Restrict specific file type while uploading

[mohitchechani]

The upload from my device with restriction is working

But from library is not working

@mohitchechani Apparently adding restrictions to the library uploads needs some Python coding…

I will inform you when I’m done…

to restrict file upload on frappe path :- apps/frappe/core/doctype/file//file.json { "fieldname": "file_type", "fieldtype": "Select", "label": "File Type", "options": "JPG\nJPEG\nPNG\nPDF\nCSV\nXLS\nXLSX", "in_list_view": 1, "in_standard_filter": 1, "read_only": 1 }

The provided script is functional in version 14, and I trust it will meet your requirements as well.

frappe.ui.form.on('doctype_name', {
    validate: function (frm) {
        // Get the file field
        var fileField = frm.doc.field_name;

        // Check if the file field is empty
        if (fileField) {
            // Define allowed file extensions
            var allowedExtensions = ['.xls', '.xlsx', '.csv'];

            // Get the file extension of the selected file
            var fileExtension = fileField.split('.').pop().toLowerCase();

            // Check if the file extension is allowed
            if (!allowedExtensions.includes('.' + fileExtension)) {
                frappe.msgprint(__('Only files with extensions ' + allowedExtensions.join(', ') + ' are allowed.'));
                frappe.validated = false;
            }
        }
    }
});

Check this post for a Client Script restricting the allowed file types for an Attach field (tested on develop / v16):

Attach field type - Allowed file extensions

You can achieve this via the following Client Script: frappe.ui.form.on("MY DOCTYPE", { refresh: function (frm) { const attach_field = frm.fields_dict["MY FIELDNAME"]; attach_field.on_attach_click = function () { attach_field.set_upload_options(); attach_field.upload_options.restrictions.allowed_file_types = [ "application/xml", "text/xml", ]; attach_field.file_uploader = new frappe.ui.FileUploader(attach_field.upload_options); }; } }); Tested on develop / v16.
