Session not passing data!

rocky48 · December 13, 2022

I have screwed up my code, was working but copied wrong file and was running incorrect file.

Basically it appears to work and runs without error, but it should print the verse I have chosen but prints 'You have selected an invalid Verse. Please try again' which is an error message in the file Prnpdf.php.

My conclusion is therefore that the session is not passing the data from the previous file, varinput.pdf, but the file that I messed up as the one called varinput.php and all the other files are the original files, so I can't see why it is not working! Is there something wrong with the session in that file?

The sequence of the files running is as follows:

vinput.php -> vquery.php -> varinput.php -> prnpdf.php -> fpdf.php

vinput.php

session_start();

Needs to be called before any HTML is outputted.

Add

<?php session_start(); ?>

To the top of your pages above <!DOCTYPE html> and it'll work.

php variables are case sensitive. $_SESSION['test'] is not the same as $_SESSION['Test']. you would have been getting a php error to alert you to the problem. do you have php's error_reporting set to E_ALL and display_errors set to ON, preferably in the php.ini on your development system, so that php will help you by reporting and displaying all the errors it detects? you will save a ton of time.

most of the form markup is broken, and it's doubtful that you even have some of the shown input data. you need to trim, then validate all inputs before using them. if a 'required' input is not valid, that's an error and you should setup and display a user message rather then blindly attempting to use non-existent data. you should validate the resulting web pages at validator.w3.org to help find the mistakes in the markup.

the user errors you do have are also not preventing the code needing the inputs from running, likely producing php errors and no result. $display_block is being overwritten by later code, so any user errors you may have setup are being lost. you need to store user/validation errors in an array, using the field name as the array index, then only use the input data if the array holding the errors is empty.

DanRz - I had forgotten about that thanks!

I have now added Error reporting and corrected the capitalisation issue with the session name.

It now reports a warning on the line where I corrected the session name:

Warning: Undefined array key "test" in /homepages/39/d922140697/htdocs/1066cardcraft/Prnpdf.php on line 42
The fatal error is on this line:
Fatal error: Uncaught Exception: FPDF error: Some data has already been output, can't send PDF file (output started at /homepages/39/d922140697/htdocs/1066cardcraft/Prnpdf.php:42) in /homepages/39/d922140697/htdocs/1066cardcraft/fpdf.php:271 Stack trace: #0 /homepages/39/d922140697/htdocs/1066cardcraft/fpdf.php(1049): FPDF->Error('Some data has a...') #1 /homepages/39/d922140697/htdocs/1066cardcraft/fpdf.php(1012): FPDF->_checkoutput() #2 /homepages/39/d922140697/htdocs/1066cardcraft/Prnpdf.php(145): FPDF->Output('D', 'verse.pdf') #3 {main} thrown in /homepages/39/d922140697/htdocs/1066cardcraft/fpdf.php on line 271

What is being output?

What baffles me is that these files were working before I miss copied the wrong Vinput file ( I had one file vinput.php and the other vinput1.php and over wrote the second file with the same code as the first file. So the only one that has been changed is the file varinput.php ( I renamed it to stop the confusion).

I can't even think about some of the suggestions Mac_gyver made until I resolve why this is not working. All of the choices are in option lists so I can't see that over complicating the code with input checks would achieve anything!

What is being output is the warning message. Fix that and then see what happens

rocky48 · December 14, 2022

Fix What? I know that it is not passing the data via the session, but I can't see why?
This code has worked for me since 2012 and it only seems to have gone wrong since I messed up a file.

I can't see why that any data has already been output. Nothing should be output until you submit on the varinput.php page.

Please can anyone spot why this is happening, because I am stumped!

ginerjm · December 14, 2022

Fix What you ask. Correct that error message as it tells you. You are referencing an element named 'test' in an array somewhere. It says line 271 so find that line and make a change and that will stop that message. Then see how far your code makes it before it shows us any other error.

It's called debugging. Try this out too. Find the spot in your code where you think that some SESSION values should be getting used. Add an echo statement or two to display the values you think are being missed and see what comes out. At least you will know that the code is being hit.
