Question

我不确定是不是因为我真的很累或什么;我似乎无法弄清楚为什么我不能使用此代码插入我的数据库。

<?php
require 'mysqlcon.php';
?>

<?php


if(isset($_POST["submit"])){
try {
$dbh = new PDO("mysql:host=$hostname;dbname=CSY2028",$username,$password);

$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // <== add this line
$sql = "INSERT INTO bookings (name, email)
VALUES ('".$_POST["name"]."','".$_POST["email"]."')";
if ($dbh->query($sql)) {
header("location: index.php");
echo "<script type= 'text/javascript'>alert('New Record Inserted Successfully');</script>";

}
else{
echo "<script type= 'text/javascript'>alert('Data not successfully Inserted.');</script>";
}

$dbh = null;
}
catch(PDOException $e)
{
echo $e->getMessage();
}

}
?>

我有下表我已经检查过ID，名字都是一样的＆amp;匹配。它只是没有插入任何东西？

<?php
require 'mysqlcon.php';

Answer 1

未命名提交

<input type="submit" value="Book Vehicle" class="special" />

if(isset($_POST["submit"])){...}内的任何内容都不会启动。

所以：

<input name="submit" type="submit" value="Book Vehicle" class="special" />

另外，由于您正在使用PDO，请使用预准备语句。您可以使用SQL注入。
