Login form with one error message for any scenario

[eluser]SeasonedCoder[/eluser]
Howdy all,

I'm absolute newbie to CI. After reading the user guide I'm totally impressed :wow:

Well, I need to do the following simple task: I have a login form with username and password. But I don't want to display different error messages like "Username is required" or "Password must be at least X chars in length" for different scenarios. For me it's too verbose. All I want is to display a message like "Failed to login. Please enter valid username and password" in case the user fails to log in for whatever reason.

How do I do it using the form validation library? Any ideas?

Thanks in advance.

What I would do is have a custom callback for the password field which checks the username and password.

Use this->input->post() to access both the username and password in the custom callback function.

Dont set any rules for username as all the checking will be done in the password callback.

Welcome to the CodeIgniter forums.

I'd just do my validation as normal, and check for a form_error() on each of the fields, (rather than displaying them), then you can print whatever message you want in it's place.

@zutis

I was thinking about something like what you suggest: just have one callback to check both fields and set error message. So, I assume, this is viable solution.

@TheFuzzyOne

I'll try your approach as well, just to make myself more familiar with CI. Btw, you got awesome avatar LOL.
