Installation / Integration

First install the extension and activate it in the Extension Manager.

Vimeo app

• Create a new vimeo app: https://developer.vimeo.com/apps/new
• Answer the question Will people besides you be able to access your app? with: No. The only Vimeo accounts that will have access to the app are my own.
• Go to your vimeo app on https://developer.vimeo.com/apps and copy your client identifier & client secret.

TypoScript integration

• Include the TypoScript in Configuration/TypoScript/setup.typoscript and constants.typoscript in your theme.
• Add your Vimeo client identifier & client secret (and optionally your personal access token):

plugin.tx_sgvimeo {
	settings {
		# cat=plugin.tx_sgvimeo/file; type=string; label=Vimeo client identifier
		clientId = <your-client-id>
		# cat=plugin.tx_sgvimeo/file; type=string; label=Vimeo client secret
		clientSecret = <your-client-secret>
		# cat=plugin.tx_sgvimeo/file; type=string; label=Vimeo Personal access token
		personalAccessToken =
	}
}

Private videos

If you have a video which is not available to the public, but you want to show it on your website, you need an authenticated personal access token. You can find a guide, on how to generate such a token here: https://vimeo.zendesk.com/hc/en-us/articles/360042445032-How-do-I-generate-a-personal-access-token-

The following requirements have to be met, for the private video to show up:

• the video has to be hosted on the same vimeo account, that was used to configure the clientSecret & clientId (vimeo app)
• a personal access token with access scope "private" has to be configured in the typoscript settings ( personalAccessToken)

Working with Rate Limits

As with almost every API, there is a usage limit, which depends on the vimeo user membership of the user, that makes the API requests (the owner of the vimeo app).

sg_vimeo uses the following endpoints:

• Video - api.vimeo.com/videos/{video_id}
• Channel Videos - api.vimeo.com/channels/{channel_id}/videos

sg_vimeo uses field filtering to request only the fields that are needed.

Caching behaviour

Because of the quota costs, we implemented a caching for the calls for each day. The response from the APIs will be saved and used for 24 hours. Normally, the site cache would do it, but it could be, that the cache will be cleared multiple times in a row, or that the plugin is on an uncached page. The TYPO3 registry is used as a cache. The cleanup is handled on the fly.

If the ?disableVimeoCache=1 parameter is added to the URL, this cache will be ignored as well.

.htaccess - Content-Security-Policy

Requires img-src https://i.vimeocdn.com;, script-src https://player.vimeo.com;.

Making changes in JavaScript/CSS

We are shipping the extension with source files and already minified assets. By default, we the minified assets are loaded in the Layout, so that the extension works out of the box just with plug and play. Should you want to change this behavior, you can do the following:

• Override the layout path in TypoScript local/project_theme/Configuration/TypoScript/Extensions/SgVimeo/Constants.typoscript

plugin.tx_sgvimeo {
	settings {
		clientId = MY_CLIENT_ID
		clientSecret = MY_CLIENT_SECRET
	}

	view {
		layoutRootPath = EXT:project_theme/Resources/Private/Layouts/SgVimeo/
	}
}

• Create a new layout file omitting the assets that you would like to change (for example, loading without CSS)

<div class="tx-sg-vimeo">
	<f:asset.script identifier="sgVideoJs" src="EXT:sg_vimeo/Resources/Public/JavaScript/Dist/main.bundled.min.js" />
	<f:render section="main"/>
</div>

• Import the CSS or JavaScript source files in your respective asset pipeline and add them externally.

