Let’s say you have the form below – it has a multiple-file widget with fixed-aspect crop and client-side image resize.
<form method="POST" action="process.php">
<?php
echo $api->widget->getInputTag('qs-file', array( "data-crop" => "4:3", "data-images-only" => "true" ,"data-image-shrink"=>"1024X1024"));
?>
</form>
Then your process.php
should contain code that retrieves group URL similar to this:
<?php
$file_group_id = $_POST['qs-file'];
$fileGROUP = $api->getGroup($file_group_id);
$fileGROUP->data['url'];
?>
