How to get data from array in object

Question

I can't seem to get specific data from an array inside an object.

$this->fields->adres gets the address correctly, but i can't get a level deeper.

I've tried:

$this->fields->province
$this->fields->province->0
$this->fields->province[0]

And: (edit)

$this->fields["province"][0]
$this->fields['province'][0]
$this->data->fields['province'][0]

But it does not return anything while it should return "Flevoland".

First part of the object print_r($this, TRUE) below:

RSMembershipModelSubscribe Object
(
    [_id] => 2
    [_extras] => Array
        (
        )

    [_data] => stdClass Object
        (
            [username] => testzz
            [name] => testzz
            [email] => [email protected]
            [fields] => Array
                (
                    [province] => Array
                        (
                            [0] => Flevoland
                        )

                    [plaats] => tesdt
                    [adres] => test

Solution 1

As you can see by your output, object members are likely to be private (if you follow conventions, anyway you must prepend an underscore while calling them), so you're calling them the wrong way; This code works:

$this->_data->fields['province'][0];

You can see it in action here; I created a similar object, and using

$membership = new RSMembershipModelSubscribe();
echo $membership->_data->fields['province'][0];

outputs "Flevoland" as expected.

Solution 2

You can also use type casting.

$fields = (array) $this->data->fields;
echo $fields['province'][0];

be consistent in language. Use 'city' and 'address' ;)

[Rene Pot]

unfortunately not. Fields is an array

You were almost there, @Antoon :). Please consider marking this answer as "accepted" (the tick mark under the vote count) for future references; glad to have helped :)

That really should have done it. Can you do a print_r on $this directly before running this line of code, then run it after? I'm suspecting there may be a different problem.

Was going to mention this :-)
