[RESOLVED] File Upload issue

baffled_in_UK

Hi
I have a form where a user can upload an image file, the file can be any size (up to 16Mb) and I then resize it on the fly, however if I test it with small'ish files (less than 1Mb) it works fine but when I try with larger files (eg, 2.7Mb) it fails with my error message saying ' Please upload a photo' so it appears the script hasn't got the file?

I have the following at the top of the upload script :-

ini_set("memory_limit","32M");
ini_set("post_max_size","16M");
ini_set("set_time_limit","3600");
ini_set("max_execution_time","3600");
ini_set("max_input_time","3600");

Am I missing something ?

Thanks for any help.

What's the error code? See: [man]features.file-upload.errors[/man].

EDIT: Oops, didn't read your post carefully enough.

You can't set those directives from within your script. When the file is uploaded, PHP will have already discarded it based on the settings of those directives before your script has ever been executed. Either make the changes in php.ini or (if possible) in a .htaccess file in the root of your site.

My understanding of ini_set is that it will keep this new value during the script's execution?

I have seen several instances in other posts where people have needed to change the max_upload_size and this is the method given to do it. So I don't understand why you say they will cannot be set during the script?

Yes, but that's not the problem. PHP will already have received the file but then discarded it due to size restrictions before it parses and executes your script. So you're only changing the size restriction after the file has already been processed and analyzed (and, in this case, deleted) by PHP - not very helpful.

Care to provide a link (or links) to such posts?

EDIT: Even if you don't believe me (BLASPHEMY! :p), take it from the manual; visit the [man]ini.list[/man] page and look up the max_input_time, post_max_size, and upload_max_filesize PHP directives. All have a 'configurable' value of PHP_INI_PERDIR which, as explained by this page: [man]configuration.changes.modes[/man], means:

PHP Manual wrote:
Entry can be set in php.ini, .htaccess or httpd.conf

Note that [man]ini_set/man (or anything else you can do inside a PHP script) doesn't appear in that list of options.

No intention to commit blaspemy, just wanted clarification 🙂

I've gone down the route of creating a php.ini file

Thanks for your help.
