Typo3 9.5 prefill form field with get parameter

问题

I use TYPO3 system extension "form" and want to prefill an input field with a GET parameter.

This TYPO3 8.7. Form prefill input field is working, but only is no_cache=1. Is there another solution without deactivate the whole cache?

Thanks david

回答1:

You can disable the cache of the content column of your form page, for example:

lib.content = COA
lib.content{
    10 < styles.content.get
}
[page["uid"] == 512]
    lib.content = COA_INT
[global]

Yes, you can but you need to create HOOK.

This is described in the documentation

For example, the HOOK

/**
 * @param \TYPO3\CMS\Form\Domain\Model\Renderable\RenderableInterface $renderable
 * @return void
 */
public function initializeFormElement(\TYPO3\CMS\Form\Domain\Model\Renderable\RenderableInterface $renderable)
{
    if ($renderable->getUniqueIdentifier() === 'contactForm-text-1') {
        $renderable->setDefaultValue('foo');
    }
}

And the connect the hook

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['ext/form']['initializeFormElement'][<useATimestampAsKeyPlease>]
    = \VENDOR\YourNamespace\YourClass::class;

Please, read the documentation for "Form framework".

I did it and get results what I need.
