OLD UPDATE
I am trying to manually insert value in a array if My db is resulting 0 results.
I am trying to create a manually a array which stores value as this model function stores
public function fetch_LifeStyeActivity_byid($activityDate, $uid) {
----
----
$query = $this->db->order_by('calorie_activity.ordering', 'ASC')->get_where('calorie_activity', array('creater_id' => $uid,'activity_date' => $activityDate, 'parent_id =' => '625'));
$data = array();
if ($query->num_rows() > 0) {
foreach ($query->result() as $row) {
$data[] = $row;
}
return $data;
}
return false;
}
I am creating it like this from my controller like this
$data["lifeStyle_activity_query"] = array(
"cals" => "6"
);
$this->load->view('weight_lose/activities', $data);
& in view page while retrieving i am getting exception
foreach ($lifeStyle_activity_query as $row) {
echo $row->cals;
}
Exception getting as:
A PHP Error was encountered
Severity: Notice
Message: Trying to get property of non-object
Note: I only need help on modifying controller logic(please do not tell to change the view page code)

Answer 1

Your error simply comes from the fact that you've an array and try to use it as an object. You could just cast your array into an object so it can be used as such in your view.
$data["lifeStyle_activity_query"] = array(
"cals" => "6"
);
$data["lifeStyle_activity_query"] = (object) $data["lifeStyle_activity_query"];
echo $data["lifeStyle_activity_query"]->cals; // -> 6
Edit for your update :
$val['cals'] = '1545.616024';
$arr[0] = (object) $val;
