我擁有一個名爲flopl.com的網站。這很基本。上傳您的文件，並返回一個鏈接到該文件的URL。但我不是編碼它的人，現在我無法再從那個人那裏得到幫助。代碼中存在錯誤，但我不知道該怎麼做。所以..下面的代碼：我的ajax有什麼問題？
HTML：
<!DOCTYPE html>
<html style="width:100%">
<head>
<title>flopl</title>
<link rel="stylesheet" href="style.css">
<meta charset="utf-8" />

.percent { position:absolute; display:inline-block; top:-1px; left:48%; }
</style>
</head>
<body style="width:100%">
<div style="background-color:#2d2d2d; width: auto; height:150px; padding:-10px; margin-top:-20px;">

//status.html(xhr.responseText);

});
});

而且PHP：
<?php
session_start();
$session_id='1'; // User session id
$path = "upload/";
function url($url) {
$url = preg_replace('~[^\\pL0-9_]+~u', '-', $url);
$url = trim($url, "-");
$url = iconv("utf-8", "us-ascii//TRANSLIT", $url);
$url = strtolower($url);
$url = preg_replace('~[^-a-z0-9_]+~', '', $url);
return $url;
}
if(!empty($_POST) && !empty($_FILES['photoimg']) && $_SERVER['REQUEST_METHOD'] == 'POST')
{
$name = $_FILES['photoimg']['name'];
$size = $_FILES['photoimg']['size'];
$pi = pathinfo($name);
$txt = $pi['filename'];
$ext = $pi['extension'];
$actual_image_name = time().$session_id.".".$ext;
$tmp = $_FILES['photoimg']['tmp_name'];
if(move_uploaded_file($tmp, $path.$actual_image_name))
{
echo "Here's the link to your file: <a href='http://flopl.com/".$path.$actual_image_name."'>http://flopl.com/".$path.$actual_image_name."</a>";
}
} else {
echo "Something went wrong.";
exit;
}
?>
的進度條顯示時，但我只得到 「出事了」 回來。我檢查過，PHP.ini設置正確。這些文件沒有上傳，因此也沒有給我回URL。
任何人都可以弄清楚什麼是錯的？
最好的問候， primarypanda
哦。我忘了說出了什麼問題。當您上傳1 MB以下的文件時，一切正常，但一旦超過該文件大小，URL將不會顯示，並且文件不會被上傳，儘管進度條上升到100％。我檢查了我的網站主機，他們允許更大的文件上傳，他們已經「證實」它是一個編碼問題。 – primarypanda
