Answer 1

I）更改

将$username = $_POST["username"];更改为$username = $_POST["name"];
在method="POST"

<form>

使用mysqli prepared statement来避免安全漏洞。

II）更新了代码

<强> dbconnect.php

<?php
$host= "host";
$user = "user";
$password = "pass";
$db = "db";

$con = new mysqli($host, $user, $password, $db);
if ($con->connect_errno) {
  echo "Failed to connect to MySQL: (" . $con->connect_errno . ") " . $con->connect_error;
}
?>

<强> addInfo.php

<?php
require "dbconnect.php";

$stmt = $mysqli->prepare("INSERT INTO userInfo (`username`,`email`,`mobile`) VALUES (?, ?, ?)");
$stmt->bind_param('sss', $_POST["name"], $_POST["email"], $_POST["mobile"]);

if($stmt->execute()) {
  echo "Data inserted successfully!";
} else {
  echo "Error in insertion" . $con->errno;
}
?>

<强>的index.php

<!DOCTYPE html>
<html>
  <head>
    <title>Add Information</title>
  </head>
  <body>
    <form action="addinfo.php" method="POST">
      <table>
        <tr>
          <td>Name:</td>
          <td><input type="text" name="name"/></td>
          <td>Email:</td>
          <td><input type="text" name="email"/></td>
          <td>Mobile:</td>
          <td><input type="text" name="mobile"/></td>
        </tr>
      </table>
      <input type ="submit" value="Submit" />
    </form>
  </body>
</html>
