php script help...

Hello,

I have the following php script:

test.php:

Code:

---

<?
if ($name) {
  echo $name;
}else{
  echo "No Page Name";
}
?>

---

and if you goto mysite.com/test.php?name=hello

it should display the text 'hello' on the page where the script is put but it don't work.

does anyone know why this is not working for me?

When i run it, it comes up with 'No Page Name' rather then what I put in the URL

My web server is:
Apache version: 2.2.6 (Unix)
PHP version: 5.2.5

Hope someone can help

Thanks.

You haven't shown how you are getting the $name variable, so we can't tell you anything concerning that. However, when checking for variables, you would use isset(). PHP isn't like most other languages when checking variables.

PHP Code:

---

<?php
if (isset($name)) {echo $name;}
else {echo "No Page Name";}
?>

---

the URL does not set the variable itself. You need to pull it out of the $_POST or $_GET array first.

In this case you are using GET.

Code:

---

<?php
if (isset($_GET['name'])){
$name = $_GET['name'];
echo $name;
}else{
echo "No Page Name";
}
?>

---

Thanks, I ended up using:

Code:

---

<?php
if (isset($_GET['name'])){
$name = $_GET['name'];
echo $name;
}else{
echo "No Page Name";
}
?>

---

I thought i was missing something in the code.

Thanks.

I assume you might do more than just displaying one line of text with the variable $name.
So better start with

Code:

---

$name=isset($_GET["name"])?$_GET["name"]:"No name";
echo $name;

There is a way you can do it the way of your first code, with setting register_globals on, but this is a major security risk to use.
