Laravel 5 updating the view using dropdowns - php

I have an resource controller called AppointmentsController and a model called Appointment. In my model I put a few scopes I use to filter results, like so:
public function scopeStatus($query, $statusId)
{
if($statusId)
{
return $query->where('status_id', '=', $statusId);
}
else {
return false;
}
}
I have this for month, year, label, and a few other settings. I call my query in the controller, like so:
$appointments = Appointment::latest('start')->status($statusId)->get();
All these variables ($statusId, $labelId, and so on) are set using dropdowns. Once I select another value in the dropdown, I will be redirected to my view again, with the correct value set and with the correct query.
The thing I'm struggling with how to set the $statusId (and other variables). If I use a post request I need to use an extra route (since I am using the store route from the resource route to create appointments). Which would be something like:
Route::post('appointments/whatever', 'AppointmentsController#index');
Or:
Route::post('appointments/whatever', 'AppointmentsController#whatever');
So I would fetch the $request values and then update my query accordingly, and then return the view again. Another thing I could do, is store the values in a session (not my preferred way). I could also update the values in the database, then go back to the index method, grab the results from the database and then update my view again.
Any thoughts how I should go about doing this? I can get it to work the amateuristic way but I want to learn how to do this in a proper manner, maybe there is even something I haven't thought of yet or maybe even my code is not good enough. Anything that helps me go in the right direction will answer my question.

Laravel : form does not change the URL after submit, causing me to be unable to do another POST in web.php

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.

after using where condition with parameter Css is not working in laravel

I am trying to list database details using where condition with parameter after calling this function CSS not working but all data is list down properly and without parameters, CSS working properly.
web.php
Route::get('/viwelist/{id}','Front\SISProfileController#check');
controller
class SISProfileController extends Controller
{
public function check($district){
$list = SISAccount::all()->where('District', '==', $district);
//dd($list->all());
return view('Front.listSIS', compact('list'));
}
}
link
click
What you are doing is getting all the elements from the database and the checking that condition through Collection::where method, and this will cause a lot of problem if in the database there're a lot of data. Instead you should use the where method directly on the database, and than get back only those records, so you should do something like:
$list = SISAccount::where('District', '=', $district)->get(); //to get back a Collection with all the records
$list = SISAccount::where('District', '=', $district)->first(); //to get only the first record, like if District is your primary key
The css problem is probably caused by the fact that you have put a relative link on your header as position of the css file, instead you should have something like /asset/css.css, so with a / at the beginning

passing variable through controller method attatched to view::composer in Laravel

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;
});

How to access values of multiple parameters passed to Laravel controller

I am trying to figure out how to access two (or more) parameters passed to a Laravel controller. I know how to create the route, and the URL is created correctly, but then I can only access the first passed parameter in my controller.
Route:
Route::get('managers/{id}/{parameter2}', array('as'=>'dosomething', 'uses'=> 'ManagersController#dosomething'));
where the first parameter is obviously the $id for managers, and the second parameters is to be processed by the controller.
View:
Do Something
generates the URL:
http://domain/managers/1/2
where 1 is easily accessed as the $id for managers, but when I try to access the 2nd parameter "2" using $parameter2, e.g. using a simple return: "id=$id and parameter2=$parameter2" statement, I get an "unidentified variable: $parameter2" error.
What am I doing wrong?
Is there a better way to pass multiple parameters? I'm especially asking the "better way?" question because what I want to do is use the 2nd parameter to change a value in a database table, and using a 'get' method, somebody could change the parameter value in the URL and therefore cause mischief. Must I use a 'post' method? I'd love to be able to use a link, since that works much better with the design of my application.
Thanks!
I was asked to include the controller, which I'm happy to do. Initially, just for testing, as I mentioned, my controller was a simple return to display the values of the two passed parameters. But here is what I want to be able to do, including the actual name of the function ("update_group" rather than "dosomething") --
ManagersController:
public function update_group($id)
{
DB::table('groups')->where('id','=',$parameter2)->update(array('manager_id'=>$id));
return Redirect::route('managers.show', array('id'=>$id));
}
The update table works perfectly if I replace $parameter2 with an actual value, so that syntax is fine. The issue is that Laravel says that $parameter2 is an undefined variable, despite the fact that the URL contains the value of $parameter2 as you can see above.
And since it occurs to me that the answer to this may involve adding a function to the Manager model, here is the current
Manager.php
class Manager extends Eloquent {
protected $table = 'managers'; ... (mutator and error functions)
}
Just change
public function update_group($id)
to
public function update_group($id, $parameter2)
All looks ok in your route. Seeing the controller code would help, but likely, you may not have a second parameter in your controller's dosomething() method.
public function dosomething($id, $parameter2){
var_dump($id).'<br />';
var_dump($paremter2);
}
If that isn't the case, you can try dumping it from the route's callback to further diagnose.
Route::get('managers/{id}/{parameter2}', function($id, $parameter2)
{
var_dump($id).'<br />';
var_dump($paremter2);
});
Depending on your use case, you can pass them in a query string like so: but it isn't really the 'best way', unless you're doing something like building an API that won't use the same variables in the same order all the time.
/managers?id=1&paramter2=secondParameter
var_dump(Request::query('id')).'<br />';
var_dump(Request::query('paramter2'));

