Limit number of files for Multi file select

pat01 07 Feb, 2020

Hello

I use an upload field for uploading JPG files. I have enabled "Multi file select".

Is there a way to limit the number of files for upload?
I want the user to select 15 files maximum.

Thanks.

Use a validate data action

fileUploadFieldNameGoesHere/maxCount[15]:You have selected too many files!

Something similar in the front end - go to the validation tab of the file upload field and under Validation rules put in

maxCount[15]:You have selected too many files!

Hi Patrick,

Just as a side note you may hit server limitations or get very slow responses if users upload 15 images.

Hi healyhatman and hi Bob

I did check upload max number of files, so no problem there. However, I do testing with 3 files to be on the very safe side🙂

I did try:

maxCount[15]:You have selected too many files!

But I still can submit the form.

My goal is to show an error message and pretend the form from beeing submitted if number of files is more than three.

I guess this should be possible with

maxCount[15]:You have selected too many files!

?

Thanks.

Yeah front end doesn't look like it's going to work sorry, you're going to have to do it with jQuery. Use the "custom javascript validation" FAQ and something along the lines of https://stackoverflow.com/questions/10105411/how-to-limit-the-maximum-files-chosen-when-using-multiple-file-input

Just remember you need to use jQuery() not $()

OK, thanks. I'll check it out.
