[BUG] Multi-Dimensional Values

[Roritchi]

In EXT:form it is possible for Values in the $valuesWithPages, to have multiple Levels.
This would cause those Variables to not be set in the returned Value of getFormValues(). (SaveFormToDatabaseFinisher.php)

If you want to reproduce this problem, you can try using the "repeatable container" form extension for typo3.

To fix this, we have to traverse the given path, which has dots in it, through the array.
With this simple Function, this works:

protected function traversePath($conf, $path) {
        // We split each word seperated by a dot character
        $paths = explode('.', $path);
        $result = $conf;
        foreach ($paths as $path) {
            $result = $result[$path];
        }
        return $result;
    }

    /**
     * Returns the values of the submitted form
     *
     * @return []
     */
    protected function getFormValues(): array
    {
        // All values, with pages
        $valuesWithPages = $this->finisherContext->getFormValues();
        $values = [];

        // Goes trough all form-pages - and there trough all PageElements (Questions)
        foreach ($this->finisherContext->getFormRuntime()->getPages() as $page) {
            foreach ($page->getElementsRecursively() as $pageElem) {
                if ($pageElem->getType() !== 'Honeypot') {
                	if($pageElem->getType() !== 'FileUpload' && $pageElem->getType() !== 'ImageUpload'){
                        $values[$pageElem->getIdentifier()]['value'] = $this->traversePath($valuesWithPages, $pageElem->getIdentifier());
	                }else{
                		if($valuesWithPages[$pageElem->getIdentifier()]){
			                $values[$pageElem->getIdentifier()]['value'] = $valuesWithPages[$pageElem->getIdentifier()]->getOriginalResource()->getName();
		                }
	                }
                    $values[$pageElem->getIdentifier()]['conf']['label'] = $pageElem->getLabel();
                    $values[$pageElem->getIdentifier()]['conf']['inputType'] = $pageElem->getType();
                }
            }
        }
        return $values;
    }
