Php+mysql How to update the form contents to the database in a cyclic way

Php+mysql How to update the form contents to a database in a circular fashion
I currently need to dynamically create a form on a Web page, such as 10 lines, fill out the form and submit it via the form
The code is as follows:

PHP Code

I want to deal with it in the process.php,
$w = 0;
while ($row = Mysql_fetch_array ($result))
{
$filename = $row [' filename '];
$time 1 = $_post["$w"];
$w + +;
$time 2 = $_post["$w"];
$w + +;
$time 3 = $_post["$w"];
$w + +;
echo "w= at this time." $w. "
";
$sql = "UPDATE fileinfo SET time1=". $time 1. "', time2= '". $time 2. "', time3= '". $time 3. "' WHERE filename= ' ". $filename." ' ";
$re = mysql_query ($sql) or Die ("error:". Mysql_error ());
echo $sql. " ---result is: ". $re."
";
}

POST over the $time1, $time 2, $time 3 are empty values, changed to $time1 = $_post[$w] Also not, $time 1 = $_post[' $w '] also not, do not know $_post[] inside the value can be a variable, how to say ah .... How to deal with the situation of submitting a form!!

------Solution--------------------
Would you look at the foreground page and name it?
------Solution--------------------
Give it a try.

PHP code

 $i = 0;        while ($row = Mysql_fetch_array ($result)) {echo ""; echo "". $row [' filename '].        ""; echo "". $row [' FileSize ']. "";//The data table already has the file name and file size, but the playback time is default to 0, update the database through Web page modification echo "\ "Type=\"        Text\ ">";        echo "\ "type=\" text\ ">";        echo "\ "type=\" text\ ">"; echo "";    $i + +; 
------Solution--------------------
 You first Print_r ($_post) and look at 
------solution--------------------
 Echo \" type=\ "text\" > "; 
 echo "\ "type=\" text\ ">";
