[Resolved] A kinda wierd problem with file uploads...

bodzan

...since I don't know when, I was using this file upload script that allows me to upload pictures (or whatever files) that I want, but it's acting strange now...

Well, to say first that in my form I have limite a size of file to 102400 bytes (100 kb).
In my script I start with checking if the file is too big with the line:
if($_FILES['file1']['size']>102400){
//do stuff to warn client that the file is too big
}

Recently (in the mean time I've moved to php 4.3.9), I have a problem with this line because it doesn't do what it was supposed to i.e. I can't seem to get any information to the visitor that is trying to upload bigger file.

When I echoed the $_FILES['file1']['tmp_name'] I got nothing! Like the file I was trying to upload isn't even there!

How can I solve this? I really need to warn my client that the file is too big. I know there is a JavaScript solution to this problem and I implemented it but if a browser isn't JavaScript enabled the problem shows its ugly head...

the problem is that PHP can only check the file size after it's been uploaded. So what's more likely to happen is that your server reaches it's timeout counter (i.e. the script's taking too long to run) before the file has been fully uploaded.

Does that help?

...because the script is still being tested on my home machine and it finishes within seconds...

I figured that the limitations set in MAX_FILE_SIZE input field are causing this but the situation didn't change even when I deleted this field...

I should point out that the file I was trying to upload is 105 kb's (some 5 kb's more than allowed)...

I used to do this in my code before (well, last time I needed it is some year and a half ago) but now it works like I said... 😕

Is there even a way to do this?

Am I missing something obvious?

I've learned that JavaScript can't do this (I don't know where I got idea that it could...):bemused:

Anyway since there were some 31 views of this thread and only one reply I conclude that this really can't be done... 🙁

Thnx anyway, guys (and girls)...

I used
import_request_variables("P", "$submit");
to import all the data from the form so I can use them as a plain variables...

Well, I have to say next step confused me. The variable that hold the data from the upload file field of the form is never empty but instead is an Array (!)...:queasy:

Lets say the upload file field is named file. So, the Array $file will hold values in following keys: name, type, tmp_name, error and size... They are pretty much self explanatory so I won't bother explaining them additionally.

The values of the Array elements are never the same and they go like this:

When the uploaded file filed is empty (i.e. nothing offered for upload) the values are:
name ""
type ""
tmp_name ""
error 4
size 0

If the file offered for upload is something meaningful the values are:
name /name of the file/
type - mime type of the file i.e. image/jpeg for jpeg image file, application/msword for word document file...
tmp_name /whatever name was givven to the file in temp folder/
error 0 /this means that something was offered for upload/
size /the size of the file in bytes offered for upload/

If the file offered for upload is .exe, .fla or .zip (well, at least I tested these) or the file is too big (bigger than the max_file_upload form field), the values are:
type /name of the file/
tmp_name ""
error 2 (or 1 - I didn't catch when is which)
size 0

This way I could determine whether the file was too big or was of the wrong type...:p

Maybe I am stupid but I tried the same with $_FILES['file'] (if you don't import variables ycan use this way) stuff, but I missed the concept that this array is never empty...:rolleyes:

Hope you find this usefull...
