Set php variable from text box value

Hello Experts;

I am setting a variable when page 1 is opened for transfer and display on page 2:

// Set session variables
$_SESSION['bbc2'] = "Two door cabinet";
No problem...

On the same page I have a text box for entering quantity which I want to transfer and display on page 2:

<form action = "" method = "POST">
Quantity: &nbsp; <input type="submit" name="submit" value="1" style="width:50px">
if(isset($_POST['submit'])) $_SESSION['qbbc2']="value";

 I can't figure out how to retrieve the value from the text box and set the second vaiable $_SESSION['qbbc2'] to equal the text box value for tranfer and display on page 2.

Help would be greatly appreciated.

Thank you,

This would be your form on page 1. You need to add a form field to enter the data.
<form action = "page2.php" method = "POST">
Quantity: &nbsp; <input type="text" name="qty" value="0">
<input type="submit" name="submit" value="1" style="width:50px">

Open in new window

Then on page2.php
if(isset($_POST['qty'])) $_SESSION['qbbc2']=$_POST['qty'];

Open in new window

This is a bit simplistic and you will want to verify the data which in this case is to make sure qty is an integer and perhaps within a certain range say 0 to 100?

Figured it out...

<form action="" method="POST">
<input type="text" name="qty">
<input type="submit" name="submit">
if (isset($_POST['submit']))
$quantity = $_POST['qty'];
$_SESSION['qbbc2']= $quantity; sets the variable for transfer and display on page 2.

Hi Scott;

Thank you I didn't see your post prior to my comment, your code is quite similar to what I used.

Yes, we posted at the same time.

Just remember to add some type of validation before doing anything with that qty number or any posted data.
