Rayner, 2003 # # This is a CGI script to convert Apple iPhoto-exported # thumbnail galleries into a slicker-looking XHTML/CSS based # layout. Minor editing by the user is required: The DATA # section at the bottom of this script holds values for each # gallery in a |-delimited table format. Required parameters # include: (1) a keyword identifier, matching the name of # the directory which holds the three "-Pages", # "-Thumbnails" and "-Images" directories produced by # iPhoto; (2) the actual title of the gallery to be used in # the generated HTML; (3) the total number of photos in the # gallery (this seems safer than automatically detecting the # number of images available); (4) the background colour # to use (I prefer a centralised location for such things) # in the standard #nnnnnn hexadecimal form (other forms # usable in CSS should also work, but are untested); and # (5) a 'subdirectory' term, for when the individual gallery # page is held in a subdirectory of the top-level directory. # An example of the directory organisation: # # /var/www/htdocs/photos/spain/madrid # /var/www/htdocs/photos/spain/barcelona # /var/www/htdocs/photos/wedding # /var/www/htdocs/photos/vacation # /var/www/htdocs/styles/photos.css # # You should also set the variables $docroot, $galleryroot # and $stylesheet. # For the example above: # # my $docroot = "/var/www/htdocs"; # my $galleryroot = "/photos"; # my $stylesheet = "/styles/photos.css"; # # In this case, the wedding and vacation galleries are in # the top level and so do not require subdirectory # information; however, the various spain galleries are in # the spain subdirectory and therefore require entries in # the DATA section such as: # # madrid|Photos of Madrid|24|#fdffbc|spain # # Finally, the script is called as: # # http://your.domain.org/photos/index.pl?page=madrid&index=1 # # This assumes you call the script index.pl and put it in # the /photos directory; you can call it anything you want # and put it anywhere you like, however. # # (From there, the rest should be obvious - I hope!) # ### BEGIN USER CONFIG ### my $docroot = "/var/www/htdocs"; # Path to webpages on the serve +r my $galleryroot = "/photos"; # Path from $docroot to where t +he galleries are my $stylesheet = "/styles/photos.css"; # Path from $docroot to where t +he stylesheet is my $rowno = 5; # Number of rows in the thumbnail galleries my $colno = 3; # Number of columns in the thumbnail galleries ### END USER CONFIG ### - But also see DATA section at end of script! sub parsedata{ # Get the relevant <DATA> # Takes: $cgi->param("page"), as passed to it # Gives: hashref containing all the data parsed from <DATA> for the +given page my $target=shift; while (my $line=<DATA>){ chomp $line; my %data; ($data{page},$data{title},$data{number},$data{bkgd},$data{subd +ir})=split /\|/,$line; return(\%data) if ($target eq $data{page}); } } sub drawindex{ # Draw an index page # Takes a CGI object, a data hashref (originally from &parsedata), # the number of columns and rows desired in the index table (this +is # trucated as necessary to match the total number of pictures in # $data{number}. my ($cgi,$dataref,$colno,$rowno)=splice(@_,0,4); my %data = %{$dataref}; my $idxno = POSIX::ceil($data{number}/($colno * $rowno)); my $index = $cgi->param("index"); my $prev = $index-1; my $next = $index+1; my $pageroot = "$galleryroot/$data{subdir}/$data{page}"; # Where t +he thumbnail, page and image dirs are my $url = $cgi->url(); # Check our index is in range unless ($index > 0 && $index <= $idxno){ print $cgi->h4("Error in CGI input: index out of range."); return 0; } # Get the thumbnail titles my @alt; for (my $i=1; $i <= $idxno+1 ; $i++){ my $tmpidx = $i - 1; my $indexfile = ($i == 1) ?
