Auto-update image upload directory
3 December 2012 at 7:31am
Hi all,
I've hit a bit of a snag which I'm sure has a simple solution, but I can't for the life of me figure it out. I have a page with an image upload field, and I need the upload directory to be /[parent page->URLSegment]/[URLSegment]/. At the moment I'm doing this with UploadField->setFolderName() in getCMSFields(), but this of course only changes the upload directory when the page is saved. Ideally I want it to change as soon as the URLSegment changes, just like the URLSegment does when the Title is changed.

You should be able to do this in the 'onBeforeWrite()' functions of the different pages.
Have a look at this code:
public function onBeforeWrite() {
parent::onBeforeWrite();if($this->isChanged('Title')) {
$this->URLSegment = $this->createUniqueURLSegement();
}if($this->isChanged('URLSegment')) {
$fields = $this->getChangedFields();
$URLSegment = $fields['URLSegment'];
$pdfFolder = Folder::find(self::$pdf_folder . '/' . $URLSegment['before']);
if($pdfFolder) {
$pdfFolder->setName($URLSegment['after']);
$pdfFolder->write();
}
$imageFolder = Folder::find(self::$image_folder . '/' . $URLSegment['before']);
if($imageFolder) {
$imageFolder->setName($URLSegment['after']);
$imageFolder->write();
}
}
}Here I do exactly what you want and it seems to work. Basicaly i have several AnnualProgramms with several events. So every time the title of an annualprogramm changes i change the URLSegment and remane all folders which are affected by the renaming.
