Apache Friends Support Forum

I'm using Windows XP SP2 and the latest version of XAMPP. I can't get any PHP "if / else statements" to work. Can somebody please help?

Then your code is wrong...

My code works on my web server. I've created CMS backends and complete PHP sites, I'm not sure how wrong it could be. One of my friends also had this problem with XAMPP for Windows but it works on his Mac with the same code.

I can't even get the simplest code like this to work:

Code: Select all

<?
if ($x == "about") { echo "About"; }
?>

Well, this code is wrong. You are using an undefinded variable in your condition.

With a higher error_reporting level, PHP will report this to you.

With your current (lower) error_reporting level you get no error message, your variable is set to NULL and the condition is allways FALSE --> you have no output from the if-part.

Yeah i know, that's just the code that fails. I define the variable earlier in the document.

I define the variable earlier in the document.

I don't see this in your sample.

Please post a compete example to reproduce your problem.

Code: Select all

<div class="navigation"><a href="?p=home">Home</a>&nbsp;&middot;&nbsp;<a href="?p=about">About</a>&nbsp;&middot;&nbsp;<a href="?p=sitebase">Sitebase</a>&nbsp;&middot;&nbsp;<a href="?p=portfolio">Portfolio</a>&nbsp;&middot;&nbsp;<a href="?p=communicate">Communicate</a></div>
<div class="content">

<?
if (isset($p)) {
$page_path = "pages/$p.php";
if (file_exists($page_path)) { include "$page_path"; }
else { include "pages/404.php"; }
}
else { include "pages/home.php"; }
?>

</div>

There's my code. It has worked fine in my last years of programming, on an actual web server with the most updated software.

Same problem as before... This cannot be the complete code:
- where did you define the variable $p?
- where did you define the variable $page_path?
- the HTML markup is not complete.
