unexpected error: Unable to load the requested file: helpers/login_helper.php

[eluser]wagnered[/eluser]
Attempting to get familiar with CI and the C-V-M approach, I tried the form validation example from the documentation.

I entered the code for the controller, the form and the success page, verbatim. The URL I gave was http://127.0.0.1:8080/index.php/form as suggested by the example. When I did, I got the error "Unable to load the requested file: helpers/login_helper.php". I did not add the request for the helper to the code.

I did a grep and find of the directory tree for the phrase "login_helper" and login_helper.php and found nothing: no references or no file by that name. I was checking to see if it might have been included indirectly somehow.

I'm using lighttpd and php 5.5.17 on a Linux machine.

Does anyone have an idea how that helper is being requested if it's not in my code or referenced in any file on the system?


Thanks....

Have you got a link to this "Example" you are trying?

file://.../.../user-guide.toc.html.

Wherever you installed your version of the codeigniter user_guide folder. In the table of contents, select "Form Validation class" and you will see the code.

Well I recopied/pasted the code into their respective files and could not reproduce the error listed in the title. Must have been a bad character that got inserted somewhere.

But, now, the web page is blank.

I wonder if the form and url helper or the form_validation library is not getting loaded.

I downloaded CodeIgniter-3.0 and tried the same example and the "Form Validation example" worked.

So I copied the files from that version to 2.2.0 and as long as I entered the url with the controller part exactly the same as the controller file name, it worked: if the controller file name is "Form.php" I had to use that in the url. In 3.0 I could use either first letter upper or lower case.

So 3.0 seems a little more forgiving in referring to the controller at various places in the code.

I'm familiar with PHP and even C++ as to the letter case of variables, etc. The quirks of CodeIgniter add another layer to get familiar with as to understanding how the different parts (M-V-C) operate together.
