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;}
