Sessions

[shg2001]

You have program A it calls program B,the data stored in program A should be passed to program B using session, but when program A calls program B, program B has no data.

 

Program A - Starts

 

<?php

 

session_start();

 

<code>

....

...

<code>

header("location: http://Program B.php");

 

Program B - Starts

 

<?php

 

session_start();

 

<code>

....

...

<code>

 

 

any though as to what i might be going wrong ...  as to why the data does not pass from one program to another

 

thanks

Are program a and program b on the same domain and hosting service? You include an http:// in your header() which would lead me to believe they aren't.

Also, show the part where you set the session and retrieve it.  Your code example is useless the way it is.

they are both on the domain and the same host

regarding retreiving the session.  I don't honestly know if i am doing that correctly at all.  I looked at all the documentation i could find and it all states use session_start(); at the top of each program.  But in the docs it never gives you the code for the receiving program only the sending program......  So how do u retreive the session from the sending program???

 

 

thanks

It should look something like this:

 

pagea.php

<?php
  session_start();
  $_SESSION['test'] = "I was set in Page A";
  header('Location: pageb.php');
  exit;
?>

 

pageb.php

<?php
  session_start();
  echo $_SESSION['test'];
?>

[shg2001]

so how would you send and array??

[rhodesa]

$_SESSION is an associative array in which you can assign key/value pairs. The values can be any PHP variable type.

 

<?php
  session_start();
  $_SESSION['test'] = array();
  $_SESSION['test'][] = "I was set in Page A";
  $_SESSION['test'][] = "I am another value in the array";
  header('Location: pageb.php');
  exit;
?>

 

<?php
  session_start();
  print_r($_SESSION['test']);
?>

[shg2001]

<?php

  session_start();

  $_SESSION['test'] = array();

  $_SESSION['test'][] = "I was set in Page A";

  $_SESSION['test'][] = "I am another value in the array";

  header('Location: pageb.php');

  exit;

 

<?php

  session_start();

  print_r($_SESSION['test']);

?>

 

How would you print the second element of the array "I am another value in the array";

echo "this is the second Element".$_SESSION['test'][1];
