Values from input fields will only be sent if a form has been submitted.

 

So you need to wrap your <select> field in a form and then submit the form using a button example

<form action="add_group.php" method="get"> <!-- start form -->

<select name='group' id='group' >   <!-- dropdown input field -->
<?php 
while ($line = mysql_fetch_array($result)) {
echo '<option value=' . $line['ugroup'] . '>' . $line['ugroup'] . '</option>';


}?>
</select>
<input type="submit" value="Go" /> <!-- the submit button -->
</form>

Now in add_group.php you'd use $_GET['group'] to retrieve the submitted value.

 

You can do away with submit button and submit the form by applying onchange event handler to select field.

What does "doesn't work" mean?

 

It would be helpful if you told use what it is you are trying to do.

when user click on submit i want to pass php select option value to add_group.php .in add_group.php should update ugroup value according to that passed value.

i'v tryed your code.but it doesn't update table value.

It's cause you chose to get ugroup instead of what you named the select field. Wich is group
