Hi I've got a website thats all but done, all I need to do is the image gallery, I'm looking at using this one ... this is my first website using SilverStripe so still figuring things out.
I downloaded the DataobjectManager and SWFUploadField Modules and unpacked them into the root folder as instructed, ran dev/build (tried db/build too with the same result) and i'm getting the following:

Warning] fopen(C:\Windows\TEMP\/silverstripe-cacheC--Users-Krissy-Work-Web-wamp-www-Kenpo-silverstripe-v2.3.4/manifestClassParse-C__Users_Krissy_Work_Web_wamp_www_Kenpo_silverstripe-v2.3.4_modules-dataobject_manager-r371_code_simple_html_editor_field_SimpleHTMLEditorField.php) [function.fopen]: failed to open stream: No error

Can anyone point me in the right direction of what the problem is and how to fix it ?
I'm using Silverstripe version 2.3.4 running on WAMP server version 2.0.

Thanks

Looks like a permissions issue to me. fopen() needs that file to be writable. Also, I would just do a sanity check and make sure the file exists, as well.

Hey thanks for the reply. How do I check permissions? And what exactly am I checking permissions on?
I had a look for the file C:\Windows\TEMP\/silverstripe-cacheC--Users-Krissy-Work-Web-wamp-www-Kenpo-silverstripe-v2.3.4/manifestClassParse-C__Users_Krissy_Work_Web_wamp_www_Kenpo_silverstripe-v2.3.4_modules-dataobject_manager-r371_code_simple_html_editor_field_SimpleHTMLEditorField.php that comes up in the error and it appears it does not exist.
As far as I can gather the manifestbuilder.php file is supposed to create that file when you dev/build .. am I right?

Well just for testing, you can open up your whole web root to 777. That should eliminate any questions.

Using wamp server on localhost so I can't use chmod permissions, have made sure all the 'read-only' boxes are unchecked in the file properties but that didn't help. Are there any other permission settings hidden somewhere?

I just noticed the filepath in the error has a combination of forward and back slashes in it, could that be the problem? and if so how would i go about fixing that?

All the permissions seem to be fine, and have looked through the cache files and it's written half the files there for the dataobjectmanager so permissions don't seem to be the issue. Still getting the exact same error tho.
Any help would be apprecated.

Yeah, I had a client report this issue, and I tracked it down to the failed write to the /tmp/ dir. You can test it by putting SWFUpload in debug mode, and editing /sapphire/filesystem/Upload.php:

Line 85 (in 2.3.6)

		if(!$tmpFile['size']) {
die(print_r($tmpFile));
			$this->errors[] = _t('File.NOFILESIZE', 'Filesize is zero bytes.');
			return false;
		}

After an upload, you'll see the alert message come up with the output of the $tmpFile resource, including error #7, which is UPLOAD_ERR_CANT_WRITE.
