)
)
)
)
and I need to get the [url] value (which in this one is http://mydomain.com/my/link)
I tried to follow a tutorial and ended up with this:
print $row->field_field_slider_link[0]['raw']['url']
but I get this error message:
Notice: Undefined offset: 0 in include() (line 57 of /var/www/vhosts/clientname/public_html/sites/all/themes/custom/templates/views/ff-nivo-slider/views-view-fields--ff-nivo-slider.tpl.php).
can anyone see what i'm doing wrong here?
Thanks

Answer 1

The array your code runs with is not the one you expect. Check the value of $row->field_field_slider_link. Chances are that it's an empty array.
