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.

I have a PHP daemon script running on the command line that can be connected to via telnet etc and be fed commands.
What it does with the command is based on what modules are loaded, which is currently done at the start. (psuedocode below for brevity)
$modules = LoadModules();
StartConnection();
while(true){
ListenForCommands();
}
function LoadModules(){
$modules = Array();
$dir = scandir("modules");
foreach($dir as $folder){
include("modules/".$folder."/".$folder.".php");
$modules[$folder] = new $folder;
}
}
function ListenForCommands(){
if(($command = GetData())!==false){
if(isset($modules[$command])){
$modules[$command]->run();
}
}
}
So, an example module called "bustimes" would be a class called bustimes, living in /modules/bustimes/bustimes.php
This works fine. However, I'd like to make it so modules can be updated on the fly, so as part of ListenForCommands it looks at the filemtime of the module, works out if it's changed, and if so, effectively reloads the class.
This is where the problem comes in, obviously if I include the class file again, it'll error as the class already exists.
All of the ideas I have of how to get around this problem so far are pretty sick and I'd like to avoid doing.
I have a few potential solutions so far, but I'm happy with none of them.
when a module updates, make it in a new namespace and point the reference there
I don't like this option, nor am I sure it can be done (as if I'm right, namespaces have to be defined at the top of the file? That's definitely workaroundable with a file_get_contents(), but I'd prefer to avoid it)
Parsing the PHP file then using runkit-method-redefine to redefine all of the methods.
Anything that involves that kind of parsing is a bad plan.
Instead of including the file, make a copy of the file with everything the same but str_replacing the class name to something with a rand() on the end or similar to make it unique.
Does anyone have any better ideas about how to either a) get around this problem or b) restructure the module system so this problem doesn't occur?
Any advice/ideas/constructive criticism would be extremely welcome!
You should probably load the files on demand in a forked process.
You receive a request
=> fork the main process, include the module and run it.
This will also allow you to run several commands at once, instead of having to wait for each one to run before launching the next.
Fork in php :
http://php.net/manual/en/function.pcntl-fork.php
Tricks with namespaces will fail if module uses external classes (with relative paths in namespace).
Trick with parsing is very dangerous - what if module should keep state? What if not only methods changed, but, for example, name of implemented interface? How it will affect other objects if they have link to instance of reloaded class?
I think #Kethryweryn is something you can try.
I am struggling to understand scope and what's preventing my new code from working (assuming it is a scope issue).
The following function is in a file PATH.'/includes/custom-functions.php' that references a class:
function infusion() {
require_once(PATH.'/classes/infusion.php'); //PATH is defined in WordPress from ~/wp-content/themes/theme/
return new infusion();
}
The class is reliant on PATH.'/api/isdk.php' and connection credentials from another file within /api/ directory. From within PATH .'/includes/custom-functions.php', I have many other functions that call $infusion = infusion(); and work perfectly.
PROBLEM
I have created a new file: PATH.'/includes/report.php' which I need to access $infusion = infusion();but can't get to work by either repeating the function infusion() definition from above; using require_once();; or using include();. All 3 of those options simply kill the rest of the code and I can only come to the conclusion - well, I have no conclusion.
Any help would be greatly appreciated.
I'm assuming the code isn't using namespaces, therefore you aren't permitted to redeclare the infusion function (either by redefining the function, or re-including the class).
Your includes/report.php file should simply have:
require_once PATH.'/includes/custom-functions.php';
// your other code here ...
$infusion = infusion();
It may be the case that other files / classes that you're including in your file are already requiring custom-functions.php along the line, so you may be able to skip that entirely. Also note that the PATH constant should have already been defined somewhere (either directly or via an included file) before you attempt to use it. If you set your error_reporting to include E_ALL, you'll get a notification in your error log if that constant doesn't exist.
If that fails, your error log(s) may provide some additional background on what your issue is.
Here's the situation:
I have a catch-all on my domain email (so *#domain.com) redirecting to a piping script located at /home/domain/scripts/piper.php. This piper script is not within the Kohana ORM, but all of my other files are. I want to try to use Kohana inside this piper.php file.
