Can't pass PHP parameters

Al_Link

I had a simple PHP application that used parameters passed through the URL to be used with the page's script. Everything worked fine... until I transferred my site to a different web host. The internal PHP code works okay, but all the parameters are passed as blanks. For example, in this simple example, the variable "$test" is always blank (it used to work fine on my old server).

http://www.domain.com/testpass.php?test=1234

<title>PHP Information</title>
<?php
print ("This was passed as the 'test' parameter: ");
print ("$test");
?>

What am I missing? Is there a PHP server setting that is preventing this from working correctly?

Thanks for your expertise!

yes, this server has register globals set to off (as it is by default). That means to access a variable in your url, you have to use the superglobal $_GET

in your case

echo $_GET['test'];

All form variables with a method of post must be accessed using the superglobal $_POST

Your echo $_GET['test']; suggestion did the trick -- thanks!

Is there a generic PHP routine or function I can use that will "pick up" each field without having to know the individual field names?

cgraz

field names for what? a database?

maybe something like that ? (it works with $_POST , too)

echo "Values submitted via GET method:<br />\n";
reset ($_GET);
while (list ($key, $val) = each ($_GET)) {
    echo "Variale $key contains value  $val<br />\n";
}

I'm thinking of a generic PHP routine that would scan the URL and assign the passed parameters to fields within the PHP code. For example...

http://www.domain.com?person=john&class=english&grade=B

... would assign the fields:

$person = "john";
$class = "english";
$grade = "B";

Or you could do it like this... (my personal favorite way)
try using the $QUERY_STRING;

echo $QUERY_STRING;

You can split it and whatever you want.

here is what I do... which works just as well and assigns whatever is after an equal sign to the prior... er.. well look..

whatever.com/index.php?variable=value&this=that

What it will do is make variable contain value, and this contain that... (all variables) so you can easily do so.

$query = $QUERY_STRING;
$query_Array = explode("&", $query);
foreach ($query_Array as $i) {
$doubleItem = explode("=", $i);
$$doubleItem[0] = $doubleItem[1];
}

Its actually quite easy, now you can just call variables like this, if you had the address index.php?variable=value&this=that

you could just call the variables like normal if you would know the name... such as...

echo $variable;
that would return "value",

echo $this;
that would return "that"

Pretty easy eh? hehe...
