Conditional tags

[Geekess]

Maybe this belongs under "Templates" and not under "Help"...
I would like to know how to use template-tags in conditions.
E.g.: Check whether a tag (previous thumbnail or IPTCfield or anything) contains any data, if so, do one thing, if not do another thing.
How can I do this?

I'm using Pixelpost v.1.5beta under FreeBSD with PHP/Apache.

you can do this all in an addon. for example, i use the following script just for my comment popup:

PHP Code:

<?php 

$addon_name = "Comment link";
$addon_description = "the comment link";

$addon_version = "0.1";

if    ($image_comments_number >1) 

            $comment_word = "Reactions";
            
else
            $comment_word = "Reaction";
            
if ($image_comments_number <1)
            $comment_word = "Reactions";

$tpl = ereg_replace("<COMMENT_LANG>","$comment_word",$tpl);

?>

by the way. looking at that that has to be the worst written piece of php in the whole world! hehe.

Thanks!
And I did SO hope that wouldn't be the solution... It means I have to write a lot of add-ons :-)
Well, I'd better get on with it.

You can write all things in to one addon I'm doing it - all modyfications I put to one addon file.
