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;}
