Hi

Is there any way to check file size via Codeless? I need it to set limit on uploaded file size from user.

I have put a similar request into the Forum specific for images. See

Image compression/resize before upload

Hi, I’m using this forum to suggest a feature which I miss and of which I feel it would be very useful. It’s about resizing and compressing an image before uploading it to the server. Problem: backendless knows the File Upoader Button. A common use case is to let users of an app upload images to the server (images of food, for profiles, selfies, landscapes and cats). As a developer, I’m worrying about the amount of data which could pile up if each user is uploading mobile smartphone photos o…

Checking the file size would be another essential feature for the onBeforeUpload event.

@mark-piller : This only works for “include subdirectory: true”. Setting this to “false” returns the error:

400 - Cannot read property 'size' of undefined
{
    "code": 0,
    "message": "Cannot read property 'size' of undefined",
    "errorData": {}
}

Is this as expected?
Thanks

Not, including subdirectories is not required. The error tells me the “directory listing” block returned 0 results.
