[SOLVED] Extract EXIF information before uploading

[ryanlin]

Hi,

 

I am just wondering whether I am able to extract EXIF information from photo before actually uploading it to the server.

Because I have to do some validation whether user can actually upload that picture using EXIF info.

 

Thanks

You can't. At least not with PHP. Before PHP can do anything with a file, it must be uploaded to the server. After it's been uploaded you can do any tests you want.

I expected this answer. I am finding a solution actually to solve this and below is the first one I come up with -

 

User upload the picture to a temporary folder > validate the EXIF info > if correct the picture will be move to permanent folder, if not I will set the cronjob or with php, I will delete all the images inside that temporary folder at a time interval, let say every 5mins .

 

What do you think about this solution?

 

Thanks

That's ok, but why bother with a cron job? If the file can't be used, let the PHP script delete it using the unllink() function.
