For my thesis, I am working on a program for checking cars. Currently, I am working on the user management now I have encountered the problem that the database needs to be updated when a checkbox is changed status.

Image checkboxes:

Now I have already started looking a bit on how to execute a PHP function when this happens, and I ended up with a JavaScript AJAX function

I have a list that shows results matching the user's input. The onPress of the touchableOpacity is not working in this list. This list is positioned absolutely and positioned below its parent view (positioned relative). The only time I can get the onPress to work is when I remove the top:48 style from list and the onPress works for the single element which is directly onTop of the parent.

I'm working on upgrading one of my companies projects to newer versions of MVC, Entity Framework and Unity. Most of the work has been completed however, I do have this problem when loading data from the database. This does not happen on every request and most of the application functions normally. The problem occurs on API calls the application does when there are a couple of concurrent calls.

I've tried switching the LifeTimeManager of the Unity containers to different types with different results (none of them actually fixed the problem).

This is my DataContext class

Recently I have been working to insert data into a database with laravel. Everything went fine. But know I am stuck with the error: "Use of undefined constant contacts - assumed 'contacts'". I do not know how to fix this.

I have already on the Laracast website to see if I could find an explanation on how to solve this, but I couldn't since the answers were not the once I was looking for. I have also looked in StackOverflow. But there were (again) no answers that could help me fix this the problem. I also have asked a classmate of mine but he also couldn't fix it.

My controller:

I got a problem when updating a column. I have a database with two tables this is the create statement for the tables:

I would like to retrieve data from Firebase and make User() objects within a function. I made the following class:

So I have a want to write a piece of code that get's the result out of an EntitySet and puts the data in another object by utilizing SystemReflection.

Example

Object Ticket has a property called Application, this property's value has been defined in a relation table called TicketRelation. The program has to check for the Application property in TicketRelation and if it's there it will pass the data into the Application property of Ticket.

This is what I have so far:

Hello I'm working on a website and I have students in my database table called 'jongeren' which means students. What I'm trying to do is make a list for students which are 18 years or older. In the table jongeren I have a column which is: 'geboortedatum' and that means date of birth. So I only want to echo all the students in a view that are born before 27 march 2000 but I don't know how to do that..

Right now I'm just echoing all the students like this:
