Question

我想我已经做好了一切。这一定是个愚蠢的错误。我已经设置了MySQL连接并使用真正的字符串转义来保护安全。请指出我的错误或建议我是否可以通过其他方式完成？

另外，请建议我如何在我的数据库中检索提交的数据，并将该数据获取到另一个xml文件或电子邮件。

<?php 
//is there a problem in connection? 
$link = mysqli_connect("localhost","root","");
if($link == false){
die("error"); }
if(
isset($_POST['name']) &&
isset($_POST['type']) &&
isset($_POST['email']) &&
isset($_POST['website']) &&
isset($_POST['app']) &&
isset($_POST['phone']) &&
isset($_POST['about']))
{
//real escape string is used, is it affecting my data? 
$name = mysqli_real_escape_string($link, $_POST['name']);
$type = mysqli_real_escape_string($link, $_POST['type']);
$email = mysqli_real_escape_string($link, $_POST['email']);
$website = mysqli_real_escape_string($link, $_POST['website']);
$app = mysqli_real_escape_string($link, $_POST['app']);
$phone = mysqli_real_escape_string($link, $_POST['phone']);
$about = mysqli_real_escape_string($link, $_POST['about']);

//query has been created 
$query = "INSERT INTO `contact_form` (name, type, email, website, app,
phone, about) VALUES ('$name', '$type', '$email', '$website', '$app', '$phone', '$about')";
if(mysqli_query($link, $query)){
    echo 'the form has been submitted successfully';
}else{
    echo 'there was some problem';
}

}   
?>

您必须将mysqli_select_db用于要添加记录的select数据库。

<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

// ...some PHP code for database "my_db"...

// Change database to "test"
mysqli_select_db($con,"test");

// ...some PHP code for database "test"...

mysqli_close($con);
?>

数据未在PHP表中发布在MySQL表中。请告诉我这里我做错了什么
