Carrying $_POST vars to next page

  • June 23, 2008

I have a form processing page, which uses the $_POST variables to insert a record - simple.

What I am trying to do is to use these same $_POST variables in the next page (after submit) to create an e-mail which will then be used to verify that the e-mail address is true.

I am fairly new at this and I'm not sure how to do this....

I thought by using the following, I could re-capture the variables and use them on the next page, but obviously not.

<?php
$username=$_POST['username'];
$postgroupcode=$_POST['groupcode'];
$email=$_POST['email'];
$title=$_POST['title'];
$firstname=$_POST['firstname'];
$lastname=$_POST['lastname'];
?>

Does this mean I have to put the mail function in the same page as the record insert function?

Use a session variable.

Put this at the beginning of the page:

session_start();

Then capture the $_POST variable and assign it to a $_SESSION variable
like this:

if (isset($_POST['variableName'])) {
$_SESSION['variableName'] = $_POST['variableName'];
}

If your server uses magic quotes (run phpinfo() and see if
magic_quotes_gpc is "On"), change the code above to this:

if (isset($_POST['variableName'])) {
$_SESSION['variableName'] = stripslashes($_POST['variableName']);
}

You can now access $_SESSION['variableName'] in any page that begins
with session_start().

David - my apologies, I will lift the session start to the start! (this evening).

Micha - If I'm using a simple redirect in the insert function, do I need any additional buttons other then the submit??

With David's solution, I only need 2 pages. On the 2nd page, the user will be encouraged to close the window and follow an <aref> URL from the mail which is sent.

As Murray mentioned to start with, it would have been easier to put the mail function in the first post page, but I was getting header issues that I couldn't resolve. (Headers already sent blah de blah)

Thanks for your help guys. This is probably the most critical part of the website and it needs to be right!

That's the worst way for doing it. You're wasting a lot of bandwidth
with these ping-pong data transfers and would have to revalidate the
data over and over again, because users can always manipulate it.

Additionally it would always require a button instead of a simple link
to navigate between the pages.

Sessions are the correct and most efficient way for this, because it's
exactly what sessions are made for.

Perfect!

I can use both these techniques. Both answers are ideal.

Murray - I will put the mail function on the post page as you suggested.

David - thanks for this too - I can now pass the variable to the next page where it will show the user what is being sent and why. (My server does use magic quotes)

Thanks Guys.

OK - don't know what I'm doing wrong...

I've put Davids script in the form processing page and followed the advice for the 2nd page but it isn't carrying the variable.

I've tried the magic quotes and non magic quotes solutions.

Post from page A to page B. Page B loads hidden form fields with the
information posted from Page A. To navigate away from Page B, you click a
button which submits the hidden fields to Page C. That's typically how it's
done.

Alternately, you could post to Page B, and include those posted data in URL
variables, or cookies, or Session variables when you link to Page C.

Like that.

This is a good question. Even though his objective might be solved in other ways. It would be great to get an answer to his original inquiry.

I am also interested in using a posted variable from a form on other pages of the site.

The form posts to one page (the receipt page). You can use the form variables easily on that page (the receipt page) by creating a form variable and dragging it to where you want it on the page.

BUT, how can you use this information on other pages in the site? What type of "variable" would you create and how?

Why go to another page? Just place the email code on the form processing
page.
