我通过PHP从SQL表中获取数据以填充HTML表。我就是这样做的：
<table class="posts">
<?php
$respost = mysqli_query($link,"SELECT * FROM table WHERE post_author=$uid LIMIT 16 ");
$row_count=0;
$col_count=0;
while($rowpost = mysqli_fetch_array($respost)) {
if($row_count%4==0){
echo "<tr>";
$col_count=1;
}?>
<td>
<?php
$imageid = $rowpost['thumbnail_link'];
<img src="<?php echo $imageid; ?>" alt="" class="img-responsive" height="220px" height="220px">
<h3><?php echo $rowpost['post_title']; ?></h3>
<h4><?php echo (substr($rowpost['post_excerpt'],0,30)); ?></h4>
<h5><?php echo $rowpost['post_date']; ?></a></h5>
</td>
<?php
if($col_count%4==0){
echo "</tr>";
}
$row_count++;
$col_count++;
}
?>
</table>
现在我要做的是，为此设置一个过滤器。我想添加两个日期选择器，当用户单击“过滤器”按钮时，表格应仅填充在两个给定日期内发布的帖子。
我想过使用日期选择器的表单：
<form name="filter" method="POST" action="team_as.php">
SHOW POSTS FROM:
<input type="date" name="sdate">
<input type="date" name="edate">
<input type="submit" name="submit" value="Filter">
</form>
PHP来处理这些数据：
$edate = $_POST['edate'];
$sdate = $_POST['sdate'];
$filter = "AND $date < post_date > $edate";
我想知道是否有办法在$filter mysql查询中包含此$respost，如下所示：
$respost = mysqli_query($link,"SELECT * FROM table WHERE post_author=$uid $filter LIMIT 16 ");
另请注意，$uid是使用$_GET[]方法从上一页获取的。因此，此页面的链接看起来像www.mysite.com/page?uid=66。所以想知道使用POST和表单过滤是否有效？

一般情况下，如果你进行POST，最好在你的第二种形式中添加uid作为隐藏字段以保留它。也可以在过滤器中使用BETWEEN，因此代码应如下所示：
<form name="filter" method="POST" action="team_as.php">
<input type="hidden" name="uid" value="<?php echo $uid; ?>">
SHOW POSTS FROM:
<input type="date" name="sdate">
<input type="date" name="edate">
<input type="submit" name="submit" value="Filter">
</form>
<?php
if(isset($_POST['submit'])){
$uid = $_POST['uid'];
$edate = $_POST['edate'];
$sdate = $_POST['sdate'];
$filter = "AND DATE(post_date) BETWEEN '$sdate' AND '$edate'";
$query = "SELECT * FROM table WHERE post_author=$uid $filter LIMIT 16 ";
$respost = mysqli_query($link, $query);
}else{
$query = "SELECT * FROM table WHERE post_author=$uid LIMIT 16 ";
$respost = mysqli_query($link, $query);
}
?>
更新：顺便说一下，有一个小表格＆＃39; hack＆＃39;这允许你使用GET和POST vars（使用隐藏字段的内容），但根本不是一个好习惯，所以我不推荐它：
<form name="filter" method="POST" action="team_as.php?uid=<?php echo $uid; ?>">
当您提交此表单时，您将同时分配GET和POST数组，即您将uid作为GET var，其他所有将进入POST数组。

您必须在隐藏字段中添加您的网址值，如此
if(isset($_GET['uid']))
{
$uid=mysqli_real_escape_string($_GET['uid']);
}
<form name="filter" method="POST" action="team_as.php">
SHOW POSTS FROM:
<input type="date" name="sdate">
<input type="date" name="edate">
<input type="hidden" name="uid" value="<?php echo $uid; ?>">
<input type="submit" name="submit" value="Filter">
</form>
您必须为输出查询添加变量
if(isset($_POST['submit']))
{
$uid=mysqli_real_escape_string($_POST['uid']);
$edate = mysqli_real_escape_string($_POST['edate']);
$sdate = mysqli_real_escape_string($_POST['sdate']);
}
$sql="SELECT * FROM table WHERE post_author='$uid'";
if(isset($_POST['submit']))
{
$sql.= " AND $date < post_date > $edate";
}
$respost = mysqli_query($link,$sql);
我认为它解决了你的问题
