Autocomplete on CodeIgniter 1.5.4

Posted by: El Forum - 04-11-2008, 02:51 PM - Replies (7)

	[eluser]mexor[/eluser] I tried this http://video.derekallard.com/ Auto completer on CodeIgniter 1.5.4 but couldn't get it to work. Nothing shows up in the autocomplete, and no functions show up in the DIV after searching. I've asked a few people who have used codeIgniter a lot and they couldn't get it to work either. Anyone have any suggestions on what would make it work? Thanks Dave

I need some help with IPBSDK

Posted by: El Forum - 04-11-2008, 12:18 PM - No Replies

[eluser]CrazeD[/eluser]
Hi, new here...

Okay so, I'm trying to use IPBSDK with Codeigniter. If you aren't familiar with IPBSDK, it is a very useful class for integrating Invision Power Boards into your main website. It includes login/logout functions, getting info... tons of useful stuff.

Now, I've made it work, but in a troublesome way. I have a header and footer PHP files for my template, then I just slip in the current page in the middle. My controller for any given page looks like so:

Code:
class Test extends Controller {

    function index() {

        $this->load->view('header');

        $this->load->view('test');

        $this->load->view('footer');

    }

}

Now, I couldn't get the SDK to load with the $this->load->library function, so I just included the class on the main index.php file, which works fine.

So, my header and footer files both have to call the IPBSDK class, like so:

Code:
$SDK = new IPBSDK;

I have that at the beginning of both files. Most of my pages also require this, so I have to have it at the beginning of those pages as well.

Most of the SDK functions work great, except login/logout functions. It is because I called the IPBSDK class in the header, footer, and current page files. If I do this it works:

Code:
class Test extends Controller {

    function index() {

        $SDK = new IPBSDK;

        $data['SDK'] = $SDK;

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

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

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

    }

}

Now, everything works.

However I don't want to have to do that for every controller, is there anyway I can call this class from one location and have it available on all pages?

Thanks.

Strange callback validation error for an array

Posted by: El Forum - 04-11-2008, 11:16 AM - Replies (1)

[eluser]Isos[/eluser]
In a user profile, user is asked to check at least 5 checkboxes out of 30.
The checkboxes are named as discplines[] as following:

Code:
&lt;input type="checkbox" name="disciplines[]" value="&lt;?$discipline-&gt;id;?&gt;" />

It means $_POST['disciplines'] is an array of disciplines IDs
So I created a callback functions as following:

Code:
function _check_if_more_than_five($str){

    if (count($str) > 5){

         $this->validation->set_message("_check_if_more_than_five","You cannot check more than five disciplines");

            return false;

        } else { 

            return true;

        }

    }

The good thing about this is that it works, but the bugging ugly thing is that I get this error at the top of the page:

A PHP Error was encountered

Severity: Notice

Message: Array to string conversion

Filename: libraries/Validation.php

Line Number: 709

Where Line Number: 709 in libraries/Validation.php is as following:

Code:
return str_replace(array("'", '"', '<', '>'), array("'", "&quot;", '&lt;', '&gt;'), stripslashes($data));

The whole function is as following:

Code:
/**

     * Prep data for form

     *

     * This function allows HTML to be safely shown in a form.

     * Special characters are converted.

     *

     * @access    public

     * @param    string

     * @return    string

     */

    function prep_for_form($data = '')

    {

        if (is_array($data))

        {

            foreach ($data as $key => $val)

            {

                $data[$key] = $this->prep_for_form($val);

            }

        }

        if ($this->_safe_form_data == FALSE OR $data == '')

        {

            return $data;

        }

        return str_replace(array("'", '"', '<', '>'), array("'", "&quot;", '&lt;', '&gt;'), stripslashes($data));

    }

I am trying to figure out what's wrong and how I may solve this. But, when it comes to manipulating a ci script to solve a problem I tend to consult in here.

Any help will be appreciated.

Thanks.

Problem with a db query

[eluser]Unknown[/eluser]
I have a problem with one query.

