?>:

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";

}

?>
