Hi,
MP2 RC5, Template, Image::Magick
I hope this is not off topic, apologises if it is.
I have a perl script written as a handler. It scans a dir for image
files and offers the user a chance to convert them from tiff to jpeg.
As there can be lots of files of some size, it can take some time for
the process to return.
What I wanted was to loop through the files and refresh the page as
each file was processed. So I had something like;
$r = shift if $ENV{MOD_PERL};
my $tt = Template->new...
foreach my $f (@files) {
my @files_processed;
...snip
push(@files_processed,$f);
my $vars = {
files => [EMAIL PROTECTED],
};
$r->content_type('text/html');
$r->headers_out;
$tt->process($tt_file,$vars)
|| die $tt->error;
} # End of foreach
# $r->headers_out;
I thought this would re-send the $vars and headers_out until the list
was exhausted but in practise what I get was the page repeated for
each file. EG: if there are 4 files I get 4 <html></html> and a messy
looking page.
I am not sure what I am doing wrong. If I move the headers_out
outside the foreach loop I get to the array contents but I still get
the (size of @files_processed) x <html> tags rather than one nice
page and I still have to wait for the whole process to complete.
I imagine I am going to have to take another approach but can't thing
of one. Does anyone now how to refresh a referring page or loop in
the may I described?
Thanx in advance.
Dp.