I have this code:

Code:
$this->db->select("f.*, (SELECT GROUP_CONCAT (CONCAT(p.nome, ' ', p.cognome) SEPARATOR ', ') 

                         FROM professionisti p 

                                                 WHERE p.id IN (SELECT r.id_professionista FROM registi r WHERE r.id_film = f.id)

                                                ) AS regista", FALSE);

$this->db->from($this->tables['film'] . ' f');

$this->db->where("f.pagina_html = '" . $film . "'");

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

return $sql->row();

but the above code return me the following error:

Quote:An Error Was Encountered

Error Number: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SEPARATOR ', ') FROM professionisti p ' at line 1

SELECT f.*, (SELECT GROUP_CONCAT (CONCAT(p.nome, ' ', p.cognome) SEPARATOR ', ') FROM professionisti p WHERE p.id IN (SELECT r.id_professionista FROM registi r WHERE r.id_film = f.id) ) AS regista FROM (`film` f) WHERE f.pagina_html = 'grindhouse_us_version'

the query reported in the error message don't have problem in phpmyadmin.

I also tried with the following code:

Code:
$sql = "SELECT f.*, (SELECT GROUP_CONCAT (CONCAT(p.nome, ' ', p.cognome) SEPARATOR ', ')

FROM professionisti p 

WHERE p.id IN (SELECT r.id_professionista FROM registi r WHERE r.id_film = f.id)

) AS regista

FROM film f

WHERE f.pagina_html = '" . $film . "'";

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

but return me the same error.

Where is the problem?

PS: excuse me for my english. I hope you can understand what i wrote.

search with pagination: POST first, then GET?

Posted by: El Forum - 04-11-2008, 09:38 AM - Replies (1)

[eluser]Unknown[/eluser]
First of all, thanks to all the contributors to this forum
I've found it invaluable in my first CI project!

Ok, so I have a search page with pagination running fine

http://www.mysite.com/jobs/search/css:html/london
http://www.mysite.com/jobs/search/css:html/london/4
etc;

I might change it to
http://www.mysite.com/jobs/search/for/cs...n/offset/4
and then use $this->uri->uri_to_assoc(n)
if it helps my problem below.

But what I'm not sure about is when I want to call this URL
from a simple search form on the same page.

Should I use a GET method on the form and then try and turn
http://www.mysite.com/jobs/search?for=cs...n&offset=4
into
http://www.mysite.com/jobs/search/for/cs...n/offset/4
using htaccess or the routing feature of CI?

or should I use
some logic in the controller to check if it was a POST or GET
it's further comlicated because I would like to use the validation library to check if the fields are empty.

Any advice greatly appreciated,
Thanks.

This is the method in my controller

Code:
function search()

   {

    $this->output->enable_profiler(TRUE);

       $segs = $this->uri->segment_array();

    $search_txt = $this->uri->segment(3, 'all');

    $search_terms = explode(":",$this->uri->segment(3));    

    $search_location = $this->uri->segment(4, 'any');

    $search_offset = $this->uri->segment(5, 0);

        $this->load->helper(array('form', 'url'));

        $this->load->library('validation');

        $fields['for'] = 'for';

        $fields['location'] = 'location';

        $this->validation->set_fields($fields);

        $rules['for'] = 'required';

        $this->validation->set_rules($rules);

        $data['page'] = 'search';

        $data['header'] = $this->load->view('includes/header', $data, true);

    // pagination

    $this->load->library('pagination');

    $config['base_url'] = base_url().$this->uri->slash_segment(1, 'leading').$this->uri->slash_segment(2, 'both').$search_txt.'/'.$search_location.'/'; // cahnge to url

    $config['total_rows'] = $this->db->count_all('jobs');

    $config['per_page'] = '2';

    $config['full_tag_open'] = '<p>';

    $config['full_tag_close'] = '</p>';

    $config['num_links'] = 2;

    $config['uri_segment'] = $this->uri->total_segments();

    $this->pagination->initialize($config);

    // load jobs model

    $this->load->model('jobs_model', '', TRUE);

    $data['results'] = $this->jobs_model->get_jobs($search_terms,$config['per_page'],$search_offset);

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

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

  }

[SOLVED] Upload 2 files with diferent configuration

Posted by: El Forum - 04-11-2008, 09:36 AM - Replies (2)

[eluser]Lagarto[/eluser]
I'm trying to upload (using file upload library) 2 files from the same form, but each of this files have a diferent "config", i've tested this code and it seems that only take the first config/library loading.

