Validation library usage for form validation. Need help - El Forum - 09-15-2010

[eluser]prashid[/eluser]
I am using Validation library as autoload. Now problem is when I type in URL
http://localhost/CIB/test/ get error below and if browse http://localhost/CIB/test/check_user working fine.
I understand that default values are required if not calling check_user.
But I don't want to call check_user as default instead I want to call default index at start and once
user click button than check_user should be called. Am I right here?

So whats the solution here?. Should I use defaults in order call index at start? if yes whats the professional way to code
when there are many fields.

Thanks


Code:
//ERROR
A PHP Error was encountered
Severity: Notice
Message: Undefined property: CI_Validation::$username_error
Filename: views/test_view.php
Line Number: 11

&lt;?php echo form_close()?&gt;

&lt;/body&gt;

Validation library is deprecated in 1.7.2 (removed in 2.0) and replaced with form_validation, so you're not going to get much help with it.
