php请求完成后激活标题

我目前正在一个网站上工作，用户可以上传高达10mb的图像。当用户按upload时，文件存储在服务器上的一个目录中，然后通过使用页眉重定向页面。注意，我还将ob start放在脚本的开头。我遇到的问题是，头重定向在请求完成之前激活，因此用户会注销，或者发生内部服务器错误。删除大文件时也会发生同样的情况。我已经尝试过删除重定向，它很好，所以我确信这就是问题所在。是否只有在php请求图像上传完成后，才有办法获得标题重定向

谢谢

编辑：代码示例

if (empty($errors)) {

  // Get the filename minus the file extension:
$filename = substr($image["name"], 0, strrpos($image["name"], "."));
// Append the appropriate extension
$filename .= $validMimes[$image['type']];
$location = "/home/shoplft/users/$user_id/$foldername/$filename";  
  move_uploaded_file($tmp_name, $location);




  if($secondcategory=="0") {


     mysql_query("INSERT INTO products (users_user_id, name, brand, city, country, store, website, price, keywords, productlocation, filename) VALUES ('$user_id', '$productname', '$productbrand', '$city', '$country', '$store', '$website', '$price', '$tagwords', '$location', '$filename')") or die('Invalid query: ' . mysql_error());

     $pic_id = mysql_insert_id();

     mysql_query("INSERT INTO categories (products_products_id, products_users_user_id, category) VALUES('$pic_id', '$user_id', '$firstcategory')");

     if(!empty($price)) {

        mysql_query("INSERT INTO svalues (products_products_id, products_users_user_id, svalue) VALUES ('$pic_id', '$user_id', '$price') ");

     }




  }



  else {

  mysql_query("INSERT INTO products (users_user_id, name, brand, city, country, store,   website, price, keywords, productlocation, filename) VALUES ('$user_id', '$productname', '$productbrand', '$city', '$country', '$store', '$website', '$price', '$tagwords', '$location', '$filename')") or die('Invalid query: ' . mysql_error());

  $pic_id = mysql_insert_id();

 mysql_query("INSERT INTO categories (products_products_id, products_users_user_id, category) VALUES('$pic_id', '$user_id', '$firstcategory')");
 mysql_query("INSERT INTO categories (products_products_id, products_users_user_id, category) VALUES('$pic_id', '$user_id', '$secondcategory')");

  if(!empty($price)) {

        mysql_query("INSERT INTO svalues (products_products_id, products_users_user_id, svalue) VALUES ('$pic_id', '$user_id', '$price') ");

     }  


  }

header("Location: product.php?id=$pic_id");//prolly should separate data processing from output

 }    

试试这个

if (empty($errors)) {

  // Get the filename minus the file extension:
$filename = substr($image["name"], 0, strrpos($image["name"], "."));
// Append the appropriate extension
$filename .= $validMimes[$image['type']];
$location = "/home/shoplft/users/$user_id/$foldername/$filename";
if(!@copy($tmp_name, $location))
{
$errors[] =  'Error';
}

if (empty($errors))
{




  if($secondcategory=="0") {


     mysql_query("INSERT INTO products (users_user_id, name, brand, city, country, store, website, price, keywords, productlocation, filename) VALUES ('$user_id', '$productname', '$productbrand', '$city', '$country', '$store', '$website', '$price', '$tagwords', '$location', '$filename')") or die('Invalid query: ' . mysql_error());

     $pic_id = mysql_insert_id();

     mysql_query("INSERT INTO categories (products_products_id, products_users_user_id, category) VALUES('$pic_id', '$user_id', '$firstcategory')");

     if(!empty($price)) {

        mysql_query("INSERT INTO svalues (products_products_id, products_users_user_id, svalue) VALUES ('$pic_id', '$user_id', '$price') ");

     }




  }



  else {

  mysql_query("INSERT INTO products (users_user_id, name, brand, city, country, store,   website, price, keywords, productlocation, filename) VALUES ('$user_id', '$productname', '$productbrand', '$city', '$country', '$store', '$website', '$price', '$tagwords', '$location', '$filename')") or die('Invalid query: ' . mysql_error());

  $pic_id = mysql_insert_id();

 mysql_query("INSERT INTO categories (products_products_id, products_users_user_id, category) VALUES('$pic_id', '$user_id', '$firstcategory')");
 mysql_query("INSERT INTO categories (products_products_id, products_users_user_id, category) VALUES('$pic_id', '$user_id', '$secondcategory')");

  if(!empty($price)) {

        mysql_query("INSERT INTO svalues (products_products_id, products_users_user_id, svalue) VALUES ('$pic_id', '$user_id', '$price') ");

     }


  }

header("Location: product.php?id=$pic_id");//prolly should separate data processing from output
 }
 }

代码示例？上传代码上面有重定向代码吗？这将是一个明显的原因。@MichaelRushton，是的，我在最后有它。它也只在大文件上，很奇怪！我尝试了你的代码，我得到了文件错误上传消息尝试删除@符号行如果@移动上传的文件$tmp\U名称，$location？如果这不起作用，新代码会起作用，请查看。那个move_上传的文件似乎是为了另一个目的：PMerrick，没有骰子？刚喝了杯咖啡。我不想打扰你，但那东西似乎还有其他问题。职能应该发挥作用。只是想问一下，您是在本地工作还是在主机服务器上工作？
