PHP4 to PHP5, but what is PHP4 and PHP5?

dendjos · January 20, 2009

Hi, I have a problem. My hosting has updated from php4 to php5 and I have a function that refuses to work. I'm not an expert in php and it's very important to have this up and running again. Can anybody help me? This is the current php:

<?php

$sql3=mysql_query("SELECT * from kalender where Datum>'2008-06-06' order by Datum desc");

if (!$sql3)

{

echo("Er deed zich een probleem voor, contacteer de webmaster");

exit;

}

else

{

while ($row=mysql_fetch_array($sql3))

{

$datum=$row["Datum"];

$huidige=date("Y-m-d");

$Jaar = substr($datum, 0, 4);

$Maand = substr($datum, 5, 2);

$Dag = substr($datum, 8, 2);

$datum="$Dag-$Maand-$Jaar";

$titel=$row["Naam"];

$titel=strtoupper($titel);

$id=$row["IDkalender"];

$locatie=$row["Locatie"];

$start=$row["Startuur"];

printf("<tr valign='top'>");

printf("<td>$datum</td>");

printf("<td><div align='left'>$start</div></td>");

printf("<td>$titel</td>");

printf("<td>$locatie</td>");

echo("<td><a href='kalender.php?IDkalender=$id' onmouseout=\"MM_swapImgRestore()\" onmouseover=\"MM_swapImage('LinkTeksten14421','','images/gifs/kleinpijltjeb.gif',1)\"><img src='images/gifs/kleinpijltje.gif' name='LinkTeksten14421' border='0' align='absmiddle'/></a> Meer info </td>");

printf("</tr>");

}}

?>

There is nothing in that code that is specific to php5. Are you getting any errors? I don't see any db connection being made.

My hosting has updated from php4 to php5 and I have a function that refuses to work

ahhh dutch. What function is it that doesnt work? and what are the errors?

dendjos · January 20, 2009

well, it's a calendar function that does not generate an individual page for each activity anymore.

http://www.lvsvleuven.be/kalender.php If you click on "Meer info" you should get a page with more info for this event from our database... The problem started the same moment as the update from php4 to php5... So I think there must be something wrong there...

We need to see the relevent code, a link doesn't help us.

What is the error you recieve? can you turn on errors on the server?

dendjos · January 20, 2009

Well, instead of generating a page for the event, it just reloads the calendar page...

The problem appears to be that you have registrer globals enabled. A quick insecure fix is to simply add....

extract($_POST);

at the top of your script.

A better (more secure method) would be to find all these magically defined variables and reference them from the $_POST array. eg; $Submit becomes $_POST['Submit'].

RichardRotterdam · January 20, 2009

as trope said its registered globals.

this is what i found you have the following code

if (isset($IDkalender))

{

    $sql4=mysql_query("SELECT * from kalender where IDkalender=$IDkalender");

but you never asigned the value.

a better fix would be to add the following

$IDkalender=(int)$_GET['IDkalender'];

dendjos · January 20, 2009

Thanks a lot 4 the help you all, I have been experimenting but I don't know where to change what. Could you please tell me what to replace where by what?

Thanks!

Every program variable $some_variable_name in your code must have a statement that assigns a value to it.

Register_globals "magically" did this from POST/GET/COOKIE/SESSION data in a lazy-way attempt to make programming easier. Unfortunately, register_globals also "magically" allowed hackers to set session/program variables, so a lot of sites were taken over because a hacker could become logged in as an administrator to scripts where he knew or could guess what the variable names were that controlled the log in state.

You can turn on full php error reporting and the variables that are no longer being "magically" populated will generate "undefined" error messages. However, to fix the code you will need to determine where each variable is coming from - POST/GET/COOKIE/SESSION. The functions session_register(), session_is_registered(), and session_unregister() also no longer work and any code using them needs to be fixed to use $_SESSION variables.

The sad part of this is that register_globals were turned off in php4.2 in the year 2002 and no new code should have been written after that point in time that used register_globals and any code that existed at that time should have been updated long ago.

well said wish everyone would read this.

dendjos · January 20, 2009

I tried the function of PFMaBiSmAd in his signature...

It says that the error is somewhere in here:

while (($row=mysql_fetch_array($sql2))&& ($stop!="ja"))

I'm really new to php, i just have to maintain a website with php-modules and I usually only have to fix a link or a picture... But this is a bit over my head...

revraz · January 20, 2009

In that line, you are grabbing the mysql rows from the database and putting them into the $row array, while also checking the $stop variable to make sure it does not equal to "ja".

How do i fix that? :-[

If you seriously don't know what you are doing you might consider hiring someone. This script is pretty well riddled with errors and fixing one after the other by asking questions here is going to be a long slow process.

dendjos · January 20, 2009

Well, we are a student group, we really don't have a budget for hiring someone...

revraz · January 20, 2009

How is it broken?

Without knowing your intentions, in syntax, there is nothing wrong with it.

PHP4 to PHP5, but what is PHP4 and PHP5?
