Question

在@Fky＆amp ;;的大力帮助下尤其是@Syscall我设法将drupal查询更改为在3个表而不是2个表中进行搜索，并添加条件以及关键字拆分和删除空格。

drupal sql conditional clauses for multiple tables?

我希望结果1）按关键字匹配结果排序，然后按照ASC中的标题排序。

IE中。寻找“香蕉苹果橙”返回：

香蕉橙
苹果
香蕉
橙

我设法按标题排序，但无法弄清楚如何按关键字出现次数排序？

$term = strip_tags(drupal_substr($_POST['keyword'], 0, 100));
$terms = explode(' ', $term); // split using ' '
$terms = array_map('trim', $terms); // remove unwanted spaces
$termsfiltered = array_filter($terms);
 $or = db_or();
  foreach ($termsfiltered as $term) {
    $or->condition('fd.field_detailed_question_value', '%'.db_like($term).'%', 'LIKE');
    $or->condition('fb.body_value','%'.db_like($term).'%' , 'LIKE');
    $or->condition('n.title','%'.db_like($term).'%' , 'LIKE');
    }
 $query = db_select('node', 'n');

$query->fields('n');
$query->range(0,20); //LIMIT to 15 records
$query->orderBy('title', 'ASC'); //ORDER BY title
$query->leftJoin('field_data_body' , 'fb', 'fb.entity_id=n.nid');
$query->leftJoin('field_data_field_detailed_question' ,'fd', 'fd.entity_id=n.nid');
$query->condition($or);
$query->condition('n.status','1');
$stmt = $query->execute(); // execute the query (returns the "statement" to fetch).

我发现了一个提及

的问题Sort sql result by occurence of a set of keywords

带上你的where子句，将所有或替换为+，并确保每个像声明一样的个体用括号括起来，然后按它排序。

我还看到了使用 $ query-＆gt; addExpression ...

的示例

这是正确的方法/如何使用drupal查询吗？请帮助：）

更新：或以某种方式将orderby与COUNT 组合在一起？

Answer 1

链接的答案认为是正确的方法。

为Drupal查询创建ORDER BY语句可以这样做：

$term = strip_tags(drupal_substr($_POST['keyword'], 0, 100));
$terms = explode(' ', $term); // split using ' '
$terms = array_map('trim', $terms); // remove unwanted spaces
$termsfiltered = array_filter($terms);

$order_array = [] ; // Create an empty array to create the string
$or = db_or() ;
foreach ($termsfiltered as $term) {

    // Or condition
    $or->condition('fd.field_detailed_question_value', '%'.db_like($term).'%', 'LIKE');
    $or->condition('fb.body_value','%'.db_like($term).'%' , 'LIKE');
    $or->condition('n.title','%'.db_like($term).'%' , 'LIKE');

    // Order by array (add the concat of each fields)
    $order_array[] = '(concat(title, fd.field_detailed_question_value, fb.body_value) like \'%'.db_like($term).'%\')';
}

$query = db_select('node', 'n');
$query->fields('n');
$query->range(0,20);
$query->orderBy(implode('+',$order_array), 'desc'); // Dynamic order by
$query->leftJoin('field_data_body' , 'fb', 'fb.entity_id=n.nid');
$query->leftJoin('field_data_field_detailed_question' ,'fd', 'fd.entity_id=n.nid');
$query->condition($or);
$query->condition('n.status','1');
$stmt = $query->execute(); // execute the query (returns the "statement" to fetch).

增加的是：

$order_array = [] ;
$order_array[] = '(concat...)
$query->orderBy(implode('+',$order_array), 'desc');已更改

请注意，您可以通过使用（或类似的东西）来防止错误：

if (empty($termsfiltered)) { return "No matches."; }

另一件事。使用$_POST在Drupal中不是一个好习惯。如果您来自表单，则应使用$form_state['values']['keyword']代替$_POST['keyword']：请参阅this example。

修改

$term = strip_tags(drupal_substr($_POST['keyword'], 0, 100)); $terms = explode(' ', $term); // split using ' ' $terms = array_map('trim', $terms); // remove unwanted spaces $termsfiltered = array_filter($terms); $order_array = ['title'=>[],'question'=>[],'body'=>[]] ; // Create an empty array to create the string $or = db_or() ; foreach ($termsfiltered as $term) { // Or condition $or->condition('fd.field_detailed_question_value', '%'.db_like($term).'%', 'LIKE'); $or->condition('fb.body_value','%'.db_like($term).'%' , 'LIKE'); $or->condition('n.title','%'.db_like($term).'%' , 'LIKE'); // Order by array (add the concat of each fields) $order_array['title'][] = '(title like \'%'.db_like($term).'%\')'; $order_array['question'][] = '(fd.field_detailed_question_value like \'%'.db_like($term).'%\')'; $order_array['body'][] = '(fb.body_value like \'%'.db_like($term).'%\')'; } $query = db_select('node', 'n'); $query->fields('n'); $query->range(0,20); $query->orderBy(implode('+',$order_array['title']), 'desc'); // Dynamic order by $query->orderBy(implode('+',$order_array['question']), 'desc'); // Dynamic order by $query->orderBy(implode('+',$order_array['body']), 'desc'); // Dynamic order by $query->leftJoin('field_data_body' , 'fb', 'fb.entity_id=n.nid'); $query->leftJoin('field_data_field_detailed_question' ,'fd', 'fd.entity_id=n.nid'); $query->condition($or); $query->condition('n.status','1'); $stmt = $query->execute();

drupal查询按匹配结果中的关键字排序排序
