I am getting this error at the time of when i hit the address bar ,
I fetch data from database and send to the view, that view's working great, but when I hit the address bar tab it shows
Symfony \Component\HttpKernel\Exception\MethodNotAllowedHttpException
any help will be great for me...
In my controller:
public function getpiece()
{
$reportno = $_POST['reportno'];
$data = DB::table('reportno')->where('reportno','=',$reportno)->get();
if(empty($data)) {
return \Redirect::to('dashboard/client/piece')
->with('status','error')
->with('message','Data Not Available');
} else {
return \View::make('dashboard.client.piecewisereport')
->with('data',$data);
}
}
It doesn't work, because when you hit enter in the address bar, it is trying to use a GET instead of a POST, but it finds only a POST route. (Route::post).
To solve this, either do:
Route::any('getpiece','Controllers\Domain\Client\ClientController#getpiece');
And then I'd advise to use something like
if (Request::isMethod('post'))
{
//
}
and
if (Request::isMethod('get'))
{
//
}
to wrap your code. More on this can be found in the Request Information docs
And an alternative method is to address the Controller directly from the routes, as can be found here: Laravel 4.2 Implicit Controllers
Note: these documentation links link to Laravel 4.2.
I notice your controller method is called getpost but your accessing the $_POST variable.
I can't tell for certain without looking at your routes file but if your route uses Route::get('routename') then it is making use of the wrong HTTP method. If this is the case try changing it to Route::post('routename').
Execute php artisan routes in a terminal from the root of your project, it lets you check what are your registered routes.
PS: FYI, in case of Laravel 5 it would be php artisan route:list

I know that for some it might be stupid or funny question (but I am newbie) but I need to find know how to properly use DD() method in laravel projects.
For example - I have got tasks to debug some code and functionality in my project (PHP laravel). And it always takes me for ever to find the exact file or folder or code where the problem is.
My mentor says to use DD() method to find things faster (but for learning purposes he didn't explain me a lot about how to actually use it and said to find out my self), but said that I should start with Route (we use backpack as well for our project). So after finding Route (custom.php file) which controller connects to my required route what should I do next? How do I implement dd() method (or as my mentor says dd('call here') method) to fast find what I should be looking for to solve my problem and complete my task? Where should I write this dd() and how should I write it?
Thank you for the answer in advance!
for example I have a:
public function create(): View
{
return view('xxxxxx. \[
//
//
\]);
}
and if I put dd() anywhere in the code, I get error message in my URL :(
first of all ,in Laravel we use dd() before return in order to read any variable.
in controller we often use two kinds of variables : collection(which we get its members via foreach) or singular variable (we get it via its name)for example:$var = 1; dd($var).
notice:
if you are using ajax response you will not be able to see dd() results in page ,you can see the result via network tab in your browser (if u inspect your page).
dd stands for "Dump and Die."
Laravel's dd() function can be defined as a helper function, which is used to dump a variable's contents to the browser and prevent the further script execution.
Example:
dd($users,$variable1,$var2);
You can use dd() in blade
#foreach($users as $user)
#dd($user)
OR
{{dd($user)}}
#endforeach
#dd($var1)
You can read this article, the have more example and comparison
https://shouts.dev/articles/laravel-dd-vs-dump-vs-vardump-vs-printr-with-example
As Laravel is following model-view-controller or MVC design pattern. First go to the route and check which controller is called in the URL with the related URL.
Then go to the controller. **dd**() function is basically a dump and die. you also can do this by **print** or **echo** function too.
Lets assume that I have a controller name ProductController where I have method name index.From where I need to show a list of products in a table.
// in controller
public function index()
{
$products = Products::all();
// here you think ,I need to check whether I am getting the output or
not.
dd( $products );
//Or echo $products;
return view ('product.list',compact('products'));
}
let's suppose you are getting everything but in view when you loop through the products you declare the wrong variable name or mistakenly do some spelling mistakes. and want to see the result.
In view just do the dd() method by the following way:
{{ dd($products) }}
I have a bit of a complicated issue. I could use some help.
I have a form that is being handled by the following function:
$module = request('module');
$classe = request('classe');
$horaire = request('horaire');
$date = request('date');
$students = DB::select('SELECT * FROM `etudiants` WHERE etudiants.id_classe = '.$classe);
return view('g_absence.absence',['module'=> $module, 'classe'=>$classe,'horaire'=>$horaire,'date'=>$date,'students'=>$students]);
I take the values $module, $class, $horaire, $date and $students and need to use them inside a different view: g_absence.absence. This works fine and when the view is returned I have access to said variables.
