[RESOLVED] Passing variables after posting

dcjones

Hi all

Is it possible to pass the content of variables to another page after they have been POSTED into a database.

If I have feilds on page1.php I can pass the data to page2.php by using

<input type="hidden" name="booking_id" value="<?php echo $row_booking['booking_id']; ?>" />

and on page2.php use

<input type="text" readonly name="vat_number" class="coursetext" value="<?php echo $_POST['vat_number']; ?>" size="15">

But if i have on page2.php

<input type="hidden" name="booking_id" value="<?php echo $row_booking['booking_id']; ?>" />

and then on page3.php use

 <td width="35%" class="courseinfo"><?php echo $_POST['first_name']; ?></td>

the data is not displayed. Now this may be because I am ding this completely wrong, or am I.

Any ideas.

It should work fine as long as you have the previous data in hidden inputs inside a form and you're using a submit button to get to the next page.

Hi,

The problem I am having is on page1.php the user inputs thier data and clicks on the "submit" button.

The form action is

<form  action="page2.php" name="form1" method="post" onsubmit="return validate();" />

Page2.php then displays all the data that the user input, and heres the problem, page2.php is to allow the user to check the input and if require click on a back button which goes to page1.php so they can edit.

But when the submit button on page1.php is clicked the data is written to the database.

How can i stop this happening.

Many thank for your help.

Hi all,

Still having problems with passing data from one page to another. I have placed "error_reporting(E_ALL);" at the begining of the page3.php to try and see the error. Found "error_reporting(E_ALL);" on Nogdog's site, thank you Nogdog.

it reports the following:

Notice: Undefined index: booking_id in /homepages/41/d43000764/htdocs/int-int-net2006/page3.php on line 46. I have look at the code and cannot see where this error is. This may notbe waht is causing my problem.

This is what I have so far.

Page1.php passes the data to page2.php with no problem.

Page2.php should pass the data to page3.php but it does not appear.

Where or what am I doing wrong.

Page1.php (picks up "id" from a SQl query)

<input name="course_id" id="course_id" type="text" class="coursetext" value="<?php echo $row_course['id']; ?>" size="20" />
<input type="hidden" name="course_id" value="<?php echo $row_course['id']; ?>" />

Page2.php (user checks if thier input is correct , if yes they click a submit button and continues to page3.pgp. If not correct user clicks on back button and is directed back to page1.php.

<td colspan="3" class="bookingformrowbg"><?php echo $_POST['id']; ?></td>
<input type="hidden" name="id" value="<?php echo $row_course['id']; ?>" />

Page3.php inputs the data into the database, this works fine.

<td colspan="2" class="bookingformrowbg"><?php echo $_POST['id']; ?></td>

Many thansk for your help.

Hi all,

With the help of the error trapping code from Nogdog I have found the errors that the script report so now there are no reported errors.

But still the same data passing problem.

Any ideas.

Many thanks
