This is my first CI project so forgive me.
I simply can't hit a method with an AJAX call. It keeps coming up as a 404 in Web Inspector.
I have a controller called "home.php". It's working. I can land on my home page.
Then I have this AJAX call firing on a hover event
function showDataWindow(){
// i might switch this to data attr, but for now item IDs are contained in class
var thisClass = $(this).attr('class');
var thisIDpos = thisClass.indexOf("id-")+3;
var thisID = thisClass.substr(thisIDpos, 3);
alert(thisID); // alerting correctly
$.post('getMoreInfo', { ID: thisID},
function(data) {
.. act on data
I simply can find the method I am calling - getMoreInfo. Always 404.
I have a home.php class in my controllers and its set as my default, and it works because I am landing on my home page and getting the index. But in that home controller is also my getMoreInfo function...
public function getMoreInfo()
{
$ID = $_POST['ID'];
$this->load->model('Artist_model');
$assocReturned = $this->Artist_model->get_more_info($ID);
echo json_encode($assocReturned);
}
And I feel like there is a tiny MC Hammer guarding that function. "You can't touch this". He mocks me in his little parachute pants and minuscule fade.
I think it must be how I am doing my URI in the Jquery AJAX post? I have index re-writing in my htaccess (which I am kind of foggy on exactly)
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?$1 [L]
But I have tried just about every URI permutation in that AJAX call
www.mySite.com/index.php/home/getMoreInfo
index.php/home/getMoreInfo
index.php/getMoreInfo
/home/getMoreInfo
home/getMoreInfo
/getMoreInfo
getMoreInfo
!
And none have worked.
What you have to call depends on how your router is configured.
Default call would be /home/getMoreInfo, but could be changed if you have reconfigured your router. Reference: http://codeigniter.com/user_guide/general/routing.html

I am creating a web application in Codeignitor using Laragon as my local server. When I try to "redirect" to a Controller - I get "404 Page Not Found". If I redirect to View - it works. I can access Controllers with other methods such as "Form Open".
Here is my .htaccess file:
RewriteEngine on
RewriteCond $1 !^(index\.php|assets|images|js|css|uploads|favicon.png)
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
RewriteRule ^(.*)$ index.php/$1 [L]
This is my Controller - for a test I used Redirect to a View "page-login" and a Controller "Private-area". I can access the View, but the Controller sends to 404 Page Not Found.
if($this->form_validation->run()){
$result = $this->login_model->can_login($this->input->post('user_email'), $this->input->post('user_password'));
if($result == ''){
redirect('private_area');
}
else {
$this->session->set_flashdata('message', $result);
redirect('page-login');
FYI I can access Controllers (in this example "Register") using other methods such as Form Open like this:
<?php echo form_open('register/validation'); ?>
Why do I get the 404 error?
Your redirect syntax is incorrect:
the CI function redirect() is structured like this:
redirect($uri = '', $method = 'auto', $code = NULL)
keep in mind to use a relative path like '/my_controller/my_function'
as in this example:
redirect('/login/form/');
you need to autoload/load the URL helper with: $this->load->helper('url');
the form_open() syntax is correct, you need to autoload/load the Form Helper with: $this->load->helper('form');
redirect() function
Does a “header redirect” to the URI specified. If you specify the full site URL that link will be built, but for local links simply providing the URI segments to the controller you want to direct to will create the link. The function will build the URL based on your config file values. (- source)
So, the url must be
redirect("/controller/method/parameters");
Or full url
In your code, Codeigniter will look for the index() method of private_area controller.
Thanks All!
So I think #Don'tPanic nailed it. I thought "Redirect" would point to a Controller - but it points to a Route. So I created a Route in my Routes.php file where
$route['private_area'] = 'private_area';
And everything works. Is this the correct way to do this?
Ie to define Routes in the Routes.php file...then call upon them as required using "Redirect"?
I have bad english, but i hope I can explain you my situation.
