I have a controller base class that extends CI_Controller and then some other classes that extends my controller base class.
I would like to add some new features in the lowest hierarchy controller in the http post method case but when i submit the form the execution doesn't go through the child post method condition.
Is like the post method call will goes to previous controller class and not pass through the child function.
I have tried a function with only http get case and works.
UPDATED: sorry my error.
I found the problem, I have a redirect in parent post method, this is the reason why the execution does not go through child post method condition, ¿ are there any way dynamically to redirect in the child if exist a function that overrides the parent function or redirect in the parent if the method does not be overridden by any subclass ?
class MY_Controller extends CI_Controller {
public function __construct() {
parent::__construct();
}
public function create() {
if ($this->input->server('REQUEST_METHOD') == 'POST') {
//do things...
redirect();
}
else
{
//do other things...
}
}
class One_Controller extends MY_Controller {
public function __construct() {
parent::__construct();
}
public function create() {
parent::create();
if ($this->input->server('REQUEST_METHOD') == 'POST') {
var_dump('POST');
//do more things...
redirect(); // here and not in the parent
}
else {
var_dump('GET');
}
}
}
Anybody could help or guide me to the solution ?
Thank you so much.

This is something strange.
The controller function called product just doesn't work, but any other name works. See the following code:
namespace App\Controllers;
class Shop extends BaseController {
public function index() {
return view('shop');
}
public function asdf(){
return view('product');
}
public function product(){
return view('product');
}
}
Calling the function asdf (or whatever name it is), works. But I get a 404 if I call the /shop/product.
How to explain (and hopefully solve) it?
I have a CustomController. For not to repeat myself, I defined getVars function in BaseController. I want to call getVars function from some functions in CustomController.
However, Laravel returns 404 error without any exception. What is wrong?
class BaseController extends Controller {
public function getVars($var1, $var2, $var3=Null, $var4=Null) {
return [];
}
}
class CustomController extends BaseController {
public function doBla1($var1, $var2) {
$vars = $this->getVars();
}
public function doBla2() {
$vars = $this->getVars();
}
public function doBla3() {
$vars = $this->getVars();
}
}
Sorry :( I found the reason of error. The names of doBla1 and getVars functions are same. This results in a 404 error. Sorry :(
$this is useful when you have method/function defined in same controller.
For functions inside parent controller you can use
Parent::getVars($var1, $var2)
I have a controller in Laravel 4, with a custom variable declared within it.
class SampleController extends BaseController{
public $customVariable;
}
Two questions: Is there any way I can call within a route filter:
The controller object where the filter is running at.
The custom variable from that specific controller ($customVariable).
Thanks in advance!
as per this post:
http://forums.laravel.io/viewtopic.php?pid=47380#p47380
You can only pass parameters to filters as strings.
//routes.php
Route::get('/', ['before' => 'auth.level:1', function()
{
return View::make('hello');
}]);
and
//filters.php
Route::filter('auth.level', function($level)
{
//$level is 1
});
In controllers, it would look more like this
public function __construct(){
$this->filter('before', 'someFilter:param1,param2');
}
EDIT:
Should this not suffice to your needs, you can allways define the filter inside the controller's constructor. If you need access to the current controller ($this) and it's custom fields and you have many different classes you want to have that in, you can put the filter in BaseController's constructor and extend it in all classes you need.
class SomeFancyController extends BaseController {
protected $customVariable
/**
* Instantiate a new SomeFancyController instance.
*/
public function __construct()
{
$ctrl = $this;
$this->beforeFilter(function() use ($ctrl)
{
//
// do something with $ctrl
// do something with $ctrl->customVariable;
});
}
}
EDIT 2 :
As per your new question I realised the above example had a small error - as I forgot the closure has local scope. So it's correct now I guess.
