global controller??

Posted by: El Forum - 06-07-2008, 10:05 PM - Replies (2)

	[eluser]nuttynibbles[/eluser] hey guys, is there a way to extend controller from another controller. my controllers basically initiate almost the same variable in the constructor and I was thinking if I could do a parent controller which extends from "Controller" libraries and basically the rest of the controllers will extend from my created parent controller.

Class and Function URI segments redundant - how to work around them?

[eluser]Aquillyne[/eluser]
There are plenty of occasions when I don't actually need to specify my class and function, but I am forced to. Is there a way to get straight into the "id" part, i.e. the part that is passed as a parameter?

For instance, I want a welcome controller that does nothing more than output something from the URI. I want to go to mysite.com/<foo> and see <foo> on the page - that's it.

Without CI this is ridiculously easy. The index.php file just echoes what's in the $_GET. A .htaccess file, as with CI, reduces mysite.com/index.php?=foo back to mysite.com/foo. Easy. But how to do this with CI?

A similar case. A function in my welcome controller accepts a parameter. Why must I go to mysite.com/welcome/function/param rather than just mysite.com/function/param, when the "welcome" has been implicit all along? This is basically the same question as before: why do I have to specify mysite.com/welcome/index/param rather than just mysite.com/param when the "welcome" and "index" were previously implicit?

Note that I only want this to happen on particular pages, which is again very easy without CI. My "foods" page may have no further functions, and hence just immediately accept a parameter. I can use mysite.com/foods.php?=param, or mysite.com/foods/param to do this. But in CI, the foods/param is assumed to refer to a function "param" in the "foods" class. How do I specify, only on the "foods" page, that the second URI segment is to be passed as a parameter?

Is there a way to work around this? Thanks for any help.

Error 'Undefined property' when loading model to controller

Hello to everyone!

I have the code:
news.php:

Code:
&lt;?php

  class News extends Controller

  {

    public function ru()

    {

      $data['xml_lang'] = 'ru';

      $data['title'] = 'Официальный сайт брутал-дэт группы Fleshbomb - Новости';      

      /*$this->load->helper('url');

      $data['main'] = anchor('news/ru', 'Главная');*/

      $data['published'] = 'Опубликовано';

      $this->load->model('news_model');

      $data['news'] = $this->news_model->get_last_three_entries($data['xml_lang']);

      $this->load->view('newsview', $data);

    }

    public function en()

    {

      $data['xml_lang'] = 'en';

      $data['title'] = 'Fleshbomb brutal-death band Official Site - News';

      /*$this->load->helper('url');

      $data['main'] = anchor('news/en', 'Main');*/

      $data['published'] = 'Published';

      $this->load->model('news_model');

      $data['news'] = $this->news_model->get_last_three_entries($data['xml_lang']);

      $this->load->view('newsview', $data);

    }

  }

?&gt;

news_model.php:

Code:
&lt;?php

  class News_model extends Model

  {

    public function __construct()

    {      

            parent::Model();

            $this->load->database();

    }

    public function get_last_three_entries($lang)

    {      

      $sql = "SELECT p_date AS date, p_title_$lang AS title, p_content_$lang AS content FROM site_news LIMIT 3";            

      $query = $this->db->query($sql);

      return $query->result_array();

    }

  }

?&gt;

and newsview.php:

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

&lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="&lt;?php echo $xml_lang; ?&gt;" lang="&lt;?php echo $xml_lang; ?&gt;"&gt;

&lt;head&gt;

    &lt;title&gt;&lt;?php echo $title; ?&gt;&lt;/title&gt;

  &lt;meta name="keywords" content="brutal-death, grindcore, grind-core, goredeath, gore-death, fleshbomb, nosorog" /&gt;

  &lt;meta name="description" content="Moscow gore-death band official site. Full discography, biography, gigs, videos" /&gt;

  &lt;link rel="stylesheet" type="text/css" href="../../system/application/media/css/style.css" /&gt;

&lt;/head&gt;  

&lt;body&gt;

    <div id="sidebar-left">

        <ul id="menu-list">

            <li><a href="#">Menu item</a></li>

        </ul>

    </div>

  &lt;?php foreach($news as $item): ?&gt;

  <div class="news-block">    

    <h3 class="news-title">&lt;?php echo $item['title']; ?&gt;</h3>

    <div class="news-date">&lt;?php echo $published . ': ' . date('d.m.Y H:i:s', $item['date']); ?&gt;</div>

    <div class="news-body">&lt;?php echo $item['content']; ?&gt;</div>

    <hr />

  </div>

  &lt;?php endforeach; ?&gt;

&lt;/body&gt;

&lt;/html&gt;

On my local server (MAMP 1.7.1) it works just fine. Even if I used $this->load->model(Uppercase_name) or $this->load->model(lowercase_name).
But when I put it on hosting server I have get error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: News::$news_model
Filename: controllers/news.php
Line Number: 12
Fatal error: Call to a member function get_last_three_entries() on a non-object in /pub/home/artwiko/htdocsfb/dev/system/application/controllers/news.php on line 12
For the /news/ru.html.
And:
Fatal error: Call to a member function get_last_three_entries() on a non-object in /pub/home/artwiko/htdocsfb/dev/system/application/controllers/news.php on line 24
For the /news/en.html
I can't understand what I doing wrong.
Could somebody help please?

