how can I display errors in codeigniter? - codeigniter

i don't seem to be able to show errors in codeigniter.
I've changed the Index.php file to development and also added error reporting and display errors like this
define('ENVIRONMENT', 'development');
switch (ENVIRONMENT)
{
case 'development':
error_reporting(E_ALL);
ini_set(‘display_errors’,1);
break;
//....
with this setup I would expect to get errors when, for example, i try to load a model which doesn't exist, or there is a typo in my code or any other error. but all i get is a blank page...

Can't you enable error reporting in php.ini?

Laravel Exceptions handling when debug=false

I use the default Laravel Exception handler, but I have a question regarding good practices.
When I have a condition in which the controller must throw an exception, I do the following:
if($blah) {
abort(500, "The user should not be here");
}
and then on the frontend, I have a view that handles the error as this:
#section('message', __($exception->getMessage() ?: 'Whoops, something went wrong on our servers.'))
So that works great as long as I have the following on the .env file:
APP_DEBUG=true
Whenever I change this value to false, (as it should in production), all I get on the error page is: Server Error instead of my custom message.
How can I keep my custom error message, and have APP_DEBUG=false in production?
If you want to customize you HTTP errors for specific views or conditions, then you will have to look into Rendering exceptions section that will show you how to show a custom view for a specific exception. With this you can throw an exception like
throw new UserNotFoundException();
and listen to that exception and render a specific view as required.

How to make debug page in laravel?

I have set mode in .env file as: APP_DEBUG = false;
Now when error is happen it shows empty page with header: "Error".
How to make separated page for that?
You create a template in the views/error folder with name after the error code you want it to handle see https://laravel.com/docs/5.4/errors#custom-http-error-pages
You can create Blade templates for specific HTTP error codes in resources/views/errors/xxx.blade.php. For instance you can make resources/views/errors/500.blade.php for Internal Server Errors or resources/views/errors/404.blade.php for instances where a page can not be found. More here: https://laravel.com/docs/5.4/errors#custom-http-error-pages

Laravel 4: Redirecting when invalid route

I am trying to treat the invalid requests on my Laravel app, something like redirecting to the root will work just fine, but I can't manage to do it.
In the documentation and around stackoverflow I saw this is always the solution:
App::missing(function() {
# handle the error
});
I thought that would just go to the routes file but no. Then I saw in some post it should be in the app/start/global.php file but it still didn't work.
In the docs it says I can "register an error handle". Is that what I should do? What does this mean? What should I do?
Ultimately this can be put anywhere, but app/start/global.php is probably the best place for it.
App::missing(function($exception)
{
return Response::view('errors.missing', array(), 404);
});
Try putting this in there. In fact, if you've just setup a fresh installation, you should already have one there.
Here is how you can register an error handler, like so;
App::error(function(Exception $exception, $code)
{
//Now you can check for different exceptions and handle each on their own way.
}
This will be for PHP general Exception class which will make all exceptions go here, but you can change Exception to the specific Exception class of you own and handle it accordingly.
App::missing will generally be called when a page within your site has not been found, allowing you to show a default page for when users have found a non existing page. So if you are wanting to handle missing pages, use App::missing else use App::error.

CodeIgniter redirect not working on a real Server

I'm having a problem with CI 2.1.3 redirect function.
Everytime I call redirect, it shows a white-blank page. In fact, it works well on my localhost, the problem just occurs on my real server (with CentOS 5 installed).
This is how I call the redirects :
redirect('frontend/article/index');
or
redirect(base_url('articles.html'));
I did add a route in config/routes.php
$route['articles.html'] = 'frontend/article/index';
with : frontend is module, article is controller, and index is action (I'm using wiredesignz's HMVC module extension)
How could I fix it? And what is the problem here?
Thanks in advance!
UPDATE
I replaced CI redirect function by calling :
header("Location: http://example.com");
but it didn't work too.
So I created a file named info.php and uploaded it to my server. Here's the content:
<?php
phpinfo();
?>
When I type in the address bar : http://example.com/info.php, it shows like in the image.
Why was there a ">" character? Was it the problem causing redirect not working?
Firstly, make sure error reporting is enabled, or try placing the following at the top of your index.php.
error_reporting(E_ALL | E_WARNING | E_NOTICE);
ini_set('display_errors', TRUE);
If this doesn't point you in the right direction make sure you don't have any output echo, print_r, print, dump, etc before your call to redirect() method.
Another common cause or problems when moving to a new environment is white space. Check that your files don't have any whitespace at the bottom of them.
if you are defining .html in the config.php as the file ext. you do not need to postfix the route with it.
$route['articles'] //instead of $route['articles.html']
Also you need to remove the base_url() from the redirect cos that is not needed.
redirect('articles'); //should sort it
Hope this sorts ur problems.
EDIT
If this is still not working after attempting these changes, it will most likely be a problem in the controllers. If this is the case you may need to turn on error reporting in your index.php file to find out exactly where the problem is occurring.

Routing issue with 404_override

I'm having an issue with 404_override in CI 2.02. Here is my default controller and override:
$route['default_controller'] = "home/index_controller";
$route['404_override'] = "misc/site_map";
This line uncommented gives me this error:
Unable to load your default controller. Please make sure the
controller specified in your Routes.php file is valid.
But commented, I get a 404 error. So something in the override is causing the problem. I just don't know what. I've tried various MY_Router files and they don't help. Anyone have any suggestions about how I can fix this?
I've eliminated my .htaccess file as the problem by deleting it from the server and then trying to access a controller that doesn't exist like this: http://domain.com/index.php/doesnotexist. I still get the error.
For anyone else coming here with this issue, this is/was a bug in CodeIgniter itself to do with 404 pages not being able to be included in subfolders.
Bug Discussion Including Fix on GitHub
You have forgotten to add the default controller that will be used when you first load your website, in your routes.php you need to add this, it is required which is why you're seeing the errors being thrown.
$route['default_controller'] = 'index'; // this will need to be changed to your default controller
$route['404_override'] = 'misc/site_map';
EDIT:
Okay, you must make sure you enter the correct controller name you wish to load as the default, for example you have home.php in your controllers folder, you must enter home as the default. Optionally, you can define segments that are functions in your home.php class file, e.g. home/function_name.
