Question

基本上，我正在创建一个事件日历，其中在事件输入数据库的那一天生成了提交按钮。点击提交按钮后，它会打开一个新页面（events.php），显示当天活动的详细信息。

但是，我的问题是我不知道如何将日历（月份的日期）提交按钮的日期输入到从我的数据库获取数据的查询中。目前我只是硬编码了一个日期，看它是否有效。

如果我不清楚我很高兴再次讨论它，但它必须是动态的，所以它可以在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>';
echo '<div class="next_month"><input name="button" type="submit" value="Next Month" onClick="javascript:next_month();"></div>';
echo '</div>';

echo '<div class="week_days">';
echo '<div class="days_of_the_week">Sun</div>';
echo '<div class="days_of_the_week">Mon</div>';
echo '<div class="days_of_the_week">Tues</div>';
echo '<div class="days_of_the_week">Wed</div>';
echo '<div class="days_of_the_week">Thur</div>';
echo '<div class="days_of_the_week">Fri</div>';
echo '<div class="days_of_the_week">Sat</div>';
echo '<div class="clear"></div>';
echo '</div>';


if ($pre_days != 0) { 
    for($i=1; $i<=$pre_days; $i++) {
        echo '<div class="non_cal_day"></div>';
    }
}
$con=mysql_connect("localhost","pytsuemg_brodie","brodie");
mysql_select_db("pytsuemg_brodie", $con);

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

    $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 class="cal_day">';
    echo '<div class="day_heading">' . $i . '</div>';
    if($num_rows > 0) 
        { 
        echo "<input type=\"submit\"value=\"View Event\" onClick=\"window.open('events.php')\">";
        }
    echo '</div>';



} //end of for loop

if ($post_days !=0) {
    for($i=1; $i<=$post_days; $i++) {
        echo '<div class="non_cal_day"></div>';
    }
}

echo '</div>';

?>

Events.php（从数据库中获取信息）

<?php
    $con=mysqli_connect("localhost","pytsuemg_brodie","brodie","pytsuemg_brodie");



    $query=("SELECT DateStart, description FROM Events WHERE DateStart = '2/2/2014'");
    $num_rows = 0;
    // check if the query returns anything
    $result = mysqli_query($con,$query) or die(mysql_error());

    if ($result)
    {

        $num_rows = mysqli_num_rows($result);
    }

    if($num_rows > 0) {
            while ($newArray = mysqli_fetch_array($result)) {
                $evdate = $newArray['DateStart'];
                $description = $newArray['description'];
                echo "The Date is $evdate and the description is $description <br>";
            }

    }
?>

我不确定这是你想要的，但我认为就是这样：

     <input type=\"button\"value=\"View Event\" onClick=\"window.open('events.php?date=".$date."')\">

然后在events.php

     $date=mysqli_real_escape_string($con, $_GET['date']);
     $query=("SELECT DateStart, description FROM Events WHERE DateStart = '$date'");
