【问题描述】：
基本上，我正在制作一个事件日历，其中在将事件输入我的数据库的那一天生成一个提交按钮。点击提交按钮会打开一个新页面（events.php），显示当天事件的详细信息。
但是，我的问题是我不知道如何将日历上的提交按钮所在的日期（当月的某一天）获取到从我的数据库中获取数据的查询中。目前我刚刚硬编码了一个日期，看看它是否有效。
如果我不清楚，我很乐意再看一遍，但它必须是动态的，以便它可以在任何一年任何一个月的任何一天工作
代码： Calendar_start.php（创建日历）
?php
$showmonth = $_POST['showmonth'];
$showyear = $_POST['showyear'];
$showmonth= preg_replace('#[^0-9]#i', '', $showmonth);
$showyear= preg_replace('#[^0-9]#i', '', $showyear);
$day_count = cal_days_in_month(CAL_GREGORIAN, $showmonth, $showyear);
$pre_days = date('w', mktime(0,0,0, $showmonth, 1, $showyear));
$post_days = (6-(date('w', mktime(0,0,0, $showmonth, $day_count, $showyear))));
echo '<div id="calendar_wrap">';
echo '<div class="title_bar">';
echo '<div class="previous_month"><input name="button" type="submit" value="Previous Month" onClick="javascript:last_month();"></div>';
echo '<div class="show_month">' . date('F', mktime(0, 0, 0, $showmonth)) . ' ' . $showyear . '</div>';

$date = $i.'/'.$showmonth.'/'.$showyear;
//echo $date;
$query = "Select EventId FROM Events WHERE DateStart = '$date'";
$num_rows = 0;
// check if the query returns anything
$result = mysql_query($query,$con) or die(mysql_error());
if ($result)
{
$num_rows = mysql_num_rows($result);
}

}
echo '</div>';
} //end of for loop

for($i=1; $i<=$post_days; $i++) {

}
}

-
任何人，我真的需要帮助
-
缩小你的问题。任何事情都与 PHP、jQuery 和 MySQL 相关联是不可能的 - 一次。
-
此外，发布大量源代码通常不会带来更好的答案。问题应该是一般性的，以便答案对其他人也有用。
-
提交按钮 ->
... onClick=\"window.open('events.php?date=$date')然后$date = mysqli_real_escape_string($con,$_GET['date']); $query=("SELECT DateStart, description FROM Events WHERE DateStart = '$date'");在你的events.php?
