Undesirable data change after rendering

[artbovboosta]

Please follow the general troubleshooting steps first:

• [ +] I read the README and followed the instructions.
• [ +] I am sure that the used CSL metadata follows the CSL schema.
• [ +] I use a valid CSL stylesheet

Bug reports:

Object $data contains different data before and after $citeProc->render($data, "bibliography"); operation.

Full code:

$data = file_get_contents("metadata_test.json");
$data = json_decode($data);

echo '<pre>'; print_r($data); echo '</pre>';

$style = StyleSheet::loadStyleSheet('apa');
$citeProc = new CiteProc($style);
echo $citeProc->render($data, "bibliography");

echo '<pre>'; print_r($data); echo '</pre>';

The result is:

In class Text.php, on line 106, there is "unset" operation which removes title field.

As objects are passed by references by default, I suggest to clone those objects before processing.

P.S. I noticed that this issue occurs only when "type": "webpage" and there is no authors.

Used CSL stylesheet:

apa

Used CSL metadata

[ { "URL": "www.starwars.com/", "accessed": { "date-parts": [ [ "2018", "09", "19" ] ] }, "id": "item-1", "title": "StarWars.com | The Official Star Wars Website", "type": "webpage" } ]
