我正在尝试使用mysqli将表单中的数据插入数据库。但是我没有让它工作:/
这是我填写表单后您所访问的页面中的代码。表单不是问题,因为变量$ headin $ author和$ thecontent都包含数据。并且在实际代码数据库中,用户名密码和名称具有实际值:)
<html>
<head>
<title>Send!</title>
</head>
<body>
<?php
ini_set('display_errors', 1); error_reporting(E_ALL);
$DB_HOST = 'localhost';
$DB_USER = '**';
$DB_PASS = '***';
$DB_NAME = '***';
@ $db = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
if (mysqli_connect_errno()) {
echo 'Error.';
exit();
}
$author = $_POST['author'];
$heading = $_POST['heading'];
$thecontent = $_POST['thecontent'];
$query = 'INSERT INTO articles ('heading', 'author', 'content')
VALUES ('$heading','$author','$thecontent')';
$result = $db->query($query);
if ($result) {
echo $db->affected_rows."This was added.";
}
else {
echo "somethings gone very wrong.";
}
$db->close();
?>
</body>
</html>
答案 0 :(得分:1)
您无法在行名称上添加单引号'
,并且必须为INSERT添加双引号:
$query = "INSERT INTO articles (`heading`, `author`, `content`)
VALUES ('$heading','$author','$thecontent')";
也逃避你的字符串:
$author = $db->real_escape_string($_POST['author']);
$heading = $db->real_escape_string($_POST['heading']);
$thecontent = $db->real_escape_string($_POST['thecontent']);
