I have a database (db_exams) with a table called db_dates. Here timeslots are stored together with a number.
db_date stores the timeslots
db_count stores a number (the number of times the specific timeslot can be used)
the timeslots are then printed in a html form with a select box.
people can then fill in the form to book a timeslot (stored in db_booking).
now when a certain timeslot is booked full (based upon db_count and counted in db_booking) i want it to be hidden from the select.
<div><input type="text" id="fname" name="fname"></div>
<div><input type="email" id="email" name="email"></div>
<div><label for="Ploeg">Select timeslot:</label></div>
<option disabled selected>select timeslot</option>
include "config.php"; // Using database connection file here
$records = mysqli_query($db, "SELECT date From dates"); // Use select query here
while($data = mysqli_fetch_array($records))
echo "<option value='". $data['date'] ."'>" .$data['date'] ."</option>"; // displaying data in option menu
