How to only show a more link if there's actually more content?
15 April 2011 at 9:09pm
I'm stuck with a little programming problem and don't know how to proceed.
I only want to show a more link on a news if there is actually more content than just the first paragraph. Something like
<% if Content > Content.FirstParagraph %>
but as i know that the templating language doesn't support comparisons just jet, i tried to write this in my NewsList Controller, but i think my function never gets called, so i wonder if i'm making anything wrong?
function HasMoreContent() {
if ($this->obj('Content')->FirstParagraph()
&& $this->Content > $this->obj('Content')->FirstParagraph()) {
return true;
} else {
return false;
}
}and in the template:
<% if Content %>
<% if HasMoreContent %>
<a href="$Link" title="Mehr über "{$Title}""> >> mehr</a>
<% end_if %>
<% end_if %>i also tried something like this, just to see if anything gets called at all
function HasMoreContent() {
print "test";
return "Test";
}and in the template:
$HasMoreContent
Any hints on how to proceed would be greatly appreciated.

Regarding your function not getting called - I think it might be a context/scope thing. I'm guessing you have something like a NewsList page type and a NewsArticle page type? In that case I think the HasMoreContent() function should be on your NewsArticle controller instead of your NewsList controller.
