Passing data from blade to blade in Laravel - laravel

I have a page where you can create your workout plan. Second page contains "pre-saved" workouts and I want them to load by passing parameters from second page to first. If you directly access first page, you create your workout plan from scratch.
// first page = https://prnt.sc/y4q77z
// second page = https://prnt.sc/y4qfem ; where you can check which one you want to pass to first page
// final step looks like this: https://prnt.sc/y4qh2q - but my URL looks like this:
www.example.com/training/plan?sabloni%5B%5D=84&sabloni%5B%5D=85&sabloni%5B%5D=86
this 84,85,86 are IDS
Can I pass params without changing URL ? Like having only /training/plan without anything after ?
public function plan(Request $request){
$workout = false;
if($request->workout){
$workout = $request->workout;
$workout = SablonTrening::find($sabloni); // $workout = array [1,3,4,5,6]
}
return view('trener.dodaj_trening', compact('workout'));
}

If you are getting to the /training/plan page with GET request, you could simply change it to POST. That way the parameters would be hidden in the URL but would be present in the request body. You would need a new post route:
Route::post('/training/plan', 'YourController#plan')->name('training.plan');
And then, in the form where you are selecting these plans, change the method on submit:
<form action="{{route('training.plan')}}">
//Your inputs
</form>
Your method should still work if your inputs stay the same.
Note: Not sure you would still keep the functionalities that you need, since I can't see all the logic you have.
If you have any questions, let me know.

To pass data from on blade to another blade.
At the end of first post before redirect()-route('myroute') add $request->session()->put('data', $mydata);
At the begining of the route 'myroute', just get back your data with $data = $request->old('data');

Stumpped trying to pass two parameters from view form to controller

I have a Laravel 6 app and am trying to pass two parameters from my view's form to my controller via a resource route. I can pass one, no problem, but passing two gives the same error:
Too few arguments to function App\Http\Controllers\Admin\SubscriptionsController::update(), 1 passed and exactly 2 expected
I've tried many different arrangements suggested from other posts but none bring the desired result.
Here's my route:
Route::resource('subscriptions', 'Admin\SubscriptionsController')
Here's my form in my view:
{{ Form::open(['route' => ['admin.subscriptions.update', $plan->id, $coupon_code], 'method' => 'PUT', 'id' => 'role-' . $plan->id, $coupon_code]) }}
Coupon Code: <input type="text" name="coupon_code">
{{ Form::close() }}
Here's my controller. It doesn't reach the dd() test.
public function update($id, $coupon_code)
{
dd($coupon_code);
...
In the error Whoops! page, I can see the POST DATA that $coupon_code is being sent over.
However, if I remove the $coupon_code parameter from the controller (leaving public function update($id) ) it functions fine passing $id from form to controller, but I don't get the $coupon_code data I need to process. Adding the second parameter bombs it.
Any suggestions are very welcome.
As you are using the resource controller, it won't allow you to pass additional fields directly to its update() route. Instead, you have to override the update route.
Here is how you can do it, Immediately below your resource.
You can add a new route as below:
// web.php
Route::resource('subscriptions', 'Admin\SubscriptionsController')
// Make sure you add name when you are overriding the route
Route::put('subscriptions/{subscription}/{coupon_code?}', 'Admin\SubscriptionsController#update'])->name('admin.subscriptions.update');
I believe you won't be sending the coupon code every time so you can add {coupon_code?} which becomes optional.
In you controller's update() method, make the coupon_code optional
public function update($id, $coupon_code = null)
{
...
}
You can not add a new param for Route::resource. If you really want to take 2 params, you should create a new route.
for an example:
Route::resource('subscriptions', 'Admin\SubscriptionsController')->except('update');
Route::put('/subscriptions/{id}/{coupon_code}', 'Admin\SubscriptionsController#update')->name('subscriptions.update');
But I think it's better not using method params. Why not just using input form?
so we can process the coupon code like this:
request()->coupon_code;

