Strange URL Query String issue

Postby airchie » 08. September 2010 00:02

Hi All,

I've just decided to get back into web design after a long spell away from it so I'm quite rusty.
I am going through some tutorials and have a strange issue with URL query strings I'm hoping you can help me solve.

I have a simple PHP file called welcome.php containing the following:
Code: Select all
<?php
  echo( "Welcome to our Web site, $name!" );
?>


If I open the page with the following URL:
http://localhost/welcome.php?name=john

I get the page up but only showing the following:
Welcome to our Web site, !


I've tried a few other URL query string type pages and it seems that the PHP interpreter isn't picking up the variables from the URL.
I suspect I'm missing something obvious but will be glad of any assistance.

Thanks in advance
airchie :)

Try this:

Code: Select all
<?php
  if (!empty($_GET['name'])) {
    $name = $_GET['name'];
  }
  echo( "Welcome to our Web site, $name!" );
?>


Since register_globals is set to off (and should leave deactivated because of security reasons) (Super-)global Array Keys no longer register local pendants automatically. You must take care on your variables by yourself.
