I wanted to ask if there is any way i can get path of my view file in controller. For example
class welcome extends controller{
function __construct(){
parent::__construct();
}
function index(){
$this->load->view('welcome_message');
}
function test(){
$my_variable = $this->load->view('welcome_message','',TRUE);
}
function another_test(){
/// $path_to_view = ???;
/// echo $path_to_view;
}
}
i want to ask if there is any helper function to get this. The test method has variable containing the html contents in it. But i want to get path of view file???
I'm not sure if this is a proper way but you can try this, just create a helper file i.e. my_helper.php in your application/helper folder and paste following function in this helper file
function get_view_path($view_name)
{
$target_file=APPPATH.'views/'.$view_name.'.php';
if(file_exists($target_file)) return $target_file;
}
To use it you have to load the helper file first and then call the function with the name of the view as the function's argument
$this->load->helper('my_helper');
$path_to_view = get_view_path('welcome'); // Will return the path if welcome.php exists in the view folder.
You can auto load it using config.php's $autoload['helper'] = array('functions_helper');
It should be the constant:
VIEWPATH

In my project I have a controller call load and it has a fuction call search() that has a form, i want to submit this form in a child function of search() like this,,
localhost/ci/index.php/load/search
to
localhost/ci/index.php/load/search/something/
how can i do this after submission a form?
this is my contoller like
class Load extends CI_Controller {
function search() {
$this->load->view('search');
}
function something() {
$this->load->view('something');
}
}
This is not child function something()
You can define routes as per your requirements.
After search function call , you can use redirect() method, that will redirect to your route like 'base_url/controller/search/searchresult/'.
Routes.php
$route['Load/search/searchresult'] = 'Load/something';
Load Controller code :
class Load extends CI_Controller {
function search() {
$this->load->view('search');
// after form submission
redirect('Load/search/searchresult');
}
function something() {
$this->load->view('something');
}
}
This is not a child function of search function so you can call it like
localhost/ci/index.php/load/something/
Add this url to your form action and your form will be submitted to something() function
For clarity: localhost/ci/index.php/load/search/something/ does this...
Enters search() method of Load and provides something as a parameter e.g. search($param = 'something') (this is not correct syntax but just for show).
function search($term = null) {
if (is_null($term)) {
// user hasn't searched
} else {
// user searched for $term e.g. something
}
}
The only way you can achieve what you want is to either use the above somehow to your advantage knowing that /something will have to be the search parameter. Or you can use routing as another answerer suggested.
Can we call a controller and parsing any values or data to the controller from a method?
let's say that i have this method,
function loader(){
//some operations to call another controller
}
and from that method i want to call a controller named welcome.php wich is located in /application/controller
i'v tried this but it doesn't work
function loader(){
$open = new Welcome();
}
it says that Class Welcome not found
Sorry for my bad english
At first You have to include the file
include('welcome.php');
Then, create the object.
function loader(){
$open = new welcome();
//if you want to call a method in an object
$open->MyWelcomeMethod();
}
Makesure that your loader controller was extended to welcome controller.
Suppose controller welcome,my_controller are two controller and loader function in B then
class Welcome extends CI_Controller {
function my_fun() {}
}
then you can call my_fun() when you are entended from my_controller like
class My_Controller extends Welcome {
$open = $this->my_fun();
}
I put the following code in every controller under public function index(). As of now I have 3 controllers and it will increase until my website is finish. I need the code below in all pages (i.e. views).
$type = $this->input->post('type');
$checkin = $this->input->post('sd');
$checkout = $this->input->post('ed');
My question is where can I put the code above in just one location so it will be available on all pages (i.e. views) and avoid putting it in every controller.
If you have for example a main view file, and you need that code on every page, then I suggest you put in the main view file (view/index.php)
I think, with #KadekM answer, you should call a function every time in every controller, because you sad, you want this code in every controllers every function.
You can create your own controller (for example MY_cotroller) extending CI_controller, put shared code there, and then your three controllers should extend MY_controller.
You can then call it wherever you need it (or even put it to constructor if you need it everywhere).
Here's the sample I promised (assuming you have default codeigniter settings)
in core folder create file named MY_Controller.php
class MY_Controller extends CI_Controller{
protected $type;
protected $checkin;
protected $checkout;
protected $bar;
public function __construct()
{
parent::__construct();
$this->i_am_called_all_the_time();
}
private function i_am_called_all_the_time() {
$this->type = $this->input->post('type');
$this->checkin = $this->input->post('sd');
$this->checkout = $this->input->post('ed');
}
protected function only_for_some_controllers() {
$this->bar = $this->input->post('bar');
}
protected function i_am_shared_function_between_controllers() {
echo "Dont worry, be happy!";
}
}
then create your controller in controllers folder
class HelloWorld extends MY_Controller {
public function __construct() {
parent::__construct();
}
public function testMyStuff() {
// you can access parent's stuff (but only the one that was set), for example:
echo $this->type;
//echo $this->bar; // this will be empty, because we didn't set $this->bar
}
public function testSharedFunction() {
echo "some complex stuff";
$this->i_am_shared_function_between_controllers();
echo "some complex stuff";
}
}
then for example, another controller:
class HappyGuy extends MY_Controller {
public function __construct() {
parent::__construct();
$this->only_for_some_controllers(); // reads bar for every action
}
public function testMyStuff() {
// you can access parent's stuff here, for example:
echo $this->checkin;
echo $this->checkout;
echo $this->bar; // bar is also available here
}
public function anotherComplexFunction() {
echo "what is bar ?".$this->bar; // and here
echo "also shared stuff works here";
$this->i_am_shared_function_between_controllers();
}
}
Those are just examples, of course you won't echo stuff like this, but pass it to view etc., but I hope it's enough for illustration. Maybe someone comes with better design, but this is what I've used a few times.
