    How to set the error message for maximum size of upload show immediately?

    Asked by Primasia on July 25, 2017 at 05:39 AM

    Hi there,

    Please advise what is the max. file size (more than 3 files need to be uploaded)  that can be uploaded to the form? And if i set the size limit, once the user upload a file that is exceed the limit, will a notice pop up notify user the file is too large?

    Please be advised that you have to manually change the maximum upload size, here you are the guidelines:


    If the uploaded file size is larger than what is set up, an error message is shown stating file is not uploaded, as shown below:

    Hi Aury,


    Thanks for your reply. In my case I didn't know the file was over the set limit until I submitted the form. As it is a long form so i need to go all the way back. Please advise how to make the error message appear immediately like you've shown above?

    The error message will show as soon as you click anywhere outside of the upload field or you click submit.

    But, maybe a workaround would be to enable multiple uploads:

    And set the Limit of files to 1.

    That way the error message will show immediately:

    Hope it helps.

    If you have any further questions please let us know.

    Thank you!