Advanced MySQL: Active Record Query not working properly?

Posted by: El Forum - 06-07-2008, 09:04 PM - Replies (6)

[eluser]MercuryLime[/eluser]
Do you have an idea how to write:

Code:
$query = $this->db->query('SELECT c.title, c.description, r.completion_notes, r.outcome FROM challenges AS c, records AS r WHERE c.id = r.challenge_id AND r.user_id = ' . $user_id . ' AND r.outcome = "ip" LIMIT 100');

as an Active Record Query?

I tried the following, but it returned 0 results.

Code:
$this->db->select('c.title, c.description, r.completion_notes, r.outcome');

        $this->db->from('challenges AS c, records AS r');

        $this->db->where(array('r.challenge_id' => 'c.id', 'r.user_id' => $user_id, 'r.outcome' => 'ip'));

        $this->db->limit(100, 0);

        $query = $this->db->get();

Help would be appreciated!

How to load a view for the error page?

Posted by: El Forum - 06-07-2008, 08:57 PM - Replies (25)

	[eluser]Aquillyne[/eluser] Hi, I'm new to CI. I'm very impressed so far but have a question - could anyone help out? I want error messages from my site to appear as messages in one of my normal views, rather than as hard-coded messages from the /errors folder. Is there a way to load a view within/instead of an error message? Thanks.

simple & helpful DB class for CI

Posted by: El Forum - 06-07-2008, 08:18 PM - Replies (4)

[eluser]vps4[/eluser]
It’s simple and useful MySQL DB class.
I modify it from WordPress2.5.1 wp-db.php

It also automatic load DB config from CI config file.

Usage:

just put it in your CI app library folder, usually in system/application/libraries
and name Db.php

now , you can load the library anywhere, or set it automatic load in autoload config file

Code:
$this->load->library('db');

these method is better than CI database, only ONE line code.

Code:
$this->db->get_var($sql);

$this->db->get_row($sql);

$this->db->get_col($sql);

$this->db->get_results($sql);

enjoy it!!!

I can’t post the code to here, because it’s so long

please get it from

http://www.21andy.com/blog/20080607/1156.html

anyway, sorry for my poor english.

mysql_result Equalvilent in CodeIgniter

Posted by: El Forum - 06-07-2008, 06:56 PM - Replies (2)

[eluser]helloadam[/eluser]
Howdy,

I am converting a backend application into CodeIgniter. I have came across a small issue that is driving me nuts.

I have searched the wiki/user guide and forums but found no such of a solution.

My application is doing something like so,

Code:
$get_settings = $this->db->query("SELECT `data` FROM `". $this->tablePrefix ."settings` WHERE `vkey`='t_cstatusupd'");

$settings = mysql_result($get_settings,0,'data');

But I am unsure how to handle the mysql_result part. I noticed the ->row object is similar to the mysql_result part however, it does not accept the other two parameters that the script requires.

Any tips, suggestions, etc?

Thanks,
Adam

FIXED: Calling other model functions from within same model

Posted by: El Forum - 06-07-2008, 12:45 PM - No Replies

[eluser]MercuryLime[/eluser]
I've searched around on this forum looking for help, but found no solution.

Basically, I am calling another function in my model code and I have identified that the specific line is breaking the code. I don't know why!

Here is the model (irrelevant functions removed).

Any ideas why that line is breaking the code?

Code:
&lt;?php

class Challenges extends Model {

    function Challenges()

    {

        parent::Model();

    }

    function get_challenge ($condition = array()) {

        // Returns challenge object based on supplied conditions array (usually, single associative array with key 'id')

        $query = get_where('challenges', $condition, 1, 0);

        if($query->num_rows() == 1) {

            return $query->row();

        }

        else {

            return FALSE;

        }

    }

    function get_current_challenge ($user_id) {

        // returns object of the challenge table row (currently with keys 'id', 'title', 'decription', 'tags', 'date_created', 'submitter_id', 'approved')

        // 1) Determine the challenge_ id of the current challenge of the user

        // 2) Return the object of the challenge table row with that id 

        $this->db->select('challenge_id');

        $query = $this->db->get_where('records', array('user_id' => $user_id, 'outcome' => 'ip'), 1, 0);

        if($query->num_rows() > 0 ) {

            $row = $query->row();

            return $this->get_challenge(array('id' => $row->challenge_id));

// THIS LINE IS BREAKING THE CODE ^^^

        }

        else {

            return FALSE; //  User has no current challenge...? Deal with this.

        }

    }

}

?&gt;

EDIT: *groan* Yes, it is possible to access different functions in the same method. I made a mistake using the Active Records get_where function.

Hours down the drain!
