[Resolved] Passing Variables from Page to Page

bakaneko

Hi,

I am new to php and I have no idea how to pass a variable from one form to another page. I used the post method with a form and sent the inputs into variables. But, when I tried to access them from the next page nothing shows up. I tried echoing the $HTTP_POST_VARS and none of my variables show up.

Can anyone help?

Thanks,

Bakaneko:eek:

yo dude

lets say you have an input field :
<input type=text name="name" >

then if you used the "POST" method, in the page that you posted it to you first you should assign a variable on that page with the value, you do this like so :

$name = $_POST['name '] (this must be the name you assigned to the field on the previous page)

then you can call the variable on that page like an ordinary var.if you were to then type :

echo " Hello there $name";

you should get a proper output.
have fun.....

I did this in my forms page

<?php

echo "<form action='Login.php?do=login' method='post'>\n
<input type='text' name = 'fname'>\n
<input type='password' name = 'fpw'>\n
<input type='submit' name = 'do' value = 'login'>\n
</form>\n";
?>

then in the login.php I tried testing it with

$password = $_post["fpw"];
echo "$password";

and nothing showed up
😕

$_POST //note CAPITAL LETTERS

Thanks! Err... another question about the top of a PHP url.
Say i have something like

http://blahblahbla/Login.php?do=login

Is the do variable defined in the Login.php? Or do I have to do the samething as before?

sempuritoza

if you pass a variable like that it applies to the page that you sent it to and you can refer to it the way you refer to variables in php, therefor you could refer to a varable posted through :

http://blahblahbla/Login.php?do=login

as $do in the page login.php

bakaneko

ahh... ok i tried that and nothing shows up. i used echo "$do";

Thanks for all the help, btw.

try

echo $_GET['do'];

i am not understanding is your problem resolved our what?

in your php.ini is your

register_globals = On \ Off

if it is off you will have to use the $_POST['var_name'] whenever you want to call a var that came from another page, you can change it by going to the php.ini either in WINDOWS or in your PHP directory but you should restart your server if you change any of these setting otherwise they wont take effect.

so when you pass the var from the other page do you get a reply now?
