[Newbi]

What i want is for the user to be able to enter a staff no & date
to retrieve other data from a table. the only thing is my date is structured in three columns so i dont know if i can do this. Thankyou in advance.

<?php
ini_set('display_errors',1); 
error_reporting(E_ALL);
$dbhost = "localhost";  // variable holding host information
$dbname = "sportscentre";  // variable holding the name of the database
$dbuser = "*****";  // variable holding the username of the person using database account
$dbpass = "****";  // variable holding password of the person using database account

$connection = mysql_connect($dbhost, $dbuser, $dbpass)or die("Cannot connect");
// The mysql_connect() function is what is used to make the connection to the database it takes three parameters as listed above the hostname, the database users username and the database users password.

$connection = mysql_select_db($dbname)or die("cannot select DB");
// The mysql_select_db() funtion is used to connect to the database that we are going to work with. The parameter for this is the database name and a message to the user in case the connection fails.

 // A list of variable to hold all the information entered in the form so that 
// it can then referred to in the insert query.
$day = $_POST['day'];
$month = $_POST['month'];
$year = $_POST['year'];
$staffno = $_POST['staff_no'];

if (isset($_POST['submitted'])) { // To check if the form has been submitted.

$errors = array(); // Initialize error array.	

if(empty($_POST['staff_no']))  // If the drop down box for staff no is empty, the display the message on the line below. 
{
	$errors[]= 'Please select a staff no';
}

if(empty($_POST['day']))  // If the drop down box for day is empty, the display the message on the line below. 
{
	$errors[]= 'Please select a day';
}

if(empty($_POST['month']))  // If the drop down box for month is empty, the display the message on the line below. 
{
	$errors[]= 'Please select a month';
}

if(empty($_POST['year']))  // If the drop down box for year is empty, the display the message on the line below. 
{
	$errors[]= 'Please select a year';
}

if (count($errors)==0)  //If there are no errors in the error array then do the following insert query.
{

$query = "select staff_no, booking_ref_no, membership_no, class, day, month, year, time, teacher from classbooking where staff_no = '$staffno' and day = '$day' and month = '$month' and year = '$year'";

$result = mysql_query($query)or die ("Query failed: " . mysql_error());

echo "<table border = '1'>"; // This is basically echoing the table and header columns.
echo "<tr>";
echo "<th width = 25>Staff No</th><th>Booking Ref No</th><th>Membership No</th><th>Class</th><th>Date</th><th>Time</th><th>Teacher</th>";
echo "</tr>";

while ($row = mysql_fetch_array($result)) // while the function  mysql_fetch_array() is fetching the result display to the page each row there is in the database.
{
echo "<tr>";
echo "<td>", $row['staff_no'], "</td><td>", $row['booking_ref_no'],"</td><td>", $row['membership_no'],  $row['class'],"</td><td>", $row['day'], - $row['month'], - $row['year'], "</td><td>", $row['time'],"</td><td>", $row['teacher'],"</td>";
echo "</tr>";
}
echo "</table>";


}
else

{ // Advise of the errors.
	
		echo '<h3>Error!</h3>
		<p>The following error(s) occurred:<br />';
		foreach ($errors as $msg) { // Print each error.
			echo " - $msg<br />\n";
		}
		echo '</p><p>Please try again.</p><p><br /></p>';
	} 
	
}
mysql_close();   // close connection
?>

It isn't quite clear why you are asking the question. You can select from the db on multiple fields so it doesn't matter what they are. As long as you are looking for an exact match, it should be no problem. If you wanted to do a greater or less than it would be a different story.

Another approach for the input would be to have a single date input field and then use strtotime to turn it into a time stamp. Then use date to extract the day, the month and the year. You can make it a little bit friendlier for the user.
