Title Body

I'm using FormData to upload files. I also want to send an array of other data. When I send just the image, it works fine. When I append some text to the formdata, it works fine. When I try to attach the 'tags' array below, everything else works fine but no array is sent. Any known issues with FormData and appending arrays? Instantiate formData: formdata = new FormData(); The array I create. Console.log shows everything working fine. // Get the tags tags = new Array(); $('.tag-form').each(function(i){ article = $(this).find('input[name="article"]').val(); gender = $(this).find('input[name="gender"]').val(); brand = $(this).find('input[name="brand"]').val(); this_tag = new Array(); this_tag.article = article; this_tag.gender = gender; this_tag.brand = brand; tags.push(this_tag); console.log('This is tags array: '); console.log(tags); }); formdata.append('tags', tags); console.log('This is formdata: '); console.log(formdata); How I send it: // Send to server $.ajax({ url: "../../build/ajaxes/upload-photo.php", type: "POST", data: formdata, processData: false, contentType: false, success: function (response) { console.log(response); $.fancybox.close(); } });
