File Upload Control
fileInput(inputId, label, multiple = FALSE, accept = NULL)
|inputId||Input variable to assign the control's value to.|
|label||Display label for the control.|
|multiple||Whether the user should be allowed to select and upload multiple files at once. Does not work on older browsers, including Internet Explorer 9 and earlier.|
|accept||A character vector of MIME types; gives the browser a hint of what kind of files the server is expecting.|
Create a file upload control that can be used to upload one or more files.
Whenever a file upload completes, the corresponding input variable is set to a dataframe. This dataframe contains one row for each selected file, and the following columns:
- The filename provided by the web browser. This is
not the path to read to get at the actual data that was uploaded
- The size of the uploaded data, in bytes.
- The MIME type reported by the browser (for example,
text/plain), or empty string if the browser didn't know.
- The path to a temp file that contains the data that was uploaded. This file may be deleted if the user performs another upload operation.
