I'm trying to load view content page when url last segment matched. When click a link which get link in url like http://192.168.20.2/vtp/attendance/rawAttendance then load the rawAttendance view and when I click other link which last segment is getAttendance then it's also load the same same view not getAttendance. How do get this done?
$last = $this->uri->total_segments();
$lastSegment = $this->uri->segment($last);
if ($this->input->post("fromAjax")) {
if($lastSegment == "rawAttendance"){
$this->load->view('attendance/rawAttendance', $data);
}else if($lastSegment == "getAttendance"){
$this->load->view('attendance/getAttendance', $data);
}else {
}
}
CI has its inbuilt helper for knowing controller name and method name.
$classname = $this->router->fetch_class();
$methodname = $this->router->fetch_method();
if ($this->input->post("fromAjax")) {
if($classname == "attendance" && $methodname == "rawAttendance"){
$this->load->view('attendance/rawAttendance', $data);
}else if($classname == "attendance" && $methodname == "getAttendance"){
$this->load->view('attendance/getAttendance', $data);
} else {
}
}
CodeIgniter is a basic MVC framework - so everything starts with the controller. From the code you've written, I assume you already have your routes, etc configured to point at the method you've placed in your question.
You can simplify things quite a bit from the way you have them. Using the CI helper for controller/method is a bit helpful, but I think you're looking for something a little more elastic in your approach to dynamically load a view based on your last URI segment.
Try something like this:
// Get your last URI segment
$last = $this->uri->total_segments();
$lastSegment = $this->uri->segment($last);
/**
* Do whatever logic you need to do to calculate your data
*/
// ...
/**
* Load the view
*/
$this->load->view( 'attendance/' . $lastSegment, $data );
This could probably be better architected using the CI routes capability though. For instance, if you have several view folders and view files within, it would be best practice to organize those and better cement your URI structures so that each URI segment plays a specific role:
CI routes.php
$route["vtp/(:any)/(:any)"] = "path_to_method";
Method
$dir = $this->uri->segment(2);
$view = $this->uri->segment(3);
$this->load->view( $dir . "/" . $view, $data );

I'm using Codeigniter. Basically what I want is to remove the Controller name (Home) from the url.
Those urls look like:
http://localhost/mechanicly/Home
http://localhost/mechanicly/Home/about
http://localhost/mechanicly/Home/contactus
now there are two ways I can remove the Home controller:
static definition of every url inside route:
$route['about'] = "Home/about";
$route['contactus'] = "Home/contactus";
I can use call backs in routes in Codeigniter:
$route['(.+)'] = function ( $param ) {
if( strpos( $param, "Admin" ) !== false ) {
echo $param;
return "Admin/".$param;
}
else{
echo $param;
return "Home/".$param;
}
};
this logic is much better as it is generic and I don't have to create new routes every time for new method inside the controller.
It is working fine for the client controller which is Home but I have another controller named as Admin and I want to redirect Admin requests to the Admin controller and Home request to the Home Controller.
Why does above code work fine for the Home controller but returns
not found
when I validate for the Admin controller?
I am using CI version 3.x
If you really want to get crazy, you could parse the methods from the controller file and programatically create the "static" approach.
Pseudo code here
$controller_file_contents = file_get_contents('path/to/controller.php');
$controller_methods = function_that_parses_methods_from_file($controller_file_contents);
foreach ($controller_methods as $controller_method) {
$route[$controller_method] = "Home/" . $controller_method;
}
How function_that_parses_methods_from_file works is probably gonna involve a regex, something like function \w+. If you go with this approach, try to keep the controller as small as possible by offloading as much logic as possible into models, which is often a good idea anyways. That way the performance impact in the router is as small as possible.
Alternatively, you may be able to parse the controller using get_class_methods if you can figure out how to load the controller into memory inside the router without conflicting when you need to load the controller using the router or causing too much performance issues.
