简单的PHP mongoDB用户名和密码检查站点 [英] Simple PHP mongoDB Username and Password Check for site

问题描述

因此，我有一个名为:'members'的集合，因为我为每个'members'提供了一个用户名和密码. 我需要知道的是如何检查两者是否匹配，即用户名+密码=成功

So, I have a collection called: 'members' and in that I have a user name and password for each of my 'members'. What I need to know is how do I check to see if the two match i.e. username + password = success

这是我尝试过的方法，它可以正确搜索，只是如果没有用户，它不会返回错误

This is what I have tried and it does the search correctly, just it's not returning the error if no user

public function userlogin($data)
    {
        $this->data = $data;
        $collection = $this->db->members;
        // find everything in the collection
        $cursor = $collection->find(array("username"=>$this->data['username'], "password"=>$this->data['password']));

        $test = array();
            // iterate through the results
            while( $cursor->hasNext() ) {
                $test[] = ($cursor->getNext());
            }
        //Print Results 

        if($test == NULL)
        {
            print "Sorry we are not able to find you";
            die;
        }
        //print json_encode($test);

    }   

推荐答案

类似以下内容:

$mongo = new Mongo();
$db = $mongo->dbname;    

$user = $db->collection->findOne(array("username" => $username, "password" => $password));
if ($user->count() > 0)
    return $user;
return null;

或者:

$user = $db->collection->findOne(array("username" => $username, "password" => $password));
$user->limit(1);
if ($user->count(true) > 0)
    return $user;
return null;
