    Default How can I Pass Variable from JApplet to PHP?

    I have tried for the whole night.
    And it is not work.
    I am familiar with php but not java.

    There are no error or any message from Java.
    I supposed that the database can connect.
    Since PHP has just received the data with simple code, so PHP should be fine.
    I guess that the problem should be on java that java did not send the variable.
    :confused:
    Java Code: 
    public class test extends JApplet {
	
	public test(){
		 JButton myButton = new JButton("sendData");
	        myButton.setFont(new Font("Sansserif", Font.PLAIN, 14));
	        myButton.setSize(15, 10);
	        
	        myButton.addActionListener(new button());
	        add(myButton);
	}
	
	
	
	private class button implements ActionListener {
        public void actionPerformed(ActionEvent e) {
        	PostMsg(10,"hello");
        }
	}
	public void PostMsg(int score, String name){
		 try {
			    // Construct data
		        String data = "name" + name + "score" + score;           
		  
		        byte[] parameterAsBytes = data.getBytes();    
  
			 
			 // Send data
			    URL url = new URL("http://localhost/addtest.php");
			    URLConnection con = url.openConnection();
			    ((HttpURLConnection) con).setRequestMethod("POST");   
		        con.setDoOutput(true);   
		        con.setDoInput(true);   
		        con.setUseCaches(false);   

			    //OutputStreamWriter wr = new OutputStreamWriter(con.getOutputStream());
		        OutputStream wr = con.getOutputStream();      

		        wr.write(parameterAsBytes);
			    wr.flush();

			   
			    }
			    wr.close();
			    rd.close();
			} catch (Exception e) {
				System.out.println("ERROR"+e.getMessage());
			}
}
	}

					There are few errors in this program.
    
I fix them.
    
Try with that code.
    
If you still have a problem, tell us about it.
     
     
     
    Java Code: 
     
    import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import java.awt.Font;

import javax.swing.JApplet;
import javax.swing.JButton;

import java.net.URL;
import java.net.URLConnection;
import java.net.HttpURLConnection;

import java.io.OutputStream;

public class WorkWithPHP {
	public class test extends JApplet {
		
		public test(){
			 JButton myButton = new JButton("sendData");
		        myButton.setFont(new Font("Sansserif", Font.PLAIN, 14));
		        myButton.setSize(15, 10);
		        
		        myButton.addActionListener(new button());
		        add(myButton);
		}
		
		
		
		private class button implements ActionListener {
	        public void actionPerformed(ActionEvent e) {
	        	PostMsg(10,"hello");
	        }
		}
		public void PostMsg(int score, String name){
			 try {
				    // Construct data
			        String data = "name" + name + "score" + score;           
			  
			        byte[] parameterAsBytes = data.getBytes();    
	  
				 
				 // Send data
				    URL url = new URL("http://localhost/addtest.php");
				    URLConnection con = url.openConnection();
				    ((HttpURLConnection) con).setRequestMethod("POST");   
			        con.setDoOutput(true);   
			        con.setDoInput(true);   
			        con.setUseCaches(false);   

				    //OutputStreamWriter wr = new OutputStreamWriter(con.getOutputStream());
			        OutputStream wr = con.getOutputStream();      

			        wr.write(parameterAsBytes);
				    wr.flush();

				   
				  //  }
				  //  wr.close();
				  //  rd.close();
				} catch (Exception e) {
					System.out.println("ERROR"+e.getMessage());
				} 
			}
	}
}
