如何獲得有條件的關系場

Question

當我們想獲得一些關系字段時，我們會做

$pod = pods( 'pod_name', get_the_id() );
$related = $pod->field( 'relationship_field' );

並且我得到結果數組1、2 ...的列表，但是我需要獲得relationship_field其中name="some_name" 。 我怎樣才能做到這一點？

Answer 1

如果相關帖子的標題等於some_name ，則以下內容將檢索名為relationship_field的相關字段：

$pod = pods('pod_name', get_the_ID());
$params = array(
  'WHERE' => "relationship_field.post_title = 'some_name'",
);

$related = $pod->find($params);

Answer 2

您的示例是正確的，但稍作調整后，此示例將更加有用：

// get the pod record based on current post ID
$pod = pods( 'pod_name', get_the_ID() );

$params = array(
    // be sure to sanitize the value going in, if it's dynamic
    'where' => 'relationship_field.post_title = "Some title"'
);

// find records that match $params
$pod->find( $params );

// loop through records found
while ( $pod->fetch() ) {
    // do something with $pod->field( 'field_name' )
    // or $pod->display( 'field_name' )
}
