Thanks to rIkLuNd.
Now I have another question.
next code is in index.php
<FORM action="insert.php" method="post">
<select name="day">
<option value="Mon">Mon</option>
<option value="Tue">Tue</option>
<option value="Wed">Wed</option>
<option value="Thu">Thu</option>
<option value="Fri">Fri</option>
<option value="Sat">Sat</option>
<option value="Sun">Sun</option>
</select>
<input type=submit name=submission value="click">
</FORM>
next code is in insert.php
<?
$dbcnx=@mysql_connect('localhost','root',"********");
$status=mysql_select_db("test", $dbcnx);
$day=$_POST['day'];
$sql="INSERT INTO table1(day) VALUES('$day')";
$sql=mysql_query($sql)
?>
My problem at the moment is that the selected value (Mon~Sun)
isn't inserted into the test table.
How can I make the selected value(Mon~Sun) into the day field in the table1 ?
