Identify & fix Duplicate IDs in Statamic 3.

Duplicate ID Identifier & Fixer for Statamic 3

Instructions:

• Copy the contents of this gist's console.php into routes/console.php
• Run php artisan identify-duplicates

At the start of the script, it will ask you if you want to replace any identied duplicate IDs. If you choose to do so, new Stache IDs will be generated and the Laravel cache will be cleared.

console.php

<?php // copy everything after this line

Artisan::command('identify-duplicates', function () {
    $duplicates = [];
    $shouldFixDuplicates = $this->confirm('Should Duplicate IDs be replaced with fresh IDs?');

    $items = collect(\Illuminate\Support\Facades\File::allFiles(__DIR__.'/../content'))
        ->filter(function ($file) {
            return $file->isFile();
        })
        ->map(function (SplFileInfo $file) {
            $data = \Statamic\Facades\YAML::parse(file_get_contents($file->getRealPath()));

            return [
                'path' => $file->getRealPath(),
                'stache_id' => isset($data['id']) ? $data['id'] : null,
            ];
        })
        ->reject(function ($item) {
            return is_null($item['stache_id']);
        });

    $items->each(function ($item) use (&$duplicates, $items) {
        $itemsWithCurrentId = $items->where('stache_id', $item['stache_id']);

        if ($itemsWithCurrentId->count() > 1) {

                $contents = str_replace($id, \Statamic\Facades\Stache::generateId(), $contents);
                file_put_contents($item, $contents);
            }
        }

        $this->line('');
    }

    if ($shouldFixDuplicates) {

It probably means you have some invalid characters in one of your YAML files. This script is no longer relevant since you can now resolve duplicate IDs in the Control Panel.