id suggest , adding it to a library and then auto load the library so that each and every page on your website can access the same.
for autoloading reffer : autoload in codeigniter
i have this testing code which am working with ..
i have a module called ms and and another one called test
the test controller code is :
<?php
class Test extends MX_Controller {
public function __construct()
{
parent::__construct();
$this->template->title($this->config->item('site_name','app'));
}
public function index()
{
$this->template->build('index');
}
}
and the code inside ms is :
<?php
//ms module
class Msrofi extends MX_Controller {
public function __construct()
{
parent::__construct();
$this->template->title($this->config->item('site_name','app'));
}
public function index()
{
$t = Modules::run('test/test/index');
var_dump($t);
$this->template->build('index_message');
}
}
the problem is that the build function inside test is trying to find the index view file inside the ms views folder not the test views folder ..
i checked the $this->_module and it gave me the ms module name ..
any one know how to fix that ??
Since the test module is being called in the context of the ms one, $this->template->build() is looking for a view file in the ms module. The same way you can load models and libraries cross-module, you would have to do this for your view path as well:
class Test extends MX_Controller {
public function index()
{
// This path works only from the "test" module
// $this->template->build('index');
// This path works from any module
$this->template->build('test/index');
}
}
It's a little annoying maybe to have to explicitly call the module path in the module itself, but cross-module dependency defeat some of the goals of modularity in the first place.
A quick aside: Modules::run() output not returned, but directly echoed, so you can't assign it to a variable or print_r/var_dump it without using an output buffer:
ob_start();
Modules::run('test/test/index');
$t = ob_get_clean();
var_dump($t);
You can try to change the module.php the run method
The following example is I have to use the fix solution：
Open the third_party/MX/Modules.php
Near 75 lines to find
$buffer = ob_get_clean();
Increase in its following：
if($output === NULL && $buffer === ''){
$output = CI::$APP->output->get_output();
}
At this time, it should be able to work properly...
I have two controllers a and b.
I would like to call a method of controller a from a method of controller b.
Could anyone help explain how I can achieve this?
This is not supported behavior of the MVC System. If you want to execute an action of another controller you just redirect the user to the page you want (i.e. the controller function that consumes the url).
If you want common functionality, you should build a library to be used in the two different controllers.
I can only assume you want to build up your site a bit modular. (I.e. re-use the output of one controller method in other controller methods.) There's some plugins / extensions for CI that help you build like that. However, the simplest way is to use a library to build up common "controls" (i.e. load the model, render the view into a string). Then you can return that string and pass it along to the other controller's view.
You can load into a string by adding true at the end of the view call:
$string_view = $this->load->view('someview', array('data'=>'stuff'), true);
test.php Controller File :
Class Test {
function demo() {
echo "Hello";
}
}
test1.php Controller File :
Class Test1 {
function demo2() {
require('test.php');
$test = new Test();
$test->demo();
}
}
Very simple way in codeigniter to call a method of one controller to other controller
1. Controller A
class A extends CI_Controller {
public function __construct()
{
parent::__construct();
}
function custom_a()
{
}
}
2. Controller B
class B extends CI_Controller {
public function __construct()
{
parent::__construct();
}
function custom_b()
{
require_once(APPPATH.'controllers/a.php'); //include controller
$aObj = new a(); //create object
$aObj->custom_a(); //call function
}
}
I agree that the way to do is to redirect to the new controller in usual cases.
I came across a use case where I needed to display the same page to 2 different kind of users (backend user previewing the page of a frontend user) so in my opinion what I needed was genuinely to call the frontend controller from the backend controller.
I solved the problem by making the frontend method static and wrapping it in another method.
Hope it helps!
//==========
// Frontend
//==========
function profile()
{
//Access check
//Get profile id
$id = get_user_id();
return self::_profile($id);
}
static function _profile($id)
{
$CI = &get_instance();
//Prepare page
//Load view
}
//==========
// Backend
//==========
function preview_profile($id)
{
$this->load->file('controllers/frontend.php', false);
Frontend::_profile($id);
}
I posted a somewhat similar question a while back, but regarding a model on CI.
Returning two separate query results within a model function
Although your question is not exactly the same, I believe the solution follows the same principle: if you're proposing to do what you mention in your question, there may be something wrong in the way you're coding and some refactoring could be in order.
The take home message is that what you're asking is not the way to go when working with MVC.
The best practice is to either use a Model to place reusable functions and call them in a controller that outputs the data through a view -- or even better use helpers or libraries (for functions that may be needed repeatedly).
You can do like
$result= file_get_contents(site_url('[ADDRESS TO CONTROLLER FUNCTION]'));
Replace [ADDRESS TO CONTROLLER FUNCTION] by the way we use in site_url();
You need to echo output in controller function instead of return.
You can use the redirect() function.
Like this
class ControllerA extends CI_Controller{
public function MethodA(){
redirect("ControllerB/MethodB");
}
}
Controller to be extended
require_once(PHYSICAL_BASE_URL . 'system/application/controllers/abc.php');
$report= new onlineAssessmentReport();
echo ($report->detailView());
You can use the redirect URL to controller:
Class Ctrlr1 extends CI_Controller{
public void my_fct1(){
redirect('Ctrlr2 /my_fct2', 'refresh');
}
}
Class Ctrlr2 extends CI_Controller{
public void my_fct2(){
$this->load->view('view1');
}
}
very simple
in first controllr call
$this->load->model('MyController');
$this->MyController->test();
place file MyController.php to /model patch
MyController.php should be contain
class MyController extends CI_Model {
function __construct() {
parent::__construct();
}
function test()
{
echo 'OK';
}
}
