Can you tell me which line of code creates the comment file in fb.php?

I assume this is the line:

$file = fopen("$comments_directory{$image}_com.txt", "a");
fwrite($file, stripslashes("$comment<>$name<>$date<>" . str_rot13($email) . "\n"));

I am running IIS, don't know if that is relevant

I placed
echo("$comments_directory{$image}_com.txt");
just below fwrite and it returned "comments/_com.txt" after submitting a comment

so then I tried
echo("$image");
and it returned nothing after submitting a comment

Could the problem be that $image is not being assigned correctly somehow?

Yes, exactly that is the problem. Now I would advise you to trace back where the $image variable is set.

Sorry, I'm having trouble understanding some things here and I don't know how to debug php because echo isn't working when I insert it in a function. $image appears to be defined here

$image = get("image");

using the get() function

function get($key) {
global $_POST;
if (array_key_exists($key, $_POST)) {
return (ini_get("magic_quotes_gpc")==1) ? stripslashes(trim(htmlspecialchars($_POST[$key]))) : trim(htmlspecialchars($_POST[$key]));
}
return false;
}

What I don't understand is what is the $_POST variable and how do I determine if or where "image" is in this array? if I try to put an echo command in this function the page simply does not load after I post a comment. If I echo("$_POST"); after fwrite, it simply returns "Array". Any ideas? Sorry for all the questions, there's just so little I know about PHP at the moment.

$_POST is a variable returned automatically by a server if you give any parameters to a website (e.g. fb.php?image=12345.jpg)

$_POST is indeed an array, and arrays have to be printed instead of echoed, try "print_r($_POST);". Then you see the existing contents.

By the way, echo always works, also in functions. With regard to your general problem, it seems fb gets no image name from the parameters. What is the URL you use when opening the fb website?

ikue, you are a tireless saint. You have helped me to fix my problem.

I got this returned after posting a comment using print_r($_POST); immediately after get("image");

Array ( [comment] => Test [name] => Test Commenter [email] => test@test.com [url] => http://test.com [doComment] => Submit Comment [cookie] => 1 )

I noticed there was no "Image" in this array and I started looking at the form code in the almanac template and noticed that the post data contained information from each of the fields showing up in $_POST. From there I started comparing templates and noticed that the following field was missing from the almanac template under the form data:
<input type="hidden" name="image" value="<#fbimagename#>" style="display: none;" />

Once I inserted this into the form it worked. The problem was in the almanac_main.php and here is the final code for the form for anyone who would like to cut and paste later.

<form method="post" action="<#fbcommentslink#>">
<div class="comform">
<textarea style="width: px;" cols="40" rows="4" name="comment"><#fbcomval#></textarea>

<input style="width: px;" name="name" size="44" maxlength="20" value="<#fbnameval#>" /> Name

<input style="width: px;" name="email" size="44" maxlength="40" value="<#fbemailval#>" /> Email

<input style="width: px;" name="url" size="44" maxlength="100" value="<#fburlval#>" /> URL

<input type="hidden" name="image" value="<#fbimagename#>" style="display: none;" />
<input id="submit" type="submit" value="Submit" name="doComment" /> <input id="check" type="checkbox" name="cookie" value="1" <#fbchecked#> /> Remember me</span>
</div>
</form>

I am really glad I could help you, although I also have to congratulate you to your detective sense! ;) Really a stupid hidden little bug with huge implications...

Take care!

Thank you both for pointing this out. But in my newest version of alamanac which is for the lastest official beta 3.16 this line of code is already integrated, but comments only work on the newest image, that is:

http://www.jowra.de/fb316/fb.php/

At the image "big one" comments work, but at all other images, there simply is happening nothing. No _com.txt or so, simply nothing.

If you need the new package for testing you can find it here:

http://www.jowra.de/downloads/almanac3.16.zip

Any ideas?

Then there still seems to be a problem that fb just does not handle correctly the parameters (the image filename). First, do one thing: Compare the template codes of yours and the relaxation theme (which works fine on my blog), and if there are not any problematic differences do the same with the final output of these websites.

If that still doesnt work, we have to start some debugging internally in folderblog...
