IE下的HTML5问题(HTML5 under IE questions)

 当我开始将我的主网站改为全新的HTML5时，我的一天结束时非常糟糕，但......  
 我看到HTML5网站 ，一切看起来都很好，所以，当我完成我的时候我非常高兴......好吧， 当我搬到一台Windows机器时 :(不

 在Internet Explorer下， 这显示什么都没有 ...我内心如此反抗你无法想象，我认为它必须是简单的东西，但我不能只是找到它是什么...  
 如果将所有HTML5新标签重命名为<div>标签 ，则网站显示但不在中心位置...  
 我一直以为所有新的HTML5标签都会回滚到<div> s ...  
 关于我做错了什么，任何人都可以帮助我吗？ 我忘记了这一切吗？ 谢谢 。  
 网站在IE9预览版上运行良好，以及所有其他浏览器（Safari，Mobile Safari，FF，Opera，Chrome等）......  
 :-(  
 
  PS这是一个非常绝望的家伙的问题！  

I'm getting a really bad end of a day as I started to change my main website to the brand new HTML5, but ... 
I see HTML5 websites and everything looks fine on them, so, when I finished mine I was very pleased... well, not when I moved to a windows machine :(

under Internet Explorer, this shows absolutely nothing... I'm so revolted inside that u can't imagine, I think it has to be something simple, but I can't just find what it is ... 
if a rename all HTML5 new tags into <div> tags, the website shows but not in a central position... 
I always thought that all new HTML5 tags would roll back into <div>s ... 
can anyone assist me, on what I'm doing wrong? what am I forgetting in all this? Thank you. 
website works fine on IE9 Preview though, and all other browsers (Safari, Mobile Safari, FF, Opera, Chrome, etc)... 
:-( 
 
 P.S. this is a question from a really desperate fellow!

 为什么你没有为它写一个条件，就像用户更改了照片然后你会得到它的名字，但如果用户没有，你会得到该字段为空。  
    if(isset($_FILES['file']) && !empty($_FILES['file']['name'])){
     $filename  = basename($_FILES['file']['name']);// i am not getting value here
     $extension = pathinfo($filename, PATHINFO_EXTENSION);
     $new_name= md5($filename.time()).'.'.$extension;
     $update = mysql_query("UPDATE task_employee SET emp_lastname='$lstname',emp_main_photo = '$new_name' WHERE emp_id='".$_SESSION['emp_id']."'");
   }else{
     $update = mysql_query("UPDATE task_employee SET emp_lastname='$lstname' WHERE emp_id='".$_SESSION['emp_id']."'");
   }

Why don't you have write a condition over it like if user changed photo then you will get its name but if the user doesn't you will get that field empty. 
    if(isset($_FILES['file']) && !empty($_FILES['file']['name'])){
     $filename  = basename($_FILES['file']['name']);// i am not getting value here
     $extension = pathinfo($filename, PATHINFO_EXTENSION);
     $new_name= md5($filename.time()).'.'.$extension;
     $update = mysql_query("UPDATE task_employee SET emp_lastname='$lstname',emp_main_photo = '$new_name' WHERE emp_id='".$_SESSION['emp_id']."'");
   }else{
     $update = mysql_query("UPDATE task_employee SET emp_lastname='$lstname' WHERE emp_id='".$_SESSION['emp_id']."'");
   }
