人们！我试图在我的网站上实现录音机。我想要的是让用户将录制的文件直接保存到数据库和我网站上的子文件夹（称为/ speaking_audios）。主要文件如下：
recorder.php

好吧，我只是想让你专注于upload.php文件，看看我做错了什么。我不知道问题是否是由线路退出引起的;＆＃34;在upload.php文件中。该文件将保存到子文件夹＆＃34; / speaking_audios＆＃34;，但不保存到数据库。为什么？也许问题出在upload.php文件行中：
include "config.php";
$upload_file=$upload_name; # also $upload_name
$username_id = $_SESSION['username'];
$stmt = $pdo->prepare("INSERT INTO `recordings` (username, filename, currenttime) VALUES (:username_id, :upload_file, NOW())");
$stmt->execute(array(':username_id' => $username_id, ':upload_file' => $upload_file));

保存文件后，在recorder.php上传状态后会显示绿色信息。这是当点击箭头保存/上传upload.php开始行动，但没有显示。可以这么说的用户仍然在页面记录器上.php。
答案 0 :(得分：2)
退出后的任何内容都不会被执行！
试着删除它......
在查询后，请尝试添加：
if($stmt->errorCode() == 0) {
echo "success";
} else {
$errors = $stmt->errorInfo();
print_r($errors);
}
可能会给出一些解释。
同样id将我的数据库执行到行之前：
if($_POST['format'] == 'json') {
还注意到所有表字段都设置为NOT NULL，但您只插入3个字段。如果将它们留空，则会导致错误。
您的username_id字段设置为int，我想您可能尝试使用用户名填充它，这可能是varchar
答案 1 :(得分：0)
我知道问题出在哪里。它只是使用：
if(isset($_FILES['upload_file'])){
很简单...解决了问题。
