Laravel5实现模糊匹配功能

本文主要和大家介绍了Laravel5中实现模糊匹配加多条件查询功能的方法,结合实例形式分析了Laravel5多条件模糊查询及相关封装操作技巧,希望能帮助到大家。

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;
}
