for monitordate code in my controller, BUT i keep getting an error for condition code
Maybe because i use 'monitor_data.idMonitor' as my parameter $id not idinventory. how can i use 2 parameters for example like where idMonitor=$id and idinventory=$idiventory.
Do i explain it right ?
Severity: Notice Message: Trying to get property of non-object
Filename: controllers/monitor.php Line Number: 20
Please Please help me, i dont know what is wrong with my controller :( i've searching the solution but none of those work. :(

Answer 1

It's weird if you can get monitordate but can't get condition.
Can you edit your controller to be like this?
public function get_record($id = 0,$get_user = FALSE) {
$this->db->where($id);
if ($get_user){
$this->db->join('monitor_data','monitor_data.idMonitor = monitor.idMonitor');
$this->db->join('inventory','inventory.idinventory = monitor_data.idinventory');
$this->db->join('user','user.id_user = monitor.id_user');
}
// $data = parent::get_array();
$data = $this->db->result_array();
print_r($data);
echo $this->db->last_query();
exit;
return $this->improve_data($data);
}
