Question

我正在尝试从数据库中检索数据。我正在使用下面的代码： -

<?php
  include('header.php'); //Header which contains html, head, etc 
  include('function/dbconnect.php'); //Database connection
?>

<!-- menu bar here -->

        <form method="post" class="form">

        <?php           
            $month          = mysql_real_escape_string($_POST['month']);

            $section        = mysql_real_escape_string($_POST['section']);
            $reporter       = mysql_real_escape_string($_POST['reporter']);
            $location       = mysql_real_escape_string($_POST['location']);
            $incident_date = mysql_real_escape_string($_POST['incident_date']);
            $incident_time = mysql_real_escape_string($_POST['incident_time']);
            $description    = mysql_real_escape_string($_POST['m_description']);
            $priority       = mysql_real_escape_string($_POST['priority']);
            $received_date = mysql_real_escape_string($_POST['received_date']);
            $received_time = mysql_real_escape_string($_POST['received_time']);
            $issued_to  = mysql_real_escape_string($_POST['issued_to']);
            $completed_date = mysql_real_escape_string($_POST['completed_date']);   
            $completed_time = mysql_real_escape_string($_POST['completed_time']);   
            $incident_reason= mysql_real_escape_string($_POST['incident_reason']);  
            $m_status = mysql_real_escape_string($_POST['m_status']);

            $query = mysql_query("SELECT *, (DATE_FORMAT(DATE(incident_date),'%m/%Y')) AS month
                                  FROM tbl_maintenance_form

            $sql = mysql_query("SELECT DISTINCT(DATE_FORMAT(DATE(incident_date),'%m/%Y')) AS month
                                FROM tbl_maintenance_form
                                ORDER BY DATE_FORMAT(DATE(incident_date),'%Y'), DATE_FORMAT(DATE(incident_date),'%m')
                                ASC");

首先，它没有返回任何错误，它显示我想要的完美。不知何故，在构建系统的过程中，我得到布尔错误。那时我意识到$query中存在一些错误。因此，我从WHERE DATE_FORMAT(DATE(incident_date),'%m-%Y') LIKE '%" . $incident_date . "%' or die('Could not get data: ' . mysql_error())删除了$query。但是，系统无法检索月份。

我正在尝试做什么/我的愿望输出如下： -

我错过了月份列 - 列中的值= events_date的月份列表。

假设有下拉列表根据所选月份显示数据，但没有什么可以选择的。下拉列表中的值= incident_date的月份年份的不同列表。

如何检索和显示数据并制作显示月份和年份的下拉列表。？

如何检索数据和下拉列表月份