Compiling CSS/JS assets with SGC

• Install the sgalinski/sgc-core library via composer
• Add the sg-vimeo extension paths in the .sgc-config.json
• Remove the loading of the compiled CSS/JS assets from Resources/Private/Templates/Vimeo/Index.html
• Add import the scss and js module file in the corresponding main.scss and main.js
• Initialize the javascript modules in your main.js: new SgVideoLightbox(); SgVideo.initDefault();
• If you want to recompile the JS with SGC, you must add excludeFromQa: ['!**/Backend/**/*'] to your .sgc-config.js and also set your main extension in extensions to sg-vimeo extensions: ['sg-vimeo']

Compiling SASS only without SGC

Example:

npm install -g sass npx sass ./Resources/Public/Sass/Bootstrap5/main.scss ./Resources/Public/StyleSheets/Bootstrap5/main.min.css --style compressed --no-source-map

Using the Bootstrap 5 templates

If you want to use the Bootstrap 5 templates, you have to first install Bootstrap 5 in your theme to use its styles and JavaScript. Afterwards simply set the plugin.tx_project_theme.config.bootstrapVersion TypoScript setup variable to 5.

Using Events to Customize Vimeo API Results in TYPO3

This documentation explains how to leverage custom events in your TYPO3 extension to manipulate the results of Vimeo API calls. By using these events, you can modify the API parameters, filter results, and further customize the JSON data returned from Vimeo.

Available Events

The following events are dispatched in the Vimeo video rendering process:

1. BeforeVimeoCallEvent
2. AfterVimeoCallEvent
3. AfterFilterVideosEvent
4. AfterMapCustomThumbnailsEvent

Event Listeners

1. BeforeVimeoCallEvent

Description: This event is triggered before making the Vimeo API call, allowing you to modify the API parameters.

Example Use Case: Change API Key or manipulate other paramters

<?php

namespace Vendor\Extension\EventListener;

use SGalinski\SgVimeo\Event\BeforeVimeoCallEvent;

class BeforeVimeoCallEventListener
{
    public function __invoke(BeforeVimeoCallEvent $event): void
    {
        // Change the API key
        $event->setApiKey('your-new-api-key');
        // Extend the max results limit by 10 videos
        $event->setMaxResultsWithFilters($event->getMaxResultsWithFilters() + 10);
    }
}

2. AfterVimeoCallEvent

Description: Add Custom Data to JSON Array

Example Use Case: Change API Key or manipulate other paramters

<?php
namespace SGalinski\SgVimeo\EventListeners;

use SGalinski\SgVimeo\Event\AfterVimeoCallEvent;

class AfterVimeoCallEventListener
{
	public function __invoke(AfterVimeoCallEvent $event): void
	{
        $response = $event->getResponse();
		// Add custom data
		$response['customData'] = 'This is some custom data';
		$event->setResponse($response);
	}
}

3. AfterFilterVideosEvent

Description: This event is triggered after the videos have been filtered, allowing you to further manipulate the filtered results.

Example Use Case: Remove the 10 videos that we added initially with the first event

<?php
namespace SGalinski\SgVimeo\EventListeners;

use SGalinski\SgVimeo\Event\AfterFilterVideosEvent;

class AfterFilterVideosEventListener
{
	public function __invoke(AfterFilterVideosEvent $event): void
	{
		// Modify the response if needed
		$response = $event->getResponse();
		// Add some custom processing here
		// For example let's remove the extra 10 videos that we added in the other event
		if (count($response['items']) > 10) {
			array_splice($response['items'], 0, 10);
		}
		$event->setResponse($response);
	}
}

4. AfterMapCustomThumbnailsEvent

Description: This event is triggered after custom thumbnails have been mapped, allowing you to modify the JSON array one last time before rendering.

Example Use Case: Use a custom thumbnail for all videos in the list

<?php
namespace SGalinski\SgVimeo\EventListeners;

use SGalinski\SgVimeo\Event\AfterMapCustomThumbnailsEvent;

class AfterMapCustomThumbnailsEventListener
{
    public function __invoke(AfterMapCustomThumbnailsEvent $event): void
    {
        $response = $event->geRresponse();
        // Add a custom thumbnail URL
        foreach ($response['items'] as &$item) {
            $item['customThumbnail'] = 'https://example.com/custom-thumbnail.jpg';
        }
        $event->setResponse($response);
    }
}

To enable the events just register them in your Services.php as follows (you can use yaml instead if you prefer):

