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;

}
