Drupal 6：基於兩個分類術語的PHP打印

Question

我想用php打印某些節點，如果該節點有兩個特定的術語。

是這樣的：

<?php 
    $terms = taxonomy_node_get_terms($node, $key = 'tid'); 
    foreach ($terms as $term) { 
     if ($term->tid == 19) { 
      print '19'; 
     } 
     if ($term->tid == 21) { 
      print '21'; 
     } 
    } 
?> 

Answer 1

taxonomy_node_get_terms()返回與術語ID作爲數組的鍵陣列。所以要做類似你想要的邏輯，你需要類似如下的東西：

$tids = taxonomy_node_get_terms($node); 
// a $node object is passed as the only parameter in this case, so you would need to use node_load to get that 
// the function has an optional second parameter, and 'tid' is the default, so it's not needed 
$tids = array_keys($tids); 
if (in_array(19, $tids)) { 
    print '19'; 
} 
if (in_array(21, $tids)) { 
    print '21'; 
}
