Random Usernames and Passwords
From TMM Wiki
NATS 3
|
|---|
You can give members random usernames and passwords when they sign-up by adding a hidden field to the NATS Pre-Join Form template. The field's name must be signup[random_userpass]. The fields value should contain three to four parameters separated by colons.
On older NATS versions, you can only use this if you want both a random username and a random password generated for the member. On NATS versions 4.1.10.1 and above, if either username or password is blank on the join page submit and signup[random_userpass] was used, NATS will generate random values for the field that is blank.
Parameters
(Required parameters in bold)
| Name | Description | Possible Values | Default Value | Example |
|---|---|---|---|---|
| Length | Number of characters in the username and password | Any whole number between 6 and 16 | None. You must specify a length | 16 |
| Lowercase | Only use lowercase characters in the username and password | 0 or 1 (exclusive) | 0. Uses lowercase and uppercase characters | 1 |
| Maximum Searches | How many times should NATS try to generate a unique random username before failing | Any whole number greater than zero | 10. Tries to generate a unique random username 10 times | 20 |
| Username Prefix | Append a prefix to the random username | Any combination of #s and letters | None (optional). A prefix is not required. | abcd |
Currently, the Username Prefix is used for both Username and Password
You should add the $errors.username variable to the join page so NATS can
display username errors.
Note: NATS may throw an error if the random username happens to be generated with a number as the first character, in this case we recommend adding a prefix character to the random string.