I have payment controller and two methods.
class payment extends MX_Controller{
public function __construct(){
parent::__construct();
$this->load->model(get_class($this) . "_model", "model");
}
public function pay(){
//Gets form data and sends to payment service
}
public function check(){
//Gets response from payment service and acts according payment
//status
}
}
First sends data to payment service and second have to do something according payment response scenario.
So in my payment cpanel I wrote this url "htts://my-domain.do/payment/check" for response.
The first method works successfully, it sends all needed data, but my second "check()" method does not called.
When I simply write https://my-domain/payment/check it still not working, but when I call like this https://my-domain/index.php/payment/check it works.
My .htaccess also configured.
I use CI 3. Is there any one who had the problem like this.
My .htaccess file look like
RewriteEngine On
Options +FollowSymLinks
Options -Indexes
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule . index.php [L,QSA]
And in app/config/config.php
$config['index_page'] = '';
I am trying to figure out the best approach when linking to static pages using a loosely followed MVC design pattern.
I begin by rewriting all requests to the index.php which handles all request and break them down the url into the controller, action and parameters. However if i don't want to follow this url structure and just want to visit a static page such as 'http://example.com/home/' without having to call some action how would i achieve this without getting a php error caused by my router/dispatcher trying to request a file that does not exist?
I thought about setting up some switch statement or a if statement as shown below that checks if the url is set to something then uses a custom defined controller and action, or i wasn't sure whether to take the static resources out of the MVC directory and have it seperate and link to it that way?
<?php
class Router
{
static public function parse($url, $request)
{
$url = trim($url);
if ($url == "/")
{
$request->controller = "tasks";
$request->action = "index";
$request->params = [];
}
else
{
$explode_url = explode('/', $url);
$explode_url = array_slice($explode_url, 2);
$request->controller = $explode_url[0];
$request->action = $explode_url[1];
$request->params = array_slice($explode_url, 2);
}
}
}
?>
This works, but i'd rather not have a huge router setup for many different static resources as it feels tacky and that i am just patching together code. Would putting static pages in its own directory outside of MVC and linking to them in the views be a valid option? i'm relatively new to MVC so any guidance would be great.
Your application shouldn't receive request it is not supposed to handle, you can solve this on a webserver level:
if you are using apache for example, you can setup in the .htaccess file that the request should be directed to your front controller (ex: index.php) only if the requested resource does not exist
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /index.php [L]
I'm trying to setup a blog script on a website running on the CodeIgniter framework. I want do this without making any major code changes to my existing website's code. I figured that creating a sub domain pointing to another Controller would be the cleanest method of doing this.
The steps that I took to setup my new Blog controller involved:
Creating an A record pointing to my server's ip address.
Adding new rules to CodeIgniter's routes.php file.
Here is what I came up with:
switch ($_SERVER['HTTP_HOST']) {
case 'blog.notedu.mp':
$route['default_controller'] = "blog";
$route['latest'] = "blog/latest";
break;
default:
$route['default_controller'] = "main";
break;
}
This should point blog.notedu.mp and blog.notedu.mp/latest to my blog controller.
Now here is the problem...
Accessing blog.notedu.mp or blog.notedu.mp/index.php/blog/latest works fine, however accessing blog.notedu.mp/latest takes me to a 404 page for some reason...
My .htaccess file looks like this (the default for removing index.php from the url):
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
And my Blog controller contains the following code:
class Blog extends CI_Controller {
public function _remap($method){
echo "_remap function called.\n";
echo "The method called was: ".$method;
}
public function index()
{
$this->load->helper('url');
$this->load->helper('../../global/helpers/base');
$this->load->view('blog');
}
public function latest(){
echo "latest working";
}
}
What am I missing out on or doing wrong here? I've been searching for a solution to this problem for days :(
After 4 days of trial and error, I've finally fixed this issue!
Turns out it was a .htaccess problem and the following rules fixed it:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
Thanks to everyone that read or answered this question.
