Re: [mv] Loop Search part 2 :)
****** message to minivend-users from Victor Nolton <ven@pragakhan.com> ******
I sended up using someone elses suggestion, which was look at the
browse page. I've copied the code and changed the page name. yet the
next and previous buttons act totally weird.
next is displayed on the first page, and on the second and previos is
displayed on the 3rd page. though on the last page there are a bunch
of extra rows with no data, but the formatting is there incase there
actually would be items.
Very odd. I guess I broke part of the simple demo
I call it with this..
<A HREF="[area href=seastories2 arg='0:12']">test</A>
[perl arg=scratch]
$start = tag_data('session', 'arg') || 1;
$chunk = 1;
if($start =~ /(\d+):(\d*)/) {
$start = $1;
$chunk = $2 || 1;
}
$prev = $start - $chunk;
if($prev < 1) {
$prev = 0;
}
$Safe{'scratch'}{'start'} = $start;
$Safe{'scratch'}{'chunk'} = $chunk;
$Safe{'scratch'}{'next'} = $start + $chunk;
$Safe{'scratch'}{'prev'} = $prev;
$Safe{'scratch'}{'not_shown'} = 1;
return '';
[/perl]
[search-region arg=" sf=section
se=001-
su=yes
fm=[scratch start]
ml=[scratch chunk]
dp=seastories2
tf=section
"]
[search-list]
<html removed>
[/search-list]
[/search-region]
<TABLE WIDTH="80%"><TR __HEADERBG__ TEXT="WHITE"><TD ALIGN=CENTER
VALIGN=CENTER>
<BR><FONT COLOR="__HEADERTEXT__" FACE="arial, helvetica">
[if scratch prev]
[page href=seastories2 arg="[scratch prev]:[scratch chunk]"]
<B>[L]Previous[/L]</B></A>
[/if]
[if type=explicit compare="[calc]
[value mv_search_match_count] > [scratch next]
[/calc]"]
[page href=seastories2 arg="[scratch next]:[scratch
chunk]"]<B>[L]Next[/L]</B></A>
[/if]
