从mysql填充的PHP下拉菜单不起作用

I've spent hours reading and trying to figure out why this is not working but the drop down menu does not populate. I think it's something simple but I just cannot see it. Anyone?

dbconn.php

<?php

define('DB_NAME' , 'artprints');
define('DB_USER' , 'root');
define('DB_PASS' , '');
define('DB_HOST' , 'localhost');

func.php

<?php

include_once 'dbconn.php';

function connect(){
    $connection = mysqli_connect(DB_HOST, DB_USER, DB_PASS) or die ('Could not connect to the database' . mysl_error());
    mysqli_select_db($connection, DB_NAME);
}

function close(){
    mysql_close();
}

function query(){
    $myData = mysql_query("SELECT * FROM artists");
    while ($record = mysql_fetch_array($myData)){
    echo '<option value="' . $record['artistID'] . '">' . $record['artistID'] . '</option>';
    }
}

test.php

<?php
 include_once 'func.php';
 connect();
 ?>

 <html>
 <head>
 <title>Drop down testing</title>
 </head>
 <body>
 <select name='artist'>
 <?php query() ?>
 </select>
 <?php close() ?>
 </body>
 </html>

You are mixing mysqli_* and mysql_*

mysqli_connect and mysqli_select_db

against

mysql_query and mysql_fetch_array

Copy and paste this in your function.php

include_once ('dbconn.php');

function connect()
{
    $connection = mysqli_connect(DB_HOST, DB_USER, DB_PASS) or die ('Could not connect to the database' . mysl_error());
    mysqli_select_db($connection, DB_NAME);
}

function close(){
    mysqli_close();
}

function query(){
    $myData = mysqli_query("SELECT * FROM artists");
    while ($record = mysql_fetch_array($myData)){
    echo '<option value="' . $record['artistID'] . '">' . $record['artistID'] . '</option>';
    }
}
