Hi @AnilJ ,
Try below onSumbit catalog client script.
function onSubmit() {
// Get the file upload variable (replace 'file_variable_name' with the actual name of the file upload variable)
var fileVar = g_form.getValue('file_variable_name'); // Ensure this is the variable name of your file upload field
// Check if a file has been uploaded
if (fileVar) {
// Get the file extension (get the part after the last dot in the filename)
var fileExtension = fileVar.split('.').pop().toLowerCase();
// If the file extension is not '.msg', show an error message
if (fileExtension !== 'msg') {
g_form.showFieldMsg('file_variable_name', 'Please upload a valid .msg file.', 'error');
return false; // Prevent form submission
}
}
// If the file is valid, allow the form submission
return true;
}
Please mark as Correct/helpful or accepted solution if it solves your issue.
Best Regards,
Pooja
