Hi
If you are talking about passing a variable from one page to another, there are 2 ways to do it.

Set this variable as a hidden varaible in the form and once the form is submitted you will get the value on the next page.
Set a session/cookie variable and set this variable to hold the value of the data needed. Now this varaible is available on the next page and the other pages too.

but it's not in a form, it's simply in a

<h ref> tag ...

OKay,
this sounds like a job for Javascript, upon click set a cookie for this url, and on the other end you can check this cookie value. Once you check this cookie value, just delete it.

Hope this helps.

darn, there's no other way than a cookie?

Of course there is, simply do a
<a href="otherpage.php?var=value">click</a>

for more than one do a

<a href="otherpage.php?var=value&var2=value">click</a>

in otherpage.php you can print them with
$var and $var2

or did I misunderstand something here...

cheers

really? I seem to be doing that ...and it's not working...hmm..!?

maybe you can send me a url that does not work (ok it sort of makes sense).

I use it for example in my guestbook with php4
http://www.onlinetools.org/guestbook.php

in php3 you'll have to set the track_vars thingy though...

Try using this:

list($name,$value) = each($HTTP_GET_VARS);

it work fine and if you passed something like

url..myfile.php?var=90

it will return $name = var and $value = 90

A tip: used into a for cicle it work really fine for reading arrays.

Bye. 'hoping it's useful! (answer in mail if u want)

Is there any solution at the end ??
I also want to send the value of a variable of a php in another in order to make it appier in a field of the page.

I am experiencing the same problem!!
According to everything I have read this SHOULD WORK, but it doesn't seem to.

php ver. 4.2.1
I have had a problem with passing a variable from page to page using both the post and get form method.
I suspect I have something in my php.ini configed incorrectly. Using the default php.ini-recommended file that shipped with the tgz file.

When I use the code below I get a blank screen for processing page. I just want to see the variables pass from page to page.

Thanks for you help in advance. 8)

input page---------
<form action=authentication.php method=post>
<span class=ArticleHeadingLeft>First Name:<br></span>
<input type=text name=uname><br>
<span class=ArticleHeadingLeft>Last Name:<br></span>
<input type=password name=upass><br>
<input type=submit value=Login>
<input type=reset value=Reset>
</form>
/input page---------

processing page-----"authentication.php"
<?php
print $uname;
print $upass;
?>
/processing page-----

Beginning with PHP 4.2.0, the value of "register_globals" in php.ini is set to Off. This means that input and server variables are no longer global by default -- i.e. you can't just say $formfield for a form field input variable. Instead, variables are part of a superglobal such as $SERVER, $GET, $POST, $COOKIE, $_SESSION and so on.
Check out http://www.php.net/manual/en/language.variables.predefined.php for more info on SuperGlobals etc.

This has been done for security reasons. You have two choices:

Edit php.ini and turn register_globals on, or alternatively, use the SuperGlobals.

I found that is I redefined the variable at the top of the page it works

eg. Take the URL http://www.myserver.com/form.php?action=AddFile

On old versions of PHP this worked fine when called by say an echo statement, eg:

echo $action

What I found worked is if I added this line to the top of my form.php:

$action = $_GET[action];

I used the $_GET because the URL above shows a get method.

Hope this helps
