Javier's questions

The first is executed first and is responsible for reading the html to save data in a two-dimensional array (javascript), but before saving the data in the arraydesire to validate it if it is nullempty ( so far without problems).

For this one asynand await. As there are several columns to save in my arrayuse several await to validate data by data , but my problem is that only awaitthe first validation works and the software does not advance further.

This is my first function:

for(var a=0;a<elementos_variantes.length; a++)
{
    datos[a]= new Array();
}

// Recopilacion de datos
for(var b=0;b<elementos_variantes.length; b++)
{
    datos[b][0]=await validar_datos($("." + elementos_variantes[b] +  '.select_bodega').val());
    datos[b][1]=await validar_datos($("." + elementos_variantes[b] +  '.select_producto').val());
    datos[b][2]=await validar_datos($("." + elementos_variantes[b] +  '.select_variante').val());
    datos[b][3]=await validar_datos($('.ca' + elementos_variantes[b]).val());
}

This is the function that validates data by data:

function validar_datos(dato)
{  
    return new Promise(resolve => {
        if(dato=='undefined' || dato==null || dato=="")
        {
            Swal.fire({
                icon: 'error',
                title: 'Informacion',
                text: 'Llene todos los datos.'
            });

            return;
        }
        else
        {
            return dato;
        }
    });
}

As I mentioned before , it only does the first validation even though the first data to be validated is neither null, undefinednor empty , it only validates this:

datos[b][0]=await validar_datos($("." + elementos_variantes[b] +  '.select_bodega').val());

and there it stops and does not continue with the following validations.

Photo of all my migrations.

Photo of Error in console:

I am trying to validate that the data selected from a select is in the "categories_condominiums" table and in the "category" column since the user could change the html code, I do it with this FormRequest rule:

'categoria_condominio' => 'in:categorias_condominios,categoria|required',

And this is the table where it does the condo_categories check:

But whichever one I choose, it gives me the error:

Mistake! The selected condo category is invalid.

When trying to get records from a table I get this error:

I'm trying to list files from directories but it seems like the directories are empty:

     File dir = Environment.getExternalStorageDirectory();
    String path = dir.getAbsolutePath();

    File carpeta = new File(path);
    String[] listado = carpeta.list();
    if (listado == null || listado.length == 0) {
        Toast.makeText(this, "No hay elementos dentro de la carpeta actual", Toast.LENGTH_SHORT).show();
        System.out.println("No hay elementos dentro de la carpeta actual");
        return;
    }
    else {
        for (int i=0; i< listado.length; i++) {
            System.out.println(listado[i]);
        }
    }

I have checked the directories and if they have files, it is internal memory and the app also has the permissions. I got it by giving Storage permissions manually, is there a way to automate it?

Hello, install Prestashop 1.7.6 on my PC (localhost) and everything worked perfectly, but I uploaded it to Digital Ocean and when entering the root folder of the store it returns to localhost.

Example:

Enter http://68.224.12.144/prestashop and it automatically redirects to http://localhost/prestashop

I have an ArrayList of objects of a class but I don't know how to access the information of the ArrayList.

class Personas
{
    string nombres ="";
    string apellidos ="";

    public Personas(string nombres,string apellidos)
    {
        this.nombres = nombres;
        this.apellidos = apellidos;

    }
}

private void button3_Click(object sender, EventArgs e)
{
      Personas personas;
      ArrayList lista;

      Personas personas = new Personas("BYRON","RAMIREZ");
      lista = new ArrayList();
      lista.Add(personas);

      MessageBox.Show(personas[0]["nombre"]);
}

I get an error when displaying the information.

I try to get the rows but without duplicates, I try to filter the duplicates by the "date_payment" column.

$datos = DB::table('quincenas')->distinct('fecha_pago')->get();

return view('employees\reports\fortnights')->with('data',$data);

Also tried like this:

$datos = DB::table('quincenas')->distinct()->get();

return view('employees\reports\fortnights')->with('data',$data);

Result:

We know that a class that extends from Threadhas a method run()which is an independent thread, but how can I have several threads in a single class?

For example, if I have a class Jugadorand it has 2 methods (run, shoot), how can I make those 2 methods independent threads in 1 same class. Or you would have to create 2 classes, one for running and one for firing, because you can only have one method run().

Main

package hilos;

public class Hilos {

public static void main(String[] args) {


    acciones accion1 = new acciones();
    accion1.start();

}

}

Class with Threads

package hilos;

public class acciones extends Thread {

@Override
public void run()
{

// Código para correr 

} 

// Código para correr para nadar ????????????? como seria ??
