Error

[dinosaw]

Hello,

I don't seem to be able to get this working right. I have the irssi logs configured within irssi as you suggested, and verified that they show up in the irssi conf file.

I also made sure I have the symlink in the correct location.

However when I try and browse the site, everything loads except the logs. When I check the Apache logs, I see this:

[Thu Oct 25 19:20:35 2018] [error] PHP Warning:  Invalid argument supplied for foreach() in /home/admin/web/public_html/index.php on line 19

When looking at line 19 on index.php, it's the foreach line in the below snippet:

<?php
foreach(glob('logs/*', GLOB_ONLYDIR) as $dir) {
        $dir = str_replace('logs/', '', $dir);
        echo "<li><a data-target=\"#\" data-toggle=\"pill\" href=\"#\" onclick=\"changeChannel('$dir')\">$dir</a></li>";
}
?>

Any ideas?

Looks like your logs/ directory is empty or script does not have access to read from it. The script itself lacks check if glob() returns any iterable object.
Are you sure the logs are actually saved on the disk in specified folder?

Try adding this if protecting the foreach statement:
$files = glob('logs/*', GLOB_ONLYDIR);
if (is_array($files) && count($files) > 0) {
foreach($files as dir) {
...
}
}

Regarding the logs/ directory, and the permissions and its contents, it should be set up correctly. It's owned by the user it needs to be (in my case, admin) and permissions are correct. This is the ouput from the public HTML directory:

$ grep "foreach" index.php
foreach(glob('logs/*', GLOB_ONLYDIR) as $dir) {

As far as adding that code snippet you provided - where exactly would I put that?

Thanks!
