Question

I have a Model.class.php and a Bag.class.php, the Bag class extends the Model class.

But when i try to call a function defined in Bag.class.php, it show a fatal error ” Call to undefined function fill_entity() in”

bag.class.php :

class Bag extends Model{
 public function __construct($table_name){
    $this->table_name = $table_name;
 }

 public function fill_entity($row){
     $this->id = $row['bagID'];
     $this->name = $row['bagName'];
     $this->price = $row['bagPrice'];
     $this->url = $row['bagURL'];
     $this->img_url = $row['bagImgURL'];
     $this->mall_id = $row['mallID'];
     $this->brand_id = $row['brandID'];
 }

here’s my php page where i call this function :

$bag = new Bag($bagtype);
$bag.fill_entity($row);  <---- error on this line.

You’re using the wrong syntax. PHP doesn’t use dot notation, but rather -> (arrow/pointer notation)

Try using this:

$bag->fill_entity($row);

(The . is still used in PHP, but is used for string concatenation.)

Don’t feel bad about missing this, I did it plenty of times when I first tackled PHP.
