Question

我制作了一个有效的PHP事件日历，我可以在几个月之间切换，但是当我在我的数据库中添加一个事件时，它并没有出现在我的日历上。任何最感谢的帮助。

代码： show calendar.php

<html>
<head>
<link href="calstyle.css" rel="stylesheet" type="text/css" media="all" />
<script language="JavaScript" type="text/javascript">
function initialCalendar(){
    var hr = new XMLHttpRequest();
    var url = "calendar_start.php";
    var currentTime = new Date ();
    var month = currentTime.getMonth() + 1;
    var year = currentTime.getFullYear();
    showmonth = month;
    showyear = year;
    var vars= "showmonth="+showmonth+"&showyear="+showyear;
    hr.open("POST", url, true);
    hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    hr.onreadystatechange = function() {
        if (hr.readyState == 4 && hr.status == 200) {
            var return_data = hr.responseText;
                document.getElementById("showCalendar").innerHTML = return_data;
        }
    }
    hr.send(vars);
    document.getElementById("showCalendar"). innerHTML = "processing...";
}
</script>
<script language="JavaScript" type="text/javascript">

    var nextmonth = showmonth + 1;

events.php

<?php

include ("connect.php");

    while($row= mysql_fetch_array($query)) {
        $desc = $row['description'];
        $events .='<div id="eventsBody"> . $desc .'<br /><hr><br /></div>';
    }
}
echo $events;
?>

connect.php

<?php
$con=mysqli_connect("localhost","root","","Familease");
if (mysqli_connect_errno($con))
   {
   echo "Failed to connect to MySQL: " . mysqli_connect_error();
   }
 ?>

另外一张样式表应该可以正常工作。对于大规模代码转储

抱歉

Answer 1

以下代码显示了一些语法错误

while($row= mysql_fetch_array($query)) {
        $desc = $row['description'];
        $events .='<div id="eventsBody"> . $desc .'<br /><hr><br /></div>';
    }

应该是

while($row= mysql_fetch_array($query)) {
        $desc = $row['description'];
        $events .='<div id="eventsBody">'.$desc .'<br /><hr><br /></div>';
    }

事件不会出现在php日历上
