Variables

dlc2000

hi,
how can i print the value of the $fare variable on a other page??

if($errore==0) {
$fare = "";
if($modo==0) $fare = "registrare";
elseif($modo==1) $fare = "trasferire";
?>

maybe i need to move it like a hidden value?

thank you

michael

<? echo '<a href=mypage.php?fare=' .$fare. '>Fare Page</a>'; ?>

No entiendo el que usted esté haciendo.

you have four basic options:

1.)use sessions/cookies
2.)use GET method (form or in URL)
3.)use POST method (form only)
4.)store in some physical medium and access it later (ie: database, file...)

The first three more or less store your variable in memory. The fourth one uses some help from the OS/third party.

There are lots of questions about forms and sessions.
Using sessions is pretty easy, try looking it up in the manual.
www.php.net

it's basically like this (depending on your PHP configuration):

first.php

<?php
session_start();
session_register("fare");

$fare = "hello world";

second.php

<?php

echo $fare;
?>

Depending on your configuration, using sessions depends on cookies though...

Not everyone likes cookies. Depends on the application.

how can i do with Get method URL?

thx

jeremuck

what he showed you. with the ?

in fact, the url to access this very page has variables in it.
It's using the GET method.

there are many questions about it on this forum.

in fact, here:

I've explained exactly what you want to do: pass a variable from one page to another.

i link the other page with the form so i think that i can get the value by : $_POST[var]

but how can i use it??

jeremuck

that's using the POST method

your form page should look like this:

<form method=POST action=secondpage.php>
<input name=mytext value=""><br>
<?
if($errore==0) { 
$fare = ""; 
if($modo==0) $fare = "registrare"; 
elseif($modo==1) $fare = "trasferire"; 

echo "<input type=hidden name=\"fare\" value=\"" . $fare . "\">\n";
?>
<input type=submit name=submit value=submit>
</form>

==================

secondpage.php

<?php
echo $fare;
echo $mytext;
?>

or
secondpage.php

<?php
echo $_POST['fare'];
echo $_POST['mytext'];
?>

or
secondpage.php

<?php
echo $HTTP_POST_VARS['fare'];
echo $_HTTP_POST_VARS['mytext'];
?>

it depends on your configuration
also, you should test to see ifyou actually have valid information before you just start using it...
