Question

When I execute this code, I only get zeroes inserted into my database. Why? What can I do to solve this problem?

<select class="date" name="year"> <option value="">Year</option>
<?php $i=1; while($i<=31) { ?>
<option value="<?php $i ?>"> <? echo $i; ?> </option>
<?php $i++; } ?> </select>

And this is my mysql code:

$sql="INSERT INTO information ( Year ) 
VALUES ('$_POST[year]')";

Answer 1

here how it will be your code

     <select class="date" name="year">
       <option value="">Year</option>
         <?php  for($i=1;$i<=31 ;$i++ ) { ?>
       <option value="<?php $i ?>"> <? echo $i; ?> </option>
         <?php } ?>
     </select>

EDIT :

    <input type ="submit" value =" submit me"/>
    <?php  if (isset($_POST['year']))  // check if isset the year
       {
       $year = $_POST['year']  ;
       } else {}



    $sql="INSERT INTO information ( Year ) VALUES ('".$year."')";
       ?>

edit 2 :
your code is right but you should escape value to prevent sql injection
do like that

insert into ....
    VALUES
       ('mysql_real_escape_string($_POST[user])','mysql_real_escape_string($_POST[email])'.........
