[英]Add more custom variables to mysql insert on blueimp/jquery-file-upload
我目前正在通過mysql在blueimp / jquery-file-upload腳本中插入標題和描述。 我使用本教程可以到達那里,但是,我需要添加另一個變量。 該變量是當前已登錄用戶ID $_SESSION["userid"]
的會話,我想將其插入我添加的名為uid
的列中。 通常,將另一列隱含到插入中很簡單,但是此腳本非常敏感,每當我弄亂它時,即使是最細微的地方,我都會得到“ SyntaxError: Unexpected token <
”。 任何幫助將不勝感激。
$options = array(
'delete_type' => 'POST',
'db_host' => 'localhost',
'db_user' => 'fpform_fanuser',
'db_pass' => '*****',
'db_name' => 'fpform_fandata',

require('UploadHandler.php');
class CustomUploadHandler extends UploadHandler {
protected function initialize() {
$this->db = new mysqli(
$this->options['db_host'],
$this->options['db_user'],
$this->options['db_pass'],
$this->options['db_name']
);
parent::initialize();
$this->db->close();
}
protected function handle_form_data($file, $index) {
$file->title = @$_REQUEST['title'][$index];
$file->description = @$_REQUEST['description'][$index];
}
protected function handle_file_upload($uploaded_file, $name, $size, $type, $error,
$index = null, $content_range = null) {
$file = parent::handle_file_upload(
$uploaded_file, $name, $size, $type, $error, $index, $content_range
);
if (empty($file->error)) {
$sql = 'INSERT INTO `'.$this->options['db_table']
.'` (`name`, `size`, `type`, `title`, `description`)'
.' VALUES (?, ?, ?, ?, ?)';
$query = $this->db->prepare($sql);
$query->bind_param(
'sisss',
$file->name,
$file->size,
$file->type,
$file->title,
$file->description,
);
$query->execute();
$file->id = $this->db->insert_id;

return $file;

protected function set_additional_file_properties($file) {
parent::set_additional_file_properties($file);
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
$sql = 'SELECT `id`, `type`, `title`, `description` FROM `'
.$this->options['db_table'].'` WHERE `name`=?';

$query->bind_param('s', $file->name);

while ($query->fetch()) {
$file->id = $id;
$file->type = $type;
$file->title = $title;
$file->description = $description;

}
}
public function delete($print_response = true) {
$response = parent::delete(false);
foreach ($response as $name => $deleted) {
if ($deleted) {
$sql = 'DELETE FROM `'
.$this->options['db_table'].'` WHERE `name`=?';
$query = $this->db->prepare($sql);
$query->bind_param('s', $name);
$query->execute();

return $this->generate_response($response, $print_response);
}
}
$upload_handler = new CustomUploadHandler($options);
假設您要更改INSERT查詢(您發布的代碼中只有一個INSERT查詢),則需要更改以下內容:
if (empty($file->error)) {
$sql = 'INSERT INTO `'.$this->options['db_table']
.'` (`name`, `size`, `type`, `title`, `description`, `uid`)'
.' VALUES (?, ?, ?, ?, ?, ?)';
$query = $this->db->prepare($sql);
$query->bind_param(
'sisss',
$file->name,
$file->size,
$file->type,
$file->title,
$file->description,
$_SESSION['userid']
);
$query->execute();
$file->id = $this->db->insert_id;
}
protected function handle_file_upload($uploaded_file, $name, $size, $type, $error,
$index = null, $content_range = null, $uid) {
$file = parent::handle_file_upload(
$uploaded_file, $name, $size, $type, $error, $index, $content_range, $uid
);
$uid=$_SESSION['userid'];
if (empty($file->error)) {
$sql = 'INSERT INTO `'.$this->options['db_table']
.'` (`name`, `size`, `type`, `title`, `description`,`uid`)'
.' VALUES (?, ?, ?, ?, ?,?)';
$query = $this->db->prepare($sql);
$query->bind_param(
'sisssi',
$file->name,
$file->size,
$file->type,
$file->title,
$file->description,
$file->uid
);
$query->execute();
$file->id = $this->db->insert_id;
}
return $file;
}`
我認為您必須在bind_param的第一個參數中添加另一個條目:
$query->bind_param(
**'sisss',**
$file->name,
$file->size,
$file->type,
$file->title,
$file->description,
$_SESSION['userid']
應該
$query->bind_param(
**'sissss',**
$file->name,
$file->size,
$file->type,
$file->title,
$file->description,
$_SESSION['userid']
當然,請減去星號或任何正確的數據類型(請參閱http://us.php.net/manual/zh-cn/mysqli-stmt.bind-param.php中的參數類型部分)。
奇怪的是,我嘗試傳遞文字字符串作為最后一個參數,這引發了此錯誤:
“ PHP致命錯誤:在第66行的/var/www/html/jqfileuploadertest/server/php/index.php中無法通過引用傳遞參數7”
但是,當我將“ mystring”更改為$ file-> name時,它可以正常工作。 這將需要一些努力,因為我想為這些時間戳記...我感覺只是添加“ NOW()”是行不通的...
更新:我想為每個文件添加兩個字段,即上載文件的人的ID(我認為這是OP想要做的事情)以及時間戳。 我將它們作為隱藏輸入添加為以下形式:
<input name="contributor[]" type="hidden" value="myuserid" />
<input name="uploadedOn[]" type="hidden" value="2014-03-28 10:00:00" />
如果您的表單是一個php腳本,則可以動態生成兩者。
然后將其添加到index.php行〜44:
$file->contributor = @$_REQUEST['contributor'][$index];
$file->uploadedOn = @$_REQUEST['uploadedOn'][$index];
並修改了准備SQL語句的index.php的這一部分:
if (empty($file->error)) {
$sql = 'INSERT INTO `'.$this->options['db_table']
.'` (`name`, `size`, `type`, `title`, `description`,`contributor`, `dateUploaded`)'
.' VALUES (?, ?, ?, ?, ?, ?, ?)';
$query = $this->db->prepare($sql);
$query->bind_param(
'sisssss',
$file->name,
$file->size,
$file->type,
$file->title,
$file->description,
$file->contributor,
$file->uploadedOn
);
而且有效。
上傳文件時,您在JavaScript控制台中遇到的錯誤是對的嗎? 在我看來,正在加載的文件之一未找到404,並且它實際上嘗試將接收到的404頁解析為腳本文件,而實際上它是一個以<...開頭的html文件,我以前曾經發生過這種情況。 在網絡下檢查並查看發生時正在加載的所有資源。 也可能沒有返回正確的404標頭,這就是為什么它將嘗試解析它。
