我在将数据从我的 php 表单获取到我的 mysql 数据库时遇到问题。我通过准备输入、绑定它们然后执行来使用 mysqli。
提交表单时我没有收到任何错误。如果我故意将错误放入准备语句中，例如拼写错误“INERT INTO table...”然后提交表单，则会显示错误。如果我在 bind_param 中添加了一个额外的字符串或整数值，它不会出错，如果我在 bind_param 中添加了一个额外的变量或拼错了一个变量，它也不会出错。我不能为我的生活弄清楚出了什么问题！我计算了准备值的数量与绑定值和变量的数量，并且计数匹配。
以下是提交表单时正在执行的输入表单：
<?php
//set database connection parameters
$hostname = 'localhost:3307'; // usually is localhost
$db_user = 'test'; // change to your database username
$db_password = 'test'; // change to your database password
$database = 'test'; // provide your database name
//database connection
$db = new mysqli($hostname, $db_user, $db_password, $database);
if(mysqli_connect_errno())
{
printf("Unable to connect to database: %s\n", mysqli_connect_error());
exit();
}
//Prepare prerequisites
$created = date("d-m-Y H:i:s");
$ip = $_SERVER['REMOTE_ADDR'];
