Good evening,

i have a problem with some code. I´ve created a dropdownlist that gests it´s values from a database. 

The dropdownlist is being populated without problems. My problem is that i must get the selected value from the

dropdown to complete my task. But i don´t know how. I´d appreciate some help. I send some of the code:

 

echo'  <form action="permissions.php" method="post" id="form">

     <table><tr><td>Seleccionar Utilizador:</td><td><select name="utilizadores" id="utilizadores">';
$query = mysql_query("SELECT * FROM `users`");
echo'<option value="">****** Utilizador *******</option>';
 while(($row = mysql_fetch_array($query))!== false)
{  
    echo '<option value="'.$row["user_id"].'">'.$row["first_name"].' '.$row["last_name"].'</option>';
}
echo '</select></td>
 
</tr>
</table>';
 
I must get the value selected by the user, without posting because i have to use that value for a database search, so i can
display further values. Appreciated some help. I´m desperate :-(
 
Many thanks,
TorSunTsu

You need to check if the posted value is the same as the value you're adding to the list, then you can set the selected attribute to the option.

while(($row = mysql_fetch_array($query))!== false)
{
    $selected = (isset($_POST['utilizadores']) && $row['user_id'] == $_POST['utilizadores']) ? ' selected' : '';
    echo '<option value="'.$row["user_id"].'"'.$selected.'>'.$row["first_name"].' '.$row["last_name"].'</option>';
}
