Question

我有一个数据表，我正在尝试根据日期添加搜索功能，但我无法得到结果在这里是我的代码：

<form action="search.php" id="searchform" method="POST" class="searchbox-container">
<input type="text" id="searchbox" placeholder="Search" name="searchbox" class="searchbox" />
    <input type="datetime-local" name="date">
    <select name="select" id="select">
    <option value="type">Type</option>
    <option value="name">Name</option>
</select>
    <input type="submit" name="search" class="searchbox-btn" value="Go" />

 </form>

 <?php

此处连接：

$date=$_POST['date'];


         if($_POST['select']=="type"){
        $sqlcommand="SELECT * FROM eventform WHERE event_type LIKE '%$search%'";    


        }
        elseif($_POST['select']=="name"){
        $sqlcommand="SELECT * FROM eventform WHERE event_name LIKE '%$search%'";        


        }
        else {
            if($date!=0)
              $sqlcommand="SELECT * FROM eventform WHERE start_date LIKE '$date'";  


        }
          $sqldata=mysqli_query($con,$sqlcommand)
          or die("Error Getting Data");

          $count=mysqli_num_rows($sqldata);
          if($count!=0){

                  echo "<table border=2 bordercolor=#440000 cellpadding=2 bgcolor=#DDDDDD width=100%>";
            echo "<tr bgcolor=#555555 style=font-size:18px align=center><th>Event Code</th><th>Event Name</th><th>Event Type</th><th>Event Level</th><th>Start Date</th>
      <th>End Date</th><th>Point</th><th>Picture</th><th>Video</th><th>Description</th></tr>";
            while($row=mysqli_fetch_array($sqldata)){
            echo "<tr align=center><td>";
              echo $row['event_code'];

              echo "</td><td>";
              echo $row['event_name'];
              echo "</td><td>";

              echo $row['event_type'];
              echo "</td><td>";

              echo $row['event_level'];
              echo "</td><td>";

              echo $row['start_date'];
              echo "</td><td>";

              echo $row['end_date'];
              echo "</td><td>";

              echo $row['points'];
              echo "</td><td>";

              echo $row['pic'];
              echo "</td><td>";

              echo $row['video'];
              echo "</td><td>";

              echo $row['description'];
              echo "</td></tr>";

              }
  echo "</table>";

当我根据事件的类型和名称进行搜索时，我得到了结果，但是当我想根据日期和时间进行搜索时，它只是不起作用。

您的日期字段的格式是时间戳？对于时间戳，请执行：

$sqlcommand="SELECT * FROM eventform WHERE start_date > '".$date."' ORDER BY start_date DESC";

或日期yy-mm-dd格式，只需：

$sqlcommand="SELECT * FROM eventform WHERE start_date = '".$date."' ORDER BY start_date DESC";

根据日期在数据表中搜索功能
