Question

我想创建一个与数据库一起使用的帖子创建者，但我无法上传图片或文件。我的网页正在使用materialize框架。这段代码大多缩小到重要部分。

<?php
require_once 'include/Database.php';
require_once 'include/Sessions.php';
require_once 'include/Functions.php';

if (isset($_POST['addPostButton']) || isset($_FILES['image'])) {

    $imageName = $_POST['image'];
    $imageDirectory = 'uploads/' . basename($_FILES['image']['name']);

    if (!move_uploaded_file($_FILES['image']['tmp_name'], $imageDirectory)) {
        $_SESSION['ErrorMessage'] = 'File is invalid!';
    } else {
        global $ConnectingDB;
        $stmt = $ConnectingDB->prepare("INSERT INTO posts(image) VALUES('$imageName')");
        if ($stmt->execute()) {
            $_SESSION['SuccessMessage'] = 'Post created';
        }
    }
}
?>

Answer 1

这

<form action="add-post.php" method="post">

要

<form action="add-post.php" method="post" enctype="multipart/form-data">

此处需要向已发送文件添加表单属性enctype。

图像/文件上载不适用于materializecss框架
