It's not too difficult. Say you had a login page with two text areas (username and password) and a button (submit) you would use an HTML form like this...
Post (method="post") the html control data e.g. txtusername, txtpassword to your php page. Then on your php page you need to start_session() (or something like that) and then assign a value to the session variable e.g. $_SESSION = $_POST[txtusername].
Now you can access that variable while the session is live.
e.g.
<?php
echo $_SESSION['varUserName'] //output user name
?>
Thanks. So you mean you set the system up as normal: e.g. Apache, PHP, MySQL etc and then just configure the system so that it doesn't serve incomming requests?
Hi, is it possible to set up a PHP development environment on a home PC. I assume you still need web server software, however, i only want it to practice my PHP coding and not open up my system to the Internet. I hope that makes sense.
Anyway if someone could point me in the right direction, thanks.
Hi, can anyone recommend me a good text book with information about setting up an online business with content such as methods of financial transaction, search engine optimization, web business models, etc.
I don't know if you can do it but it might be possible to display images using the <marquee> tags and maybe hyperlink them to some kind of popup window.
The class calling the method needs a reference to the other class. For example, ClassA instantiates ClassB (Below) and ClassB needs to call a method provided by ClassA. The 'this' keyword can be passed into ClassB's constructor to provide it with a reference to ClassA.
E.g.
public class ClassA{
ClassB subordinate;
public static void main(String[] args){
subordinate = new ClassB(this);
}
public void mymethod(){
//do something
}
}
public class ClassB{
ClassA master;
public ClassB(ClassA master){
this.master = master;
master.mymethod();
}
}
It seems strange that Applets aren't so popular, as Java is a popular programming language. But i've never used flash so i couldn't really compare why you would choose one over the other.
I just created the getImage method and called it to place the image. With the code below you would have packed the jar with a folder containing 'myimage'. This code should work from a Jar.
import java.awt.*;
import javax.swing.*;
import java.net.URL;
public class JarImage
{
public JarImage()
{
JFrame frame = new JFrame();
JButton button = new JButton
(new ImageIcon(getImage("images/myimage.gif")));
frame.getContentPane().add(button, BorderLayout.SOUTH);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(600, 500);
frame.setLocation(300, 100);
frame.setVisible(true);
}
private Image getImage(String pathName)
{
URL url = getClass().getResource(pathName);
Image image = Toolkit.getDefaultToolkit().getImage(url);
return image;
}
public static void main(String[] args)
{
JarImage jar = new JarImage();
}
}
Hi, i'm using a JTextPane that i've customized with a method to set up some tabstops. In my GUI class constructor i call the tabstop setup method and it works fine.
I'm having a problem though when i load text into the TextPane. Even though i call the tabstop setup method it doesn't seem to work. Anyone seen this before?
Thanks for the reply but i can't get it to work. When i use this i can run it through the IDE but when i try to run the jar the application won't even load. I've made sure that the manifest has the main class.
I can't seem to get access to images in my application when i pack the executable jar file. I've tried everything i can find in examples and nothing is working.
Can anyone help please?
Is there a way of specifying where images are in the manifest file.
Hi, i've got a component that displays two JSpinners with a JOptionPane but the JSpinners are stretched across the dialog window. Does anyone know how i can format the JSpinners so they're smaller?
Here's some of the code
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;
public class TComponent
{
private SpinnerNumberModel spinnerModel1;
private SpinnerNumberModel spinnerModel2;
private JSpinner spinner1;
private JSpinner spinner2;
private JOptionPane optionPane;
private JDialog dialog;
private JFrame frame;
public TComponent(JFrame frame)
{
this.frame = frame;
spinnerModel1 = new SpinnerNumberModel(5, 1, 30, 1);
spinnerModel2 = new SpinnerNumberModel(5, 1, 30, 1);
spinner1 = new JSpinner(spinnerModel1);
spinner2 = new JSpinner(spinnerModel2);
Object[] message = {"Spinner 1: ", spinner1,
"Spinner 2: ", spinner2};
Object[] options = {"OK", "Cancel"};
optionPane = new JOptionPane(message,
JOptionPane.PLAIN_MESSAGE,
JOptionPane.OK_CANCEL_OPTION,
null, options);
dialog = optionPane.createDialog(frame, "Spinners");
dialog.show();
}
public static void main(String[] args)
{
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(600, 500);
frame.setLocation(300, 300);
frame.setVisible(true);
TComponent op = new TComponent(frame);
}
}
JFileChooser has a setFileFilter(FileFilter filter) method. I could call this by putting any of my custom filters in but i don't have an identifier for the default one. So basically i'm just wonding what the default identifier is.
Hello. I'm using a JOptionPane to display some application information when the user selects the Help-About menu option.
If the about option has been selected and you click on an alternative application (e.g. a browser) when you return to the application the JOptionPane is lost and the application can't continue. You basically have to shut it down.
Any suggestions how i can keep the JOptionPane visible over the application?
Hi, i have a jtextpane and a JComponet that displays line numbers. Does anyone know how i can get the startline and end line of the text that is currently in view on the JTextPane?