Pretty goofy, but every method you create in that controller will automatically create a route.
you can create your menu(url´s) from db like
tbl_menu tbl_level
---------- -------------
id id
fk_level level
name dateUP
dateUP active
active
In your controllers you need to call the correct menu by session or wherever you want
then you can has this in your route.php
$route['(.+)'] = 'int_rout/routing/' . json_encode($1);
in your controller Int_rout.php
public function routing ( $param ) {
$routing = json_decode($param);
$routing = explode('/', $routing);
//$menu -> get menu from model
foreach($menu as $item){
if($routing[0] === $item->name){
//$level -> get level from model
$redirect = $level->level;
}
}
//the final redirect will be like
//admin/user or admin/user/12
//public/us
$params = ( empty($routing[1])) ? '' : '/' . $routing[1];
redirect($redirect . '/' . $routing[0] . $params, 'refresh');
}
I am trying to load a page dynamically based on the database results however I have no idea how to implement this into codeigniter.
I have got a controller:
function history()
{
//here is code that gets all rows in database where uid = myid
}
Now in the view for this controller I would like to have a link for each of these rows that will open say website.com/page/history?fid=myuniquestring however where I am getting is stuck is how exactly I can load up this page and have the controller get the string. And then do a database query and load a different view if the string exsists, and also retrieve that string.
So something like:
function history$somestring()
{
if($somestring){
//I will load a different view and pass $somestring into it
} else {
//here is code that gets all rows in database where uid = myid
}
}
What I don't understand is how I can detect if $somestring is at the end of the url for this controller and then be able to work with it if it exists.
Any help/advice greatly appreciated.
For example, if your url is :
http://base_url/controller/history/1
Say, 1 be the id, then you retrieve the id as follows:
function history(){
if( $this->uri->segment(3) ){ #if you get an id in the third segment of the url
// load your page here
$id = $this->uri->segment(3); #get the id from the url and load the page
}else{
//here is code that gets all rows in database where uid = myid and load the listing view
}
}
You should generate urls like website.com/page/history/myuniquestring and then declare controller action as:
function history($somestring)
{
if($somestring){
//I will load a different view and pass $somestring into it
} else {
//here is code that gets all rows in database where uid = myid
}
}
There are a lot of ways you can just expect this from your URI segments, I'm going to give a very generic example. Below, we have a controller function that takes two optional arguments from the given URI, a string, and an ID:
public function history($string = NULL, $uid = NULL)
{
$viewData = array('uid' => NULL, 'string' => NULL);
$viewName = 'default';
if ($string !== NULL) {
$vieData['string'] = $string;
$viewName = 'test_one';
}
if ($uid !== NULL) {
$viewData['uid'] = $uid;
}
$this->load->view($viewName, $viewData);
}
The actual URL would be something like:
example.com/history/somestring/123
You then know clearly both in your controller and view which, if any were set (perhaps you need to load a model and do a query if a string is passed, etc.
You could also do this in an if / else if / else block if that made more sense, I couldn't quite tell what you were trying to put together from your example. Just be careful to deal with none, one or both values being passed.
The more efficient version of that function is:
public function history($string = NULL, $uid = NULL)
{
if ($string !== NULL):
$viewName = 'test_one';
// load a model? do a query?
else:
$viewName = 'default';
endif;
// Make sure to also deal with neither being set - this is just example code
$this->load->view($viewName, array('string' => $string, 'uid' => $uid));
}
The expanded version just does a simpler job at illustrating how segments work. You can also examine the given URI directly using the CI URI Class (segment() being the most common method). Using that to see if a given segment was passed, you don't have to set default arguments in the controller method.
As I said, a bunch of ways of going about it :)
I have a base controller (base) which all other controllers extend from.
Anything placed here will override other controllers, the redirects will be here.
URLs example:
http://domain.com/controllerone/function
http://domain.com/controllertwo/function
http://domain.com/controllerthree/function
Using the code below. will give me the controller name
$this->uri->segment(1);
Each of the above controllers need to be redirected to separate URLs, but the funcation part should not change:
http://domain.com/newcontrollerone/function
http://domain.com/newcontrollertwo/function
http://domain.com/newcontrollerthree/function
In my base controller i want the following logic:
$controller_name = $this->uri->segment(1);
if($controller_name === 'controllerone'){
// replace the controller name with new one and redirect, how ?
