php-relations error

General
1

I made a simple PHP app based on this example in the docs:

https://backendless.com/documentation/data/php/data_relations_save_update.htm

I did the exact same thing in my code yet I’m still getting this error:

"Uncaught
exception ‘backendless\exception\BackendlessException’ with message
‘Backendless API return error: Missing ___class property for entity:
__relations Error code:1020’ .
class Cinema {

public $Name;

public $Phone;
public $Location;

public $__relations = [
‘Location’ => ‘LO’
];

 public function getName() {
    return $this->Name;
}

public function setName( $Name ) {
    $this->Name = $Name;
}

public function getPhone() {
return $this->Phone;
}

public function setPhone( $Phone ) {
$this->Phone = $Phone;
}

public function getLocation() {
    return $this->Location;
}

public function setLocation($Location) {
    $this->Location = $Location;
}

}
THis is my code.CAnt see problem need help with error.

you can not have such properties in your class

public $__relations = [
'Location' => 'LO'
];

you can have ralations only for some objects. Try to use the exact example from document

3

In the example ‘Location’ is the field in my table and LO is the php file wich contains the class of relational table same as the case in of

public $__relations = [
‘address’ => ‘test\models\Address’
];
I cant understand what you mean by ‘use the exact from document’.

4

you should write something like this

public $__relations = [ new Location()];
5

For that i m getting unexpected ‘new’.

6

Did you meant that for php?

7

I meant php.

use this code


class Location {
    public $test;
}        


class Cinema {


public $Name;


public $Phone;


public $Location;


public $__relations;
}


$cinema = new Cinema;
$location = new Location();
$cinema->$__relations = [$location];

Thanks for the help but it is not working man ,firstly the code is not working if $__relations is defined after the end of Cinema class and if it is put inside it gives error as unexpected ‘$cinema’ expecting a function.

9

why do you define $__relations field? do you have such column in your table ?

10

i meant

$cinema = new Cinema;
$location = new Location();
$cinema->$__relations = [$location];
These three lines

If i write them outside Cinema class it shows error about undefined variable $__relations and if inside cinema class it shows $cinema not expected, a function is expected.
