我使用“php do”和“php while”来显示所有记录。并且每条记录都有“更新记录”按钮，我试图做一个按钮来更新这些记录。我只需要一个按钮来更新它们，任何人都可以帮我完成吗？

这是代码：

<?php require_once('Connections/tlsc_conn.php'); ?>
<?php
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
  $updateSQL = sprintf("UPDATE tb_exam SET answer1=%s, answer2=%s, answer3=%s, answer4=%s, correct=%s WHERE question_id=%s",
                       GetSQLValueString($_POST['answer1'], "text"),
                       GetSQLValueString($_POST['answer2'], "text"),
                       GetSQLValueString($_POST['answer3'], "text"),
                       GetSQLValueString($_POST['answer4'], "text"),
                       GetSQLValueString($_POST['correct'], "text"),
                       GetSQLValueString($_POST['question_id'], "int"));

  mysql_select_db($database_tlsc_conn, $tlsc_conn);
  $Result1 = mysql_query($updateSQL, $tlsc_conn) or die(mysql_error());
}

mysql_select_db($database_tlsc_conn, $tlsc_conn);
$query_Recordset1 = "SELECT * FROM tb_exam";
$Recordset1 = mysql_query($query_Recordset1, $tlsc_conn) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
?>