$services->set(BeforeVimeoCallEventListener::class)
    ->tag('event.listener', ['event' => BeforeVimeoCallEvent::class]);
$services->set(AfterVimeoCallEventListener::class)
    ->tag('event.listener', ['event' => AfterVimeoCallEvent::class]);
$services->set(AfterFilterVideosEventListener::class)
    ->tag('event.listener', ['event' => AfterFilterVideosEvent::class]);
$services->set(AfterMapCustomThumbnailsEventListener::class)
    ->tag('event.listener', ['event' => AfterMapCustomThumbnailsEvent::class]);

Usage in non-composer mode (Classic, Legacy)

This extentension has depdendencies from 3rd party sources that we import through composer. Should you have an installation in legacy mode (non-composer), we need to import these libraries. For this purpose we have the Libraries/ directory where we put the dependencies as PHAR files. You can check how they are used in Services/VimeoService.php.

If the dependencies are updated in composer though, we need to regenerate the PHAR file and commit it again. For this we first pull the new version with composer and then we need to create the PHAR archive by using the following PHP code:

<?php

$pharFile = __DIR__ . '/../sg_vimeo.phar';

// Remove previous PHAR file if it exists
if (file_exists($pharFile)) {
    unlink($pharFile);
}

$phar = new Phar($pharFile);
$phar->startBuffering();

// Add your extension's files
$phar->buildFromDirectory(__DIR__ . '/../sg_vimeo');

// Optionally, add files from the vendor directory
$phar->buildFromDirectory(__DIR__ . '/../sg_vimeo');

// Optionally, set the default stub to load an entry script
$stub = <<<EOD
<?php
Phar::mapPhar();
require 'phar://' . __FILE__ . '/Classes/Main.php';
__HALT_COMPILER();
EOD;

$phar->setStub($stub);

// Stop buffering and save the PHAR file
$phar->stopBuffering();

echo "PHAR file created successfully!";

Once it runs it will create the file and we can commit the new version and use it.

Setting Up the Frontend Filers

Step 1: Adding the Plugin to a Page

1. In the TYPO3 backend, create or edit the page where you want to display Vimeo videos.
2. Add a new content element and select the Vimeo plugin from the list.
3. Provide the necessary Vimeo details in the plugin settings (like Vimeo API key, video/channel/playlist ID, max results, etc.).

Step 2: Disable caching for the extension and Cache validation for your web page

1. In the TYPO3 backend, go to Settings -> Extensions and open the sg_vimeo settings. Tick the box that says 'uncached' and save.
2. This way the the extension will not cache the results and the the data will be loaded dynamically based on the filter settings
3. Set $GLOBALS['TYPO3_CONF_VARS']['FE']['cacheHash']['enforceValidation'] = false in your TYPO3 configuration, otherwise using the frontend filters may result in a 404 page in some instances.

Step 3: Configuring Filters via FlexForm

1. In the plugin's FlexForm settings, you will see a section for "Filters."
2. Depending on your site configuration, filters will be available in a select field. You can select the filters you want to display (like search term, video duration, etc.).
3. Save your settings and publish the page.
4. IMPORTANT! You must make sure that the user associated with the clientId and clientSecret API keys has the right permissions to search in the channel where the filters are being used. Otherwise searching for a query string will always result in an empty result set.

3. Using Filters in the Frontend

Once filters are enabled, they will appear on the frontend in a form, allowing users to interact with the displayed videos dynamically. For example:

• Search Term: Allows users to input a search term to filter videos based on keywords.
• Duration Filter: Provides a dropdown to filter videos by length (short, medium, long, etc.).

The filter values are sent to the Vimeo API, and the video list updates based on the selected criteria.

