sql没有插入数据库

标签： php html mysql

我知道这是一个非常常见的问题，但我只是在寻找帮助来确定我的代码有什么问题。我正在尝试创建我的数据库，以便管理员可以使用表单中的图片创建新的营地。我的网站似乎工作正常，当我测试它时，如果没有填写值，它会给我失败消息，如果没有填写所需的值，则会给我成功消息，但它不会将信息传递给我的数据库。任何帮助将非常感谢！

另外，我为一个非常糟糕的程序员道歉。

相关网站代码：

<section id="SIGNUP" style="text-align: center;" class="main-container">
        <div class="container" style="width:100%;">
      <h2 style="text-align:center; font-size:50px;">Add a New Campsite</h2>
      <form id="newsletter" <form class="signup-form" action="includes/fetch.inc.php" method="POST" enctype="multipart/form-data" style="padding-top:50px; padding-bottom:50px; border-bottom:#e8491d 3px solid; border-top:#e8491d 3px solid;">

            <input type="integer" name="width" style="padding:4px; height:5%; width:25%; text-align:center; font-size:30px;" placeholder="Site Width"><br>
            <label for="fire">Fire Pit: </label><input type="checkbox" name="fire" value="No">

  <input type="submit" name="submit_image" value="Upload Image"/>
 </form>
 <div id="image_preview"></div>
</div>
</section>;

fetch.inc.php / sql代码：

<?php
if(isset($_POST['submit_image'])) {

  require_once("dbh.inc.php");

    $length = mysqli_real_escape_string($conn, $_POST['length']);
    $width = mysqli_real_escape_string($conn, $_POST['width']);
  $price = mysqli_real_escape_string($conn, $_POST['price']);
    //Error Handlers
    //Check for empty fields

    if (empty($length) || empty($width) || empty($price)) {
        header("Location: ../admin.php?null-value");
        exit();
  } else {

//insert image address into images folder and add the address to reservations table

2 个答案:

答案 0 :(得分：3)

如果您修改fire，sewer和electric的字段值，方法是将其更改为默认值为1（一）的整数， php中的逻辑。

insert语句应该使用prepared statements来避免sql注入。

我还强烈建议您使用css来控制表单的外观而不是此处的内联样式 - 它使代码更精简，更易于阅读，更重要的是更容易更改！

以下代码全部在一页上供我测试 - 您需要将html和php分成两个组成页面，就像您最初使用它们一样〜抱歉改变它这么多，但我认为你应该能够让它现在起作用。

关于存储对存储在数据库中的图像的引用的最后一条评论之后，我有一点戏剧 - 也许这可能是有意义的。

毫无疑问，实际的数据库架构要复杂得多，但我很快为演示构建了2个表。

create table `campsites` (
    `id` int(10) unsigned not null auto_increment,
    `length` smallint(5) unsigned not null default '0',
    `width` smallint(5) unsigned not null default '0',
    `fire` bit(1) not null default b'0',
    `sewer` bit(1) not null default b'0',
    `electric` bit(1) not null default b'0',
    `price` decimal(10,0) unsigned not null default '0',
    primary key (`id`)
)
collate='utf8_general_ci'
engine=innodb;

create table `campsite_images` (
    `id` int(10) unsigned not null auto_increment,
    `cid` int(10) unsigned not null default '0',
    `photo` varchar(128) not null default '0',
    primary key (`id`),
    index `cid` (`cid`),
    constraint `fk_cs_img` foreign key (`cid`) references `campsites` (`id`) on update cascade on delete cascade
)
collate='utf8_general_ci'
engine=innodb;

答案 1 :(得分：1)

很难说没有看到所有代码（例如你的@Entity(name = "r_classroom") public class Classroom extends Model { @OneToMany(mappedBy = "classroom", cascade = CascadeType.ALL, orphanRemoval = true) public List<Group> groups = new ArrayList<>(); @ManyToMany(mappedBy = "classrooms", cascade = {CascadeType.PERSIST, CascadeType.MERGE}) public List<Student> students = new ArrayList<>(); public String name; } @Entity(name = "r_student") public class Student extends Model { @ManyToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE}) public List<Classroom> classrooms = new ArrayList<>(); @ManyToMany(cascade = {CascadeType.MERGE, CascadeType.PERSIST}) public List<Group> groups = new ArrayList<>(); public String name; } @Entity(name = "r_group") public class Group extends Model { @ManyToOne public Classroom classroom; @ManyToMany(mappedBy = "groups", cascade = {CascadeType.PERSIST, CascadeType.MERGE}) public List<Student> students = new ArrayList<>(); public String name; } 正在做什么），但我猜测PHP和/或MySQL会抛出错误。

为了使您的代码更加健壮，可以添加检查以确保您的查询正确执行：

require_once("dbh.inc.php");

然后检查您的PHP错误日志，您应该在那里看到结果。

您可以通过查看mysqli_query($conn, $sql); if (!mysqli_query($conn, $sql)) { error_log("SQL query error: " . mysqli_error($conn)); } 和php.ini文件找到错误日志文件。如果您正在使用Linux，则使用常见的默认位置：

mysql.cnf

如果您正在使用运行cPanel之类的托管服务提供商，您应该可以在那里找到对日志文件的访问权限。

您可以将错误打印到屏幕上，以便更容易调试，但出于安全原因，这在生产代码中建议不。一旦您熟悉访问错误日志，您无论如何都不需要这样做，但是为了记录：

/var/log/php_errors.log
/var/log/mysqld.log
