RE: [PHP] Passing form values to PHP
[snip] Anyone have any ideas as to what's up. I hope its just something silly that I'm missing being a newby to PHP and all. [/snip] There is a feature in the php.ini called register_globals. If you look in your php.ini you will see that it is off by default and some of the books may have missed this as the default previously was on. You would be best to learn PHP with it off as most of the community does it that way for various reasons. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Anyone have any ideas as to what's up. I hope its just something silly that I'm missing being a newby to PHP and all. The problem here is that the book is written for a PHP setup where register_globals is assumed to be turned on. This can be a security risk, so as of PHP 4.2.x, register_globals has been turned off by default (before it was on by default). Register globals is a directive that tells PHP to automatically create variables from requested information (be it POST or GET). More information about why register_globals is a bad idea can be found at the following PHP manual page [ http://www.php.net/register_globals ] I will include small versions of the file here for reference: [ snipped ] So I guess my question ultimately is, what are the different ways in which form data can be passed to a PHP script? Data is transferred using forms in two methods. GET or POST. The difference between the two (the main difference) is that the data from a GET request is appended to the URL. Such a request would be : http://www.google.com/search?q=php+tutorials and data from a POST request is actually sent as part of the HTTP request (in the header), so its not viewable in the browser URL. PHP provides (since PHP version 4.2) two arrays, $_POST and $_GET for each of the above methods. There is also a third array, $_REQUEST which holds all information sent in the request. These arrays are called superglobals because they are available throughout your pages without any effort from your part. Each array consists of a key and a value. The key is whatever is the name attribute of your form value. An example : form method=POST action=process.php input type=text name=firstname size=10 / input type=submit name=submit value=submit / /form process.php : ?php //Turn up error reporting //to the max level error_reporting(E_ALL); //Print out the contents //of the $_POST array //so we can see what it //contains. echo pre; print_r($_POST); echo /pre; ? When you run the above script with the associated form, you will see the format of the $_POST array. It will contain an element with the key firstname and the value will be whatever the user entered in that text box. It will also contain an element with the key submit whose value is submit (that's our submit button). Hopefully this helps, and welcome to PHP :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Passing form values to PHP
Try this: extract($_POST); extract -- Import variables into the current symbol table from an array All of my forms have worked without $_POST or $_GET. Is there a reason for inavailability of variables??? Its a good practice to use $_POST for security reasons.

When the form is submitted I want to values passed to a pop-up window.
I am aware of the need for Javascript for the pop-up window, but how do
I get the values from the form passed to the new window so I can use
them in further scripts.
I can write the javascript to do the popup window and use the onSubmit
command, but I cannot figure out how to pass the values with a regular
submit button.
Thanks
Pass them along the querystring, so that when the JavaScript popup
window opens and it goes to a certain page, those values are part of
that URL. As GET variables.
// Your PHP vars:
$var1 = 'Metroid';
$var2 = 'Metal Gear';
// Create a querystring:
$PHPqueryString = var1= . $var1 . var2= . $var2;
// echo the browser string for the popup:
print a href=\\ onclick=\openPopup(
. $PHPqueryString
. \Popup!/a\n;
// here's your JavaScript function
function openPopup(queryString)
{
var detailwindow = window.open('./target.php?' + queryString,
'windowname',
'toolbar=no,directories=no,
status=no,menubar=no,resizable=yes,
copyhistory=no,scrollbars=yes,
width=500,height=300');
detailwindow.moveTo('150', '150');
}
Now in your new script you can access these GET vars from PHP or from JS!
