asta4d | View first web application framework | Model View Controller library

Im working on a onlineshop with php.

I work with the mvc model and I divide each small part of my application in: model view controller and service ( service is there for the query ).

So for example I would have a Item cart which is divided in discription and price...

For each of them I would have a seperate query, for example the discription: 'SELECT discription OF ... WHERE ...'

So my questin is:

Is there any downside ( like a worse performance ) if I use many simple MySQL queries instead of one complex query?

I have built an application that uses Spring Boot as back end and Angular as front end using APIs.

Spring Boot contains:

I am trying to implement model view controller pattern in a simple print hello world program. I can get everything to work properly except at the end after I click the button in my program. I am trying to bind my function to the controller so that way the function uses the this statements in the controller to access my model and view instances in the controller. When I click the button the this statements in my function are referencing my button object instead of the controller. I am having trouble using bind to change what the this statements point to. Please, any assistance would be greatly appreciated. thank you.

i try to add fields in a form by clicking a button. The fields appear and the validation works either. The problem is, that the value of these input fields isn't transmitted by the submit button of the form.

The framework is ASP.NET Core-Web-App (Model View Controller) with .Net 5.

I CAN'T SEND POST REQUEST FROM CLIENT SIDE !

I need to send HTTP Post request in Node js Rest API to the payment gateway. Post request needs to have headers and body payload. I have frontend and backend separated, I'm using Rest API with express.js and payment gateway needs server to server communication so I can't to do that from client side. Basically when user clicks on payment I need to send call to my backend server then my backend server needs to send request to the payment gateway.

Payment gateway has documentation with only MVC ( Model View Controller ) and they really can't help.

So logic inside controller should be something like this

First of all i am student, so i need to know how compounds Interact with each other, Maybe next time in the future i will do it with a framework, but first thing I need to do is knowing how to build the software form scratch.

My project will be web and mobile application so I decided to create a rest api for both... I will implement my project in Native PHP.

I currently have a navigation controller with 2 view controllers. After clicking Button A on VC 1, it brings me to VC 2. VC 2 has a checklist. When selecting the desired items from the checklist, I am able to select and deselect the checklist buttons. Then I click the back button on VC2 to return to VC 1. When I want to edit the checklist in VC 2, I click Button A to go back to VC 2 but the checklist has reset back to its default state and none of my selections are saved.

I have looked into Model View Controllers, Unwind Segues, UserData, Popping View Controllers but I am still very confused as to what to pick and stick to, for this to work.

Any help is much appreciated. Thanks.

I have created a blank template MVC project with user accounts in Visual Studio 2019, i.e. ASP.NET Core Web Application -> Web Application (Model View Controller), Authentication = Individual user accounts.

When you run the project, you can navigate to the pages for /Identity/Account/Register and /Identity/Account/Login. However, I can't see any reference to these pages in the project structure.

The Areas/Identity folder does not contain any controllers or views, and I can't see any custom routing which redirect Identity/Account/Register to a different controller action.

Where is the html for these pages generated?
