README

This module adds a screenshot preview of a page to the search results.

PhantomJS

PhantomJS is required in order to capture the screenshots.

To automate installing PhantomJS you can use the package jakoch/phantomjs-installer. Once installed, add PhantomInstaller\\Installer::installPhantomJS to the post install and update commands of your project's composer.json:

"scripts": {
    "post-install-cmd": [          
        "PhantomInstaller\\Installer::installPhantomJS"
    ],
    "post-update-cmd": [
        "PhantomInstaller\\Installer::installPhantomJS"
    ]
}

Now when you run composer install, PhantomJS will be automatically installed to /vendor/bin/phantomjs.

If you wish you can use a custom instance of PhantomJS by downloading it from https://phantomjs.org/. If you do this you may need to set a custom path for PhantomJS under Settings.

Usage

Generating screenshots

In order to generate the screenshots, a server cron job must be set up that runs the following command every minute:

vendor/bin/contao-console search-screenshot:generate

If you don't wish to wait, you can manually trigger the generation of screenshots for all pages from the CMS backend under System > Search screenshots.

Screenshots will be automatically updated every 7 days.

Displaying screenshots in results

The module makes a new variable $this->screenshot available in the search results template. This variable will hold the URL of the screenshot if it exists or be empty if not.

A template which includes the screenshot is included and can be selected when configuring the search module. Select search_with_screenshot.html5 as the search template to use it.

Configuration

Under System > Settings you will find some configuration options for the module in the "Search screenshot configuration" section.
