I try a code like example:https://docs.phalcon.io/zh/latest/reference/models.html#setters-getters-public-properties-vs-setters-getters
class Robots extends \Phalcon\Mvc\Model
{
protected $id;
public function getId(){
return 2;
}}
but it does't worker
$robot = Robots::findById(1);
echo $robot->id; // it's 1
my phalcon version is 1.3.4
Not problem with Phalcon, in your example, you'll need $robot->getId()
protected $id;
public function __get($name)
{
if (method_exists($this, $name)) {
return $this->$name;
}
}
// This can be accessed with $robot->id;so, the phalcon doesn't implement those actions using it's get getId() or setId()?
like: i have a
public function setId($id){
return $this->id = 2;
}then
$robot = new Rebots();
$robot->id = 1;
$robot->save();the id column in db is still 1?
Nope, Phalcon doesn't create the accessors for you, $robot->id = 2 is not same as $robot->setId(2), this is really related PHP OO and not Phalcon.
if you have public function setId($id) { ... } for protected property (class variable), you then have to set that property like $robot->setId(2).
In the Phalcon examples, public class variables is used, or you can use protected class variables with magic method accessors. See __get() and __set() here : https://php.net/manual/en/language.oop5.magic.php
Here is my set magic method.
/*
* Checks if property exists
* Changes $this->camelCase to $this->camel_case, due to my DB naming convention
* omited this on my __get example above
*/
public function __set($name, $value)
{
if (!property_exists($this, $name)) {
$name = preg_replace_callback('/[A-Z]/', function($matches) {
return '_' . strtolower($matches[0]);
}, $name);
}
$this->$name = $value;
}well, thx
