[英]HTML table creation in php for a room booking system
I have to create a html table for a room booking system, but i have hit a wall trying to think of ways to insert data into cells.我必须为房间预订系统创建一个 html 表,但我在想办法将数据插入单元格时遇到了麻烦。 At the moment i am getting data from a database (start time and end time for the booking).
目前我正在从数据库中获取数据(预订的开始时间和结束时间)。 I then loop through the times from an array and use an if statement to compare the start time to the time in the time array.
然后我循环遍历数组中的时间并使用 if 语句将开始时间与时间数组中的时间进行比较。
This is what i have at the moment : Room booking image这就是我目前所拥有的:房间预订图片
The main problem that i am having is that in my database if there are two bookings on the same day it will only show that last one in the array.我遇到的主要问题是,在我的数据库中,如果同一天有两个预订,它只会显示数组中的最后一个。
$tableStart = "<table class='table_main'><thead><tr id='table_first' class='first_last'><th class='first_last'>Time:</th>";
$tableMid = "</tr></thead><tbody>";
$tableEnd = "</tbody></table>";
foreach ($newBookings as $booking) {
$tableStart .= "<th class='first_last'>$booking[0]</th>";
}
foreach ($times as $time) {
$tableMid .= "<tr class='even_row'><td class='time'>{$time['times']}</td>";
$i = 0;
foreach ($newBookings as $booking) {
unset($booking[0]);
$x = count($booking);
if ($x > 0) {
if ($booking[$i]['start_Time'] == $time['times']) {
$tableMid .= "<td class='new'>{$booking[$i]['start_Time']}</td>";
} else if($booking[$i]['end_Time'] == $time['times']) {
$tableMid .= "<td class='new'>{$booking[$i]['end_Time']}</td>";
} else {
$tableMid .= "<td class='new'></td>";
}
} else {
$tableMid .= "<td class='new'></td>";
}
++$i;
}
}
$tableStart .= $tableMid;
$tableStart .= $tableEnd;
return $tableStart;`
The way i have my data set up at the moment in the arrays currently look like this:我目前在数组中设置数据的方式目前如下所示:
$times = [
0 => ['06:00'],
1 => ['06:30'],
2 => ['07:00'],
3 => ['07:30'],
4 => ['08:00'],
5 => ['08:30'],
6 => ['09:00'],
7 => ['09:30'],
8 => ['10:00'],
9 => ['10:30'],
10 => ['11:00'],
11=> ['11:30'],
12 => ['12:00'],
13 => ['12:30'],
14 => ['13:00'],
15 => ['13:30'],
16 => ['14:00'],
17 => ['14:30'],
18 => ['15:00'],
19 => ['15:30'],
20 => ['16:00'],
21 => ['16:30'],
22 => ['17:00'],
23 => ['17:30'],
24 => ['18:00'],];
$newBookings = [
0 => [
0 => 'Room 33'
],
1 => [
0 => 'New room 8',
1 => [
'room_Name' => 'New room 8',
'start_Time' => '11:30',
'end_Time' => '12:30'
]
],
2 => [
0 => 'sds',
1 => [
'room_Name' => 'sds',
'start_Time' => '09:30',
'end_Time' => '11:30'
],
2 => [
'room_Name' => 'sds',
'start_Time' => '14:30',
'end_Time' => '16:30'
]
],
3 => [
0 => 'New Room 3'
],
4 => [
0 => 'NewRoom5'
],
5 => [
0 => 'New room 55'
]
];
I apologise if i have left anything out or am too vague with my description.如果我遗漏了任何内容或我的描述过于含糊,我深表歉意。 Thank you
谢谢
For anyone who sees this i found a fix, i used ADyson's recommendation for the array and reworked my code so that it now works correctly.对于看到这一点的任何人,我找到了一个修复程序,我使用了 ADyson 对阵列的建议并重新编写了我的代码,以便它现在可以正常工作。 For anyone interested here is the code i used :
对于任何对此感兴趣的人,我使用的代码是:
public function render(): string
{
$data = $this->tableData; //from abstract class contains table data
$times = $this->tableTimes; //gets times
$rooms = $this->roomNames; //gets room names
$startTime = $times[0]['start_time']; //sets the start time
$endTime = $times[0]['end_time']; // sets the end time
$times = $this->setTimeArray($startTime, $endTime); //goes to function
$newBookings = $this->setDataArray($data, $rooms); // goes to function
$tableStart = "<table class='table_main'><thead><tr id='table_first' class='first_last'><th class='first_last'>Room:</th>";
$tableMid = "</tr></thead><tbody>";
$tableEnd = "</tbody></table>";
foreach ($times as $key => $time) {
$tableStart .= "<th class='first_last'>{$time}</th>";
}
foreach ($newBookings as $booking) {
$tableMid .= "<tr class='even_row'><td class='room_Name'>{$booking['Room']}</td>";
$x = 0;
$e = 0;
foreach ($times as $time) {
if ($x == count($booking['Bookings'])) {
$x = 0;
}
if ($e == count($booking['Bookings'])) {
$e = 0;
}
if (count($booking['Bookings']) < 1) {
$tableMid .= "<td class='new'></td>";
} else if ($booking['Bookings'][$x]['start_Time'] == $time) {
$tableMid .= "<td class='room_Booked'>{$booking['Bookings'][$x]['start_Time']}</td>";
$x++;
} else if ($booking['Bookings'][$e]['end_Time'] == $time) {
$tableMid .= "<td class='room_Booked'>{$booking['Bookings'][$e]['end_Time']}</td>";
$e++;
} else {
$tableMid .= "<td class='new'></td>";
}
}
}
$tableStart .= $tableMid;
$tableStart .= $tableEnd;
return $tableStart;
}
Setting the times to an array将时间设置为数组
public function setTimeArray($startTime, $endTime)
{
$i = 0;
$endTimes = strtotime($endTime);
$endTime = date("H:i", strtotime('+30 minutes', $endTimes));
do {
$times[$i] = $startTime;
$time = strtotime($startTime);
$startTime = date("H:i", strtotime('+30 minutes', $time));
$i++;
} while ($startTime != $endTime);
return ($times);
}
Putting room booking data into one array将房间预订数据放入一个数组
public function setDataArray($data, $rooms)
{
$newBookings = [];
$x = 0;
foreach ($rooms as $key) {
$newBookings[$x] = array(
'Room' => $key['room_name'], 'Bookings' => []
);
$y = 0;
foreach ($data as $value) {
if ($value['room_name'] == $newBookings[$x]['Room']) {
$newBookings[$x]['Bookings'][$y] = [
'room_Name' => $value['room_name'],
'start_Time' => $value['requested_time'],
'end_Time' => $value['requested_time_end']
];
$y++;
}
}
$x++;
}
return ($newBookings);
}
