    • How to open the file upload window?

    An example of uploading a file using linkToFileUpload

    Everything is done using linkToFileUpload

    = : linkToFileUpload(title: "Select file"; code: $code; limit: 1; type: "*"; refresh: true)

code: "=: set(table: $#ntn; field: 'h_file' = $#input)"

    The entire structure of the selected files is passed to the $#input variable.

    Also, if we enable the multiple parameter in the file field, we can use + — field: 'h_file' + $#input
