Craft Asset Usage plugin

Adds a column to the assets overview to see which assets are used or unused. For Craft 5.

The "Usage" field shows all relations and the "Current Usage" field shows relations excluding revisions and deleted elements.

Setup

• Go to admin/assets
• Click the "sprocket" icon
• Check the "Usage" or "Current Usage" column
• Save
• The assets table should now show a "Usage" or "Current Usage" column indicating usage

Settings

The setting values can be overridden from a PHP file within your project's config/ folder, named assetusage.php.

The file just needs to return an array with the overridden values:

<?php

return [
    'includeRevisions' => false,
    'renderUsedByInAssetDetail' => true,
    'includeContentSearch' => true,
];

Setting	Default	Description
includeRevisions	false	Whether to include draft and revision elements in the usage count
renderUsedByInAssetDetail	true	Whether to show the "Used by" list in the asset editor panel
includeContentSearch	true	Whether to scan elements_sites.content for asset references stored outside of standard Craft relations. Can be disabled for a performance improvement on large installs

Support

Does NOT support (assets not connected through relations table)

• Redactor
• ether/seo

Commandline usage
