Ok I am making a booking system in PHP / Mysql and so far

  • 0

Ok I am making a booking system in PHP / Mysql and so far I just have a basic form made to test inserting data but I want to improve it to only show time slots that are avalible.

I have used the following so far after asking earlier;

function mysql_fetch_rowsarr($result, $numass=MYSQL_BOTH) {
  $i=0;
  $keys=array_keys(mysql_fetch_array($result, $numass));
  mysql_data_seek($result, 0);
    while ($row = mysql_fetch_array($result, $numass)) {
      foreach ($keys as $speckey) {
        $got[$i][$speckey]=$row[$speckey];
      }
    $i++;
    }
  return $got;
}


$conn = mysql_connect($host,$user,$pass);
if (!$conn) {
    die('Could not connect: ' . mysql_error());
};

//Get rodays date
date_default_timezone_set('GMT');
$check_time = date("Y-m-d"); 

mysql_select_db($db, $conn);
mysql_set_charset('utf8',$conn);

$booking_check = mysql_query("SELECT * FROM Booking WHERE Booking_Start LIKE '%$check_time%'");

//if no bookings just echo the entire form but if there is do the else
if (mysql_num_rows($booking_check) == 0) {
    echo '
        <select name="time" id="time">
            <option value="0" selected>(Please Select:)</option>
            <option value="00:00">00:00 - 00:55</option>
            <option value="01:00">01:00 - 01:55</option>
            <option value="02:00">02:00 - 02:55</option>
            <option value="03:00">03:00 - 03:55</option>
            <option value="04:00">04:00 - 04:55</option>
            <option value="05:00">05:00 - 05:55</option>
            <option value="06:00">06:00 - 06:55</option>
            <option value="07:00">07:00 - 07:55</option>
            <option value="08:00">08:00 - 08:55</option>
            <option value="09:00">09:00 - 09:55</option>
            <option value="10:00">10:00 - 10:55</option>
            <option value="11:00">11:00 - 11:55</option>
            <option value="12:00">12:00 - 12:55</option>
            <option value="13:00">13:00 - 13:55</option>
            <option value="14:00">14:00 - 14:55</option>
            <option value="15:00">15:00 - 15:55</option>
            <option value="16:00">16:00 - 16:55</option>
            <option value="17:00">17:00 - 17:55</option>
            <option value="18:00">18:00 - 18:55</option>
            <option value="19:00">19:00 - 19:55</option>
            <option value="20:00">20:00 - 20:55</option>
            <option value="21:00">21:00 - 21:55</option>
            <option value="22:00">22:00 - 22:55</option>
            <option value="23:00">23:00 - 23:55</option>
        </select>
    ';
} else {


    //counter set to 23 because of 0
    $counter = 23;
    $i = 0;

    $booked_times = mysql_fetch_rowsarr($booking_check);
    $num_booked = mysql_num_rows($booking_check);

    echo date("H", strtotime($booked_times[0]['Booking_Start']));
    echo date("H", strtotime($booked_times[1]['Booking_Start']));

    echo "<select name='time' id='time'>";
    echo "<option value='0' selected>(Please Select:)</option>"; 
    while($i<=$counter) {
        //$H is used to compare if the hour slot is booked this adds a 0 to the front of the varible if under 10 for the 24H time format.
        if ($i < 10){
            $H = "0".$i;
        } else {
            $H = $i;
        };

        //Loop through the times that are booked and see if it is the same as the $H which is the current count of the loop so it should set skip to 1 if the time is booked.
        for ($x = 0; $x < $num_booked; $x++){
            if(date("H", strtotime($booked_times[$x-1]['Booking_Start'])) == $H){
                $skip = 1;
            }else{
                $skip = 0;
            };
        };

        if($skip != 1){
            if ($i < 10){
                echo '<option value="0'.$i.':00">0'.$i.':00 - 0'.$i.':55</option>';
                $i++;
            }else{
                echo '<option value='.$i.':00">'.$i.':00 - '.$i.':55</option>';
                $i++;
            };
        } else {
            $i++;
        };
    };
    echo "</select>";
};

But I think its pretty primitive but I am still working on it I think I am getting there I need to cut off all the times before the time actually now.

    I used somthing like this: 

    <?php
function mysql_fetch_rowsarr($result, $numass=MYSQL_BOTH) {
$i=0;
$keys=array_keys(mysql_fetch_array($result, $numass));
mysql_data_seek($result, 0);
while ($row = mysql_fetch_array($result, $numass)) {
  foreach ($keys as $speckey) {
    $got[$i][$speckey]=$row[$speckey];
  }
$i++;
}
 return $got;
}

function convertDate($date){
$date_year=substr($date,1,4);
$date_month=substr($date,6,7);
$date_day=substr($date,8,10);
$date=date("Y-m-d", mktime(0,0,0,$date_month,$date_day,$date_year));
return $date; 
};

$is_ajax = $_REQUEST['is_ajax'];
if (!isset($_POST['date'])) {
echo "<option value='0' selected>Select Date...</option>";
}else{
include 'config.php';
$conn = mysql_connect($host,$user,$pass);
if (!$conn) {
    die('Could not connect: ' . mysql_error());
};

//Get rodays date
date_default_timezone_set('Europe/London');
$date = $_POST['date'];
$check_date = convertDate($date);
$today = date("Y-m-d");
$the_hour = date("H");      

mysql_select_db($db, $conn);
mysql_set_charset('utf8',$conn);

$booking_check = mysql_query("SELECT * FROM Booking WHERE Booking_Start LIKE '%$check_date%'");

//if no bookings just echo the entire form but if there is do the else
if (mysql_num_rows($booking_check) == 0) {
    //counter set to 23 because of 0
    $counter = 23;
    $i = 0;

    if($check_date == $today && $the_hour == 23){
