表單不會更新用戶配置文件

Question

我有一個上傳電子簽名圖像到用戶配置文件的問題，雖然我找不到我出錯的地方:(我確實在所有其他文件中包含了「簽名」規定......我思念的東西？

<?php 

if (isset($_GET['success']) === true && empty($_GET['success']) === true) { 
    echo 'Your details have been updated!'; 
} 
else { 
    if (empty($_POST) === false && empty($errors) === true) { 

     $update_data = array(
      'username' => $_POST['username'], 
      'fullname' => $_POST['fullname'], 
      'email' => $_POST['email'], 
      'contact1' => $_POST['contact1'], 
      'contact2' => $_POST['contact2'], 
      'businessaddress' => $_POST['businessaddress'], 
      'businessprovince' => $_POST['businessprovince'], 
      'businesstown' => $_POST['businesstown'], 
      'businesszip' => $_POST['businesszip'], 
      'businessnumber' => $_POST['businessnumber'], 
      'businessfax' => $_POST['businessfax'], 
      'hrnumber' => $_POST['hrnumber'], 
      'hremail' => $_POST['hremail'], 
      'hrperson' => $_POST['hrperson'], 
      'signature' => $_POST['signature'], 
      'allow_email' => ($_POST['allow_email'] == 'on') ? 1 : 0 
     ); 

     update_user($session_user_id, $update_data); 
     header('Location: settings.php?success'); 
     exit(); 
    } 
    else if (empty($errors) === false) { 
     echo output_errors($errors); 
    } 

    function update_user($user_id, $update_data) 
    { 
     $update = array(); 
     array_walk($update_data, 'array_sanitize'); 

     foreach ($update_data as $field => $data) { 
      $update[] = '`' . $field . '` = \'' . $data . '\''; 
     } 

     mysql_query("UPDATE `users` SET " . implode(', ', $update) . " WHERE `user_id` = $user_id"); 
    } 

} 
?>

Answer 1

你有一個「簽名」的HTML文件場，你就從$ _ POST閱讀它一樣，如果它是一個字符串（是不是）。

上傳PHP中的文件將用有用的數據填充$ _FILES以檢索文件。

在你的情況下，$ _FILES ['signature'] ['tmp_name']將是一個字符串，表示文件被臨時存儲的位置。

如果你想保存文件的地方，你必須做這樣的事情：

$tmp_name = $_FILES['signature']['tmp_name']; 
$path = "/some/path/".$_FILES['signature']['name']; 
move_uploaded_file($tmp_name, $path); 

並不僅僅是讀書$ _ POST [「簽名」（其中，順便說一下，將不會設置）。
