Question

基本上我是用php和MySQL从头开始创建一个社交网络CMS

我需要搜索工作，搜索用户的用户名，显示名称和电子邮件，以返回上述任何结果

<?php require('core.common.php');
//Search page php
$sq    = htmlspecialchars($_GET['q'], ENT_QUOTES);

$search = $db->prepare("SELECT username, disp_name, profilepic 
FROM users WHERE username OR disp_name OR email LIKE '%sq%';"); 
$search->execute();
$viewsearch = $search->fetchAll();

我已经尝试了这个，但一次只能在一列上运行：

$search = $db->prepare("SELECT username, disp_name, profilepic
    FROM users WHERE username LIKE '%$sq%';");

我已经尝试过了......

"SELECT username, disp_name, profilepic FROM users WHERE username LIKE '%sq%'OR disp_name LIKE '%sq%'OR email LIKE '%sq%' ORDER BY username;"

和

"SELECT username, disp_name, profilepic FROM users WHERE ((username LIKE '%sq%') OR (disp_name LIKE '%sq%') OR (email LIKE '%sq%'));"

除了以上几种变体之外，仍然没有希望。

Answer 1

SELECT username, disp_name, profilepic 
FROM users 
WHERE username LIKE '%sq%'
OR disp_name LIKE '%sq%'
OR email LIKE '%sq%'

Answer 2

我认为您正在寻找的是：

SELECT username, disp_name, profilepic 
FROM users 
WHERE username LIKE '%sq%'
    OR disp_name LIKE '%sq%'
    OR email LIKE '%sq%';

MySQL WHERE多列LIKE＆＃39;％$ sq％＆＃39;返回空数组