If you declare it as static in your controller, you can call it statically from outside the controller
Controller:
class SampleController extends BaseController
{
public static $customVariable = 'test';
}
Outside your controller
echo SampleController::$customVariable
use:
public function __construct()
{
$this->beforeFilter('auth', ['controller' => $this]);
}
I recently started using Codeigniter after having a structural problem in one of my Ajax-heavy applications. (You can read up on it if you want in my previous question)
I have a fairly short question. Currently I am making a lot of Ajax requests to different controllers. I open the controllers like this:
public function __construct()
{
parent::__construct();
$this->output->set_content_type('application/json');
}
And at the end of every function I do the following:
$this->returnValue['result'] = "ReturnedInfo";
$this->returnValue = json_encode($this->returnValue);
$this->output->set_output($this->returnValue);
The code is pretty clear in itself, but I don't want to keep repeating myself. The codeigniter manual says to do the following:
$this->output
->set_content_type('application/json')
->set_output(json_encode(array('foo' => 'bar')));
But I would still be repeating myself. Also, I don't want to add a function to every controller that does this, even if it does decrease redundancy.
Since all of my controllers return JSON, is there a way to set this globally in a config file maybe, or in any other way?
TL;DR I have this same piece of code in every controller/function. Since the output type is always the same, just not the result, is there a way to automate this process across every controller/function?
Create an Ajax_Controller that extends MY_Controller that extends CI_Controller.
The Ajax Controller will then inherit from both Controllers.
class Ajax_Controller extends MY_Controller
{
public function __construct()
{
parent::__construct();
if(!$this->input->is_ajax_request()) return show_error('Invalid Request');
}
public function jsonOutput($json)
{
//some data checking here....
return $this->output
->set_content_type('application/json')
->set_header("HTTP/1.1 200 OK")
->set_output($json);
}
}
-
class User extends Ajax_Controller
{
public function __construct()
{
parent::__construct();
}
public function userMethod()
{
$json = json_encode(array(
'' => ''
));
$this->jsonOutput($json);
}
}
Extend your controllers from your own base class rather than CI_Controller and put your repeatedly-used function(s) and constructor code in there. Something like:
class BaseController extends CI_Controller {
protected function index() {
$this->returnValue['result'] = "ReturnedInfo";
$this->returnValue = json_encode($this->returnValue);
$this->output->set_output($this->returnValue);
}
}
class Specific extends BaseController {
public function index() {
//do controller-specific stuff
parent::index();
}
}
I abstract this further if I have groups of controllers with shared code; for example, if I had a bunch of controllers that require the user to be logged-in I create AuthenticatedController, which extends BaseController and add session checks etc.
i'm using codeigniter for my project and i have this class model which i call Genesis which looks like this:
class Genesis_model extends CI_Model {
function __construct() {
parent::__construct();
}
function get() {
return 'human soul';
}
}
and i have another model, stored in the same directory, which extends Genesis_model
class Human_model extends Genesis_model {
function __construct() {
parent::__construct();
}
function get_human() {
return $this->get();
}
}
Human_model is used by Human controller
class Human extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->model('human_model');
}
function get_human() {
$data['human'] = $this->human_model->get_human();
$this->load->view('human/human_interface', $data);
}
}
if i execute the code, it will produce an error which point to return $this->get(). it reads "Fatal error: Class 'Genesis_model' not found in ...\application\models\human_model.php on line 2".
i use this method because nearly all my models shared almost identical structure. I gather the similar functionality in Genesis while the other models serve only as data suppliers unique to the tables they represent. it works well in my asp.net (vb.net) but i don't how to do it in codeigniter.
is there a way for Human_model to inherit Genesis_model. i don't think i'm allowed to use include('genesis_model.php'). i don't know if it works either.
thanks in advance.
core/MY_Model is good if there's only 1 important superclass for your models.
If you want to inherit from more than model superclass, a better option is to change your autoload configuration.
In application/config/autoload.php, add this line:
$autoload['model'] = array('genesis_model');
Put the file genesis_model.php in the core directory
Change your Human_model to this:
include('genesis_model.php');
class Human_model extends Genesis_model {
function __construct() {
parent::__construct();
}
function get_human() {
return parent::get();
}
}
notice the get_human function and the include.
You have to include the Genesis_model on your Human_model.php like this:
include_once( APPPATH . 'folder/file' . EXT );
Or you can autoload it on your config/autoload.php file, what I think is stupid =)
other solution
<?php
$obj = &get_instance();
$obj->load->model('parentModel');
class childModel extends parentModel{
public function __construct(){
parent::__construct();
}
public function get(){
return 'child';
}
}
?>
