人！我正在嘗試在我的網站中實現一臺錄音機。我想要的是讓用戶將錄製的文件直接保存到數據庫和我網站中的子文件夾（稱爲/ speaking_audios）。下面是對主要文件：如何使用pdo上傳錄製的音頻文件到數據庫
recorder.php

數據庫表 「記錄」 SQL結構：
CREATE TABLE `recordings` (
`id` int(5) NOT NULL AUTO_INCREMENT,
`username_id` int(5) NOT NULL,
`username` varchar(50) NOT NULL,
`upload_file` longblob NOT NULL,
`filename` varchar(100) NOT NULL,
`currenttime` datetime NOT NULL,
`type` longtext NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
的config.php
<?php
try {
$pdo = new PDO('mysql:host=localhost;dbname=database','root','');
$pdo->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
echo 'Error: '.$e->getMessage();
}
?>
upload.php的
<?php
$save_folder = dirname(__FILE__) . "/speaking_audios";
if(! file_exists($save_folder)) {
if(! mkdir($save_folder)) {
die("failed to create save folder $save_folder");
}
}
function valid_wav_file($file) {
$handle = fopen($file, 'r');
$header = fread($handle, 4);
list($chunk_size) = array_values(unpack('V', fread($handle, 4)));
$format = fread($handle, 4);
fclose($handle);
return $header == 'RIFF' && $format == 'WAVE' && $chunk_size == (filesize($file) - 8);
}
$key = 'filename';
$tmp_name = $_FILES["upload_file"]["tmp_name"][$key];
$upload_name = md5(uniqid() .rand()). ".wav";
#$_FILES["upload_file"]["name"][$key];
$type = $_FILES["upload_file"]["type"][$key];
$filename = "$save_folder/$upload_name";
#$filename = "$save_folder/$upload_name";
$saved = 0;
if($type == 'audio/wav' && preg_match('/^[a-zA-Z0-9_\-]+\.wav$/', $upload_name) && valid_wav_file($tmp_name)) {
$saved = move_uploaded_file($tmp_name, $filename) ? 1 : 0;
}
if($_POST['format'] == 'json') {
header('Content-type: application/json');
print "{\"saved\": $saved}";
} else {
print $saved ? "Saved" : 'Not saved';
}
exit;
# Save a few info to database
include "config.php";
$username = $_SESSION['username'];
$stmt = $pdo->prepare("INSERT INTO `recordings` (username, filename, currenttime) VALUES (:username, :filename, NOW())");
$stmt->execute(array(':username' => $username, ':filename' => $upload_name));
?>
嗯，我只是想讓你專注於upload.php文件，看看我做錯了什麼。我不知道問題是否由「退出」行引起的？在upload.php文件中。該文件被保存到子文件夾「/ speaking_audios」，但不保存到數據庫。爲什麼？也許問題是在upload.php的文件行：
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));
還有JavaScript中的主音頻控制器：
的js/main.js
$(function() {
var $uploadStatus = $('#upload_status'),
$showLevelButton = $('.show_level'),
$hideLevelButton = $('.hide_level'),
$level = $('.control_panel .level');
var CLASS_CONTROLS = "control_panel";
var CLASS_RECORDING = "recording";
var CLASS_PLAYBACK_READY = "playback_ready";
var CLASS_PLAYING = "playing";
var CLASS_PLAYBACK_PAUSED = "playback_paused";

};
// Helper functions ---------------------------------------------------------------------------------------------------
function setUpFormOptions() {

});
當文件被保存在recorder.php中的上傳狀態之後會顯示一條綠色的消息。這是當點擊箭頭來保存/上傳upload.php即可生效，但未顯示。用戶如此說話仍然在頁面recorder.php上。
我做到了。一樣的東西。什麼都沒發生。 –
沒有解決。我還在上面添加了javascript文件main.js，這樣你就可以知道這個錄音機或多或少地起作用了。這是完整的Flash文件的鏈接：https：//github.com/michalstocki/FlashWavRecorder。 –
