Creating a Drop Down Menu in PHP from MySQL?

Question

I\'m sort of experienced with PHP and MySQL so I kind of get the hang of things, however I\'m sort of trying to get something that may be over my level (not really sure the diff

Answer 1

Create a div and give it a id="result" and put an empty select tag in that div.

Then using jQuery + Ajax, get the second dropdown using:

$('select[name="user"]').change(function(){
   var user = $(this).val();

   $.ajax({
      type:'post',
      url:'getSecondDropDown.php',
      data:'user='+user,
      success:function(result){
         $('div#result').html(result);
      }
   });

});

In your 'getSecondDropDown.php' file, include this:

<select name="task">
<?php
$user = $_POST['user'];
$q = mysql_query("SELECT task FROM tablename WHERE user=".$user.") or die();
while($r = mysql_fetch_array($q))
{ ?>
  <option value="<?php echo $r['task]; ?>"><?php echo $r['task]; ?></option>

<?php
}
?>
</select>

You'll need to use JavaScript to do it. Send an AJAX request to a page in the server which will fetch the details of a user for you, then return the results to JavaScript.

Once you have the data in your JavaScript, use DOM manipulation to populate the second <select> with the results.
