Code Ignitor - Trying to get property of a non object

I am trying to implement cart functionality in codeignitor. In my controller I have a public function add and in my model a public function called get to fetch data from database according to the product selected.

add

get

here is my Controller

public function add() {
$id = $this->input->post('id');
$product = $this->products_model->get($id);

echo "<pre>";
print_r($product); die();

$data = array(
'id' => $id,
'name' => $product->pro_name,
'qty' => 1,
'price' => $product->pro_price
);
$this->cart->insert($data);
}


and here is my Model

public function get($id) {
$results = $this->db->get_where('products', array('pro_id' => $id));
return $results->result_array();
}


When I print_r($product) I get an array like this.

print_r($product)

Array
(
[0] => Array
(
[pro_id] => 1
[pro_name] => Beef Carrot & Pea Food
[pro_price] => 150.00
[pro_image] => 1.png
)

)


But when I try to insert in the data array I get this error.

A PHP Error was encountered

Hope this will help you :

Since u r using single item with object in your controller,So you should use row() instead of result_array();

row()

result_array()

Your model should be like this :

public function get($id)
{
$results = $this->db->get_where('products', array('pro_id' => $id));
return $results->row();
}


Your controller should be like this :

Print $data in your controller to check it has data;

$data

public function add()
{
$id = $this->input->post('id');
$product = $this->products_model->get($id);

$data = array(
'id' => $id,
'name' => $product->pro_name,
'qty' => 1,
'price' => $product->pro_price
);
print_r($data); die();
$this->cart->insert($data);
}

You need to access values using array syntax not object syntax

$product->pro_name instead of this use $product['pro_name']

$product->pro_name

$product['pro_name']

You are returning an array and not an object. Hence, $product will contain an array...

$product

As the error says:

Trying to get property of non-object

Trying to get property of non-object

Try this:

$data = [
'id' => $id,
'name' => $product[0]['pro_name'],
'qty' => 1,
'price' => $product[0]['pro_price']
];


...or better yet, use row() method on your model's get() method, like so:

row()

get()

public function get($id)
{
$results = $this->db->get_where('products', [
'pro_id' => $id
]);

return $results->row();
}


Using that, you can now have:

$data = [
'id' => $id,
'name' => $product->pro_name,
'qty' => 1,
'price' => $product->ipro_price
];
