I am trying to create library that will write "error" messages in database, I do not think that I will be able to write PHPs errors nor CodeIgniters, but I can write my own "errors" something like
$this->error->write("User is not allowed to go in here");
I know there is a error handling already built in CodeIgniter on top of all it only supports writing errors/infos/debugs in file not database.
The real question is: how to get controller that called function.
Lets say I am in controller -> ./admin/settings.php and error ocures, code will call my library and I want it to store controller that called it. (I may be forced to send it as parameter but I don't want to write manually that it was fcn("error text", "/settings.php");
Assumed output: /controllers/admin/settings.php somewhere inside class that is called by controller.
You can use the router class to get this info
Also works with Codeigniter v3.0.x
To get the controller(class)
$this->router->class
To get the method(function)
$this->router->method

I want for a certain Laravel Job class to change the behaviour of the logging system. This is how my logs look right now:
[2018-08-22 08:31:24] production.INFO: [do-harvester-job]
[template: 598 - theme: 2592]Doing tasks
This is achieved by the following code:
\Log::info("{$this->harvester_job->log_prefix()}Doing tasks");
The problem is that I have a lot of log calls like this one and it gets cumbersome to always add the call to the log_prefix method.
Is there any way of prepending that info to the log without having to concatenate it inside the log call?
If you are facing problems in displaying the class data inside log file then you can use json_encode($className->fetchAllData()).
Hi I am facing some problems in writing a cron job using CI CLI way. My application has a controller name called manager.php in that there is method called check_status where I am gonna get all the order_ids using one model function. Ever order_id row had a status filed in database which either success or failure.
I have an api if i pass order_id to that it will tell whether order is successfully delivered or not. But here comes the problem I have below line in controller in the top.
<?php if(! defined('BASEPATH') ) exit("NO Direct Script Access Allowed"); ?>
So when i try to run method check_status from CLI in CI it gives me an error stating NO Direct Script Access Allowed.
This is the way i called above method php application/controllers/manager.php check_status
So i decided like this i created an another class file called cron_job.php in that i didn't keep the above error line "No Direct Script Access Allowed". I thought it will give access now when i try to run but it doesn't give an error and even output also.
This is the class which i created and method in that.
<?php
class Cron_job extends CI_Controller {
public function message($to = 'World')
{
echo "Hello {$to}!".PHP_EOL;
}
}
?>
I run this controller form CLI like this php application/controller/cron_job.php message
Note: I am in ROOT directory.
No Output at all. So i tried in another way like this php index.php application/controller/cron_job.php message
Now it gives me error stating that Error 404 page not found.
What i tried in another way now i created a file in views folder and in that i am calling old controller/method url like below.
$result = file_get_contents("http://application_path/controller/method");
echo $result;
Now i am getting output which i defined in the method check_status in manager.php controller.
But here comes another problem now after the above line i will get an array output which had all the order_ids.
I am gonna send this each id to a api to check status. If it is failure it will check whether it is delivered or not. If it's done i need to update that status in the database against that order_id. But now i am in view file, is it possible to call a model file from the view file or is there any way to do this.
Any help?
Note: There is no syntax errors in any controller or any method , which are fully verified and working normally when i am accessing using urls.
You need to read the CodeIgniter help section on Running via the Command Line. It's very easy. Your original approach was correct. But you do not call your controller method directly by its path, instead CD to your project root and then the call the index.php file with the controller and method as parameters.
// This is how you call CI via the command line.
// Use spaces between index.php and your arguments.
$ php index.php <controller> <method> [params]
// And in your instance
$ php index.php manager check_status [param1 param2 param3]
Depending on your host you may need to call the PHP version compiled for CLI.
the ci helper will help you in this.
1 ) Create a helper & create a function in it, that calls your model function
function getUserDetails($userId = '') {
$CI = & get_instance();
$getUserDetailsByUserId = $CI->user_model->getUserDetailsByUserId($userId);
return $getUserDetailsByUserId;
}
2) Now you can call getUserDetails($userId); in your view.
In my codeigniter i created a library in library folder.I want to load view pages in that library.How can i do this?
