Hi all,

I'm still relatively new to SilverStripe and have been trying to get to grips with things since 3.0.0 came out. I'm wondering if there's any way of only allowing certain file types to be uploaded with the UploadField? I can't seem to find anything in the API documentation for it.

I'm interested in limiting it to just images (only for an imaginary client's needs). The 'client' will need to be able to upload hundreds of images per DataObject, so I wasn't sure whether UploadField was the best thing to use.

Thanks

Try this:

$myField->allowedExtensions = array('jpg', 'gif', 'png');

I did try that but I can still upload any type of file :/

This is my implementation of it:

$uploadField = new UploadField('Images');
$uploadField->allowedExtensions = array('jpg', 'gif', 'png');

$fields->addFieldToTab("Root.Images", $uploadField);

Thanks

Okay, I've fixed this. In case anyone else gets stuck with it:

This

$uploadField->allowedExtensions = array('jpg', 'gif', 'png');

Should instead be this

$uploadField->getValidator()->allowedExtensions = array('jpg', 'gif', 'png');

I need some docs on this!

silverstripe 3.0.5

do i have to and anything anywhere else?

$uploadField = new UploadField('bannerimage','Banner Image');
$uploadField->setFolderName('Banners');
$uploadField->getValidator()->setAllowedExtensions(array('jpg','svg','png','jpeg','gif'));
$fields->addFieldToTab('Root.Main', $uploadField);

but i cannot upload a svg

i get
Extension is not allowed (valid: {extensions})

some other posts say i need to add a line in mysite/_config.php

eg
Image::$allowed_extensions[] = 'svg';

others say
Config::inst()->update('Image', 'allowed_extensions', array('svg', 'jpg','png'));

SVG is not an image, you should use File as the type for this.

Check that .svg is allowed in assets/.htaccess - if not, add it to the list.

Also consider upgrading from that old version, if you have time :)
