在PHP错误中上传图像

Question

PHP代码：insert.php

<?php
// Create MySQL login values and
// set them to your login information.
$username = "root";
$password = "";
$host = "localhost";
$database = "binary";

// Make the connect to MySQL or die
// and display an error.
$link = mysql_connect($host, $username, $password);
if (!$link) {
die('Could not connect: ' . mysql_error());
}

// Select your database
mysql_select_db ($database);


// Make sure the user actually
// selected and uploaded a file
if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) {

// Temporary file name stored on the server
$tmpName = $_FILES['image']['tmp_name'];

// Read the file
$fp = fopen($tmpName, 'r');
$data = fread($fp, filesize($tmpName));
$data = addslashes($data);
fclose($fp);


// Create the query and insert
// into our database.
$query = "INSERT INTO tbl_images ";
$query .= "(image) VALUES ('$data')";
$results = mysql_query($query, $link);

// Print results
print "Thank you, your file has been uploaded.";
}
else {
print "No image selected/uploaded";
}

// Close our MySQL Link
mysql_close($link);
 ?>



 ?> 

HTML代码：add.html

 <form enctype="multipart/form-data" action="insert.php" method="post" name="changer">
 <input name="MAX_FILE_SIZE" value="102400" type="hidden">
 <input name="image" accept="image/jpeg" type="file">
 <input value="Submit" type="submit">

现在我正在尝试上传图像并将图像保存到我的MYSQL数据库。问题是它没有正确上传文件，或者没有正确地将图像传输到insert.php文件。当我上传文件时，它显示正确的建议上传，但在我点击提交后，它回声没有选择/上传的图像？＆gt;如果它无法从add.html帖子中获取数据，那么这是一个被告知要执行的命令。有人可以帮我弄清楚发生了什么吗？