}else if($controller_name === 'controllertwo'){
// replace the controller name with new one and redirect, how ?
}else{
// continue as normal
}
i was thinking i should use redirect() function and str_replace(), but dont know how efficient these would be. Ideally i do not want to use the Routing class.
thanks.
try
header("Location:".base_url("newcontroller/".$this->uri->segment(2)));
Simple Solution using segment_array:
$segs = $this->uri->segment_array();
if($segs[1] === 'controllerone'){
$segs[1] = "newcontroller";
redirect($segs);
}else if($segs[1] === 'controllertwo'){
$segs[1] = "newcontroller2";
redirect($segs);
}else{
// continue as normal
}
CodeIgniter's URI Routing, should be able to help in this case. However, if you have a good reason not to use it, then this solution may help.
The potential redirects are in an array, where the key is the controller name being looked for in the URL and the value is the name of the controller to redirect to. This may not be the most efficient but I think it should be easier to manage and read than a potentially very long if-then-else statement.
//Get the controller name from the URL
$controller_name = $this->uri->segment(1);
//Alternative: $controller_name = $this->router->fetch_class();
//List of redirects
$redirects = array(
"controllerone" => "newcontrollerone",
"controllertwo" => "newcontrollertwo",
//...add more redirects here
);
//If a redirect exists for the controller
if (array_key_exists($controller_name, $redirects))
{
//Controller to redirect to
$redirect_controller = $redirects[$controller_name];
//Create string to pass to redirect
$redirect_segments = '/'
. $redirect_controller
. substr($this->uri->uri_string(), strlen($controller_name)); //Function, parameters etc. to append (removes the original controller name)
redirect($redirect_segments, 'refresh');
}
else
{
//Do what you want...
}
I'm not sure if I'm approaching this fundamentally wrong or if I'm just missing something.
I have a controller and within it an index function that is, obviously, the default loaded when that controller is called:
function index($showMessage = false) {
$currentEmployee = $this->getCurrentEmployee();
$data['currentEmp'] = $currentEmployee;
$data['callList'] = $currentEmployee->getDirectReports();
$data['showMessage'] = $showMessage;
$this->load->view('main', $data);
}
I have another function within that controller that does a bulk update. After the updates are complete, I want the original page to show again with the message showing, so I tried this:
/**
* Will save all employee information and return to the call sheet page
*/
function bulkSave() {
//update each employee
for ($x = 0; $x < sizeof($_POST['id']); $x++) {
$success = Employee::updateEmployeeManualData($_POST['id'][$x], $_POST['ext'][$x], $_POST['pager'][$x], $_POST['cell'][$x], $_POST['other'][$x], $_POST['notes'][$x]);
}
$this->index($success);
}
What is happening is that the original page is accessed using:
localhost/myApp/myController
after the bulk update it is showing as:
localhost/myApp/myController/bulkSave
when I really want it to show the url as the index page again, meaning that the user never really sees the /bulkSave portion of the URL. This would also mean that if the user were to refresh the page it would call the index() function in the controller and not the bulkSave() function.
Thanks in advance.
Is this possible?
You are calling your index() funciton directly, within bulkUpdate() hence the uri does not change back to index because you are not making a new server request, you are just navigating within your controller class.
I usually use the same Controller function for tasks like this, directing traffic based on whether or not $_POST data has been passed or not like this...
function index() {
if($_POST) {
//process posted data
for ($x = 0; $x < sizeof($_POST['id']); $x++) {
$data['showMessage'] = Employee::updateEmployeeManualData($_POST['id'][$x], $_POST['ext'][$x], $_POST['pager'][$x], $_POST['cell'][$x], $_POST['other'][$x], $_POST['notes'][$x]);
}
}
else {
//show page normally
$data['showMessage'] = FALSE;
}
//continue to load page
$currentEmployee = $this->getCurrentEmployee();
$data['currentEmp'] = $currentEmployee;
$data['callList'] = $currentEmployee->getDirectReports();
$this->load->view('main', $data);
}
Then if it is a form that you are submitting, just point the form at itself in your view like this...
