logic for image caption

pieman · 2008-04-18 11:25:06

I’d like to prepend a copyright symbol to the caption of an image. The symbol shouldn’t appear if not caption has been added.

I tried using a combination of chh_if_data and upm_image, but the © is output in all cases – whether or not a caption exists.

<p class="credit"><txp:chh_if_data>© <txp:upm_img_alt /></txp:chh_if_data></p>

Is there another way to achieve this?

thanks
Stu

shouldn’t you be using <txp:upm_img_caption /> ?

yes, sorry – my typo
the same problem applies though

<p class="credit"><txp:chh_if_data>© <txp:upm_img_caption /></txp:chh_if_data></p>

And if for some reason chh_if_data doesn’t work, as it could be, but the changes are quite small, then you can use little tiny php statement:

<txp:php> if(upm_img_alt(array())) echo '&copy; '; </txp:php>

Expecting that upm_img_alt is a function and not formed by custom parser – it definetly should be function, shouldn’t it? :)

my apologies – the chh_if_data plugin does work – I was being a numpty ;-o
sorry to waste your time

So, what was the problem?
