我想将用户输入的pdf文件上传到我的mysql数据库中。我提供的代码显示了带有pdf上载输入类型的用户注册表。我想通过AJAX将其发布到我的PHP脚本中，以输入到数据库中。我无法使此代码正常工作。任何建议，将不胜感激？

表单输入的摘要-

    <form id='form1'>
               <label>Are you a:</label>
                    <select name="type" id="type">

<?php

form

尝试使用此代码进行文件存储和插入

<!DOCTYPE html>
<html>
<head>
    <title>test</title>
</head>
<body>
    <form id="form">
        <label for="file">Curriculum Vitae <i>(PDF only)</i></label>
        <input type="file" name="file" id="cv" value="cv" accept=".pdf"><br>

        <label for="file">Garda Vetting <i>(PDF only)</i></label>
        <input type="file" name="gardavetting" id="gardavetting" value="gardavetting" accept=".pdf"><br>

        <label>LinkedIn URL <i>(optional)</i></label>
        <input type="text" id="linkedin" name="linkedin"> <br>

        <button type="submit" id="submit1" name="submit1">Submit</button><br>
    </form>
</body>

    $('#form').on('submit', function(e) {

        var form=document.getElementById('form');

        $.ajax({

            { 
                if(result == 0)
                {
                    alert('file stored');
                }else{

                }

insert.php 

<?php

$dbname = "your db name";

// Create connection

$type2 = $_POST['type'];

// STORE PDF FILE IN FOLDER
if(isset($_FILES['file']['name']))

    move_uploaded_file($_FILES["file"]["tmp_name"], $cpath.$file_path);
    $cv2 = $file_path;
}

$sql = "INSERT INTO users (type, userNo, name, level, phoneNo,

if($sql){
    echo '0';
}

mysqli_query($conn, $sql);

?>

如果存储任何文件（例如（图像，pdf，视频）），请使用表格序列化方法或表格数据方法来避免错误。在这里，我给出了一个代码，用于将pdf文件存储在本地文件夹中，并使用AJAX插入mysql数据库中，而无需刷新页面即可得到结果。
