Unable to upload file

This one is hard to be specific about. An uploaded file is validated in several ways, but the message you got is what happens if the file can’t be validated, but there is no specific reason given. php is doing the validation, so it’s a little bit of a black box. Reasons this could be considered invalid would be an incorrect file extension (like a png extension on a jpeg image), some kind of flaw with the file headers, or a file that is corrupt. It can be a problem that doesn’t prevent the image from displaying, so it seems like everything is fine.

Ultimately, it is your server’s php that is validating the file, so it may be due to some reason that is specific to the configuration of your server.

I’m sorry the answer is so vague, there really is little to go on here.

Thanks for your reply. Is there anything I can do to narrow the problem down?

If it helps, I managed to narrow the problem down:

It only occurs with JPG/JPEG files when uploaded through an iPad. Those same files work fine when uploaded from PC. PNG files also work fine when uploaded from the iPad.

However, every file seems to work when uploaded to media (even JPG files from iPad) so I am assuming that this issue has to be related to the plugin.

That’s very interesting. It seems likely the WP Media library is using a different method to verify the files when uploaded…Participants Database is relying on php to verify the files, so the plugin is not directly involved in that at all, it just gets a “go/no go” from php.

Please contact me privately at [email protected], there is something we can try that might help…I don’t want to share it publicly.

Hey,

I debugged a bit, added some logs, and went through the plugin code and am happy to report that the issue is identified and fixed!

The issue was essentially with the file sizes… It seems that the ones on the iPad weren’t working due to coincidence and when I tested the same files I sent them through Facebook Messenger and they must have gotten compressed.

I set the file limit previously in the plugin settings, but apparently this had no effect (or I misunderstood it’s purpose). I finally found the issue within the code that was getting the wordpress limit and halving it for cushioning the limit (I presume). This code set the MAX_FILE_SIZE limit. The JPG files I was uploading exceeded this limit and none of the PNG files did.

So to fix, I simply edited this line of code so it doesn’t half the wordpress limit and gives more allowance to the file size. As well as this, I altered the max file size limit settings related to WordPress.

Maybe the error in the debugger could be a bit better, but who am I to complain :p Thanks for your work. Going to close this and mark as resolved

Wow, thanks very much, and it looks like I need to test this so the plugin can give better feedback when the upload fails.
