搜索全名，而不只是名字或姓氏 [英] Search with full name instead of just first name or last name

问题描述

我正在开发使用PHP和Codeigniter构建的API，并将MySQL用作数据库。

I am developing an API built with PHP and Codeigniter and I use MySQL as database.

我有一个名为Users的用户表，其中包含以下几列：

I have a user table called Users which contains the following columns:

- ID
- Firstname
- Lastname
- Email

用户如何使用全名搜索此表？例如，按Martin或Smith进行搜索都可以，但不能按Martin Smith进行搜索。

How can a user search this table using a full name? For example it works fine to search either by Martin or Smith, but not Martin Smith.

这是我现在正在使用的查询：

This is the query I am using now:

$this->db->select('*');
$this->db->from('users');
$this->db->like('firstname', $args['query']);
$this->db->or_like('lastname', $args['query']);

更新

如果按照以下建议使用此查询，我什么也找不到。不能使用全名，名字或姓氏。然后，名字和姓氏都必须是相同的单词。

If I use this query as suggested below I cannot find anything. Not with full name, first name or last name. Then both first name AND last name needs to be the same word.

$this->db->select('*');
$this->db->from('users');
$this->db->like('firstname', $args['query']);
$this->db->like('lastname', $args['query']);

推荐答案

直奔我的脑袋，但是那怎么办

Straight out of my head, but what about

$input = 'Martin Smith';

$names = explode($input);

$this->db->select('*'); 
$this->db->from('users'); 
$this->db->where_in('firstname', $names); 
$this->db->or_where_in('lastname', $names);

应输出以下内容：

SELECT * FROM users 
WHERE firstname IN ('Martin', 'Smith') 
OR lastname IN ('Martin', 'Smith')
