Error 500 when iframe calls PHP script - Fixable?

[Lawrence]

I have a blog that doesn't allow PHP in some pages.

In these pages, I want to include the latest image from my gallery. I can work around the PHP limitation by using the blog's INCLUDE function to call another HTML file.

This HTML file contains a single line of text, that creates an IFRAME and uses a PHP file as the source for the iframe.

The code for both is below:

IFRAME.HTM

<iframe name="random" src="/directories/iframe.php" width="170" height="170" scrolling="no" frameborder="0"> </iframe>

IFRAME.PHP

<?php readfile('http://domain.com/url/main.php?g2_view=imageblock.External&g2_blocks=recentImage&g2_show=title'); ?>


All I get is an Error 500. If I open the iframe directly I get an error 500, but if I open the PHP file I get the right result: the latest image from my gallery.

For some reason Abyss chokes when asked to call a PHP file from an iframe. Or am I doing something wrong? Ideas are appreciated.

Lawrence,

For Abyss Web Server it makes no difference if the file is called from an IFRAME or not. So we suggest to check the exact cause reported for error 500 (see the cgi.log file).

That's the kind of authoritative answer I crave, thanks. Here's a paste from the cgi log (which I didn't even know existed, heh):

CGI: [c:\appz\php\php.exe ] URI: /directories/iframe.php Broken pipe

For clarification, here are the more-accurate directories in question:

Both the iframe.php and iframe.htm files are in root/dir1/ and the gallery script is in root/gallery/.

iframe.htm finds the PHP script no problem, but the PHP script is apparently confused.

No amount of tweaking the readfile parameters will cure the problem - I've tried full URLS (http://etc/gallery/) and relative URLS (/gallery/) and filesystem addresses (e:\web\gallery\) to no avail.

Lawrence,

Could you please turn on the following error displaying parameters in php.ini:

[Lawrence]

Both of those settings were already enabled on my system. I don't use FastCGI. No errors are generated by PHP, unless I change the script so that it cannot locate the file.

I don't know which script source code you mean. If you're referring to the iframe.php, the entire script is listed above (and again below for convenience). If you mean the gallery script, I'm using gallery2.

<?php readfile('http://domain.com/url/main.php?g2_view=imageblock.External&g2_blocks=recentImage&g2_show=title'); ?>

The only thing showing up in cgi.log is the 'broken pipe' error.

I should clarify the first post: Neither iframe.php or iframe.htm will produce the desired results.

Lawrence,

Could you please send to support@aprelium.com your abyss.conf and php.ini files? Please do not forget to add a reference to this post and to give us the full URL of the PHP script which fails.

By the way, when you browse the IFRAME, how much time is needed to have Error 500 displayed? Is it instantaneous or not?

I've sent the files you've requested.

The iframe.php file fails in what appears to be exactly four seconds.

Thanks to the guys at Aprelium, the problem's been solved. Or rather, a new solution was found:
