Question

对于我正在创建的系统，我正在尝试生成搜索页面。它有以下HTML：

 <?php include 'includes/header.php';
 ?>
 <fieldset>
 <legend>Edit all Entries</legend>
 <form action="editall.php" method="POST">
 <p><label for="mhost">Meeting Host</label><input type="text" name="mhost" id="mhost"></p>
 <p><label for="vname">Visitor Name</label><input type="text" name="vname" id="vname"></p>
 <p><label for="datepicker">Meeting Date</label><input type="text" name="datepicker" id="datepicker"></p>
 <p><input type="submit" name="submit"></p>
 </form>
 </fieldset>
 <?php if(isset($_POST["submit"])==TRUE)
 {
      $datepicker = trim($_POST["datepicker"]);
      if(empty($datepicker)==FALSE)
      {
           $datepicker = explode("/", $datepicker);
           $datepicker = "{$datepicker[2]}-{$datepicker[1]}-{$datepicker[0]}";
      }
      $mhost = htmlentities(trim($_POST["mhost"]));
      $vname = htmlentities(trim($_POST["vname"]));     
      $db_search = search_database($mhost, $vname, $datepicker, $connection);
      if($db_search==FALSE)
      {
           echo "<div class=\"centered_text\">Nothing found matching search</div>\n";
      }
      else
      {
           echo "<table>\n
           <thead>\n
           <tr>\n
           <th>Date</th>\n
           <th>Time</th>\n
           <th>Visitor(s)</th>\n
           <th>Company</th>\n
           <th>Host</th>\n
           <th>Room</th>\n
           <th></th>\n
           </tr>\n
           </thead>\n
           <tbody>\n";
           /* This will hold the number of meetings */
           foreach($db_search as $meeting)
           {
                $visitor_names = stripslashes($meeting["visitor_names"]);
                $company_name = stripslashes($meeting["company_name"]);
                $meeting_host = stripslashes($meeting["meeting_host"]);
                $meeting_id = (int)$meeting["meeting_id"];
                $start = date("g:ia", strtotime($meeting["meeting_start"]));
                $date = date("d/m/y", strtotime($meeting["meeting_start"]));
                $meeting_location = stripslashes($meeting["meeting_location"]);
                echo "<tr>\n";
                echo "<td>{$date}</td>\n";
                echo "<td>{$start}</td>\n";
                echo "<td>{$visitor_names}</td>\n";
                echo "<td>{$company_name}</td>\n";
                echo "<td>{$meeting_host}</td>\n";
                echo "<td>{$meeting_location}</td>\n";
                echo "<td><a href=\"edit.php?id={$meeting_id}\">Edit</a></td>\n";
                echo "</tr>\n";
           }     
           echo "</tbody>\n";
           echo "</table>\n";
      }
 }
 include 'includes/footer.php';
 ?>

我查询数据库的函数如下：

 function search_database($mhost, $vname, $datepicker, $connection)
 {
      $mhost = $connection->real_escape_string($mhost);
      $mhost = $connection->real_escape_string($vname);
      $query_search = $connection->query("SELECT `meeting_id`, `visitor_names`, `meeting_host`, `email_address`, `company_name`, DATE_FORMAT(`meeting_start`, '%Y-%m-%d') AS `meeting_start`, `meeting_location`, `host_extension` FROM `details` WHERE (`meeting_host` LIKE '%{$mhost}%' OR `visitor_names` LIKE '%{$vname}%' OR `meeting_start` = '{$datepicker}') AND (`visibility` = 0) ORDER BY `meeting_start` ASC");
      if($connection->error)
      {
           return $connection->error;
      }
      if($query_search->num_rows > 0)
      {
           $results = array();
           while($rows = $query_search->fetch_assoc())
           {
                $results[] = $rows;
           }
           return $results;
      }
      else
      {
           return FALSE;
      }
 }

问题在于，虽然如果您输入主机名或访客名称，但如果我输入日期，它就无法正常工作。当输入日期时，它将返回所有日期。我不知道问题是什么，请你帮忙

无法添加评论以寻求澄清（低代表），但MySQL的默认日期格式为YYYY-MM-DD，它不是100％清除您的帖子中的日期您正在格式化正确的格式。如果您使用美国日期，您的MM / DD / YYYY将被转换为YYYY-DD-MM，这将是无效的。

$datepicker = "{$datepicker[2]}-{$datepicker[1]}-{$datepicker[0]}";

因此，如果您使用美国日期，则需要使用：

$datepicker = "{$datepicker[2]}-{$datepicker[0]}-{$datepicker[1]}";

PHP：似乎无法使用MySQL查询日期
