COPS : Calibre OPDS PHP Server

@mariosipad

Thanks, but I figured it out in the end. Just needed to create a password file with htpasswd and then point to it in the AuthUserFile line of the .htaccess file.

I would second bkwrmgrl's suggestion of better documentation for COPS.

Hi all,

I'll also second the suggestion of a better documentation but to be completely honest I've very little time to spend on it. I also personally think that a good documentation is a documentation written by users and validated by developers.

On the other hand, I'd be happy to read / validate any addition to COPS's wiki (https://github.com/seblucas/cops).

Be prepared for a new version of COPS in the next 2 weeks !

Hi vlad59

In my experience the problem with the documentation of COPS is that because COPS can be installed on Windows, Linux, OSX, NAS-es, etc. and works with several different web servers (apache, nginx, etc.) every installation, especially when done for the first time, is almost unique. However once installed on one system it's quite easy to setup other systems.

It's sometimes easier (and more fun) to answer user questions one at a time than to provide a comprehensive all incorporating tutorial (all really good documentation takes a lot of time and effort).

Maybe it's an idea to expand the wiki with some beginners topics?

Hey vlad59,

First up, congratulations on COPS, it's excellent. Completely understand you don't have time yourself to write detailed documentation, and totally agree it would be better written by the many users, especially since (as mariosipad points out) there are so many possible implementations.

I'd be up for contributing, but since the installation for me was really simple, the only thing I could contribute is how to set up password protection (on a Linux-based web server, in case it's not the same in every case), since I had to do a bit of digging to find out about htpasswd. But I imagine there are far more qualified people than me who could do it much better.

Hi,

I'm not sure if I'm posting this in the right place but I'm having trouble getting COPS to work on my server.

checkconfig.php displays fine and says everything is ok but when I try to display the default index.php I get the following error:

Parse error: syntax error, unexpected T_FUNCTION, expecting ')' in /i-data/f6f9a6d4/library/book.php on line 142

I'm not a php expert but the code in there looks fine... Is there anything I can change to get it working?

I hope you can help.

Server: NSA325 running FFP 0.7 ARM.
PHP: 5.2.8
MySQL: 5.1.30

Hi,

The problem lies with your PHP version you'll have to use PHP >= 5.3

You can't use PHP 5.2.8.

Hey vlad59,

Thanks for getting back to me so quickly. I thought that might be the case... I'll try to find a way of upgrading it.

I use the excellent COPS on my iPad Air with Marvin.
I have a strange behavior though... since a bit, the local OPDS or WEB connection to COPS from my iPad is not working, while if I access the same server via my DDNS account, it works...

So locally, not working, remotely working...

what can it be ??????

Thanks!

M

Are you sure your iPad is (with WifI) connected to the same network (LAN) your COPS server is in, and not connected to the network of your neighbour (or public ISP network)?

Both COPS installations I am running 0.9.0-1 and 1.0 RC1 (for testing and for working out how to use passwords) work really well.
I prefer this approach as it ensures that any changes are immediately available.
BTW, really appreciate the effort vlad and other coders put into this project.
I follow this thread and used it extensively to help me work out pitfalls not to fall into when starting to use my new NAS for serving my ebooks.

I have a DS414 with the latest version of DSM 5 but the cops do not work. It cannot find the database metadata.db. Can someone tell what he did and worked.
Thanks

@ekekakos

Please post your "config_local.php" and a screenshot of http://<IP-Synology>/cops/checkconfig.php zo that we can determine what is wrong.

With a little luck the answer posted here will help.

I don't think this has been mentioned before, but half-star ratings do not display correctly. It rounds the ".5" value up and then you get a rating out of six stars instead of five i.e. ★★★★☆☆

I'm using an older version of COPS but the bug appears to be in the latest cops-1.0.0RC1 also. The culprit seems to be the getRating() function around line 250 of book.php

Find this...

PHP Code:

public function getRating () {
    if (is_null ($this->rating) || $this->rating == 0) {
        return "";
    }
    $retour = "";
    for ($i = 0; $i < $this->rating / 2; $i++) {
        $retour .= "★";
    }
    for ($i = 0; $i < 5 - $this->rating / 2; $i++) {
        $retour .= "☆";
    }
    return $retour;
} 


I added my own variable that rounds all ratings down...

PHP Code:

public function getRating () {
    $myrating = floor(($this->rating)/2);
    
    if (is_null ($myrating) || $myrating == 0) {
        return "";
    }
    $retour = "";
    for ($i = 0; $i < $myrating; $i++) {
        $retour .= "★";
    }
    for ($i = 0; $i < 5 - $myrating; $i++) {
        $retour .= "☆";
    }
    return $retour;
} 


There is probably some clever PHP way for dealing with floats that would give you a half-star rating, but I'm not a programmer. I'm not even sure that my hack is a good fix.

I just wanted a five star rating and I don't mind if my ratings get rounded down (they could just as easily be rounded up instead) so this works for me.

@micster

I didn't know the ratings could be a float. Within Calibre you can only set it to value from 0 stars to 5 stars or did I miss a setting ?

Once I find out how to have a correct testcase I'll fix it soon.

My books seem to be rated from 0-10. And yes, they start off as whole numbers and not floats. But then if a book has a rating of five and then it gets divided by 2 in the function getRating () we are left with the float 2.5 which causes a problem.
