Laravel5中实现模糊匹配加多条件查询功能的方法

本文实例讲述了Laravel5中实现模糊匹配加多条件查询功能的方法。分享给大家供大家参考，具体如下：

方法1. ORM模式

public function ReportAccurate($data)
{
 if(is_array($data))
 {
   $where = $this->whereAll($data);
   return $where;
 }
 else
 {
   return false;
 }
}
/*多条件模糊*/
public function whereAll($data)
{
  $query = new ReportMainpage();
  $results = $query->where(function ($query) use ($data) {
    $data[\'report_first_received_date\'] && $query->where(\'report_first_received_date\', \'like\', \'%\' . $data[\'report_first_received_date\'] . \'%\');
    $data[\'report_drug_safety_date\'] && $query->where(\'report_drug_safety_date\', \'like\', \'%\' . $data[\'report_drug_safety_date\'] . \'%\');
    $data[\'aecountry_id\'] && $query->where(\'aecountry_id\', $data[\'aecountry_id\']);
    $data[\'received_fromid_id\'] && $query->where(\'received_fromid_id\', $data[\'received_fromid_id\']);
    $data[\'research_id\'] && $query->where(\'research_id\', \'like\', \'%\' . $data[\'research_id\'] . \'%\');
    $data[\'center_number\'] && $query->where(\'center_number\', \'like\', \'%\' . $data[\'center_number\'] . \'%\');
  })->get();
  return $results;
}

上面的$data为前端传过来的数组 利用封装拼接进行模糊或者精确的多条件搜素

不好的地方 代码不健壮 不利于维护

方法2. 大神封装法 利用到的知识是Repository 仓库

$fields = [\'id\', \'report_id\', \'report_identify\', \'report_first_received_date\', \'drug_name\', \'first_event_term\', \'case_serious\', \'standard_of_seriousness\', \'case_causality\', \'received_from_id\', \'task_user_name\', \'organize_role_name\', \'task_countdown\', \'report_countdown\'];
/*查询的字段*/
$searchFields = [
  \'report_identify\' => \'like\',
  \'drug_name\' => \'like\',
  \'event_term\' => \'like\',
  \'organize_role_id\' => \'=\',
  \'case_causality\' => \'=\',
  \'report_type\' => \'=\',
  \'task_user_id\' => \'=\',
  \'status\' => \'=\',
];
/*获取查询条件*/
$where = $this->searchArray($searchFields);
/*获取数据*/
$this->reportTaskRepo->pushCriteria(new OrderBySortCriteria(\'asc\', \'task_countdown\'));
$data = $this->reportTaskRepo->findWhere($where, $fields);
//在Trait里封装
/**
 * 获取请求中的参数的值
 * @param array $fields [description]
 * @return [type]     [description]
 */
public function searchArray($fields=[])
{
  $results = [];
  if (is_array($fields)) {
   foreach($fields as $field => $operator) {
     if(request()->has($field) && $value = $this->checkParam($field, \'\', false)) {
      $results[$field] = [$field, $operator, \"%{$value}%\"];
     }
   }
  }
  return $results;
}
