Custom file processors¶
For custom needs in terms of file processing, registration of custom file processors is available.
Create a new processor class¶
The file must implement the \TYPO3\CMS\Core\Resource\Processing\ProcessorInterface
and two required methods.
canProcessTask()
Will decide whether the given file should be handled at all. The expected return type is boolean.
processTask()
Will then do whatever needs to be done to process the given file.
Register the file processor¶
To register a new processor, add the following code to ext_localconf.php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['fal']['processors']['MyNewImageProcessor'] = [
'className' => \MyVendor\ExtensionName\Resource\Processing\MyNewImageProcessor::class,
'before' => ['LocalImageProcessor'],
];
With the before
and after
options, priority can be defined.
Note
Only one file processor will handle any given file. Once the first match for canProcessTask()
has been found, this is the
processor that will handle the file. There is no cascading or sequence possible, so make sure your processor does all the work
necessary.
