abstract class BaseModel {
public function find($params){
$table = $this->$table;
//...
}
}
class User extends BaseModel {
protected $table = "users";
}
If I do:
$u = new User();
$u->find([]);
It works just because I created a new instance of the user class. but if I want to do it directly:
User::find([]);
I do not get why not to any reference to $this
How do I resolve this?
You can solve this by simply keeping it as you already do
$u = new User();
$u->find([]);
$this can not be statically accessed. So it will not work to User::find([]);
You can do what you want, but not recommended.
If the purpose is merely visual, to have a smaller code, forget it. Or if you want to provide inline access, you can think of something else as method chaining or simply create a function:
function userFinD()
{
$u = new User();
return $u->find([]);
}
userFinD();
But if you get annoyed at having to create a function, you can also invoke inline a multi-line routine. For this you use anonymous functions .
As I'm not sure what you're really going to do, I'll avoid detailing the options above.
SOLUTION:
abstract class BaseModel {
public function find($params){
$table = '';
if($this)
$table = $this->$table;
else {
$u = new User();
$table = $u->table;
unset($u);
}
//...
}
}
class User extends BaseModel {
protected $table = "users";
}
