im trying to send an array from javascript to Joomla 3.x php file.

var options = ['foo', 'bar'];

$.post('index.php?option=component&view=componentview&Itemid=123&tmpl=component&layout=xlsx', {'xlsx_options': options})

Then, I have a php file which creates data in order to download xlsx file. But I need to filter by this options array and Im not able to retrieve it. I've tried this without success.

$xlsx = $_POST['xlsx_options'];
$xlsx = json_decode($_POST['xlsx_options'], true);
$xlsx = JFactory::getApplication()->input->get('xlsx_options');

Any help? Thanks!

You firstly need to encode your array in Javascript, like so:

var options = JSON.stringify(['foo', 'bar']);

$.post('index.php?option=component&view=componentview&Itemid=123&tmpl=component&layout=xlsx&options=' + options);

Then in your PHP code, use the following instead of $_POST:

$input = JFactory::getApplication()->input;
$xlsx  = json_decode($input->get('xlsx_options'));

echo $xlsx->foo;
echo $xlsx->bar;
