So I have the following action in the controller. When Im using xDebug with Symfony 3 then the variables $request and $imNotBeingShowin is not shown in xDebug variable list. While variable $imBeingShown works fine when assigned to the class.
public function saveAction(Request $request)
{
$imNotBeingShown = 'why not?';
$this->imBeingShown = 'wooot';
}
Any idea what is going on? I can't seem to find anything about this issue in Google.

Edit: added an extra image for proof
Edit: app_dev.php variables are shown in debugger
I have added an additional image, with code while debugging :).
This won't work. Once you've run your program it's loaded into memory. You can't change it on runtime.

Im trying to learn Laravel framework and having trouble with getURLList();
In the tutorial that im following it says.
class StudInsertController extends Controller
{
public function insert(){
$urlData = getURLList();
return view('stud_create');
}
But the getURLLIST(); comes back as
Call to undefined function App\Http\Controllers\getURLList()
And i dont find any information about that.
Is it because the tutorial is for older version of Laravel?
The link to the tutorial itself is here:
https://www.studentstutorial.com/laravel/insert-data-laravel
Can somebody point me in the right direction.
I would have written this as a comment, but I don't have enough reputation.
From what the tutorials says, there are just a few files that you need to touch which effectly means they are not adding a custom helper method.
After looking at the code, I don't see any use for the line of code getting the URLs. It would have been useful if you were to pass the data forward to your view.
So I would recommend you remove the line $urlData = getURLList();. It should work just fine. I don't know if the author left it there by error.
I am in the process of migrating a site from my personal dev server onto Windstream's business hosting server. I've already run into the issue of having developed using PHP 5.4 only to find out that my static functions won't work on WS's 5.1.4 installation. I've since fixed those issues and am not facing one that I can't seem to find any help for on the internet.
All of the static functions I was using have been rewritten as functions outside the class scope. Instead of having
class Product{
...
public static function myFunction(){}
...
}
I now have
function myFunction(){}
class Product{...}
in my included Product.php file.
However, when I try to call myFunction() from my code, nothing happens. I know the nothingness comes from WS's error handling, but the point is, the function isn't working. To verify this, I have taken the following steps:
Inserted the line echo "entered included"; immediately following the <?php in Product.php. This prints "entered included" on the index page, indicating that my include is working. I have done the same thing before the final ?> with the same results, so I don't think it's getting hung up inside the included file.
I have changed myFunction() in the included file to be simply
function myFunction(){echo "myFunction works";}
A call to myFunction() still makes nothing happen.
I have moved myFunction() to the including file (myFunction() now lives in index.php instead of Product.php; index includes Product.php). This time, myFunction() executes without issue.
To my 'hack it til it does what it should' sensibilities, this tells me that the server is having a problem with functions that are declared in files that are included; honestly, though, I have absolutely no clue what's going on, and any help would be appreciated. Their website is currently down, and they were expecting it to only be offline for a day, so I'll try pretty much anything short of sacrificing a fatted calf.
I know I should be posting more specific code, but since this is a customer's actual website, I'm trying to put as little of the actual code out here as is possible. I'm happy to append specific sections of code to this entry as they are requested for clarification.
Thanks in advance for your consideration.
#Rottingham: First, thanks for the 3v4l link. Second, my assumption about static methods in 5.4 vs 5.1.4 came from this line of php.net's page on static members and methods:
"As of PHP 5.3.0, it's possible to reference the class using a variable. The variable's value can not be a keyword (e.g. self, parent and static)."
src - http://www.php.net/manual/en/language.oop5.static.php
Since my version and the server version were on different sides of the 5.3 mark mentioned, I incorrectly assumed that this was my problem.
Third, when I get in from my day job, I'll update my code to show errors and update this post if a solution has not yet been found.
Ultimately, my problem isn't with using static methods (since I don't have them anymore) but with using any function that is declared in an included .php file.
