You have upgraded Calibre to version 5.x?

If so, then your php-sqlite3 version is no longer compatible with Calibre 5.

Not a COPS “error” but a PHP-sqlite error.

Solution:
- update PHP to PHP 5.6 ot 7.x (with at least php-sqlite3 version 3.9)
- use Calibre version 4

After using calibre-server with mixed success for a few years I finally discovered COPS this week. I want to use it on a Rapberry Pi running Ubuntu 20.04, nginx and php7.4 and after a couple of false starts it's running but with one issue to solve. I believe that the "folder" icon should allow the user to open the book for viewing - is this correct? Should it work in a web browser as well as an OPDS viewer? Clicking on the Download icon works fine on Chrome and Firefox, but clicking on the View icon downloads a file named fetch.php but which is much larger than the COPS fetch.php file and is not a text file. Any ideas on how to fix this?

In firefox to "view" an ePub you need an "add-on" like EPUBreader. It does not work without.

This "viewer" feature of cops never properly and consistently worked for me.

Thanks mariosipad. I was hoping that epubreader.php was an internal reader which would be called by the main program. I just want to share books with my family and don't actually need a viewer, so I would be happy to modify the program to edit out the relevant bits if somebody could give me a nudge in the right direction!

[mariosipad]

What do you want to “edit out” exactly?

Cops has an internal reader.
In the detail pop-up of a book click on the “eye” icon.

I'll get back to your first question later, but your second comment puzzles me! I've tried browsing my library with both Firefox and Chrome, and on neither do I see an "eye" icon. I've attached a screen shot of what I can see on the popup detail of a book. The icon which I assume should open a viewer looks like an open folder - have I got that right?

EDITED: On further inspection I think that trying to understand and edit the COPS php files is beyond my feeble programming skills. I'm just using COPS to share ebooks with my family so I'll make sure they don't click the button which is causing a problem on my installation. Thanks for the response anyway!

1 - the "eye" icon
You will only see the "eye" icon (see picture1) if it's an EPUB-file, not if it's a MOBI-file.

2 - "edit out"
Well it turns out that what you wanted to "edit out" I have "edited out" for years! (Great minds think alike ) And it's quite simple to do.

- in your cops directory go to ./cops/templates/default/
- in a text editor (not word) open main.html
- delete (or comment) line 31.
- the commented line now looks like:

 <!-- <a href="{{=data.viewUrl}}" {{=it.c.config.kindleHack}}><i class="fas fa-folder-open fa-lg"></i></a> -->

- save file

- in a text editor (not word) open bookdetail.html
- delete (or comment) line 12.
- the commented line now looks like:

        <!-- <a title="Open // {{=data.format}}" href="{{=data.viewUrl}}" {{=it.c.config.kindleHack}}><i class="fas fa-folder-open fa-lg"></i></a> -->

- save file

That should do it. If not, let me know!

Are there any more templates for COPS out there? I've checked out the builtin bootstrap template, but am looking for more options.

Or any guides/info on making new templates?

[mariosipad]

Not that I know.

To make new templates you could look at the source code and adapt it to your needs.
I’m not aware of any howto.

Sorry for the delayed response mariosipad. That WAS simple, and it did exactly what I wanted. I was looking in completely the wrong place to make the changes and wouldn't have found this without your help.

Many thanks, you're a star!

I'm not the biggest fan of the COPS bootstrap theme, but I love how COPS functions. So I updated the bootstrap theme more to my liking. Here's a couple screenshots

This is probably a noob question, but how do I install this? Do I re-install cops completely using the link above, or just copy parts of this to my existing installation?

Thanks

[Freakeao]

Native (non-docker install):
copy templates/bootstrap2 into your current install
and also copy util.js from my repo over the util.js in your current install.

update config_local.php to include

$config['cops_template'] = 'bootstrap2';

I've submitted a pull request to support more templates, but until that is merged you will have to edit config_local.php to select this template.

For a docker install (which is how i have COPS installed) I mounted a couple extra volumes pointed at my development directories.

volumes:
- /opt/appdata/cops:/config
- /mnt/storage/media/Books:/books
#extra dirs to use bootstrap2
- /mnt/storage/github/cops/util.js:/usr/share/webapps/cops/util.js
- /mnt/storage/github/cops/templates:/usr/share/webapps/cops/templates

Thanks very much! I copied the directory and can see your changes.

Very nice!