I have tried (unsuccessfully) all of the following:
Including Kohana
I couldn't figure out what needed to be included, and more importantly how to override the url variable that Kohana uses to determine the right controller. Also, this is a catch-all piper, so it isn't using HTTP (to my knowledge), so much as executing a command.
Piping
I tried piping to the following:
/home/domain/public_html/index.php --uri="piper"
But cPanel makes this impossible, as you can only specify the destination script, and not the proper flags and such (unless I am missing something).
PHP exec()
I tried using the following line:
exec("php /home/domain/public_html/index.php --uri=\"/piper\"")
I was hoping that the stdin data would be maintained across the exec() command, but I could never get it to recognize the uri command, though I can run this on my localhost and it works just fine.
I was using http://www.coderelic.com/2011/10/creating-cron-jobs-in-kohana-3-x-is-a-piece-of-cake/ as a reference, but can't get anything to work.
I'm happy with either one of these solutions such that I can see an incoming email, parse it, then send emails based on the parameters.
Let me know if you need more information! I'm le stumped.
/home/domain/public_html/index.php --uri="piper" would be a valid way to do it. If your host sucks and doesn't let you specify that, put it into a bash script instead and reference that.
If you are on any recent version of kohana (3.2 or 3.3), a better way to do this would be to use Minion to run the command line task. This is what Minion was designed for.
All you need to do is to:
modify your piper.php script to be a valid PHP class;
place it in /application/classes/ folder;
Kohana will automatically load your class file (like include) during initialization.
Then you can use your piper class as usual class by $piper = new Piper; ....
UPD
You have to serve your emails trough Kohana.
Create controller, for example pipe (route it with /pipe URL):
public function action_pipe() {
$pipe = new Pipe; // This creates new Pipe object (your emails serving class)
$pipe->serve(); // Sserve emails within `serve()` method of Pipe class
}
Although admittedly, I'm not sure if these other answers are correct because I can't figure out how to reproduce the results.
What ended up working for my situation was to create a Controller_Piper class that is called in the /home/domain/scripts/piper.php. What I did was to copy the code from /home/domain/public_html/index.php and changed the following:
echo Request::factory("/piper")
->execute()
->send_headers(TRUE)
->body();
This loads the piper controller and executes everything very nicely. Not sure if it's the cleanest, but it does work.
Let's say I'm writing a global logData method that wants to write to a log file that has the same name as the php that's running it, but with a .log extension.
I'm including this logging in a parent php with the intention of having it always write to log files that are whatever the *parent file name is (not the tools.php lib in which it's sitting).
So, I have
/some/arbitrary/directory/parent.php
which calls
include ("/path/to/my/php/libs/tools.php");
but when I run my logging method that's in tools.php it logs to a file called
/path/to/my/php/libs/tools.php.log
rather than
/some/arbitrary/directory/parent.php.log (which is what I'd like).
I'm using __FILE__ which is behaving this way (probably as its intended to). Is there a command for getting the parent's file name so that I can get this to work as I intend? Or will I have to pass FILE as a param into my method from the parent php to get it to write to the correct output file?
TIA
You could probably use $_SERVER["SCRIPT_FILENAME"]
debug_backtrace() will give you what you need.
http://php.net/manual/en/function.debug-backtrace.php
You need to pass __FILE__ to the log class.
Something like:
// file:/some/arbitrary/directory/parent.php
$logger = new Logger(__FILE__);
// file:/path/to/my/php/libs/tools.ph
public function __construct($file) {
// But it is not good idea to save log file same with php files.
$this->log_path = $file.'.log';
}
I am learning how to use codeIgniter as my php framework. I am reading through the documentation and watching the intro video and just generally following along with the first tutorial, but it's not working for me.
I have created a controller called "test.php" and a view called "test_view". The controller for this class is exactly like "welcome.php" and the view file just has some static html. However, when I go to index.php/test I get a 404 error.
I have also tried manipulating the original welcome files so that instead of calling a view it just echos "testing", yet I still see the original welcome message! I've tried clearing my browsing cash and refreshing, but to no avail.
Any suggestions? Thanks.
Edit: Here's the code for controllers/test.php
<?php
class Test extends Controller {
//Just trying to get it to echo test
public function index()
{
echo "test";
//$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.
