我选择下拉列表并且没有填充。我不知道为什么？我是php的新手，所以非常感谢任何帮助。

这是我的代码：

<section id="content" class="planner">  
<select id="month" name="month">                      
  <option value="0">--Select Month--</option>
  <option value="January">January</option>
  <option value="Februrary">February</option>
  <option value="March">March</option>
  <option value="April">April</option>
  <option value="May">May</option>
  <option value="June">June</option>
  <option value="July">July</option>
  <option value="August">August</option>
  <option value="September">September</option>
  <option value="October">October</option>
  <option value="November">November</option>
  <option value="December">December</option>
</select>

<select id="year" name="year">                      
  <option value="0">--Select Year--</option>
  <option value="2010">2010</option>
  <option value="2011">2011</option>
  <option value="2012">2012</option>
  <option value="2012">2013</option>
  <option value="2012">2014</option>
  <option value="2012">2015</option>
  <option value="2012">2016</option>
</select>

<table class="month">
    <tr class="days">
        <td>Mon</td>
        <td>Tues</td>
        <td>Wed</td>
        <td>Thurs</td>
        <td>Fri</td>
        <td>Sat</td>
        <td>Sun</td>
    </tr>
<?php 

        if($_POST['month'] && $_POST['year'] != 0)
        {
           $today = date("d"); // Current day
           $month=$_POST['month'];
           $year=$_POST['year'];
           GenerateCalendar($today,$month,$year);
        }

        function GenerateCalendar($today,$month,$year)
        {
            $today = date("d"); // Current day
            $days = cal_days_in_month(CAL_GREGORIAN,$month,$year); // Days in current month

            $lastmonth = date("t", mktime(0,0,0,$month-1,1,$year)); // Days in previous month

            $start = date("N", mktime(0,0,0,$month,1,$year)); // Starting day of current month
            $finish = date("N", mktime(0,0,0,$month,$days,$year)); // Finishing day of  current month
            $laststart = $start - 1; // Days of previous month in calander

            $counter = 1;
            $nextMonthCounter = 1;

            if($start > 5){ $rows = 6; }else {$rows = 5; }

            for($i = 1; $i <= $rows; $i++){
                    echo '<tr class="week">';
                    for($x = 1; $x <= 7; $x++){             

                            if(($counter - $start) < 0){
                                    $date = (($lastmonth - $laststart) + $counter);
                                    $class = 'class="blur"';
                            }else if(($counter - $start) >= $days){
                                    $date = ($nextMonthCounter);
                                    $nextMonthCounter++;

                                    $class = 'class="blur"';

                            }else {

            }

您缺少select语句周围的html <form>标记。您还需要提交输入类型以发送表单

<form action="" method="POST" name="myForm">
    <!--YOUR SELECTS-->
    <input type="submit" value="SEND THIS FORM"/>
</form>

表单操作“”将发布数据发送到您当前的页面。 POST或GET方法。您正在使用POST。

这就是全部。在继续使用php之前，你应该考虑学习HTML基础知识。

为什么这个PHP代码在年份和月份没有显示我的日历？
