Question

我已经创建了一个搜索页面，但无论我如何更改它，即使它们与数据库完美匹配，也无法返回结果。有人可能是另一双眼睛并指出我正确的方向吗？

我总是不确定将变量放在SQL语句中，所以可能是错误。

Searchform.php

<?php
include 'index.php';
?>
<html>
<center>
<link rel="stylesheet" type="text/css" href="skeleton.css" />
<link rel="stylesheet" type="text/css" href="normalize.css" />
 <title>Search</title> 

<h3>Search People</h3> 
<p>You  may search either by first or last name</p> 
<form  method="post" action="search.php"  id="searchform"> 
<input  type="text" name="name"> 
<input  type="submit" name="submit" value="Search"> 
</form>       
</html> 
</p>
</center>

的search.php

<?php 
    include 'pagetemplate.php';
    if(isset($_POST['submit'])){ 
        if(isset($_GET['go'])){ 
            if(preg_match("/[A-Z  | a-z]+/", $_POST['name'])){ 
                $name=$_POST['name']; 
                //-query  the database table 

              $result = $mysqli_conn->query("SELECT * FROM users WHERE FirstName LIKE '%$name%' OR LastName LIKE '%$name%'");
             print " Query returned ". $result->num_rows . " rows ";
             //The function to display data is below
             displayData($result);


                // $stmt = mysqli_prepare($con, 'SELECT * FROM users WHERE (FirstName LIKE ? OR LastName LIKE ? OR Username LIKE ?)';

                //mysqli_stmt_bind_param($stmt, 'sss', "%$name%", "%$name%", "%$name%");

                //mysqli_stmt_execute($stmt);

                //-run  the query against the mysql query function 


                } 
                else{ 
                    echo  "<p>Please enter a search query</p>"; 
                    } 
            } 
        } 
    ?>
