Question

我收到查询错误，我使用类似LIKE sql函数来搜索用户提交的名称。

但msqli_query如果我删除LIKE函数它会发生错误但是不能用LIKE函数

<!DOCTYPE html>
<html>
<head>
<title>Search Users</title>
</head>
<body>
<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>"method="GET">

Name: <input type="text" name="name"></input> 

<input type="submit" name="searchusers" value="Submit"></input> </br>

</body>
</html>

<?php require('connect.php');

$name = @$_GET['name'];


if ($_SERVER["REQUEST_METHOD"] == "GET")
{   
$select123 ="SELECT username FROM users WHERE username LIKE ='%".$name."%'"; 
$check = mysqli_query($conn, $select123) or die("query error");
mysqli_num_rows($check) or die("Couldnt not find the Specified username");

}
?>

请帮忙

Answer 1

删除关键字=附近的like：

$select123 ="SELECT username FROM users WHERE username LIKE '%".$name."%'";

mysqli_query SELECT LIKE函数不起作用
