我在这里只是遇到if / else或一些逻辑问题的问题,我有一个全日历显示所有保留日期,我将每个日期的保留限制为5,但是当我保留2个或更多时日期,并保留其他日期,它给我的结果与4相同。
global $db;
$data = array();
$query = "SELECT * FROM reserve_master
INNER JOIN reserve_details
on reserve_master.reserve_id = reserve_details.reserve_id
INNER JOIN reserve_indicator
on reserve_master.reserve_id = reserve_indicator.reserve_id
WHERE reserve_indicator.touserid = '$id'
AND reserve_master.type = 'Repair' ";
$res = mysqli_query($db,$query);
$count = mysqli_num_rows($res);
$count = 5 - $count;//count the available slot
$date_changed = "";
$reserve_id = 0;
foreach ($res as $row)
{
date_default_timezone_set('Asia/Manila');
$current_timestamp = strtotime($row["dateend"] . '+1 day');
$time = date("Y/m/d",$current_timestamp);
if($row["datestart"] == $date_changed)
{
//This is for avoiding repeating graph on fullcalendar
}
else
{
if(empty($count))
{
$count = '0';
}
else
{
$count;
}
$data[] = array(
'id' => $row["reserve_id"],
'title' => $count,
'start' => $row["datestart"],
'end' => $time,
'color' =>getColor($row["status"])
);
$date_changed = $row["datestart"];
$reserve_id = $row["reserve_id"];
}
}
echo json_encode($data);

我所尝试的只是在2018年2月2日获得可用的版本,而不是其他版本。
答案 0 :(得分:0)
代码很乱,很抱歉;
问题已经解决;
我在fullcalendar上使用eventLimit并将其设置为1
Count = 5,不减去num_rows
很少在if语句上设置
很少回答我使用行和res,因为它易于指示结果和行,并且与其他查询一样使用。
谢谢。
