I have an html page that loads list of hotels in a select tag from a MySQL table using PHP. The select tag is inside a form tag. Whenever I load the page, the option tags will load, but when I submit my form, the option tags never load anymore. My form's action attribute is empty, I am checking everything on the same page, but when I put another php page as action, it loads normally. Is there a way to make it load after submit while keeping my form's action empty?
Here is my code
<?php
require_once 'db.php';
$db = DB::get_instance();
if(isset($_POST['search'])) {
$hotel = $_POST['hotel_list'];
$db->query("SELECT * FROM hotels WHERE Name='$hotel'");
$hotel = $db->result()->current();
$hid = $hotel['Hid'];
$db->query("SELECT * FROM rooms WHERE Hid='$hid'");
$rooms = $db->result();
$db->disconnect();
}
?>
<!doctype html>
<html>
<head>
<title>Display a hotel</title>
</head>
<body>
<form action="" method="post" id="dsphtl">
Name: <select name="hotel_list" form="dsphtl">
<?php
$db->query("SELECT Name FROM hotels ORDER BY Name");
foreach($db->result() as $row) {
$t = $row['Name'];
echo "<option value='$t'>$t</option>";
}
?>
</select>
<input type="submit" value="Search" name="search">
</form>
</body>
</html>
