我正在工作的小页面，我通过PHP页面更新MySQL记录，所有的功能都很好地工作，但我不断得到一个未定义的数组警告。以下是警告：

Warning: Undefined array key "file" in C:\xampp\htdocs\crud\edit.php on line 11
Warning: Trying to access array offset on value of type null in C:\xampp\htdocs\crud\edit.php on line 11
Warning: Undefined array key "file" in C:\xampp\htdocs\crud\edit.php on line 22
Warning: Trying to access array offset on value of type null in C:\xampp\htdocs\crud\edit.php on line 22

我看了很多这样的主题，但没有设法修复我自己的一个...以下是edit.php的代码

include 'db.php';

// File upload path
$targetDir = "uploads/";
$fileName = basename($_FILES["file"]["name"]);
$targetFilePath = $targetDir . $fileName;
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);

if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){
}
    // Allow certain file formats
    $allowTypes = array('jpg','png','jpeg','gif','pdf','doc','xlsx');
    if(in_array($fileType, $allowTypes)){
    }
        // Upload file to server
        if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){
        }

我也有一个pcs的HTML，在〈形式：

<form name="update_user" method="post" action="edit.php" enctype="multipart/form-data" >
<tr>
                <td>Нов сертификат:</td>
                <td><input type="file" name="file" ></td>
</tr>

我觉得我错过了一些很简单的事情。
-----更新-------这里是我的完整代码：在一个文件中我把php和html放在一起

// include database connection file
include_once("config.php");
//тук стартирам за фаил ъплоад
// Include the database configuration file
include 'db.php';

// File upload path
$targetDir = "uploads/";
$fileName = basename($_FILES["file"]["name"]);
$targetFilePath = $targetDir . $fileName;
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);

if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){
}
    // Allow certain file formats
    $allowTypes = array('jpg','png','jpeg','gif','pdf','doc','xlsx');
    if(in_array($fileType, $allowTypes)){
    }
        // Upload file to server
        if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){
        }
// край на фаил ъплоад

// Check if form is submitted for user update, then redirect to homepage after update
if(isset($_POST['update']))
{
    $id = $_POST['id'];
    $toolnr=$_POST['toolnr'];
    $status=$_POST['status'];
    $toolname=$_POST['toolname'];
    $serial=$_POST['serial'];

    $owner=$_POST['owner'];
    $calibrated=$_POST['calibrated'];
    $nextcalibration=$_POST['nextcalibration'];
    $vendors=$_POST['vendors'];
    
    // update user data
    $result = mysqli_query($mysqli, "UPDATE tools SET toolnr='$toolnr',status='$status',toolname='$toolname',serial='$serial',usedat='$usedat',owner='$owner',calibrated='$calibrated',nextcalibration='$nextcalibration', vendors='$vendors', file_name = '$fileName' WHERE id='$id'");
    // Redirect to homepage to display updated user in list
    header("Location: index.php");
}

?>
<?php
// Display selected user data based on id
// Getting id from url
$id = $_GET['id'];
// Fetech user data based on id
$result = mysqli_query($mysqli, "SELECT * FROM tools WHERE id=$id");
while($user_data = mysqli_fetch_array($result))
{
    $toolnr = $user_data['toolnr'];
    $status = $user_data['status'];
    $toolname = $user_data['toolname'];
    $serial = $user_data['serial'];
    $usedat = $user_data['usedat'];

    $nextcalibration = $user_data['nextcalibration'];
    $vendors = $user_data['vendors'];
    $momenten = $user_data['file_name'];
}

过账工作代码：最终修复的代码（只有php部分）。问题是负责文件上传的代码部分超出了if statement

<?php

// include database connection file
include_once("config.php");

// Check if form is submitted for user update, then redirect to homepage after update
if(isset($_POST['update']))
{

    $id = $_POST['id'];
    $toolnr=$_POST['toolnr'];
    $status=$_POST['status'];
    $toolname=$_POST['toolname'];
    $serial=$_POST['serial'];
    $usedat=$_POST['usedat'];
    $owner=$_POST['owner'];
    $calibrated=$_POST['calibrated'];
    $nextcalibration=$_POST['nextcalibration'];
    $vendors=$_POST['vendors'];
    
// Include the database configuration file
include 'db.php';
$statusMsg = '';

// File upload path
$targetDir = "uploads/";
$fileName = basename($_FILES["file"]["name"]);
$targetFilePath = $targetDir . $fileName;
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);

if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){

    // Allow certain file formats
    $allowTypes = array('jpg','png','jpeg','gif','pdf','doc','xlsx');
    if(in_array($fileType, $allowTypes)){
    }
    }
        // Upload file to server
        if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){
        }

    // update user data
    $result = mysqli_query($mysqli, "UPDATE tools SET toolnr='$toolnr',status='$status',toolname='$toolname',serial='$serial',usedat='$usedat',owner='$owner',calibrated='$calibrated',nextcalibration='$nextcalibration', vendors='$vendors', file_name = '$fileName' WHERE id='$id'");
    // Redirect to homepage to display updated user in list
    header("Location: index.php");
}

?>
