  Multiple database connection problem
Posted by: El Forum - 10-11-2007, 08:53 AM - Forum: Archived Development & Programming - Replies (4)

I am not able to open the multiple database connection using hooks.Here is the method I am using for this.

function loadDatabaseInfo()
// set the XML file name as a PHP string
$databaseConfList = getcwd()."/conf/database.xml" ;
// load the XML file
$xml = @simplexml_load_file($databaseConfList) or die ("no file loaded") ;
// assign the listName element to a string

// $xml->databaseGroup[1]->StudioName = "hello1";
// $filedata = $xml->asXML();
// file_put_contents($databaseConfList,$filedata);
$i = 0;
foreach ($xml->databaseGroup as $studioList)
$config = null;
$config['name'] = $studioList->Name;
$config['hostname'] = $studioList->configuration->Server;
$config['username'] = $studioList->configuration->DBUser;
$config['password'] = $studioList->configuration->DBUser;
$config['database'] = $studioList->configuration->DBPassword;
$config['dbdriver'] = "mysql";
$config['dbprefix'] = "";
$config['pconnect'] = FALSE;
$config['db_debug'] = TRUE;
$config['active_r'] = TRUE;
$DB[i] = $this->load->database($config);
echo $i++;

return null;

Can anybody please suggest how to get this done.

  Ideas for database structure / Dictionary
Posted by: El Forum - 10-11-2007, 08:22 AM - Forum: Archived Development & Programming - Replies (9)

Hello and sorry, if this a bit of a vague topic, but I'm in the early stages of a new project and not really experienced with the development of database structures—so every input would be very welcome.

Here's what I want to do:
I'm planning on a small app. that will work a little like a dictionary. That means I've at least two languages (let's say English and German) and vocabulary for both of them.
That would call for two tables:

English with ID and word and
German with ID and word

And since one word (like "to put") can have more than one meaning ("setzen", "stellen", legen") I'll need a third table for the relations between table "English" and "German".

Something like
ID, ID_eng, ID_ger
Am I correct so far? Is there a better way to handle something like this?

Now here's my bigger problem:
The amount of languages is dynamic. Let's say, somebody could add French or Chinese.
How would I handle the relations then? If I'd have an extra table for each relation I'll very soon reach a gigantic amount of tables. There gotta be a better way.
Any ideas, links or general input to the dictionary-in-a-database topic?

I'm in the planning stage and very grateful for every idea.
Thanks a lot,

P.S.: I know this is not necessarily CI related, but since the app. is going to be developed with CI and everyone in here always very helpful, I'm still going to give it a shot.

  callback from model
Posted by: El Forum - 10-11-2007, 08:16 AM - Forum: Archived Development & Programming - Replies (12)

For those interested in keeping validation inside model. As you all know you can't use callback method from model, or you can but callback function has to be inside controller. I have tried something else, so you can use my method if you want:

make new validation.php that extends CI validation and put it in application/libraries:


class MY_Validation extends CI_Validation {

    function MY_Validation()
    function additional_check($array)
        // do something with your data, set error message, return false or true
    $this->set_message('additional_check', 'error');
    return false;

in your controller construct load library and forms model:

in your model use callback as you would from controller, but without "callback_" prefix:

$rules['some_field']   = "required|additional_check";

callback will work without any problem, and you get to keep validation inside model, forms in one model, callbacks in one library. I like it that way, it keeps my controllers pretty clean, so if anyone wants to use this too, be my guest Smile

  Javacript and CI form arrays
Posted by: El Forum - 10-11-2007, 05:27 AM - Forum: Archived General Discussion - No Replies


This is probably a very simple question. Using the form helper I am passing an associative array containing the data I want the form to contain:

$data = array('name' => 'username', 'id' => 'username');

I also want to associate a JavaScript script with each form element. I can do this by:

$explain = 'onmouseover="explain(\'sidebar\', \'<p>Why do we need ..?</p>\')"


form_input($data, $explain)

Which is great. But I would like the JavaScript to have different variables passed to it depending on the element in question. Is it possible to do this by for example defining the JavaScript to be passed in the $data array rather than when the form is being written?

I hope that this makes sense.

  [validation] problem with validation library and htmlentites (strange conversion)
Posted by: El Forum - 10-11-2007, 04:10 AM - Forum: Archived Development & Programming - Replies (2)

Hi !
I have a problem with this code

$arr_data = array (
   "first"=>htmlentities ($this->validation->first),


In "first" field i try to use an htmlentites conversion, but when i insert the char 'à'
i obtain this conversion "Atilde sup2"(&Atilde;&sup2Wink instead of "agrave"(&agraveWink

Could you help me??

(i also tried to apply html entities directly in rules with $rules["first"]="htmlentities" but nothing changes)

  New UI Library in development
Posted by: El Forum - 10-11-2007, 03:20 AM - Forum: Archived Libraries & Helpers - Replies (7)

Hello, starting today I made public a small proof of concept on building interfaces in php directly with the help of jQuery UI components.

Details are Here in the wiki.

Simple usage as:


$this->ui->addTab("Some Tab", "<h1>Yay</h1>");
$this->ui->addTab("Some Other Tab", "<h1>Hooray</h1>");

$this->load->view("someView", array("tabs" => $this->ui->tabs()));

produces quality tabs in any layout.

This library uses an extended CI Loader class that will be discussed soon.

For details and download go here

  Blank page weirdness.
Posted by: El Forum - 10-11-2007, 01:19 AM - Forum: Archived Development & Programming - Replies (3)


I have a problem where a blank page is returned after I make a call to a search class I have but if I go to the controller and put in a simple echo statement it all works -- here's the weirdness -- if I then take the echo statement out of the controller (i.e. put the controller back to the way it was) it STILL works.

It carries on working for me for as long as I'm on the site but if I try the next day it's back to not working. The situation occurs in both IE and Firefox.

Of course I'd be grateful if anybody could shed some light?

  dynamic functions
Posted by: El Forum - 10-10-2007, 11:22 PM - Forum: Archived Development & Programming - Replies (4)

Hi there.. im new to code igniter.. started it about 3hours ago. and im in the middle of transforming my site to use CI framework. and im wondering how to go about this.

I have several users who are members of my site and part of the development team.
if you go to
about.php?u= {their username} it brings up a little bio
so how would i make it so that if they go to

i know i can go to about.php and make a function for each of their usernames and that will work, but i was hoping that there is another way to do it.

im sure this has been addressed before and its probably somewhere on the wiki or the forum but couldnt find it. Any help is greatly appreciated.
