上传图片php mysql二进制

嗨，大家好，我一直收到一个错误，当我尝试上传时没有选择图片，上传表格肯定是上传的正确名称和编号，所以它必须是错误的代码，任何人都可以明白为什么？上传图片php mysql二进制

<?php 


// Create MySQL login values and 
// set them to your login information. 
$username = "**"; 
$password = "**"; 
$host = "**"; 
$database = "**"; 

// 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); 

    session_start(); 
    if(!isset($_SESSION['username'])) 
    { 
      die('You have no access to this page.'); 
    } 
    else{ 
    $username = $_SESSION['username']; 
    // Make sure the user actually 
    // selected and uploaded a file 
    if (isset($_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. 
    $query = "INSERT INTO Members WHERE username = '$username' "; 
    $query .= "(image) VALUES ('$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); 
    ?>

var_dump（$ _ FILES）''给你什么？要么你传入了一个空文件，要么你没有给文件输入正确的名称（期待“image”）。 – Halcyon 2012-03-29 22:57:51

您不应该使用addslashes，而应该使用mysql_real_escape_string来确保您完全防止sql注入。 – dsas 2012-03-29 23:06:12

可能您的<form>标记缺少enctype参数。它应该看起来像这样：

<form action="index.php?action=upload" method="post" enctype="multipart/form-data">
