尝试从 php FORM 上传到 MYSQL 数据库时出错

Question

我在网页上工作，我需要将我的 MySql dtatabse 与 php 连接起来，我设法做到了，但我无法将数据从网页上传到数据库，我明白了错误

Notice: Undefined index: Naziv in C:\xampp\htdocs\HlodInfo\Skripte\upload.php on line 15

Notice: Undefined index: Naslov in C:\xampp\htdocs\HlodInfo\Skripte\upload.php on line 16

Notice: Undefined index: Vrsta_lesa in C:\xampp\htdocs\HlodInfo\Skripte\upload.php on line 17

Notice: Undefined index: Kontakt in C:\xampp\htdocs\HlodInfo\Skripte\upload.php on line 18

Notice: Undefined index: Ocena in C:\xampp\htdocs\HlodInfo\Skripte\upload.php on line 19

我的代码： (admin.html) 表格：

  <form action="Skripte/upload.php" method="post" enctype="multipart/form-data">
       Naziv: <input type="text" name="Naziv">::
       Naslov <input type="text" name="Naslov">:: <br>
       Vrsta Lesa: <input type="text" name="Vrsta_lesa">::
       Kontakt <input type="text" name="Kontakt">::
       Ocena <input type="text" name="Ocena"> <br>

        <input type="submit" value="OK">
  </form>

PHP代码(upload.php)

<?php



     $dbLink = new mysqli('localhost', 'root', '', 'hlodinfo');
        if(mysqli_connect_errno()) 
            die("MySQL connection failed: ". mysqli_connect_error());



        // Gather all required data
        $naziv = $dbLink->real_escape_string($_FILES['Naziv']['text']);
        $naslov = $dbLink->real_escape_string($_FILES['Naslov']['text']);
        $vrsta_lesa = $dbLink->real_escape_string($_FILES['Vrsta_lesa']['text']);
        $kontakt = $dbLink->real_escape_string($_FILES['Kontakt']['text']);
        $ocena = $dbLink->real_escape_string($_FILES['Ocena']['text']);


         // Create the SQL query
         $query = "INSERT INTO `odkupnik` ( `Naziv`, `Naslov`, `Vrsta_lesa`, `Kontakt`, `Ocena` )


                   VALUES ('{$naziv}', '{$naslov}', {$vrsta_lesa}, '{$kontakt}','{$ocena}')";


         $result = $dbLink->query($query);


         // Close the mysql connection
           $dbLink->close();


?>

我还在学习 PHP 和 javascript，我是初学者。感谢您的帮助，谢谢。

编辑

您到处都在使用 $_FILES...应该是 $_POST

        $naziv = $dbLink->real_escape_string($_POST['Naziv']);
        $naslov = $dbLink->real_escape_string($_POST['Naslov']);
        $vrsta_lesa = $dbLink->real_escape_string($_POST['Vrsta_lesa']);
        $kontakt = $dbLink->real_escape_string($_POST['Kontakt']);
        $ocena = $dbLink->real_escape_string($_POST['Ocena']);

将你的 mysql insert code 放在下面给定的 if 条件

if(isset($_POST['Naziv']) && $_POST['Naziv']!='')
{
  //put your whole database code here...
}

Answer 2

您必须进行如下更改，因为您的表单 http 方法是 POST

    // Gather all required data
    $naziv = $dbLink->real_escape_string($_POST['Naziv']);
    $naslov = $dbLink->real_escape_string($_POST['Naslov']);
    $vrsta_lesa = $dbLink->real_escape_string($_POST['Vrsta_lesa']);
    $kontakt = $dbLink->real_escape_string($_POST['Kontakt']);
    $ocena = $dbLink->real_escape_string($_POST['Ocena']);
