check fileuploadsize before submitting, save forminput with button before submitting

rincewind 16 Oct, 2016
Hi, i have 2 questions,
first: Is it possible to insert a button in the form to export the data which is already written there? something like an exel-export or similar. People should be able to save their input before submitting it.
second: can i check the file uploadsize before submitting? after choosing a file for upload it should instantly checked if too big.

thx

Hi rincewind,

To allow people to save data before submitting I'd suggest that you use a 'Confirmation' page - a second page in the form where the entered data is displayed before final submission. You could add a Print button to that page to allow them to keep a record.

ChronoForms doesn't have any built-in way to check the file-size before uploading. Basically, the browser doesn't have access to that info. HTML5 does allow access to the fie-size data and you can add a validation using code like this StackOverflow answer - but it won't work with older browsers.
