bookstack autosort tagged books

readme.md

This is a hack to BookStack, using the theme system, to enable auto-sorting of book chapters and pages upon page or chapter create/update. It sorts by name, ascending, with chapters first. By default it will run for any book with an Autosort tag assigned.

Setup

This uses the logical theme system.

1. Within the BookStack install folder, you should have a themes folder.
2. Create a themes/custom/functions.php file with the contents of the functions.php file example below.
3. Customize the tag name, if desired, by teaking the string at around line 45. Set this to empty to run for all books.
4. Add APP_THEME=custom to your .env file.

Note

This can slow down page & chapter create & update system events. These customizations are not officially supported any may break upon, or conflict with, future updates. Quickly tested on BookStack v22.11.1.

    foreach ($chapters as $index => $chapter) {
        $chapter->priority = $index;
        $chapter->save();
