Code Igniter - Get Last URI Segment

Sep 30, 2010

I'm tying to get the last URI segment in CI, however I don't know what the number for it will be, as parameters (an integer) will be appended as the user clicks links within the page. These are then used in a controller to pull relevant database records into the page via ajax.

How can I tell CI to get the last segment?

Something like:

$record_num = $this->uri->segment($last);


Strip Tags That's Are NOT In [code] [/code] Segment?

Sep 24, 2009

I'm trying to find a way to strip tags from a user-inputted string except from tags that are wrapped in the [code] [/code] BB style tag.

For example, a user may enter this:


What I would like is the "hacked" alert to be removed, but not the "Hello" alert.

I would like to remove ALL tags (php, html, css, js) outside of the [code] but allow anything within them.

So far, I've got the following code to do the reverse of what I would like:

Javascript - Beginner - Pass Variable From One Code Segment To Another ?

Jun 6, 2010

I have index.php which uploads a file to server and sets several PHP variables (like $target_folder_and_file_name).

index.php also has the following line (it was originally index.html):

<script language="JavaScript" src="main.js.php"></script>

After index.php returned to the browser, the browsers asks for main.js.php from the server (right?).

Can I access somehow $target_folder_and_file_name from the PHP code in main.js.php ?

Execute Code Segment Only If Loop Reaches Its Last Cycle

Oct 30, 2009

Where is the most efficient position for a code block, which shall only execute, if a loop has reached its end, without having previously been aborted (via break or return)? Provided: "Some Code X" is always the same, only at different Code Segment Positions 1 and 2. I assume: 2 will be executed with the same reliability as 1. Am I wrong I know: 2 is obviously more efficient, as it is only called once after the loop ran $limit times, compared to 1, whose enclosing if-condition is called $limit times, and if once true, the code itself is called. Thus the efficiency difference is if-condition queried $limit times. Hence I conclude: To prefer using Code Segment 2 rather than Code Segment 1, unless my assumption is wrong!

Using Lightbox With Code Igniter?

Jun 22, 2010

I'm trying to use Lightbox with my CodeIgniter application. Lightbox says to put the following in the head tag:

<script type="text/javascript" src="js/prototype.js"></script>
<script type="text/javascript" src="js/scriptaculous.js?load=effects,builder"></script>
<script type="text/javascript" src="js/lightbox.js"></script>
<link rel="stylesheet" href="css/lightbox.css" type="text/css" media="screen" />


This displays the thumbnail version, and then when clicked I want it to go to the lightbox, but now it goes to a new tab with the large image.

I've used lightbox before and have always gotten it to work, I'm not really sure what the problem is now, and I tried moving the files all around to different spots but nothing worked.

Jumping Controllers In Code Igniter

Apr 27, 2011

I am wanting to have a form of dynamic routing.

Basically I want to catch the 404 (done through routes.php 404_override).

This is easy enough.

But then what I want to do is run through a series of checks.

e.g pay no attention to the fact the is_xxx functions are not coming from anywhere

$what = $this->uri->segment(1);
//now I want to route this to the profile controller and call the display function like so
//display('vanity', $what);


How would I go about re-routing to the other controllers once the decision has been made?

Logout Feature In Code Igniter?

Apr 4, 2011

I started using codeigniter for my project. I have user authentication system for my website. I have seen the videos from nettuts for the login information. I am confused why the logout is not working properly. I have the following logout function in my login controller.

function logout() {

If I click on the logout button I am redirecting the user to the main page. But after redirecting the user to the main page, if click on the back button on the browser I will see the logoff and my name on the top of the page. I need some help on where I am going wrong or is there any important piece of code I am missing in my controller I think I found the solution. I should append the following code into the appropriate controller

$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0");
$this->output->set_header("Pragma: no-cache");

Code Igniter [did Not Found Page Created]

My first page is leave_app.php. In this page I put a link to apply leave, using the normal code:

However the link didn't display as I had wished for.

"The requested URL /ci/add.php was not found on this server." and the link in the browser leads to this "url".

I don't know why the server didn't find the page. I already made add.php page, also add at the leave_app controller the function add().

In the config.php file I put $config['index_page'] = '';

I have asked around but no one can help. I have already surfed around, but still don't know how to solve.

Having Code Igniter URI Segments For Multiple Variables?

