How to pass parameters from one page to the next? 1

[Apollo6]

I have the following code where I execute a query on the first page. If it returns a certain value, I want to redirect to another page and pass along the parameters from the first page, else keep executing the first page.

Any help would be great. Please let me know if I have not included enought information to determine my problem.


//Supervisor Check...
$sup_query = "SELECT supervsr
FROM
emptable
WHERE
(((user_id)='$user_id'))";

$sup_result = pg_query($connection, $sup_query)
or die("Error in query: $sup_query.
" . pg_last_error($connection));
$sup_row = pg_fetch_row ($sup_result);
$sup_flag = $sup_row[0];
if ($sup_flag == 1) {
echo (&quot;<form name='SubMain' action='benefit_supervsr.org.php' method='post'>&quot;
}

There are two ways to do it.

The first is through the use of a simulated GET-method form submission. In the case of your form, the action attribute would include something like:

<form name='SubMain' action='benefit_supervsr.org.php?thevariable=3' method='post'>

With PHP, this will work even if the form in question is a POST-method form -- PHP will happily accept GET- and POST- method input on the same submission.

Another way is through the use of session variables.

Correction.

There is a third way. Put a hidden field in your form to carry the value over to the next page when the user submits the data.

No luck...

To give a brief process flow:

Page 1-
Users login with a user_id and password. Click SUBMIT. From here, page 2 is loaded.

Page 2-
Has query that checks database to see if user_id is a supervisor. If the user_id is not a supervisor, page 2 executes several queries and displays benefit information about the user_id. If the user_id is a supervisor, I don't want page 2 to display at all. Instead, redirect to page 3. To verify that my parameters are making it to page 2, I echo the $user_id, $password, and $sup_flag, all echo with expected values.

I need pass the user_id over to page 3. I would prefer it not display in the address. This is why I was trying to use POST method.

Still working on it. Thanks for the suggestion.

You're looking for sessions then as sleipnir suggested as another way...

I am going to go with session variables. As this is my third project with PHP, I have not yet had to use session variables. From the brief reading I've done, they sound exactly like what I need.

Thanks for the help.
