[rad11]

Co robie źle że $_POST i $_FILES jest pusty w PHP`ie?

[PHP] pobierz, plaintext 
 
<form method="post" action="/admin/offers/edit,{{$data->offer_id}}.htm" enctype="multipart/form-data">
 <input type="file" name="files" id="files" multiple>
</form>
 
$('#addImage').on('click', function (e) {
        e.preventDefault();
        var formData = new FormData();
        $.each($('#files')[0].files, function (index, value) {
            formData.append(index, value);
        });
        $.ajax({
            method: "POST",
            url: "/ajax/categories/add",
            dataType: "JSON",
            processData: false,
            contentType: false,
            data: {
                files: formData
            },
            success: function (response) {
                console.log(response);
            }
        });
    });
