我一直在尝试在我的数据库中插入这些信息，但没有插入任何内容请帮助（顺便说一句，我还是初学者） 我试图插入用户将填写表格在我的数据库中的信息，当我点击提交页面是空白但当我检查我的数据库我的信息没有添加

1 个答案:

答案 0 :(得分：0)

正如已经指出的那样，问题的答案是file uploads are found in $_FILES，但此代码存在大量其他问题。

像这样混合使用PHP和HTML会让人感到麻烦。它使更新和调试变得更加困难。使用alternative syntax和short echo tags可以使这更加无缝。此外，在将其插入HTML之前，您需要escape output。

每次要与数据库通信时，都不需要创建新的数据库对象。这会给您的程序增加一大笔开销。对同一对象执行所有数据库查询。也可以在文件顶部进行操作，以便按上述方法将其分开。

在这种情况下，

isset()将始终返回true，检查它是没有意义的。此外，您必须在将用户输入放入数据库之前将其转义。使用prepared statements执行此操作。

以下是我将如何开始使用此文件：

<?php
$conn=new PDO('mysql:host=localhost;dbname=cars','root','');
$sl = "SELECT distinct Ville from villes";
$std = $conn->query($sl);
$villes = $std->fetchAll(PDO::FETCH_COLUMN,0);
$sl = "SELECT distinct carbrand from car";
$std = $conn->query($sl);
$marques = $std->fetchAll(PDO::FETCH_COLUMN,0);
$sl = "SELECT distinct year from years";
$std = $conn->query($sl);
$annees = $std->fetchAll(PDO::FETCH_COLUMN,0);
$sl = "SELECT distinct km from kms";
$std = $conn->query($sl);
$kms = $std->fetchAll(PDO::FETCH_COLUMN,0);
$sl = "SELECT distinct caro from carosserie";
$std = $conn->query($sl);
$caros = $std->fetchAll(PDO::FETCH_COLUMN,0);
$sl = "SELECT distinct color from colors";
$std = $conn->query($sl);
$couleurs = $std->fetchAll(PDO::FETCH_COLUMN,0);
$sl = "SELECT distinct puiss from pusissance";
$std = $conn->query($sl);
$puissances = $std->fetchAll(PDO::FETCH_COLUMN,0);

if (isset($_POST)) {
    $photo = file_get_contents($_FILES["photo"]["tmp_name"]);
    $sql= "INSERT INTO owner VALUES(:type, :name, :email, :tel, :ville, :categ, :marque, :year, :km, :caros, :carburant, :trans, :cylindre, :puissance, :douane, :desc, :prix, :photo)";
    $stmt = $con->prepare($sql);
    $stmt->execute(array(
        ":type" => $_POST['type'],
        ":name" => $_POST['name'],
        ":email" => $_POST['email'],
