I can not download file more 2 Mb but upload_max_filesize 32M (php.ini)
And does not get messages about it.
How to increase the limit on file upload?


What is the post_max_size value set to in php.ini? Both it and the upload max filesize typically need to be large enough to allow bigger file uploads, I would assume that also applies with this upload method.

Actually, now that I look at the plupload js library docs, this is probably a setting that needs to be adjusted for it, rather than for php..

These two items jump out as relevant to me:

Maximum file size that the user can pick. This string can be in the following formats 100b, 10kb, 10mb.
Enables you to chunk the file into smaller pieces for example if your PHP backend has a max post size of 1MB you can chunk a 10MB file into 10 requests. To disable chunking, remove this config option from your setup.

It looks like there's a hard-coded 10mb file size limit in plupload.module. I don't know if that was causing the problem in the original post, but it certainly isn't helping. Here's a patch that implements site-specific limits for max_file_size and chunk_size.

I think this is ready to go in, with making it configurable as a follow-up.

One question, in reading the PHP docs: do we need to account for ini.memory_limit when calculating these values? It would seem proper. http://www.php.net/manual/en/ini.core.php#ini.post-max-size

I can't tell from the PHP docs whether we should take memory_limit into account or not. On the one hand, it sounds like something the sysadmin should be managing. On the other hand, if the chunk size is bigger than memory_limit things will explode quite prettily.

Yeah, so I would think we should cap chunk size. Oddly, however, file_upload_max_size() seems to ignore that, too.

Do we know why core doesn't use memory_limit? That would answer the question.

Also see #1060448: Support for max upload size and resize parameters which is solving the same problem but adds configuration. Personally I'd favor of getting this patch in quickly and then moving on to making the values configurable in the other issue.

RTBC then.

@agentrickard Yup, I'd say so. I just tested with a 200MB file without problem.

Re #8: I think contrary to the other request for having this be a configurable value this is the right way to do it.. These settings should ideally be managed by the sys admin in my opinion. The only instance I can think of that that wouldn't be the case would be in the instance of shared hosting, but then the settings are likely limited to too small an amount anyway, so config to try and change those settings wouldn't be useful anyway.

I think the patch as provided in #3 is probably the best solution here.


Which is why the two issues are decoupled. That debate needs to happen in the other issue.

@slashrsm Excellent news! I noticed that a number of other helpful patches have gone in recently. Any chance that another beta release is around the corner? It always feels good to remove patches from make files. :)

Latest release (beta4) includes most of the patches I commited last weekend. As soon some other patches are commited I plan to release another release. If it's going to be another beta or rc depends on number of new issues that appear.

I didn't realize that there was already a new release made on the 18th. Thanks!


I agree with this patch - but just note that if php upload_max_filesize is less than 10mb people using this module will now have a reduction in max file size after this patch. 10mb would have been no problem earlier, even with upload_max_filesize set to 2mb, as it was chunked down to 1mb.

This is only really a problem using the buildt in uploader, though, as modules implementing this field element can set their own limits. E.g. in FileField Sources Plupload the limit set on the field instance - allowing one to upload files regardless of php limits.

That is another reason for not making this a configurable setting, as if could potentially confuse the user if they set 50mb in Plupload settings, but the module using the field has its own settings.

Hm... that's strange. How did this happen... Anyway, thank you for this.

I think we need to add 'b' at the end. See patch....
