Hi all,
Some more basic PHP help requested [I know, I really should go to a PHP forum for this stuff :-)]
For a vocabulary with only one term allowed, taxonomy module can return you that information via
http://api.drupal.org/api/function/taxonomy_node_get_terms_by_vocabulary
.
That returns something like this
<?php
#
... (Array, 1 element)
*
125 (Object) stdClass
o
tid (String, 3 characters ) 125
o
vid (String, 1 characters ) 3
o
name (String, 6 characters ) Dublin
o
description (String, 0 characters )
o
weight (String, 1 characters ) 0
?>which is basically one object, the term, inside an array.
Because its a keyed array, with the tid as the key, I can't just go
<?php
return $county[0]->name;
?>I'm guessing there is a better way to access that data rather than what I currently do, which is a bit convoluted, to say the least.
<?php
$county = taxonomy_node_get_terms_by_vocabulary($vars['node'],3);
foreach ($county as $item) {
$countyname = $item->name;
}
?>Any input appreciated?
Regards
Alan

try this
If the snippet is for use in a theme, you could try this..
<?phpforeach ($node->taxonomy as $term) {
$countyname = $term->name
}
?>
I haven't tested that....it's just a guess...but, if it works, it avoids the need to make a database query using
taxonomy_node_get_terms_by_vocabulary....i,.e. it assumes the taxonomy module has already queried the database for all the terms associated with the node..allowing you to pull the term name value straight out of the$node-taxonomyarray.dub
Good idea
Hi Dub
Yep, that would work if I had only one vocabulary [with a single term].
The problem is that I have multiple vocabularies associated with the node,
and want fine grained control of the output [different vocabularies displayed differently].
My solution above works - in that I get the result I want.
It just feels like there is a might be a more direct way to do it, that I don't know about!
Thanks,
Alan
vocab id
Ah. I see what you mean. If you already know the vocabulary id, this might work..
<?phpforeach ($node->taxonomy as $term) {
if ($term->vid == 3) { // filter terms in vocabulary with ID 3
$countyname = $term->name
}
}
?>
Winner alright!
Great work Dub!
That works really well.
A much smarter way that I had of getting at that data.

Alan
Perfect
foreach ($query as $term) {
$value = $term->field_subscription_expiration_value;
}
It works damn good for me
