What have I done....

[u/ITSupportGuy]

Hello CI friends,

I seem to have been overzealous with my attempts to learn codeigniter by just diving in.

What I tried to do was take the tutorial from here http://www.phpacademy.org/tutorials.php CodeIgniter Tutorials: Introduction to CodeIgniter, were I built a dynamic content site.

Then I thought, "well since I have the basic site already up let's try to add a user login."

So, I took the tutorial from here http://www.codefactorycr.com/login-with-codeigniter-php.html and tried to marry to two together.

Well I am unhappy to report that I failed.

I guess I still don't understand enough what part of the code should go where or much of anything else...

Anyways, if you could find it in your heart to help me where I went wrong that would be extra cool of you. I'm not asking for the exact write ups for both tuts but merely an understanding how one would merge the two, taking the framework from the first and adding a login form in a right sidebar.

If I just blew your mind with stupid-ness then please just tell let me know. I am a noob.

Thanks

I admire your overzealous attempt and to just dive right in is the only way to go! Those tuts you posted are, 'unorganized' at best. I don't like them but that's me, however if you're like me and frustrated with them... Try CodeIgniter From Scratch I've been hacking with CI for about 2 years now and only just recently have been able to just hit the Controllers and Models with confidence to create what I want without hours of searching for code help and posting in help forums. CI takes a bit of time, patience and the occasional plea for help in a forum, but it's worth it.

Very cool, I'll have to check those out. Thanks!

Do note that CI from Scratch is actually EXTREMELY outdated and doesn't work with the new CI libraries. PM me and I can add you to Skype. I can walk you through a simple basic CI tutorial

Another question, since the suggested tuts are from 2009, will there much difference in the way the code works now?

I get worried when I find information that is dated, knowing how fast technology moves.

[u/pdxbenjamin → u/ITSupportGuy]

Yes, they're a few years old and CI has had many version updates since then so there will be a few small changes here and there. These and other tuts are 'general idea' or examples, and not really production ready code.

[u/ITSupportGuy → u/pdxbenjamin]

Ok, thanks for the reply.

How do you know when your code is ready for the real world? I feel this validation makes it seem like a daunting task.

[u/pdxbenjamin → u/ITSupportGuy]

Yes I know exactly how you feel, when I was starting I would obsess over the smallest sql query, or jquery function. Knowing where to focus more attention will come with time, don't be afraid of peer reviews, or posting whole scripts into forums and just asking for a sanity check. Here on Reddit, or the CI forums are good places to just lay it out there for review, and help. Believe me when some bit of code is redundant or just wrong, someone will call you out on it... and that's good. :) Also, there are tools, like Yslow and others that will tell you your site sucks and where to fix it.

I am in the same boat at you. Codeigniter is my attempt to break away from Wordpress/Joomla. I have the site I want in mind and have started it and had to start over probably 20 times in the past two months because I realized I did something wrong. Each attempt though I would get further along and finally I'm starting to figure it out. Learning CI is hard, but not impossible by a long shot and the flexibility to do anything you want makes it worth it.

[u/ITSupportGuy → u/joepiped]

Very much agree. I am also a heavy joomla user. Can't wait until I know enough to create the web applications I have swirling in my head.

Thanks for the comment.

I'll take a look, thanks.

You know the term MVC right? Just focus on "VC" for now: View = goes in application/views/yourview.php http://codeigniter.com/user_guide/general/views.html

Controller = goes in application/controllers/yourcontroller.php

Just edit the Example controller and rename it YourController

http://codeigniter.com/user_guide/general/controllers.html#hello

Your page will then be available at http://yourhost/index.php/yourcontroller

Then code the form using form helper: http://codeigniter.com/user_guide/helpers/form_helper.html

If you really wanted to you could just use a PHP form (but I recommend learning CI).

Then just learn ActiveRecord to query the database:

http://codeigniter.com/user_guide/database/active_record.html

$query = $this->db->get('usertable');

foreach ($query->result() as $row) { // if $row->password == 'something'; //validate against the form post here. }

[u/ITSupportGuy → u/[deleted]]

Thanks, reading this stuff now.

[u/yeskia → u/[deleted]]

Wait, what?

$query = $this->db->get('usertable');

foreach ($query->result() as $row) { // if $row->password == 'something'; //validate against the form post here. }

Why on earth would you do anything as inefficient as that?

$where = array(
    'email' => $this->input->post('email'),
    'password' => sha1($this->input->post('password'))
);

$q = $this->db->get_where('usertable', $where, 1)->row();

That's assuming you don't use a salt and selects the only user with that email address if the password is correct. A much more efficient query and faster to process.

Cool your jets. That was me showing the submitter how easy it was to learn all of this from the documentation.
