Engines

Throughout this extension you will see and interact with the word "engine". This describes the library/package used to render the images. Examples of engines are Fancybox and Swiper. There is also an Ajax and Basic engine included which, by default, adds no extra CSS or JavaScript.

Configuration

Media Gallery comes bundled with several libraries included, which can all be configured via the $GLOBALS array to alter their behaviour. You also have the option of adding your own media gallery engine if desired.

Remove assets of an existing engine

If an existing or added engine includes assets which you, yourself, are bundling in your site package or FE assets, you can remove assets in various ways.

You can add the following to your ext_localconf.php:

• $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['media_gallery']['engines']['fancybox']['excludeAllAssets'] = true - This removes all assets added by the engine
• $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['media_gallery']['engines']['fancybox']['excludeAssets'] = true - This removes stylesheet and javascript assets added to the document
• $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['media_gallery']['engines']['fancybox']['excludeInlineAssets'] = true - This removes any inline assets

Alternatively, you can unset() a specific item - e.g.:

Remove an engine

It might be that you don't want some (or any) of the default engines to be available. In which case, you can unset the entire engine.

For example, to remove the base & carousel engines:

Add an engine

Engines are set via $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['media_gallery']['engines'] and appended to the array.

The key should be a simple/slugified version of the engine/plugin. This allows unsetting and overriding should that be required.

The array can have several keys to add assets & define settings - all of them optional. See below for an explanation of the assets.

Adding a new engine

Assets

The 4 asset keys (styleSheet, javaScript, inlineStyleSheet, inlineJavaScript) allow you to load assets when the particular engine is loaded. Each one can take a string or a (multi-dimensional) array and is passed to the TYPO3 AssetCollector (docs).

Most of the time, the string will be enough, however there may be times where you need to set the priority or add data attributes.

This applies to all 4 assets, but as an example, the CSS can be formatted in 3 different ways:

As a string

As an array

As a multidimensional array

This allows you to set attributes and options as you would if using the AssetCollector directly

Templates

If you wish to override any partials, add the following to your constants.typoscript.

Alternatively, you can add them directly to the setup.typoscript

Note: The custom <gallery:assets engine="{engine}" /> view helper is how the assets are injected into the template - ensure your template contains this if overriding the Gallery.html

Upgrading

When upgrading from v3 (our internal, private package) to v4, please do the following:

• Install the new gallery
• Run typo3cms upgrade:prepare and typo3cms upgrade:run mediagallery_galleryUpgradeWizard
• Include the TypoScript, either via a static include or including it in your application:
  • Constants: @import 'EXT:media_gallery/Configuration/TypoScript/constants'
  • Setup: @import 'EXT:media_gallery/Configuration/TypoScript/setup'
• Add template overrides to match the existing gallery
• You may need to unset some assets if libraries are already loaded (e.g. Fancybox)
• Look at unsetting any engines not used
• Deploy (if required, run conversion script on live after backing up the database)
• Enable the following for Role - Editor
  • Tables (listing): File collection
  • Tables (modify): File collection
  • Page Content: File collections

• Create a folder called "File Collections" inside Resources
  • Move any File Collections to that PID (UPDATE sys_file_collection SET pid = '')
