EntityFieldQuery多個替代條件

Question

是否有更優化和更短的方式來獲得具有特定條件的節點？

$query = new EntityFieldQuery; 
$result = $query 
    ->entityCondition('entity_type', 'node') 
    ->propertyCondition('type', $node_type) 
    ->propertyCondition('title', $title) 
    ->fieldCondition('field_number', 'value', '1', '='); 
    ->propertyCondition('status', 1, '=') 
    ->execute(); 

// $result['node'] contains a list of nids where the title matches 
if (!empty($result['node']) { 
    // You could use node_load_multiple() instead of entity_load() for nodes 
    $nodes = entity_load('node', array_keys($result['node'])); 
} 

$query_two = new EntityFieldQuery; 
$result_two = $query_two 
    ->entityCondition('entity_type', 'node') 
    ->propertyCondition('type', $node_type) 
    ->propertyCondition('title', $title) 
    ->fieldCondition('field_number', 'value', '2', '='); 
    ->propertyCondition('status', 1, '=') 
    ->execute(); 

// $result_two['node'] contains a list of nids where the title matches 
if (!empty($result_two['node']) { 
    // You could use node_load_multiple() instead of entity_load() for nodes 
    $nodes_two = entity_load('node', array_keys($result_two['node'])); 
} 

Answer 1

嗯，你當然可以使用->fieldCondition('field_number', 'value', array(1, 2))，但除此之外，不，我知道的（我寫EntityFieldQuery）。即使你將這個改寫成只存儲SQL存儲的查詢，也不會太簡單。

您不需要指定=作爲運算符，也不需要指定IN，它們是標量/數組值的默認值。

Answer 2

我最近爲EntityFieldQuery編寫了一個包裝，因爲我只是使用它太多。然後我調用它的方式變爲，結果可以是id或id數組。希望這是有道理的。

$ids = qplot_api_find_nodes2(
    array(
     'type' => 'content', 
     'field_content_project' => array('target_id', 10, '='), 
    ), 
    array(
     'created' => 'ASC' 
    ), 
    TRUE 
); 

/** 
* Returns node nid(s) with filters and sorts. 
* 
* @param array $conds 
* Condition entries, there're three different type of conditions 
* 1. prefixed with entity_, ex. 'entity_type' => 'node' 
* 2. prefixed with field_, ex. 'field_project', 
*  two formats allowed, simple version 'field_tag' => 'abc', 
*  or long version, 'field_tag' => array('target_id', 11, '=') 
* 3. no prefix or other prefix, 'title' => 'abc' 
* Default $conds contains 'entity_type' => 'node' entry. 
* 
* @param array $sorts 
* Sort entiries, there're two different type of sorts 
* 1. prefixed with field_, ex. 'field_tag' => array('target_id', 'ASC') 
* 2. no prefix or other prefix, 'title' => 'ASC' 
* Default $sorts are empty 
* 
* @param bool $all 
* If all matching nid are returned, or just the first one, default FALSE 
* 
* @return int 
* The nid for the supplied id or 0 if not found. 
* Or array of nids if $all = TRUE
