最后是写入数据库
//editdb.php
$database = "sunsite";
$tablename = $_POST['tablename'];
mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");
$query = "show columns from $tablename";
$result = mysql_db_query($database,$query);
$column = 0;
if ($result)
{
while ($r = mysql_fetch_array($result))
{
$colname[$column] = $r[0];
$column = $column + 1;
}
mysql_free_result($result);
}
for($col=0;$col$para[$col] = $_POST[$colname[$col]];
if ($_POST['name'])
{
mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");
$query = "update $tablename set $colname[1]='$para[1]'";
for($col=2;$col$query = $query . ",$colname[$col]='$para[$col]'";
$query = $query . " where $colname[0]='$para[0]';";
$result = mysql_db_query($database, $query);
Header("Location: edit.php?tablename=$tablename");
}
else
{
echo "No name Entered. Please go back and reenter name";
