Question

I’m trying to make a dropdownlist based on data I get from the database but I can’t display them. Could someone lend me a hand?

include '../opdrachten/connectionPDO.php';

function Select()
{

$query =$db->prepare("SELECT naam FROM opdracht4");
$query->execute();

foreach ($query as $row)
{
echo '<option value="'.$row['naam'].'">"'.$row['naam'].'"</option>';    
}
} 

<select name="projectleider">   
<?php Select();  ?>
</select>

Answer 1

Pass the $db into the function to get it in scope.

include '../opdrachten/connectionPDO.php';

function Select($db)
{

$query =$db->prepare("SELECT naam FROM opdracht4");
$query->execute();

foreach ($query as $row)
{
echo '<option value="'.$row['naam'].'">"'.$row['naam'].'"</option>';    
}
} 

<select name="projectleider">   
<?php Select();  ?>
</select>