The issue is, inside the g_absence.absence view, I have another form that also needs to be handled, and because the url remains the same even tho a different view is returned, I cant make two posts for the same path.
web.php:
Route::get('/testboy', [App\Http\Controllers\g_absence::class,'index'])->name('marquer');
Route::post('/testboy',[App\Http\Controllers\g_absence::class, 'marquer']);
Route::post('/testboy',[App\Http\Controllers\g_absence::class, 'ajoutabsence']);
The first line is the one that send to the form page just a simple
return view
The second one handle the form in that view
The third one, I want it to handle the form inside the
g_absence.absence view, but they share the same path.
Excuse me if I'm being unclear, I'm a bit of a beginner in Laravel
your problem is using the same route for different methods
basically the first route gets executed every time you use the '/testboy' action that is why your second function never get's called.
you can solve this issue by changing your urls for example:
Route::post('/testboy-marquer',[App\Http\Controllers\g_absence::class, 'marquer']);
Route::post('/testboy-ajoutabsence',[App\Http\Controllers\g_absence::class, 'ajoutabsence']);
Or you can use one function that's handle both with one url by pathing additional parameter to your url depending on your function call :
Route::post('/testboy?type=marquer',[App\Http\Controllers\g_absence::class, 'ajoutabsence']);
in your function check the type :
if(request('type') == 'marquer') {
execute marquer logic here...
} else {
execute absence logic here...
}
Using method and path with two functionalities is wrong, but if you want to somehow use both routes my same method and path which I don't recommend you must let the request to pass through like a middleware in your first block of code Instead of return a view.
Recommended way is to have 2 routes with different paths or at least one route with a parameter by which you can determine what code block must be executed.
I'm attempting to create a custom display in yii2 framework using this code in my site controller:
/******/
public function actionChartDisplay()
{
return $this->render('chartDisplay');
}
for testing purposes I pasted the form name in my actionAbout function as a parameter to the render function in it. It worked with this:
public function actionAbout()
{
return $this->render('chartDisplay');
}
But I need to create many custom views in yii2 and this won't be a solution.
This is the error I get
I'm curious as to why it is. Since I was following this tutorial and came across this weird behaviour.
My 'chartDisplay.php' file is merely a "hello world" that does work with the action about function.
in yii2, the controllers and actions with multiple words, that are marked by capital letters are divided by - in your request, so in your case the route would be some/chart-display
Apparently as #SmartCoder pointed out it was an error on how Yii2 Handles the action functions in its controller however I didn't mark his answer as the solution right away because implementing it resulted in an error. So aside from that I'm posting the way I solved it.
So instead of using chart-display I simply changed it for "charts" like this:
public function actionCharts(){
return $this->render('charts');
}
Changed the name of my file so it fits to charts.php and it worked.
I am trying to make commenting on my site modular, so I have attempted to use view::composer to run the queries that are required to populate the comment data whenever the comment view is called, then my plan was to include the comment view in any place i needed comments, and then connect it to the appropriate comment table in my database.
The functions I have made for commenting fit each of the comment tables I've created and I've made the view composer work, the only thing is now since the function to get all the comment data is being called by the view composer when the comment view is being set up, that function no longer has access to the id that was being passed to it ( normally it is in the route like: Route::get('/{id}', 'controller#method');).
I have been searching for hours trying to figure out how to pass the variable in, but with no luck.. Maybe I'm missing some really basic detail, Idk, but I can't figure it out and haven't found anything that solves the problem, please help..
It seems like it should be so simple, I've tried doing:
$var = Route::get('/{id}', function($id){ return $id; }
Which i thought might do it, but the result was an error saying whatever the response was couldn't be converted to string.
Option 1: Access the route parameter
View::composer('comment-view', function($view){
$id = Route::current()->getParameter('id');
});
Option 2: Use the view to access the id
In your controller: return View::make('view-name')->with('commentId', $id);
View::composer('comment-view', function($view){
$id = $view->commentId;
});
I'm working on a project that allows external users(coming from another source than just my server) to make a GET request to a page on my server, which will then return some JSON encoded data.
For example, say the data (not using Cake, just standard PHP) would be sent to
wwww.example.com/handlerequest.php
I'd just have something like
if(isset($_GET['userRequest'])){
//do some stuff
echo $json_encoded_stuff;
}
With CakePHP I'd just post the data to something like
www.example.com/HandleRequest
However, I do not want/need a view for this because there is nothing to see. This page is purely for data exchange. Considering this, is there anything special I have to do so that Cake doesn't throw an error because it's expecting a corresponding view? Is this even possible?
It is easy to disable both the layout and view in CakePHP by putting the following line in your controller action:
$this->autoRender = false;
If you want to disable just the layout, use the following line in your controller action:
$this->layout = false;
And if you only want to disable the view for this action, use the following line in your controller:
$this->render(false);
Note that using $this->layout = false; and $this->render(false); together in your controller action will give you the same results as $this->autoRender = false;
