connection.php

     <?php
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$db = "copy";

$conn = mysql_connect($dbhost,$dbuser,$dbpass);
mysql_select_db($db);
      ?>

submit.php
   <?php
include 'connection.php';

$food1 = $_POST['food1'];
$food2 = $_POST['food2'];
$food3 = $_POST['food3'];
$food4 = $_POST['food4'];
$food5 = $_POST['food5'];


if(!$_POST['submit']) {
    echo "please fill out the form";
    header('Location: select.html');
 } else {
         $sql = "INSERT INTO remove(food1, food2, food3, food4, food5) VALUES ('".$food1."', '".$food2."', '".$food3."','".$food4."','".$food5."');";
         mysql_query($link, $sql);
    echo "User has been added!";
    header('Location: select.html');

     }
     ?>

Answer 1

让您的INSERT INTO声明成为以下形式：

$sql = "INSERT INTO remove(food1, food2, food3, food4, food5) VALUES ($food1, $food2, $food3, $food4, $food5)";

Answer 2

您的行为有误，应为submit.php

另外请不要使用mysql_*函数，因为它们已被弃用。

改为使用mysqli或PDO。还可以使用prepared statements来阻止SQL注入。

connection.php 的示例：

<?php
    $dbhost = "localhost";
    $dbuser = "root";
    $dbpass = "";
    $db = "copy";
    $conn = mysqli_connect($dbhost,$dbuser,$dbpass,$db);
?>

submit.php 的示例（带有预备声明）：

<?php
include 'connection.php';

$food1 = $_POST['food1'];
$food2 = $_POST['food2'];
$food3 = $_POST['food3'];
$food4 = $_POST['food4'];
$food5 = $_POST['food5'];


if(!$_POST['submit']) {
    echo "please fill out the form";
    header('Location: select.html');
 } else {
         $sql = "INSERT INTO remove(food1, food2, food3, food4, food5) VALUES (?,?,?,?,?);";
         $stmt = mysqli_prepare($conn, $sql);
         mysqli_stmt_bind_param($stmt,"sssss",$food1,$food2,$food3,$food4,$food5);
         mysqli_stmt_execute($stmt);
         echo "User has been added!";
         header('Location: select.html');

     }
?>