<?= form_open($this->uri->uri_string()) ?>
This points the form back at index, and because you are posting form data via $_POST it will process the data.
I usually do a redirect to the previous page as it prevent users to refresh (and submit twice) their data.
You can use the redirect() helper function of CI.

I would like to create a custom CMS within Codeigniter, and I need a mechanism to route general pages to a default controller - for instance:
mydomain.com/about
mydomain.com/services/maintenance
These would be routed through my pagehandler controller. The default routing behaviour in Codeigniter is of course to route to a matching controller and method, so with the above examples it would require an About controller and a Services controller. This is obviously not a practical or even sensible approach.
I've seen the following solution to place in routes.php:
$route['^(?!admin|products).*'] = "pagehandler/$0";
But this poses it's own problems I believe. For example, it simply looks for "products" in the request uri and if found routes to the Products controller - but what if we have services/products as a CMS page? Does this not then get routed to the products controller?
Is there a perfect approach to this? I don't wish to have a routing where all CMS content is prefixed with the controller name, but I also need to be able to generically override the routing for other controllers.
If you use CodeIgniter 2.0 (which has been stable enough to use for months) then you can use:
$route['404_override'] = 'pages';
This will send anything that isn't a controller, method or valid route to your pages controller. Then you can use whatever PHP you like to either show the page or show a much nicer 404 page.
Read me guide explaining how you upgrade to CodeIgniter 2.0. Also, you might be interested in using an existing CMS such as PyroCMS which is now nearing the final v1.0 and has a massive following.
You are in luck. I am developing a CMS myself and it took me ages to find a viable solution to this. Let me explain myself to make sure that we are on the same page here, but I am fairly certain that we area.
Your URLS can be formatted the following ways:
http://www.mydomain.com/about - a top level page with no category
http://www.mydomain.com/services/maintenance - a page with a parent category
http://www.mydomain.com/services/maintenace/server-maintenance - a page with a category and sub category.
In my pages controller I am using the _remap function that basically captures all requests to your controllers and lets you do what you want with them.
Here is my code, commented for your convenience:
<?php
class Pages extends Controller {
// Captures all calls to this controller
public function _remap()
{
// Get out URL segments
$segments = $this->uri->uri_string();
$segments = explode("/", $segments);
// Remove blank segments from array
foreach($segments as $key => $value) {
if($value == "" || $value == "NULL") {
unset($segments[$key]);
}
}
// Store our newly filtered array segments
$segments = array_values($segments);
// Works out what segments we have
switch (count($segments))
{
// We have a category/subcategory/page-name
case 3:
list($cat, $subcat, $page_name) = $segments;
break;
// We have a category/page-name
case 2:
list($cat, $page_name) = $segments;
$subcat = NULL;
break;
// We just have a page name, no categories. So /page-name
default:
list($page_name) = $segments;
$cat = $subcat = NULL;
break;
}
if ($cat == '' && $subcat == '') {
$page = $this->mpages->fetch_page('', '', $page_name);
} else if ($cat != '' && $subcat == '') {
$page = $this->mpages->fetch_page($cat, '', $page_name);
} else if ($category != "" && $sub_category != "") {
$page = $this->mpages->fetch_page($cat, $subcat, $page_name);
}
// $page contains your page data, do with it what you wish.
}
?>
You of course would need to modify your page fetching model function accept 3 parameters and then pass in info depending on what page type you are viewing.
In your application/config/routes.php file simply put what specific URL's you would like to route and at the very bottom put this:
/* Admin routes, login routes etc here first */
$route['(:any)'] = "pages"; // Redirect all requests except for ones defined above to the pages controller.
Let me know if you need any more clarification or downloadable example code.