Does blog.domain.co/blog/latest also show a 404?
maybe you could also take a look at the _remap() function for your default controller.
http://ellislab.com/codeigniter/user-guide/general/controllers.html#default
Basically, CodeIgniter uses the second segment of the URI to determine which function in the controller gets called. You to override this behavior through the use of the _remap() function.
Straight from the user guide,
If your controller contains a function named _remap(), it will always
get called regardless of what your URI contains. It overrides the
normal behavior in which the URI determines which function is called,
allowing you to define your own function routing rules.
public function _remap($method)
{
if ($method == 'some_method')
{
$this->$method();
}
else
{
$this->default_method();
}
}
Hope this helps.
have a "AllowOverride All" in the configuration file of the subdomain in apache?
without it "blog.notedu.mp/index.php/blog/latest" work perfectly, but "blog.notedu.mp/latest" no
$route['latest'] = "index";
means that the URL http://blog.example.com/latest will look for an index() method in an index controller.
You want
$route['latest'] = "blog/latest";
Codeigniter user guide has a clear explanation about routes here
I'm trying to learn MVC design pattern for web applications so I decided to write my own PHP MVC framework. Before writing this post I read a lot of tutorials and forums about MVC. Now I pretty well understanding the MVC idea, and how communicate controller-model-view. I have write router and few modules (login, categories, ...) - seems it's working.
Now I'm confused a bit:
If I call localhost/LogIn I get only login form, if I call localhost/categories I get category list. Everything OK, but I want to create index controller and when calling localhost/index I want see login form, categories and a lot more modules.
Should I call controllers (login, categories) from indexController.php?
I need advice how to concatenate needed modules in one page.
No, controllers shouldn't be calling each other's functions. Some frameworks introduce "helpers" to implement what you need.
Controllers can use the same models, and views anyway are going to be different, so you can use your Categories model to provide you categories to display (e.g. $categories->getCategoriesList()) and then using it in category controller view and also in index controller view.
A legitimate method of calling one controller from another is by forming an HTTP request - e.g. receiving an HTML snippet (another controller rendered view) to display in your view via AJAX or using an iframe with a source pointing to your another controller (which is a clumsy solution, mostly for idea illustration).
You need several things:
You need a .htaccess file that will cause all requests to go through your index file, here is a simple one:
RewriteEngine On
RewriteBase /demo
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]
In the index.php file you need to set the include path, so you won't have to explicitly include the modules/controllers/views or any other class you choose:
define("APPLICATION_PATH", realpath('.'));
$paths = array(
APPLICATION_PATH.'/controllers',
APPLICATION_PATH.'/models',
APPLICATION_PATH.'/views',
APPLICATION_PATH.'/libs',
APPLICATION_PATH.'/includes',
get_include_path()
);
set_include_path(implode(PATH_SEPARATOR, $paths));
now add the 'magic method' for autoloading classes (called automatically) and initialize your Bootsrap class:
function __autoload($className){
$fileName = str_replace('\\','/', $className);
require_once "$fileName.php";
}
new Bootstrap();
Bootstrap.php:
<?php
class Bootstrap {
public function __construct() {
$url = $_GET['url'];
$params = explode('/', $url);
//if controller exist - call it, else call login controller
if (isset($params[0]) && $params[0]){
$controller = new $params[0]();
}
else{
$controller = new login();
}
//if method exist - call it, else call index method
if (isset($params[1]) && $params[1]){
//if parameter exit - call method with param, else call witout param
if (isset($params[2]) && $params[2]){
$controller->$params[1]($params[2]);
}
else{
$controller->$params[1]();
}
}
else{
$controller->index();
}
}
}
That should give you a basic MVC Framework.
Use your controller (index.php) to centralized code that would be used on every page (request validators, error handles, exception handlers, session stuff).
Create a Router class to get the correct models. Allow the models to get the correct views. I have included some UML diagrams from my other answer (https://stackoverflow.com/questions/42172228/is-this-how-an-mvc-router-class-typically-works) to help out. Remember, try to program to an abstract interface, not to a concrete implementation.
