theme_material | Material Theme For Quokka CMS Front End | Content Management System library

i created this extension a few months back. The files that you submitted will be in the $_FILES array and not the $_POST and you need to call the UploadedFile::getInstances('image') to get all the images you selected to upload and then iterate on them to upload, you can access all the properties listed here for every image.

And you are not creating the new object every time you are inserting the image inside the foreach ($_FILES['ListingImages']['name']['image'] as $key => $image) { which will show only the last image inserted , your $imageModel is initialized in the start of the action whereas you should have it inside the foreach too
