Using Perl - you could make a stat() call on the full-path to the PDF and pull out the size information into a variable which can then be put into the generated output.

my @st = stat($pdf);
iwpt_output("Size: $st[7] bytes<br>");

If you want, you could do something a bit fancier and calculate the size in different units.

my @st = stat($pdf);
my $size = $st[7];
my $units = "bytes";
my $tmp;
if (int($tmp = $size / (1024*1024*1024)) > 0){
    $size = $tmp; $units = "Gb";
}
elsif (int($tmp = $size / (1024*1024)) > 0){
    $size = $tmp; $units = "Mb";
}
elsif (int($tmp = $size / 1024) > 0){
    $size = $tmp; $units = "Kb";
}
if ($size =~ /\./){
    iwpt_output(sprintf("Size: %2.2f %s<br>", $size $units));
}
else {
    iwpt_output("Size: $size $units<br>");
}

thank you, it works fine

what happens when (if) the PDF file is updated?
The page needs to be regenerated or it will still be showing the old file size, right?

Adam Stoller

As written here - the page is static, and thus yes - it would have to be regenerated.

You could probably do similar code in ASP/JSP/whatever - and pay the price of doing the calculation everytime the web page was viewed if you wanted to do so.

Hi,

I saw your post regarding filesize. I want to find out file size on DCT.

I have two items in my dct. Once is LINKTOFILE with Browse buttion Next one is FileSize.

When user selects LINKFILE i need to calculate and set filesize automatically.

Could pls. give me any idea how to do this??

Thanx in advance

I'd suggest trying to find javascript equivalents to the Perl code I posted - then you can do it as FormAPI code in the DCT. I don't know the way to do that in Javascript off-hand, sorry.

Has anyone have the code for this?

I have a DCT that allows a user to attach 5 files via browse button.

I need to find the javascript code to find out the file sizes of those files (in KB 2 decimal places).

As always thanks in advance

You're not going to find a pure javascript solution to determine the file size of a client upload. The only way to do this is through server-side script once it is uploaded or a client-side ActiveX component such as VisualFormat.

Why is this? Security. It would be a flaw and would be exploited.

I have FormAPI that does a callServer to a CGI to populate the size field as needed (onChange). But I would probably get the file size in the TPL instead if possible.

I realized it after I posted it that javascript wouldn't work.

Was going to do it in the tpl but some of my DCT's are not using tpl's just DD.

Finally I did it in the external task of the workflow where a call is made to submit the attachments.

Used the perl code in the beginning of this post and XML: Smiley Very Happy

OM to write it to the DCR.

Man I wish there was better examples then

It works but it is a little clunky...

Any one got code out there that does it better
