Custom Result Objects & Setter - Fabien72 - 11-03-2023
Hi, I started to use CI4 three days ago and today I'm facing a problem with "Custom Result Objects". Here is the class of my custom object :
PHP Code:
class Transaction
{
protected int $id;
protected string $name;
protected float $amount;
public function __get($key)
{
if (property_exists($this, $key)) {
return $this->{$key};
}
}
public function __set($key, $value)
{
if (property_exists($this, $key)) {
$this->{$key} = $value;
}
}
}
The problem is when I'm using the function "getCustomResultObject" the "__set" method is never called, attributes are directly updated. Indeed, I tried to modify the setter to update my attributes using the $key & $value variables to do some operations, but the setter is never called. That is strange because I saw in the documentation :
Quote:The object will have all values returned from the database set as properties. If these have been declared and are non-public then you should provide a __set() method to allow them to be set.
And indeed if I remove the "__set" method, I get a error message "Cannot access protected property App\Entities\Transaction::$name". So the __set method is necessary to update the "protected" attributes, but the method is never used. So is it a bug, or I missed something ?
Thanks for your help.

Why do you think __set() is not called?
RE: Custom Result Objects & Setter - ozornick - 11-03-2023
If you have "protected $name" properties declared, they are automatically filled with values.
When there is no property, __set() is executed. BUT, you re-check the declaration of the property (they are already filled in). property_exists() is unnecessary.
PHP Code:
// Class
class Notify {
protected $id, $user_id, $title, $is_read;
public function __set($name, $value)
{
$this->{$name} = $value;
return $this;
}
}
// Select result
$notify = $model->builder()->limit(1)->get()->getCustomResultObject(Notify::class);
// Output
array:1 [▼
0 => App\Controllers\Notify {#199 ▼
#id: "5"
#user_id: "1"
#title: "New Message"
#is_read: "yes"
+"body": "New post created!"
+"created_at": "2023-11-01 20:18:43"
}
]

What do you mean by automatically? How?

See https://www.php.net/manual/en/mysqli-result.fetch-object.php
Mysqli creates an object a little differently. As Reflection?
Props id, user_id, title, is_read not calling __set(). body, created_at run __set(). What did I say wrong?
PHP Code:
// Setter
public function __set($name, $value)
{
echo $name . PHP_EOL;
$this->{$name} = $value;
return $this;
}
// Contains row: id, user_id, title, is_read, body, created_at
$notify = model(NotificationModel::class)->builder()->limit(1)->get()->getCustomResultObject(Notify::class);
// Output
body created_at
array:1 [▼
0 => App\Controllers\Notify {#199 ▼
#id: "5"
#user_id: "1"
#title: "New Message"
#is_read: "yes"
+"body": "New post created!"
+"created_at": "2023-11-01 20:18:43"
}
]
