I would like to change the default error message from Drupal core.
The error message is "Please Select the Valid File Format".
My problem is in brief below.
- I have created a CCK called 'Assignment'.
- There I have given the users an option to upload files.
- In such case if the user uploads invalid file format drupal will throw the error message as mentioned above.
- I need to change the error message in to "The file upload field cannot upload the speicified filed".
How can I achieve this?
(Should not use string overrides module)
Thanks in advance..
