php to retrieve child nodes
Permalink
OK, I'm very very new to php.
I need to retrieve a datum field 'url_thumbnail' from an external site.
The following code works fine, apart from retrieving the image field. I'm guessing this is because (on the external site) the 'url_thumbnail' datum field is a child node of 'image' which is a child node of 'images'. I just don't know how to write this in php...?
$image = $tour->image.''; (I think I need to change this line of code...?)

So, if you need to retrieve a node (e.g. url_thumbnail) which is child of 'image', which is a child of 'images'
rather than something like $image = $tour->url_thumbnail.'';
you would use
$image = $tour->images->image->url_thumbnail.'';
and then echo the value
echo "<img src='".$image."'/><br />";