4. TypoScript Configuration for Filters

To define custom filters, the plugin uses TypoScript. Below is an example configuration and an explanation of each section:

Example TypoScript Configuration

filters {
	searchTerm {
		label = LLL:EXT:sg_vimeo/Resources/Private/Language/locallang.xlf:filter.searchTerm
		partial = Filters/TextField
		filterClass = SGalinski\SgVimeo\Filter\QueryStringFilter
		defaultValues {
#			search = test
		}
		position = top
	}
	duration {
		label = LLL:EXT:sg_vimeo/Resources/Private/Language/locallang.xlf:filter.duration
		partial = Filters/Dropdown
		filterClass = SGalinski\SgVimeo\Filter\DurationFilter
		position = top
		options {
			0 {
				label = LLL:EXT:sg_vimeo/Resources/Private/Language/locallang.xlf:filter.duration.0
				value = 1
			}
			1 {
				label = LLL:EXT:sg_vimeo/Resources/Private/Language/locallang.xlf:filter.duration.1
				value = 2
			}
		}
	}
}

submitButton {
	position = top
	cssClass = btn btn-default
	label = LLL:EXT:sg_vimeo/Resources/Private/Language/locallang.xlf:filter.submitButton
}

Explanation of the Configuration

filters

This TypoScript object defines all the available filters for the Vimeo plugin. Each filter is a separate sub-object, like searchTerm and duration in the example.

Filter Fields

1. searchTerm (Text Field)

   • label: The label for the filter form field. This can be translated using the TYPO3 language file (locallang.xlf).
   • partial: Specifies which partial file to use for rendering the filter. In this case, it points to a text field (Filters/TextField).
   • filterClass: This is the PHP class responsible for processing the filter and applying it to the Vimeo API request. For the searchTerm, it's a QueryStringFilter.
   • defaultValues: You can specify default values for the filter (commented out in the example).
   • position: Defines where the filter should be displayed on the page. It can be top (above the video list) or bottom (below the video list).

2. duration (Dropdown)

   • label: The label for the filter form field.
   • partial: Points to a dropdown partial (Filters/Dropdown).
   • filterClass: This is the PHP class responsible for processing the filter. For duration, it's DurationFilter.
   • options: This section defines the options for the dropdown, each with a label (for the user to see) and a value (sent to the API).
   • position: Indicates where the filter should be displayed on the page.

submitButton

• Defines the configuration for the submit button:
  • position: Determines where the submit button is placed in the form (top in this case). It accepts top, bottom or both
  • cssClass: Adds CSS classes for styling the button.
  • label: Provides the text for the submit button (translatable using locallang.xlf).

5. Adding Custom Filters

You can easily extend the plugin by defining your own filters in TypoScript:

1. Create a New Filter Add a new filter object under filters in your TypoScript setup. For example, if you want to filter by video quality, your configuration might look like this:

   filters {
       quality {
           label = LLL:EXT:sg_vimeo/Resources/Private/Language/locallang.xlf:filter.quality
           partial = Filters/Dropdown
           filterClass = SGalinski\SgVimeo\Filter\QualityFilter
           position = top
           options {
               0 {
                   label = HD
                   value = hd
               }
               1 {
                   label = SD
                   value = sd
               }
           }
       }
   }
   

2. Implement the Filter Logic You will need to define the corresponding PHP filterClass that handles the logic for applying the filter to the Vimeo API request. For example, the QualityFilter class would process the selected video quality and add the appropriate parameters to the API request. It must implement the FilterInterface interface. The modifyRequest method is called before sending the reuqest, while the modifyResponse method is called after receiving the response.

6. Working with Filter Positions

You can choose where filters are displayed (above or below the video list) by setting the position attribute in the TypoScript configuration. This allows you to create a flexible layout for filters:

• Filters with position = top will be displayed before the video list.
• Filters with position = bottom will be displayed after the video list.

For example:

filters {
   searchTerm {
       position = top
   }
   duration {
       position = bottom
   }
}

7. Debugging and Error Handling

If something goes wrong (e.g., videos aren't displayed, or the API request fails), here are a few things to check:

• Make sure the Vimeo API key is correctly configured.
• Check the TypoScript configuration for errors (e.g., missing or incorrect filter definitions).
• Look for error messages in the TYPO3 backend log for issues related to the plugin.

8. Conclusion

With this flexible filter system, you can easily customize the Vimeo video list based on user input. By defining filters in TypoScript and adding them to the plugin's FlexForm, you provide an interactive and tailored experience for your site's visitors.

If you need to add more filters, just extend the TypoScript configuration, create the necessary filter classes, and you're ready to go!
