Can someone please help me understand why the below function works in option.php but does not work in main.php? From what I'm seeing, it looks as if the query is not going through when the function is called on main.php; however, it clearly goes through on option.php.
custom_functions.php
function fetch_options(){
global $connection;
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);
while($row = mysqli_fetch_assoc($result)){
echo "<option value=\"{$row['a']}\">{$row['b']}</option>";
}
mysqli_free_result($result);
mysqli_close($connection);
}
option.php
<?php
require_once('lib/db.php');
require_once('lib/custom_functions.php');
echo "<select><option value=\"0\">Unknown</option>";
fetch_options();
echo "</select>";
?>
main.php
<?php
require_once('lib/db.php');
require_once('lib/custom_functions.php');
?>