Laravel Pagination on POST request

Im using Laravel v7 and i have a question about pagination.
So far im using 2 routes, 1rst to return a view with all rows from database, and 2nd receives an input and returns that view with the rows filtered by that input value.
But im using pagination, and on the 2nd route, when i try to go to 2nd page it gives me an error:
Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException
The GET method is not supported for this route. Supported methods: POST.
I've tried to change my form method to GET but i need that the token doesn't appear on the page URL and beside that, when i go to 2nd page, it returns all the rows again.
Thats my code so far:
Routes:
Route::get('concessions', 'ConcessionController#index')->name('concessions.index');
Route::post('concessions/search', 'ConcessionController#search')->name('concessions.search');
Controller
class ConcessionController extends Controller
{
public function index()
{
$concessions = DB::table('concessions')->paginate(12);
return view('admin.concessions.index', compact('concessions'));
}
public function search(Request $request)
{
$name = $request->name;
$concessions = Concession::where('name', 'like', '%' . $name . '%')->paginate(12);
return view('admin.concessions.index', compact('concessions', 'name'));
}
}
Any way to do that?
Laravel pagination only works with get parameters.
You should use GET method for your search page. POST requests aren't meant for the purpose of displaying data. Why? There are many reasons, but to be short I will give you three examples :
1. When you access the first page, you get the data by GET request,
not POST request. So if you want to use POST request, you
need to access the page as POST request by sending data with
POST method.
2. With GET parameters, let's say you are on 5th page - you can
copy the link and paste it to friend and he will be able to view
the same content as you. With POST this is impossible.
3. You can not use back button with POST requests, if you manage to
get pagination to work.
POST requests are useful when you need to submit data to the server, in order to create new record, for example.
So I suggest you to change your route type to GET.
From my perspective, if you change your route code similar to below code, it will work properly with both methods of GET and POST.
Route::any('concessions/search', 'ConcessionController#search')->name('concessions.search');

Lumen Blade result to array gives empty value

When I put the following code in my controller in Lumen it returns an empty value for the 'info' key, which should contain the Blade template:
$return = array();
$return['cities'] = $cities;
$return['info'] = view('popup/dialog')->with('result',$result);
return $return;
This returns the following
{"cities":["Den Helder"],"info":{}}
But when I only return the 'info' value, it will show the Blade template
return $return['info'];
I'm using this implementation in an websocket environment. I want to keep the websocket calls to a minimum. So it would be great to return the contents of the template, within the dataset.
Hope you can help.
Offtopic: I'm reading for a couple of years on this site, but this is my first post. If I'm doing something wrong, please tell me.
Thanks in advance!
You need to use the render() method to generate the HTML content of you view.
This should work:
$return['info'] = view('popup/dialog')->with('result',$result)->render();

How to Remove/Register Suffix on Laravel Route?

