Passing data around from view to view unlimited number of times without rebuilding the data array

2012-02-13T09:48:25+00:00

I’m loading views from within views multiple times and to avoid rebuilding the data array i create a self-reference to it.

$data=array();
$data[‘data’]=&$data;

then set some other values

$data[’ .. ‘]= ...

then load the view

$this->load->view(‘view1’,$data);

Inside view1 i have
<?php $this->load->view(‘view2’,$data); ?>

Inside view2 i have
<?php $this->load->view(‘view3’,$data); ?>

And in view3 i use some of the variables in $data.

My question is: are there any reasons not to use this method?

Code example below:

Controller

function index()
{
 $data=array();
 $data['data']=&$data;  // self reference that i use
        $data['page_title']='title';
        $data['footer_text']='bye';
        $data['js_files']=array();
        $data['js_files'][]='/etc/main.js';
        //etc..
 $this->load->view('page/index.php',$data);
} 

View: page/index.php

$this->load->view('layout/header.php',$data);
...
<b>main body html</b>
... 

View: layout/header.php

<head><title>
<?php if(isset($page_title)) { echo $page_title; } else { echo ' Default Title '; } ?>
</title>
<?php 
if(isset($js_files) && is_array($js_files)) {
   $this->load->view('layout/js_files.php',$data);
} 
?>
</head><body> 

Thank you for your time!

url wierdness

2012-02-12T00:08:03+00:00

hey guys,

I have a funny thing that happens to my local setup for development. I have a form with action like so:

<div class="entry">
              <p>
                  <form action="students/loginstudent" method="POST" id="studentlogin">
                  <p><label for="Username"><strong>Username :</strong><input name="user_name" id="uname" type="text"/></label></p>
                  <p><label for="Password"><strong>Password :</strong><input name="password" id="password" type="password"/></label></p>
                  <p><input name="submitbtn" id="logbtn" type="submit" value="Login"/></p>
                  </form>
           </p>
     <?php 
            echo '<p class="errors"><strong>'.$this->ion_auth->errors().'</strong></p>';
            echo '<p class="errors"><strong>'.validation_errors().'</strong></p>';
                    
     ?> 

and I have a function in my students controller called loginstudent. Now when I try to login I am brought back to the login form again but the url says this:


http://localhost:8888/schoolmanager/index.php/students/students/loginstudent

so my question is has anyone encountered this before? I thought of sharing this here first as I think this is the best place to start finding answers.

Thanks for all the help!!!

Extending controller with function

2012-02-11T21:58:58+00:00

Hello All !

Im a noob in codeigniter an started to work with it, everything seems to be ok till I had to implement function that will reside in almost all controllers and it has a task to log in mySQL some actions that user did.

So, my question is how can I include function that will do some logging action after model returns success, in almost every controller that I have ?

Kind Regards,
Robert

pagination and uri_segment

2012-02-09T12:01:58+00:00

Hello!

i’m too new to CI to prentend having ancounter a bug. There’s must be a mistake in my code! I’ve read documentation and browsed forums but i can’t find where!

Any help is welcome:

I want to a simple pagination with sorting features. Here is the code:

<?php
class Projects extends CI_controller {

 function display($sort_by = 'id', $sort_order='desc', $offset = 0) {

  $limits = 30;

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

  $results = $this->project_model->search($limits,$offset,$sort_by, $sort_order);
  $data['projects'] = $results['rows'];
  $data['num_results'] = $results['num_rows'];

  //pagination
  $this->load->library('pagination');
  $config = array();
  $config['base_url']=site_url("projects/display/$sort_by/$sort_order/$offset");
  $config['total_rows'] = $data['num_results'];
  $config['per_page'] = $limits;
  $config['uri_segment'] = 5;

  $this->pagination->initialize($config);
  $data['pagination']= $this->pagination->create_links();

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

        }

}
?> 

The search function works great, i can type url such like:

http://10.153.9.6/dev/index.php/projects/display/id/desc
http://10.153.9.6/dev/index.php/projects/display/id/desc/10
http://10.153.9.6/dev/index.php/projects/display/counrty/asc/400
http://10.153.9.6/dev/index.php/projects/display/name/asc/11

But the pagination links are wrong, I obtain:

http://10.153.9.6/dev/index.php/projects/display/id/desc/0/240

instead of:

http://10.153.9.6/dev/index.php/projects/display/id/desc/240

I thought the problem was in the “uri_segment’, but I think 5 is the correct value:

// base url                    / 1      / 2     / 3/ 4  / 5
http://10.153.9.6/dev/index.php/projects/display/id/desc/240 

I’ve missed something. Any idea?

thanks!

is_unique is not working?

