What you need is a hidden element in your form holding the value of $some_var. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] preserving variable values across pages.
You could do it a number of ways. 1. Use a hidden input field in your form,. 2. Put $some_var in a session variable. 3. Pass the value of some_var in the url. Each has it's advantages/disadvantages. Just remember that just because you say something is global doesn't mean it's global to every page, it's global on that page. global can be used as follows: If I didn't specify global $var inside the function the function wouldn't be able to "see" the $var variable I defined outside the function and would have just printed "Dude that's a " instead of "Dude that's a 1" Hope that helps.

[PHP] preserving variable values across pages.
Hi all, If I have the following code, type="submit" name="submit" value="foobar"> ?> When the user hits the submit button, the value in some_var disappears? Is there a way of perserving the value in $some_var. thanks in advance. cheers, Tehn Yit -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] preserving variable values across pages.
Found this on the php.net, querying the PHP mailing list:
">test.php
--
$blah=10;
include "whatever.php";
>whatever.php
-
echo "The value of blah is: {$blah}";
It just keeps the variable since it's global..
When ur using a function. It can be different, since you have to
import these variables."
HTH,
Andy