EDIT: See below for my current problem. The top portion is a previous issue that I've solved but is somewhat related
I need to modify the input values passed to my controller before it actually gets there. I am building a web app that I want to be able to support multiple request input types (JSON and XML initially). I want to be able to catch the input BEFORE it goes to my restful controller, and modify it into an appropriate StdClass object.
I can't, for the life of me, figure out how to intercept and modify that input. Help?
For example, I'd like to be able to have filters like this:
Route::filter('json', function()
{
//modify input here into common PHP object format
});
Route::filter('xml', function()
{
//modify input here into common PHP object format
});
Route::filter('other', function()
{
//modify input here into common PHP object format
});
Route::when('*.json', 'json'); //Any route with '.json' appended uses json filter
Route::when('*.xml', 'xml'); //Any route with '.json' appended uses json filter
Route::when('*.other', 'other'); //Any route with '.json' appended uses json filter
Right now I'm simply doing a Input::isJson() check in my controller function, followed by the code below - note that this is a bit of a simplification of my code.
$data = Input::all();
$objs = array();
foreach($data as $key => $content)
{
$objs[$key] = json_decode($content);
}
EDIT: I've actually solved this, but have another issue now. Here's how I solved it:
Route::filter('json', function()
{
$new_input = array();
if (Input::isJson())
{
foreach(Input::all() as $key => $content)
{
//Do any input modification needed here
//Save it in $new_input
}
Input::replace($new_input);
}
else
{
return "Input provided was not JSON";
}
});
Route::when('*.json', 'json'); //Any route with '.json' appended uses json filter
The issue I have now is this: The path that the Router attempts to go to after the filter, contains .json from the input URI. The only option I've seen for solving this is to replace Input::replace($new_input) with
$new_path = str_replace('.json', '', Request::path());
Redirect::to($new_path)->withInput($new_input);
This however leads to 2 issues. Firstly I can't get it to redirect with a POST request - it's always a GET request. Second, the data being passed in is being flashed to the session - I'd rather have it available via the Input class as it would be with Input::replace().
Any suggestions on how to solve this?
I managed to solve the second issue as well - but it involved a lot of extra work and poking around... I'm not sure if it's the best solution, but it allows for suffixing routes similar to how you would prefix them.
Here's the github commit for how I solved it:
https://github.com/pcockwell/AuToDo/commit/dd269e756156f1e316825f4da3bfdd6930bd2e85
In particular, you should be looking at:
app/config/app.php
app/lib/autodo/src/Autodo/Routing/RouteCompiler.php
app/lib/autodo/src/Autodo/Routing/Router.php
app/lib/autodo/src/Autodo/Routing/RoutingServiceProvider.php
app/routes.php
composer.json
After making these modifications, I needed to run composer dumpautoload and php artisan optimize. The rest of those files are just validation for my data models and the result of running those 2 commands.
I didn't split the commit up because I'd been working on it for several hours and just wanted it in.
I'm going to hopefully look to extend the suffix tool to allow an array of suffixes so that any match will proceed. For example,
Route::group(array('suffix' => array('.json', '.xml', 'some_other_url_suffix')), function()
{
// Controller for base API function.
Route::controller('api', 'ApiController');
});
And this would ideally accept any call matching
{base_url}/api/{method}{/{v1?}/{v2?}/{v3?}/{v4?}/{v5?}?}{suffix}`
Where:
base_url is the domain base url
method is a function defined in ApiController
{/{v1?}/{v2?}/{v3?}/{v4?}/{v5?}?} is a series of up to 5 optional variables as are added when registering a controller with Route::controller()
suffix is one of the values in the suffix array passed to Route::group()
This example in particular should accept all of the following (assuming localhost is the base url, and the methods available are getMethod1($str1 = null, $str2 = null) and postMethod2()):
GET request to localhost/api/method1.json
GET request to localhost/api/method1.xml
GET request to localhost/api/method1some_other_url_suffix
POST request to localhost/api/method2.json
POST request to localhost/api/method2.xml
POST request to localhost/api/method2some_other_url_suffix
GET request to localhost/api/method1/hello/world.json
GET request to localhost/api/method1/hello/world.xml
GET request to localhost/api/method1/hello/worldsome_other_url_suffix
The last three requests would pass $str1 = 'hello' and $str2 = 'world' to getMethod1 as parameters.
EDIT: The changes to allow multiple suffixes was fairly easy. Commit located below (please make sure you get BOTH commit changes to get this working):
https://github.com/pcockwell/AuToDo/commit/864187981a436b60868aa420f7d212aaff1d3dfe
Eventually, I'm also hoping to submit this to the laravel/framework project.

filter a string to remove disallowed characters to compose an URL in CodeIgniter

I'm trying to make URL-friendly links for the blog on my portfolio.
So I would like to obtain links something like site/journal/post/{title}
Obviously Journal is my controller, but let's say my title would be 'mysite.com goes live!' I would like to have a valid url like site/journal/post/mysitecom-goes-live where all disallowed characters are removed.
How would I transform 'mysite.com goes live!' to 'site/journal/post/mysitecom-goes-live' in CodeIgniter based on the characters in $config['permitted_uri_chars']
use the url helper
$this->load->helper('url');
$blog_slug = url_title('Mysite.com Goes live!');
echo $blog_slug //mysitecom-site-goes-live
// might differ slightly, but it'll do what you want.
to generate url-friendly links.
Store this value in a field in your blog table (url_title/url_slug) whatever.
make a function:
class Journal extends controller
{
//make your index/constructor etc
function view($post)
{
$this->blog_model->get_post($post);
// etc - your model returns the correct post,
// then process that data and pass it to your view
}
}
your blog_model has a method get_post that uses CI's
$this->db->where('url_title', $post);
hope that makes sense.
then when you access the page:
site.com/journal/view/mysite-goes-live
the function will pick up "mysite-goes-live" and pass it to the view() function, which in turn looks up the appropriate blog entry in the database.
