logic help

I have a situation where the end user can browse to ONE image path in the dct.
Yet the image is a rollover so in the tpl it needs to come out as two image paths.
lets call the image "imagename_on.gif" and the offstate image "imagename_off.gif".
Where would the logic go? Regex in the dct? Something in the tpl? Perl?

Thanks,
Nico

If you have strict naming standards in place such that you can always assume that [whatever]_on.gif always corresponds to [whatever]_off.gif, you could have the user only select the onstate image. Then in the presentation template (.tpl) you could do a substitution regex on that value to get the offstate image name.

If you do not have the strong naming conventions, you may have to have a browse button for each image.

I too have a strict naming convention in place actually it will always be "_over." or "_off." can you show me a code example of how you incorporated the regex in the tpl?

Hi nico,

This code will display the XML stored in the "News Blurb" field in my HTML page's < TITLE> tag if it exists, and the XML stored in the "Headline" field in my HTML page if the "News Blurb" doesn't exist.

This example should show you how you can assemble a [whatever]_on.gif and a [whatever]_off.gif:


        iwpt_output("< TITLE> News Archive: ");

        my $newsblurb = iwpt_dcr_value('dcr.PR.News Blurb');
        if($newsblurb ne "" && $newsblurb ne undef) {
           $newsblurb =~ s/[a-z]/[A-Z]/;
           iwpt_output($newsblurb);

        } else {
            my $headline = iwpt_dcr_value('dcr.PR.Headline');
               $headline =~ s/[a-z]/[A-Z]/;
            iwpt_output($headline);
        }

        iwpt_output("");

In your example, you can probably have something like:


my $img_base_name = iwpt_dcr_value('dcr.IMG.URL');
my $img_on = ""; 
my $img_off = "";
if($img_base_name =~ /(.*)_on.gif/) {
    $img_on = $img_base_name;
    $img_off = $1 . "_off.gif";
} elsif($img_base_name =~ /(.*)_off.gif/) {
    $img_on = $1 . "_on.gif";
    $img_off = $img_base_name;
} else {
    warn "Don't know what to do with $img_base_name $! \n";
}

Hope that helps.
Tom