Feb 16, 2010

I'm writing an app that allows you to filter database results based on Location and Category. If someone was to search for Liverpool under the Golf category the URI would be /index.php/search/Liverpool/Golf. Should someone want to search by Location but not category, they would be sent to /index.php/search/Liverpool However, should someone want to filter only by category they would be unable to use /index.php/search/Golf because that would be caught by the location search.

Is there a best practice way to have /index.php/search/Golf be recognised? Some best practice as to what else to add to the URI to make these two queries distinct? /index.php/search/category/Golf perhaps? Though that is beginning to show characteristics of /index.php?search&category=Golf which is exactly what I'm trying to avoid.

Add Dynamic Content To A Template In Code Igniter?

Mar 29, 2011

I am trying a HTML/CSS file to convert to a template. I asked for help but I didn't receive any suggestions in that post yet I tried to figure out a way to create a template. I am having few glitches in doing that. My controller has main.php file which is the main page of the website, and I have register where the header, footer, and rest remain same except that main content changes when the page loads.

I have the following template in the views folder:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

This is the div tag which would be changing when a site loads. In my template I have included <

<?= $flashcontent ?> <?= $resource ?> and <?= registerForm ?>

The flashcontent and resources are supposed to be in the main page and registerForm is supposed to be shown when I click on register in the main page. I have been reading the template user guide in the code igniter but I am unable to understand how to make this dynamic.This is the template.php in config folder.

$template['active_group'] = 'default';
$template['default']['template'] = 'template.php';
$template['default']['regions'] = array([code]....

Can't Use Xdebug To Debug Code Igniter App Using Netbeans 6.8 IDE

Jan 27, 2010

I can't use Xdebug to debug a application built with Code Igniter, but i can use it to debug any other PHP file as long it doesn't use the same Structure for url solving that Code Igniter uses.

Meaning: In a simple PHP file with no Code Igniter, when i use NetBeans debugging the browser goes to: http://localhost:86/index.php?XDEBUG_SESSION_START=netbeans-xdebug

Since no Code Igniter or other framework as been used, NetBeans can actually debug the PHP.

But when using Code Igniter when hit the debug button in NetBeans, and the browser goes to:


the root index.php where all happens in Code Igniter no luck, instead i get the standard CodeIgniter "404 Page not Found".

My guess its that due to the structure Segments that Code Igniter uses for url solving, xdebug can't debug nothing.

Example: [URL]

How can i make xdebug work with Code Igniter?

Codeigniter - Code Igniter - Unserialize An Array?

Jun 6, 2011

I have previously serialized an array in PHP and submitted it to a database. Now, in my model in Code Igniter, I want to unserialize that data but I'm not sure how to reference it. Here's my code:

function get_selected_member($member = null){
if($member != NULL){
$this->db->where('id', $member); //conditions
$query = $this->db->get('members'); //db name
$member_result = $query->row();


So member_result is an object containing all of values for the table row matching the member a user selected from a form. Within this object, one of the column values is member_dep - but referencing it as $member_result[$member_result->member_dep] does not work. How do I refer to this. I basically want to pull that value out, declare it as a variable, call unserialize(), and then put it back into place so that it can be read by JQuery / HTML as an array.

Simple Code Igniter Sidebar Implementation?

Jun 10, 2011

I posted a thread a few days back but it didnâ take the direction I was looking for, so I will try again and fingers cross explain a little better.I have a list of controllers.. Home, League, Forum as so on. Once the controller has its data it calls down to a view named template which in turn calls the default header, footer, content and sidebar views. (The content variable is set by the controller).So far so good, this works great until I realise the need the sidebar data to be dynamic instead of its current static state.. Now as the site grows larger I would prefer not to have to specify the data that gets called for the sidebar each time.I would prefer to set a variable in the controller that loads possibly, I see this being done in the template view, however I know controllers can not be called in view, so I am stuck.

I am trying to get Uploadify working with code igniter however am having the same problem as everyone with a new session being created for "ShockWave Flash" instead of picking up the already created session.

$config['sess_expire_on_close'] = FALSE;
$config['sess_encrypt_cookie'] = TRUE;
$config['sess_use_database'] = TRUE;
$config['sess_table_name'] = 'sessions';
$config['sess_match_ip'] = TRUE;
