hi everyone

i am just starting out with CI - i really want to use it for a website i am starting - however - i cant seem to get my head around how to have a login form on every page.

at the moment i have the login form as part of my header.php in the “views” folder. but that is as far as I can get.

i want to just use my own login code (which simply checks the db and sets the sessions - or returns an error message) but i have no idea how to set this all up in the mvc approach. i also dont know how to redirect the user back to the same page they were viewing before submitting the login form (i would normally use hidden or get fields here if I wasnt using CI).

basically - i am lost. any help would be appreciated - if i can get past this i know CI will be very beneficial.

cheers.

Check out my new mini-app download…. it has the code example as a little app that does nothing but user authorization.

Try the link again… your post was while I was setting up the post right b4 yours. My link was initially broken… but fixed… You will find good code example for your question

Create a view that is included on every page.
Create a form with a hidden value of ‘$this->uri->uri_string()’. Have the form action as as ‘/login/’.
Create a Login controller that does the login. Have the Login controller ‘redirect($this->input->post(“hidden_url”)’.

Done. Obviously, you’d want error checking, etc, but that’s the basic concept.

thanks shadowhand - that really helped.. i have now mostly got it all working.

one problem i had was that $this->uri->uri_string() wasn’t outputting anything for the hidden field (i tried echo’ing it too). I have definitely got the uri library in the autoload.php file.
i have just used PHP_SELF instead for now and it all works.

instead of $this->uri->uri_string() in a hidden filed you can also use native-session and their flasvars feature.

Did you figure out how to use login form on every page, when your using the ci validation class. Since validation code is usually in the controller.

The mini-app doesn’t use ci validation on the loginform…

You might also look into the FILTER system on the wiki page.

http://www.codeigniter.com/wiki/Filters_system/

I’ve incorporated it in my application and it took 5 minutes only.

I’ve edited the file: system/application/filters/auth.php to suit my needs.

Ananda - I didnt use the validation functions for the login part - but i have used it on the registration page and i think it is fantastic and so easy to use!
Shaffick - i will look into the filters system thanks.

I have the login system working well now. thanks for everyones help.
I am really starting to love CI - I like how i can use as little or as much of the MVC approach as I like.
