php - 如何获取具有条件的关系字段

Question

当我们想要获得一些关系字段时，我们会这样做

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

我得到了结果数组 1、2 的列表……但我需要得到relationship_fieldwhere name="some_name"。我怎样才能做到这一点？

Answer 1

relationship_field如果相关帖子的标题等于 ，则以下将检索命名的相关字段some_name：

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

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

Answer 2

你的例子是对的，但稍作调整，这将作为一个例子更有用：

// 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' )
}
