How to populate HTML dropdown list with values from database

Question

as part of a HTML form I am creating I would like to have a dropdown list which will list all the usernames in my database.

I thought the following code would do the trick but the dropdown list is empty - could someone assist me in what i'm doing wrong? Thanks.

<tr>
<td>Owner</td>
<td>
<select name="owner">
<?php 

$sql = mysqli_query($connection, "SELECT username FROM users");

while ($row = $sql->fetch_assoc()){

?>
<option value="owner1"><?php echo $row['username']; ?></option>

<?php
// close while loop 
}
?>
</td>
</tr>

Answer 1

My guess is that you have a problem since you don't close your select-tag after the loop. Could that do the trick?

<select name="owner">
<?php 
$sql = mysqli_query($connection, "SELECT username FROM users");
while ($row = $sql->fetch_assoc()){
echo "<option value=\"owner1\">" . $row['username'] . "</option>";
}
?>
</select>