I have installed Aptana Studio 3, set my workspace as C:\wamp\www and set project nature only to PHP - primary. Everything is working (for ex. autocomplete from extended class) but PHP documentation simply is not working. I added some function like
/**
* Test
*/
public function error($status_code, $message = null) {
....
}
but when I hover it (I saved the file) I get No available documentation? Where is the problem? :/
I'm on Windows 7 32-bit.
The hover will not work when you are on the error word at the function declaration (a bug).
It should work for you when you call the error function. You should see the documentation-hover when you code assist, and also see similar info when you hover the word.
I am learning how to use codeIgniter as my php framework. I am reading through the documentation and watching the intro video and just generally following along with the first tutorial, but it's not working for me.
I have created a controller called "test.php" and a view called "test_view". The controller for this class is exactly like "welcome.php" and the view file just has some static html. However, when I go to index.php/test I get a 404 error.
I have also tried manipulating the original welcome files so that instead of calling a view it just echos "testing", yet I still see the original welcome message! I've tried clearing my browsing cash and refreshing, but to no avail.
Any suggestions? Thanks.
Edit: Here's the code for controllers/test.php
<?php
class Test extends Controller {
//Just trying to get it to echo test
public function index()
{
echo "test";
//$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'm doing this tutorial here:
http://tv.cakephp.org/video/webtechnick/2011/01/12/nick_baker_--_facebook_integration_with_cakephp
I baked a new project with cake bake facebook_app and set the configuration database file to the correct settings and the default cakePHP screen showed that tmp directory was writable, DB setup was good, etc.
I downloaded the CakePHP plugin by WebTechNick here: https://github.com/webtechnick/CakePHP-Facebook-Plugin, and filled out app information (app_secret, app_id, etc), adding it to facebook_app/config/facebook.php
Changed facebook_app/app_controller.php:
class AppController extends Controller {
var $name = 'Facebook';
var $helpers = array('Session', 'Facebook.Facebook');
}
Then just exactly as in the tutorial `facebook_app/views/pages/home.ctp':
<h1>Facebook_App</h1>
<?php $this->Facebook->share(); ?>
returning the error message:
Undefined property: View::$Facebook
I realize that means PHP didn't recognize Facebook as an object. But I installed the plugin!
Also, it seems not MVCish to have something like $this->Facebook->share(); in a view (home.ctp). However, this is exactly how WebTechNick does it in his tutorial (I followed it exactly 3x) and it does not work for me. I'm a complete noob at cakePHP (although I've read the entire documentation) and I'm just trying to learn and understand through examples.
:) To be fair, it's PHP - you didn't install anything. Or if you prefer, "install" != "invoke." PHP is really amazingly easy to debug. I mean, it tells you exactly what's wrong:
Like turning to a channel that's not on the air, the error your getting means that the object you're calling doesn't actually exist, at least not in the scope you're trying to invoke it.
Is that your IDE? Is it set up for your Cake app? Are you sure the instructions were to set your AppController's $name to 'Facebook' instead of $name = Facebook_App in your AppController? It looks like you either replaced your actual app's AppController with the plugin files instead of putting them in the proper directory, or the plugin is not deferring / calling / extending / returning to the application the way it's supposed to. Knee jerk -> typo, naming conflict, path problem, permissions.
Cake's not even rendering. I can tell because your screenshot would show that error with the styled Cake errors. That tells you it's erroring before AppController class makes it to View class.
Create an instance of the Facebook object statically in the view and see what happens. Then, what does
function beforeFilter() {
parent::__construct() ?
}
get you? Anything? What about debug(), var_dump, the object functions will also shed light on what's happening. So will your logfiles.
Btw, if you don't use them already: Firefox + FirePHP + Xdebug = made of win.
I was having this problem and I found that the plugin I was using was for CakePHP 1.3 and I was using Cake 2.0. I found the BETA branch for the upgraded Cake 2.0 and it worked perfect.
Here is the Cake 2.0 BETA Branch
