How to pass variables between php scripts?
To pass info via GET:
header('Location: otherScript.php?var1=val1&var2=val2');Session:
// first script session_start(); $_SESSION['varName'] = 'varVal'; header('Location: second_script.php'); // go to other // second script session_start(); $myVar = $_SESSION['varName'];Post: Take a look at this.
You should look into session variables. This involves storing data on the server linked to a particular reference number (the "session id") which is then sent by the browser on each request (generally as a cookie). The server can see that the same user is accessing the page, and it sets the $_SESSION superglobal to reflect this.
For instance:
a.php
session_start(); // must be called before data is sent$_SESSION['error_msg'] = 'Invalid input';// redirect to b.phpb.php
<?phpsession_start();echo $_SESSION['error_msg']; // outputs "Invalid input"
