NAME

       Ace::Browser::SearchSubs - Subroutines for AceBrowser search scripts

SYNOPSIS

	 use Ace;
	 use Ace::Browser::AceSubs;
	 use Ace::Browser::SearchSubs;
	 use CGI qw(:standard);

	 my $form = p(start_form,
		      textfield(-name=>'query'),
		      end_form);
	 AceSearchTable('Search for stuff',$form);
	 ...

	 my $query  = param('query');
	 my $offset = AceSearchOffset;
	 my ($objects,$count) = do_search($query,$offset);
	 AceResultsTable($objects,$count,$offset,'Here are results');

DESCRIPTION

       Ace::Browser::SearchSubs exports a set of constants and subroutines that are useful for creating AceBrowser search scripts.

   CONSTANTS
       This package exports the following constants:

	 MAXOBJECTS	The maximum number of objects that can be displayed
			per page.

	 SEARCH_ICON	An icon to use for search links. This is deprecated.
			Use Configuration->Search_icon instead.

   FUNCTIONS
       These functions are exported:

       $offset = AceSearchOffset()
	   When the user is paging back and forth among a multi-page list of results, this function returns the index of the first item to
	   display.

       AceSearchTable([{hash}],$title,@contents)
	   Given a title and the HTML contents, this formats the search into a table and gives it the background and foreground colors used
	   elsewhere for searches.  The formatted search is then printed.

	   The HTML contents are usually a fill-out form.  For convenience, you can provide the contents in multiple parts (lines or elements) and
	   they will be concatenated together.

	   If the first argument is a hashref, then its contents will be passed to start_form() to override the form arguments.

       AceResultsTable($objects,$count,$offset,$title)
	   This subroutine formats the results of a search into a pageable list and prints out the resulting HTML.  The following arguments are
	   required:

	    $objects   An array reference containing the objects to place in the
		       table.

	    $count     The total number of objects.

	    $offset    The offset into the array, as returned by AceSearchOffset()

	    $title     A title for the table.

	   The array reference should contain no more than MAXOBJECTS objects.	The AceDB query should be arranged in such a way that this is the
	   case.  A typical idiom is the following:

	     my $offset = AceSearchOffset();
	     my $query	= param('query');
	     my $count;
	     my @objs = $db->fetch(-query=> $query,
				   -count  => MAXOBJECTS,
				   -offset => $offset,
				   -total => $count
				  );
	     AceResultsTable(@objs,$count,$offset,'Here are the results');

BUGS

       Please report them.
