<?php
$hostname = "localhost";
$username = "";
$password = "";
$database = "";

// Connect to the database
mysql_connect($hostname, $username, $password) OR DIE("Unable to connect");
mysql_select_db("$database") or die("Unable to select database");

if (isset($_POST['ud_date'])) {
   $query = sprintf("UPDATE test_mysql SET content='%s' WHERE id=%d",
                mysql_real_escape_string($_POST['ud_date']),
                2);
   if (mysql_query($query)) {
       echo 'update query succeeded';
   } else {
       else echo 'update query failed';
   }
} else {
   echo 'please submit the form';
}

There is only one column you can (or should) update.... the Content column. the ID column is your primary key, so you really shouldn't be changing that. ....so... I'm not sure what the problem is... unless there's more to the table structure that you're not telling us. Also, the use of ud_date as the ID field in the post form seems counterintuitive. I would expect something called ud_date to contain a date value...

yes boss that content column only,

i want to update that content columns with different text.

Are you saying you want your data to look like this:

+----+---------+
| id | content |
+----+---------+
| 2 | new |
+----+---------+
| 14 | new |
+----+---------+

updating id=2 and id=14 to a new value?
