For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Passing PHP Variables in a URL

Posted by horwem (horwem), 8 June 2004
Hi

Having trouble pasing variables using a url.

The code is

<a href="temp.php?bg=hello">test</a>

and the temp.php code

<?

echo $_GET['bg'];
?>

The code runs but nother is shown on the screen, I am running php using IIS.

Can anybody help

Thanks

Your code looks fine .. but are you actually sure you're running PHP?  It could be that IIS is just serving out the page as HTML.   Try viewing the source on your browser and if you see the PHP, then you'll know that's the problem.

It could also be that your server is set up to need <?php rather than just <? to start your PHP program section.

Got it to work by change the temp.php code to

echo $bg;

Thanks for all the help

Glad it's fixed.

For anyone else who has a similar problem and wonders about the solution, the $_GET array was introduced at PHP 4.1 as an additional and safer way to get information from forms, and as from 4.2 $_GET (and other similar arrays) became the only default way to get information from forms.

Prior to PHP 4.1, form information appeared in programs in regular variables, and this is what has worked for horwem.  It would seem, then that horwen has a relatively old version of PHP.
