How can I get variable to another php file?

[loremuel]

I have 3 php files.. the 1st one gives variable and the 2nd php get the variable of the 1st php but then the 3rd php cannot get the variable from the 1st php..

 

this is the variable in my 1st php file

name="field"

 

this variable will get to the 2nd php file...

$field = $_POST['field'];

echo $field;

it works to get the variable...

 

but in the 3rd php file, I code it again:

$showfield = $_POST['field'];

echo $showfield;

but it's not working...

 

please help me about my case... :'(

It was explained pretty well by PFMaBiSmAd on that link..

 

The reason why on the 3rd page you're not getting the data is because it's only posted directly to that 2nd file, if you want to have to available later on I'd use a session

 

Example:

 

1st:

name="field"

 

2nd:

session_start();

$field = $_POST['field'];

$_SESSION['field'] = $field;

 

3rd:

session_start();

$showfield = $_SESSION['field'];

echo $showfield;

Ahh.. Now I get it about why the 3rd did not get something from the 2nd.

thank you so much... 

 

There is something wrong when  I use session..

this print out in the page:
