我已经制作了一个允许您将文件附加到电子邮件的表单，但是每当有人添加附件时，表单会限制他们上传大于20,000 mb的内容，但我已将max-size设置为超过50 MB，有时它甚至不会允许这么多。我的问题是如何让表单接受大小为50 MB或更多的文件？这是我用于表单的代码。

以上是代码的html部分。
下面是代码的php部分。
//file upload validations
if(!empty($this->fileupload_fields))
{
if(!$this->ValidateFileUploads())
{
$ret = false;
}
}
return $ret;
}
function ValidateFileType($field_name,$valid_filetypes)
{
$ret=true;
$info = pathinfo($_FILES[$field_name]['name']);
$extn = $info['extension'];
$extn = strtolower($extn);
$arr_valid_filetypes= explode(',',$valid_filetypes);
if(!in_array($extn,$arr_valid_filetypes))
{
$this->add_error("Valid file types are: $valid_filetypes");
$ret=false;
}
return $ret;
}
function ValidateFileSize($field_name,$max_size)
{
$size_of_uploaded_file =
$_FILES[$field_name]["size"]/80000;//size in KBs
if($size_of_uploaded_file > $max_size)
{
$this->add_error("The file is too big. File size should be less than $max_size KB");
return false;
}
return true;
}
function IsFileUploaded($field_name)
{
if(empty($_FILES[$field_name]['name']))
{
return false;
}
if(!is_uploaded_file($_FILES[$field_name]['tmp_name']))
{
return false;
}
return true;
}
function ValidateFileUploads()
{
$ret=true;
foreach($this->fileupload_fields as $upld_field)
{
$field_name = $upld_field["name"];
$valid_filetypes = $upld_field["file_types"];
if(!$this->IsFileUploaded($field_name))
{
continue;
}
if($_FILES[$field_name]["error"] != 0)
{
$this->add_error("Error in file upload; Error code:".$_FILES[$field_name]["error"]);
$ret=false;
}
if(!empty($valid_filetypes) &&
!$this->ValidateFileType($field_name,$valid_filetypes))
{
$ret=false;
}
if(!empty($upld_field["maxsize"]) &&
$upld_field["maxsize"]>0)
{
if(!$this->ValidateFileSize($field_name,$upld_field["maxsize"]))
{
$ret=false;
}
}
}
我无法弄清楚是什么限制了表单的正常工作，但我还添加了一个ini_set（＆＃39; memory_limit＆＃39;，＆＃39; 250M＆＃39;）;
