頁腳DIV沒有顯示時，如果你想看到你是一個錯誤出現在上傳

Question

頁腳包括在與包括代碼導致此頁面這樣

<?php include "footer.php" ?> 

<center><div id="content"><br> 
<form method="post" enctype="multipart/form-data"> 
<input type="file" class="file" name="userfile"/><br> 
<br> 
<button name="upload" type="submit" value="Submit" class="upload">Upload</button> 
</form> 
<?php 
if(isset($_POST['upload'])) { 

$allowed_filetypes = array('.jpg','.jpeg','.png','.gif'); 
$max_filesize = 10485760; 
$upload_path = 'useruploads/'; 
$description = $_POST['imgdesc']; 

$filename = $_FILES['userfile']['name']; 
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); 

if(!in_array($ext,$allowed_filetypes)) 
die('<h4>The file you attempted to upload is not allowed.'); 

if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize) 
die('<h4>The file you attempted to upload is too large.'); 

if(!is_writable($upload_path)) 
die('<h4>You cannot upload to the specified directory, please CHMOD it to 777.'); 

if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename)) { 
$query = "INSERT INTO uploads (name, description) VALUES ($filename, $description)"; 
mysql_query($query); 

echo '<h5>Your file upload was successful!'; 


} else { 
echo '<h4>There was an error during the file upload. Please try again.'; 
} 
} 
?> 
</div> 

索引文件自我我有臨時上傳這個腳本到我的網站，所以你可以看到你的錯誤是自我嘗試和上傳不是圖像文件的東西，你會看到錯誤，我看到是否可以添加一個按鈕上傳完成後將其鏈接到圖片上

Website Link

這裏也是頁腳代碼

<center><div id="footer"> 
<p>Copyright &copy; OSPICTUREVAU 2014</p> 
</div> 

Answer 1

您正在使用die輸出你的錯誤die語句後，將停止所有代碼的執行。這意味着您的頁腳代碼從不執行。

Redirecton錯誤：

if (!in_array($ext, $allowed_filetypes)) 
    { 
    header("Location: errorpage.php"); 
    exit; 
    } 

您可以傳遞錯誤代碼到errorpage.php給用戶一個有意義的錯誤消息。