This is my code:
$this->load->view('view_page');
But when iam using this code i get an error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: CI_theme_lib::$load
Filename: libraries/theme_lib.php
Line Number: 9
What is the problem in mycode?
In Line number 9 in library the code is :
$this->load->view('view_page');
To do what you're trying to do you need to get an instance of CI, and use that.
e.g.
$CI =& get_instance();
Within your library functions you could then use this variable to load the view:
$CI->load->view('view_page');
I would question though why you want to call a view, in the form that you have done, within a library. I suspect that you would be better to get the view call to return data (setting the 3rd parameter 'true') and then have your library return the display data to the controller.... Your approach seems messy, but then I have no idea what your library is trying to do.....
I have came across your question for different reason, I seem to have problem passing variables to views instead. Let me explain before I tell you answer to your problem.
Imagine you have an Emailer library to send emails rather than sorting that out in controller.
Emailer than within itself builds email string using views. My problem is that when I make my call from controller something like Emailer::send_mail($data,$template) it passes the variables correctly but when I do it from another library the view fails to register the variables. LOL
So yes Stéphane Bourzeix you do sometimes want to use output from view in a different way than just returning to client browser.
The solution is here.
https://www.codeigniter.com/userguide2/general/views.html
the last section of that page has something like
$string = $this->load->view('myfile', '', true);
but something like
$string = $this->load->view('myfile', $view_data, true);
should work too
in case of doing this from other places than controllers you will need to:
$this->ci = & get_instance();
$string = $this->ci->load->view("myfile",$view_data,true);
it seems like the last argument in the list (true) is the one that tells it not to render to browser but instead just create string with template content
I know it's a bit too late but hope it still helps to some. Good luck with your code.

You simply DON'T load pages (aka Views) in a Library.
I don't see any need for doing this.
I am learning how to use codeIgniter as my php framework. I am reading through the documentation and watching the intro video and just generally following along with the first tutorial, but it's not working for me.
I have created a controller called "test.php" and a view called "test_view". The controller for this class is exactly like "welcome.php" and the view file just has some static html. However, when I go to index.php/test I get a 404 error.
I have also tried manipulating the original welcome files so that instead of calling a view it just echos "testing", yet I still see the original welcome message! I've tried clearing my browsing cash and refreshing, but to no avail.
Any suggestions? Thanks.
Edit: Here's the code for controllers/test.php
<?php
class Test extends Controller {
//Just trying to get it to echo test
public function index()
{
echo "test";
//$this->load->view('test_view');
}
}
?>
Try looking at this page in the documentation - this might solve your problem.
This basically means you should try typing index.php?/test/ instead (notice the question-mark).
First of all, check the above link. Might be useful.
If not, then...
Try changing the default controller in the config file ('routes.php') to something else (probably, to 'test'), then try loading index.php. Just to test whether the whole system works (or not).
Check whether mod_rewrite is loaded (in your server .conf-file, if you're using Apache).
Try using the latest build of the framework. AFAIK, the name of the controller class for now is "CI_Controller".
Finally, try removing the word 'public' before the declaration of the function. AFAIR, CI enable you to make private functions in controllers just by using prefix (which is set in the config file) at the beginning of the name of the function (thus making all the other functions public).
But most certainly the problem is with the mod_rewrite. If not, try debugging with die('Page found'); instead of echo - this will allow you to track possible redirects on the page.
I have a project based on codeigniter. And I should use one class that extended from a codeigniter controller in another php file. But I didn't find the solution about how to teach another php file to see whole CI-project. Beyond that needed class can not inherit when i call it from other place.
I'm not 100% sure if this helps get you in the right direction, but kudos if it does!
Codeigniter routes the application depending on the environment state of the URI. What you need to do is set the environment and include the index view file like so:
$_SERVER["REQUEST_URI"] = "cms/2";
//Set GET action,method params etc
require_once "path/to/index.php";
When you load CI Index file it reads the SERVER Variable and others which you may have to find and execute the controller and method, I would also advise that you modify the library/view file as it may exit upon output causing your script to exit.
Also you may wis hto look into ob_start() to catch the buffer.