2012-02-09T08:25:13+00:00

Hello,
I am using CI 2.0.0 and validate function is_unique is not working.
This is code my register users controller:

public function registration()
 {
  $this->load->library('form_validation');
  $this->load->database(); 

  $this->form_validation->set_rules('email_address', 'Email', 'is_unique[users.email]|required|valid_email');
  
  $this->form_validation->set_rules('user_name', 'User Name', 'trim|required|min_length[4]|xss_clean');
  $this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_length[32]');
  $this->form_validation->set_rules('con_password', 'Password Confirmation', 'trim|required|matches[password]');

  if($this->form_validation->run() == FALSE)
  {
   $this->index();
  }
  else
  {
   $this->user_model->add_user();
   $this->thank();
  }
 } 

This is views for register forms:

<div id="content">
<div class="signup_wrap">
<div class="signin_form">
 <?php echo form_open("user/login"); ?>
     <label for="email">Е-майл:</label>
     <input type="text" id="email" name="email" value="" />
     <label for="pass">Парола:</label>
  <input type="password" id="pass" name="pass" value="" />
        <input type="submit" class="" value="Вход" />
    <?php echo form_close(); ?>
</div><!--<div class="signin_form">-->
</div><!--<div class="signup_wrap">-->
<div class="reg_form">
<div class="form_title">Вход</div>
<div class="form_sub_title">Регистрирай се безплатно сега!</div>
<?php echo validation_errors('<p class="error">'); ?>
 <?php echo form_open("user/registration"); ?>
  <p>
   <label for="user_name">Вашето име:</label>
   <input type="text" id="user_name" name="user_name" value="<?php echo set_value('user_name'); ?>" />
  </p>        
  <p>
   <label for="email_address">Вашия е-майл:</label>
   <input type="text" id="email_address" name="email_address" value="<?php echo set_value('email_address'); ?>" />
  </p>
  <p>
   <label for="password">Парола:</label>
   <input type="password" id="password" name="password" value="<?php echo set_value('password'); ?>" />
  </p>
  <p>
   <label for="con_password">Повтори паролата:</label>
   <input type="password" id="con_password" name="con_password" value="<?php echo set_value('con_password'); ?>" />
  </p>        
  <p>
   <input type="submit" class="greenButton" value="Изпрати" />
  </p>
 <?php echo form_close(); ?>
</div><!--<div class="reg_form">-->    
</div><!--<div id="content">--> 

And this model:

public function add_user()
 {
  $data=array(
   'name'=>$this->input->post('user_name'),
   'email'=>$this->input->post('email_address'),
   'password'=>md5($this->input->post('password'))
   );
  $this->db->insert('users',$data);
 } 

Does anyone know where I could be wrong?
Thank’s advance!

NDB Session Class for Codeigniter - Version 2.0

Native Session makes good use of PHP’s native session handling abilities, but it does not allow the use of a database for session storage.
Saving user session data into database is more secure on any type of hosting (Shared ... ).
This library overwrites normal native sassion functions too save user data directly into database and gives us some extra functions over CI Session.

Problem with CI on subdomain and htaccess

2012-02-08T18:09:36+00:00

Hey,
I’m trying to set up a CI installation on a subdomain.
I’ve got some troubles with rewriting the url to the correct location :/
Here are more details: http://stackoverflow.com/questions/9197763/codeigniter-on-subdomain-and-htaccess

Admin for more than one site?

2012-02-08T05:40:20+00:00

Hope I am putting this question in the right place.

As some of you know I have been working on several websites for one client. Now I am building an admin system for them to handle all the site. I have seen several posts where you can switch config or database files by using the domain your on. I am not able to do that. The admin will be on one domain. All the sites are hosted on the same server so I am able to connect to all the databases from one domain.

They all have the same database structure just different data.

There are 4 total databases.

main <—holds the users and other internal stuff
site1
site2
site3

in my database.php file (config folder) I have set up 4 groups

default (main)
site1
site2
site3

Here is how it is working so far.

User goes to the admin, the default / main database loads.
During login the code checks to see what the last site was they were working on and sets a session var using set_userdata with that value.

Now logged in, the user sees a select menu with the current site (set in the session from the main db on login)

When they change the selector to a different site, i use ajax to change the session var and update the db. Doing so i use


$this->db->query();

and it is working fine.

The page reloads and the new selection shows and the session var is set to the new site / database.

Now on the pages where i pull information / edit / add etc.. i use the following code

$editdb = $this->session->userdata('editdb');
$CI =& get_instance();
$CI->$editdb = $this->load->database($editdb, TRUE);
$this->$editdb =& $CI->$editdb; 

Then to make the sql calls i use


$this->$editdb->query();

The issue comes when I want to use flash data. So say the user edits and item, well i want them to know the item was edited.
So i set flash data like so


$this->session->set_flashdata('msg','Update Success');

I then use the redirect with refresh set.

On the next page i check for the flashdata like so


If($this->session->flashdata('msg'))

But it never shows…

I am thinking it is because i have my sessions set to use the database. There are ways around it, i could use Cookies to pass the success or fail message but would like to keep everything consistent and well i seem to have no luck with the set cookie stuff in Codeigniter. My cookies never set…
If i use the php method of setcookie they work fine.

So I am guessing that what ever site is selected, that is the database the sessions are set to.

Any ideas on how to get my flash data to work across all the sites / databases?

Should i store the session localy and not in the database?

It is not a big cookie, userid(int), name, user type (int), logged in, selected site.

Thanks in advance.
