致命错误:未捕获错误:在C:\ xampp \ htdocs \ MyFirstWebsite \ register.php中调用未定义函数mysql_real_escape_string():19堆栈跟踪:#0 {main}抛出C:\ xampp \ htdocs \ MyFirstWebsite \第19行的register.php
<?php
if($_SERVER["REQUEST_METHOD"] == "POST"){
$username = mysql_real_escape_string($_POST['username']);
$password = mysql_real_escape_string($_POST['password']);
echo "Username entered is : ". $username . "<br/>";
echo "Password entered is : ". $password;
}
?>
第19行的代码如下:
$username = mysql_real_escape_string($_POST['username']);
然后我尝试使用mysqli()。所以我改变了我的PHP代码:
<?php
if($_SERVER["REQUEST_METHOD"] == "POST"){
$username = mysqli_real_escape_string($_POST['username']);
$password = mysqli_real_escape_string($_POST['password']);
echo "Username entered is : ". $username . "<br/>";
echo "Password entered is : ". $password;
}
?>
警告:mysqli_real_escape_string()只需要2个参数,1 在第19行的C:\ xampp \ htdocs \ MyFirstWebsite \ register.php中给出
警告:mysqli_real_escape_string()只需要2个参数,1 在第20行的C:\ xampp \ htdocs \ MyFirstWebsite \ register.php中给出
这里,在第19行和第20行。以下代码在于:
$username = mysqli_real_escape_string($_POST['username']);
$password = mysqli_real_escape_string($_POST['password']);
任何人都可以帮助我并告诉我该代码应该包含哪些内容?
答案 0 :(得分:0)
您必须将连接变量作为第一个参数传递,如下所示:
$username = mysqli_real_escape_string($conn,$_POST['username']);
此处$conn
是
$conn = mysqli_connect('hostname','username','password','dbname');
