    $config['total_rows'] = 4;
    $config['per_page'] = 1;
    $this->pagination->initialize($config);
    $this->load->model('Gallery_model');
    $data['products'] = $this->Gallery_model->show_products();
    $data['images'] = $this->Gallery_model->get_images();
    $this->load->view('show_products', $data);
  }

<div id="blank_gallery">Product Description</div>

upload

2012-02-13T03:28:13+00:00

hi, i am newbie in codeigniter.

i want to create an upload page where user can upload files to the server (it is only a testing for me so it will run on localhost), and i want to make sure that the file is not vulnerable. is it enough to use the upload class or should i integrate it with antivirus too? if i should make an integration, how to do it?

thank you.

question about session

2012-02-13T02:20:05+00:00

I save user login ID in session. And when user logout, I update user table in postgresql database with logout time and user ID from session data. I found sometimes logout time on user table wasn’t updated. I wonder the user ID in session data has already gone(expired) before user logout. Does session expire by some exception rather than settings on


$config['sess_expiration']

? Because the default value is long enough, 7200.

CodeIgniter suitable for my project?

2012-02-11T14:31:28+00:00

Hi everyone,

I have been presented with a project to update an old and dated website; www.rccdams.co.uk

It was originally built using PHP 4 and a variety of static html templates.

My question is this:
Since it’s not a complex site (the most complex it gets is the dam database search) is it worth reworking the site in CodeIgniter? Will there be any benefit?

I have to add that although I’m well versed in designing and building HTML sites and have used WordPress and Concrete5 in the past, I’d classify myself as a PHP novice and have never used CodeIgniter before.

There is additional functionality that the site owner has requested (apart from dragging it into this century!) and I thought I could do this using add-ons.

The site has no content management system to speak of, so I was thinking of using PyroCMS.

Anyway, any help, advice, information would be gratefully received.

Many thanks,
Tony.

cannot overwrite URI method _detect_uri

2012-02-10T11:28:00+00:00

My situation is a bit complicated, i’ll try to explain.
I use CI with query strings disabled, with the default URI system based on segments.

Unfortunately sometimes i’m forced to accept query strings in my URL’s becuase google adwords manual tagging campaigns need that:

http://support.google.com/adwords/certification/bin/answer.py?hl=en&answer=156114

The solution to my problem is to tell apache rewrite th e url ignoring every query string (question mark at the end of the rule):

RewriteCond $1 !^(index\.php|assets|media|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1? [L]

The system works well almost everywhere, except if i have an URL without segments with a query string:

http://site.com/?string

in this case URI class take the query string as the first segment of URI, this happen becuase insisde function _detect_uri:

// This section ensures that even on servers that require the URI to be in the query string (Nginx) a correct
// URI is found, and also fixes the QUERY_STRING server var and $_GET array.

Ok, i had to deal with that, no problem, i just have to extend URI and rewrite tyhat function.
But i couldn’t because _detect_uri is declared as private and cannot be extended unless a change directly inside the system core URI class, that is something i prefer avoid, to keep my code portable between CI installation (and hopefully versions).

So the question is, what’s the point to have private functions inside CI libraries?
Why do not let the developer make all the changes he wants?
And, at last, why don’t you declare all non public functions as protected instead private?

thanks a lot

How to add FOREIGN KEY constraint when creating a table?

2012-02-10T07:59:39+00:00

I am trying to create a table which has a foreign key reference to another table. The table is being created by CodeIgnier. However, in


$this->dbforge->add_key()

I cannot see how would I indicate that this key should be a foreign key which references another key. How would I do that?

An experiment about translation special characters among html,php and mysql. Some problems.

2012-02-10T04:49:52+00:00

First I get data from html:


addslashes($POST['text'])

I found that mysql_real_escape_string() can work too, but there is no function to delete the ‘\’ that mysql_real_escape_string() add.
Second insert data into MYSQL.

The reverse action:
First get data from MYSQL:


stripslashes($result['text'])

Then show data in html,with htmlspecialchars() and nl2br().
Finally, I surprisingly see that some of data is shown with entity in html, not characters such as < > ’ “.However some of data is shown correctly.
That is why?