Passing two arrays from controller in cakePHP

I'm trying my best to learn MVC and cakePHP and I had a question about passing arrays to the view. Currently, I have some basic code below.
class AwarenesscampaignsController extends AppController {
public function view($id = null) {
$this->Awarenesscampaign->id = $id;
$this->set('data', $this->Awarenesscampaign->read());
}
This is what I "think" is currently happening.
AwarenesscampaignsController is set up. The view paramater requests id and matches it up with the Model, Awarenesscampaign. This matches up with the database and returns an array which is set to the variable "$data", and then the view is loaded.
My first question: is my understanding accurate?
What I would like to do is with this is to be able to pass another array, from a different model. For instance, I would like to query the table Posts (Controller: PostsController/ Model: Post).
For instance, my first attempt was to do the following inside the function:
$this->Post->find('all');
But this yields the error:
Indirect modification of overloaded property AwarenesscampaignsController::$Post has no effect [APP/Controller/AwarenesscampaignsController.php, line 20]
Additionally, I'm not sure how I would send both variables to the view.
To recap:
Was my understanding accurate?
How do I query a variable from another controller/model?
How do I sent this array to the appropriate view for that controller?
Thanks,
-M
You're on the right lines, and aren't doing it wrong per se. I would say your understanding is pretty good for a beginner.
By default Cake automatically loads a model that it thinks is directly related to the controller. So in AwarenesscampaignController, you can automatically access Awarenesscampaign (the model).
It doesn't know about any other model, though. One way you might solve this is by adding the following property to your controller:
// This has to contain ALL models you intend to use in the controller
public $uses = array('Awarenesscampaign', 'Post');
This goes at the top of the class, before you start declaring the functions. It tells Cake that you want to use other models except the 'default' one, but you have to add that one to the array too, or you'll lose access to it.
You can also use loadModel inside your action, if it's a one-off. It's then accessed the same way as you would access a model normally:
public function view($id = null) {
$this->loadModel('Post');
$posts = $this->Post->find('all');
...
}
To send this to your view, you can call set again, but you might want to change data to something more readable, and to prevent confusion:
public function view($id = null) {
...
$this->set('campaign', $this->Awarenesscampaign->read());
$this->set('posts', $this->Post->find('all'));
}
They'll be accessible as $campaign and $post respectively.
One tweak I would make, though, is to not use 'read' unless you intend to edit something. You can use findByColumnName to get the same data. Since you're using just an id, you can call findById:
$campaign = $this->Awarenesscampaign->findById($id);
There's quite a lot of magic going on there. It just means you can search for a particular value in a more short-hand format.
http://book.cakephp.org/2.0/en/models/retrieving-your-data.html
Finally, while you can access other models (as demonstrated), you can't, or generally shouldn't, try and access one controller from another. If you have code that you want to use in more than one controller, but can't go in the model, you can create Components.
http://book.cakephp.org/2.0/en/controllers/components.html#creating-a-component
The manual is fairly comprehensive. While sometimes hard to navigate, it will often have an answer to most of your questions.
http://book.cakephp.org/2.0/en/
1) Your understanding is good enough. What this is doing is basically mapping a row of database table with object. So after setting the Model id $this->Awarenesscampaign->id = $id, now Model is pointing to the row of database table that has id equals to what has been passed to view action.
2) you can query another table by calling the methods of that particular Model. If your model is somehow associated with the current Model that you are in, you can use chaining to call that Model's action. e.g. if your in Posts controller and Post Model is associated with Comment Model t get the data you can chain through.
$comments = $this->Post->Comment->find();
If however your Model of interest is not associated with current Model, there are couple of ways to perform operations of other Model. A good option is to use Class Registry. Say for example you want to use Customer Model which is not related to your current Model. In your controller you will do
$customer= ClassRegistry::init("Customer");
$customers= $customer->find();
3) to set multiple variables for the view you can set them via compact function or using associated row.
$posts = $this->Post->find();
$comments = $this->Post->Comment->find();
$this->set(compact('posts', 'comments'));
// or
$this->set('posts' => $posts, 'comments' => $comments);