Code:
$config['upload_path'] = 'public/uploaded';

$config['allowed_types'] = 'gif|jpg|png';

$config['max_size']    = '10000';

$config['max_width']  = '190';

$config['max_height']  = '125';

//$config['max_width']  = '600';

//$config['max_height']  = '395';                

$this->load->library('upload', $config);

if($this->upload->do_upload("img_thumb"))

{

    //agafo nom d'abans

    $data = $this->upload->data();

    $nom_thumb = $data['file_name'];

    $config['upload_path'] = 'public/uploaded';

    $config['allowed_types'] = 'gif|jpg|png|swf';

    $config['max_size']    = '10000';

    $config['max_width']  = '600';

    $config['max_height']  = '395';

    $this->load->library('upload', $config);

    if($this->upload->do_upload("img_gran"))

    {

        //agafo nom d'abans

        $data = $this->upload->data();

        $nom_gran = $data['file_name'];

        //insert

        $nombre = $_POST['nombre'];

        $fecha = time();

        $idioma=1;

        $texto = $_POST['texto'];

        $insert = array($nombre, $fecha, $idioma, $texto, $nom_thumb, $nom_gran);

        $this->db->query("INSERT INTO `realisations` (`nombre`, `fecha`, `idioma`, `texto`, `img_thumb`, `img_gran`) VALUES (?, ?, ?, ?, ?, ?)", $insert);

        redirect('realisations/index/created_ok');

    }    

    else

    {

        redirect('realisations/add/error_ok/2');

        //echo $this->upload->display_errors();

    }

}    

else

{

    redirect('realisations/add/error_ok/1');

    //echo "error 1";

    //echo $this->upload->display_errors();

}

Am I doing something wrong? Bug spotted?

Thanks! Big Grin

How to retrieve database error from CodeIgniter

Posted by: El Forum - 04-11-2008, 08:09 AM - Replies (18)

	[eluser]Erikk[/eluser] Hello, How do you actually retrieve database error when inserting data for example ? db_debug would be turned off so you can handle errors your way - for example if you need so send back the error to an ajax request. What's the equivalent of say mysql_error() ? Thankx.

Extend Exceptions Class for DB Errors

Posted by: El Forum - 04-11-2008, 07:41 AM - Replies (1)

[eluser]Pascal Kriete[/eluser]
I've already extended the Exceptions class for php, general, and 404 errors. So I figured I could just add db errors as well.

I was wrong.
As it is right now the code looks like this:

Code:
function display_error($error = '', $swap = '', $native = FALSE)

{

//    $LANG = new CI_Lang();

    $LANG = new CI_Language();

    $LANG->load('db');

    $heading = 'Database Error';

    if ($native == TRUE)

    {

        $message = $error;

    }

    else

    {

        $message = ( ! is_array($error)) ? array(str_replace('%s', $swap, $LANG->line($error))) : $error;

    }

    if ( ! class_exists('CI_Exceptions'))

    {

//        include(BASEPATH.'core/Exceptions'.EXT);

        include(BASEPATH.'libraries/Exceptions'.EXT);

    }

    $error = new CI_Exceptions();

    echo $error->show_error('An Error Was Encountered', $message, 'error_db');

    exit;

}

What the?

The biggest issue here is that it creates a new Exceptions object. Why?
What's wrong with just calling the show_error method declared in common.php?

Also, why does it set $header if it's not used?

Should be something more like this:

Code:
function display_error($error = '', $swap = '', $native = FALSE)

{

    $LANG =& load_class('Language');

    $LANG->load('db');

    $heading = 'Database Error';

    if ($native == TRUE)

    {

        $message = $error;

    }

    else

    {

        $message = ( ! is_array($error)) ? array(str_replace('%s', $swap, $LANG->line($error))) : $error;

    }

    show_error($heading, $message, 'error_db');

}

EDIT: Ok, doesn't quite work like that because show_error only takes on argument. The point remains however.

Ajax

Posted by: El Forum - 04-11-2008, 06:57 AM - Replies (1)

[eluser]Unknown[/eluser]
Hi.
I am new to web programming (read my intro)
But i know ill have to use Ajax technology to get the result i want but im really lost on that point.
Could anyone point me out on a really straight to the point walkthrough.
Im sure there is plenty on the net but i could'nt find one.
Basicly waht i need to be ablle to get accomplished is:

1- refresh an html table (or somekthing else if necessary) on a button click from information from a Mysql database.

2- Make a call to a php function to process some information in an html page to update the database.

i think that ajax could be a solution but i am not sure. (any other way to do it is great to)
but the main point is to avoid redirect and full page reloading.

But i am aware that i may be completly off track but i hope not.

More detaille for point 1:

I have an html table with time entry for employe. this page allow for modification and adding new entry.
I have the js_calendar plugin and when i select a datae on the calendar and click refresh i want to refresh the table for the time entry of that day.

If i get to do that i should be able to answer point 2 myself.
