无法从数据库中检索数据

Question

这里是脚本，如果我选择日期然后我从数据库中获取数据。但如果我选择任何日期，那么我无法从日历中选择日期的数据库中获取任何数据。有人可以修吗？

<script language="JavaScript" type="text/javascript" src="calendar/calendar.js"></script>
<script src="jquery.js"></script>
<script>
$(document).ready(function()
{
//ajaxTime.php is called every second to get time from server
var refreshId = setInterval(function()
{
 $('#timeval').load('ajaxTime.php?randval='+ Math.random());
}, 1000);

//stop the clock when this button is clicked
$("#stop").click(function()
{
 clearInterval(refreshId);
});
});
</script>
<!--<strong><div align="right" id="timeval" style="color:#FF6600; font-family:Arial, Helvetica, sans-serif">--:--:--</div></strong>--> 
        <table width="420" border="1" >
        <form name="showdraw" action="ooo.php" method="post">
        <tr  bgcolor="#FF6600">
                <td><script> DateInput('cdate', true, 'YYYY-MM-DD'); </script></td>
                <td> <input type="submit" value ="Show"> <input type="hidden" value="Show" name="d1"> </td>
        </tr>
        <tr  bgcolor="#FF6600">
            <td><font color=#2F4F4F><h2>Draw Time</h2></font></td>
            <td><font color=#2F4F4F><h2>Wining Number</h2></font></td>
          </tr>
        </form>
<tbody>
<?php
include('connect.php');
if (isset($_GET["d1"])) { $d1= $_GET["d1"]; } else { $d1=('YYYY-MM-DD'); }; 
$result = $db->prepare("SELECT * FROM birthday WHERE date = :a");
$result->bindParam(':a', $d1);
$result->execute();
for($i=0; $row = $result->fetch(); $i++){
?>
<tr class="record">
            <tr  bgcolor="#EEF3E2">
<td><font size=5><font color='#008B00'><?php echo $row['dt']; ?></font></td>
<td><font size=5><font color='#008B00'><?php echo $row['wn']; ?></font></td>
<?php
}
?>

好的，这里有一大段代码，从表单标签开始。我不知道你为什么一直把隐藏的输入放回去。您不需要它，只要日历输入称为 d1。如果您添加第二个具有相同名称的输入，您将消除正确的值，并且您将永远无法从日历输入中获取日期。

    <form name="showdraw" action="ooo.php" method="post">
    <tr bgcolor="#FF6600">
            <td><script> DateInput('cdate', true, 'YYYY-MM-DD'); </script></td>
            <td> <input type="submit" value ="Show"> </td>
    </tr>
    <tr bgcolor="#FF6600">
        <td><font color="#2F4F4F"><h2>Draw Time</h2></font></td>
        <td><font color="#2F4F4F"><h2>Wining Number</h2></font></td>
      </tr>
    </form>
    <tbody>

<?php
include('connect.php');

if (isset($_GET["d1"])) { 
    $d1= $_GET["d1"]; 
} else { 
    $d1=date('YYYY-MM-DD'); 
}

$result = $db->prepare("SELECT * FROM birthday WHERE date = :a");
$result->bindParam(':a', $d1);
$result->execute();

while($row = $result->fetchAll()){
?>

<tr class="record">
    <tr  bgcolor="#EEF3E2">
    <td><font size="5"><font color="#008B00"><?php echo $row['dt']; ?></font></td>
    <td><font size="5"><font color="#008B00"><?php echo $row['wn']; ?></font></td>
    </tr>

<?php  }   ?>

    </tbody>
    </table>
