首先,我對PHP很陌生,使用Jquery更好一些。我設法建立一個上傳iFrame上傳圖片到一個網上商店的Dropbox帳戶。如何獲取上傳文件前的ID
所以有人把T恤放在購物車中,然後需要上傳一些藝術品。客戶點擊「上傳」併發送到具有保管箱上傳腳本的iFrame。 iFrame的url是這樣的 - >http://webshop.com/dropbox/index.html?id=10102013-88981
到目前爲止好。然而問題是,當兩個人上傳一個具有相同名稱的文件時,第一個文件正在更新。所以我需要在文件前面有一個唯一的ID。該唯一標識是網址末尾的參數。
所以問題是如何獲得在URL的末尾的id和如何把它放在上傳的圖像?
Ideal可以是文件名的前綴或將所有內容存儲在自己的文件夾中。 我嘗試了幾件事,但我的知識是有限的,所以任何幫助非常感謝。
上傳腳本:
//Start the upload code.
........
......
if(sizeof($_FILES)===0){
echo "<li>No files were uploaded.</li>";
return;
}
foreach ($_FILES['ufiles']['name'] as $key => $value) {
if ($_FILES['ufiles']['error'][$key] !== UPLOAD_ERR_OK) {
echo $_FILES['ufiles']['name'][$key].' DID NOT upload.';
return;
}
$tmpDir = uniqid('/tmp/DropboxUploader-');
if (!mkdir($tmpDir)) {
echo 'Cannot create temporary directory!';
return;
}
$tmpFile = $tmpDir.'/'.str_replace("/\0", '_', $_FILES['ufiles']['name'][$key]);
if (!move_uploaded_file($_FILES['ufiles']['tmp_name'][$key], $tmpFile)) {
echo $_FILES['ufiles']['name'][$key].' - Cannot rename uploaded file!';
return;
}
try {
$uploader = new DropboxUploader($drop_account, $drop_pwd);
$uploader->upload($tmpFile, $drop_dir);
echo "<li>".$_FILES['ufiles']['name'][$key]."</li>" ;
// Clean up
if (isset($tmpFile) && file_exists($tmpFile))
unlink($tmpFile);
if (isset($tmpDir) && file_exists($tmpDir))
rmdir($tmpDir);
} catch(Exception $e) {
$error_msg = htmlspecialchars($e->getMessage());
if($error_msg === 'Login unsuccessful.') {
echo '<li style="font-weight:bold;color:#ff0000;">Unable to log into Dropbox</li>';
return;
}
if($error_msg === 'DropboxUploader requires the cURL extension.') {
echo '<li style="font-weight:bold;color:#ff0000;">Application error - contact admin.</li>';
return;
}
echo '<li>'.htmlspecialchars($e->getMessage()).'</li>';
}
}

好THX你的答案!問題是現在文件名是-file.jpg而不是1234-file.jpg。 'get [id]'是我嘗試過的,但不會從iFrame網址獲取id。這是否與它是iFrame的事實有關? – Meules
更新...如果這不起作用發佈您的代碼爲您的
好的thx,你會看看。這是一個很大的幫助。我已經更新了完整的代碼......它有點長;) – Meules
