Php 删除一行后进入同一数据页

我有一个表，其中显示了特定日期的行数。我想在删除一行之后，返回到同一页并显示相同日期的相同行。示例：如果我在2015年6月6日有两行，并且删除了其中一行，我希望返回到同一页并查看另一行。我有以下代码：

Delete.php：

<?php 
require_once ('../include/global.php');
$id=$_REQUEST['id'];
$sql = "DELETE FROM appoint WHERE id=".$id;
$result=mysqli_query($con,$sql) or die('Unable to execute query. '. mysqli_error($con));
if($result){
    $sql2 = "SELECT date FROM appoint WHERE id=".$id;
    $result2=mysqli_query($con,$sql2) or die('Unable to execute query. '. mysqli_error($con)); 
    $rows = mysqli_fetch_array($con, $result2);
    header("location:appoint.php");


}
else { 
header("location:../update/update_false.php");
}
?>

getdata.php：

<?php
require_once ('../include/global.php');
    if($_POST['seldate']) {
        $selDate = $_POST['seldate'];
        $sql="SELECT * FROM clinic.appoint WHERE date='$selDate'";
        $result = mysqli_query($con, $sql) or die($sql."<br/><br/>".mysql_error());
        while($rows=mysqli_fetch_array($result)){
    ?>
<tr>
    <td scope="row"><?php echo $rows['time'] ?></td>
    <td scope="row"><?php echo $rows['name'] ?></td>
    <td scope="row"><?php echo $rows['date'] ?></td>
    <td scope="row"><form action='/clinic form/appoint/delete.php'=<?php echo $rows['id']; ?>' method="post">
        <input type="hidden" name="id" value="<?php echo $rows['id']; ?>">
        <input type="submit" name="submit1" value="Done">
    </form>

    </td>
    </tr>
<?php } } ?>

只是一个简单的解决方案：将ajax部件放入函数中

更改要删除的PHP代码：

require_once ('../include/global.php');
$id = $_REQUEST['id'];

# Find the date for which you are deleting...
$query = "SELECT date FROM appoint WHERE id = " . $id;
$row = mysqli_fetch_assoc(mysqli_query($con, $query));
$request_date = $row['date'];

$sql = "DELETE FROM appoint WHERE id=".$id;
$result = mysqli_query($con,$sql) or die('Unable to execute query. '. mysqli_error($con));
if($result){
    header("Location: appoint.php?date=" . $request_date);
}
else { 
    header("Location: ../update/update_false.php");
}

现在，当您从delete返回时，您有一个
$\u GET['date']
。但是，当你第一次加载页面时，你没有这个功能

现在改变你的JS来适应它。将AJAX部分放入函数中

$(document).ready(function(){
    $("#Date").change(function(){
        var seldate =$(this).val();
        display_data(seldate);
    });

    // This is the function...
    function display_data(seldate) {

        $("#scheduleDate").html(seldate);
        var dataString = 'seldate='+ seldate;
            $.ajax({
            type: "POST",
            url: "getdata.php",
            data: dataString,
            cache: false,
            success: function(data) {
                $("#Schedule").html(data);
            } 
        });

    }

    // Now here is the real code for retaining your Date...
    <?php
    if (!empty($_GET['date'])) {
        ?>
    display_data('<?php echo $_GET["date"]; ?>')
        <?php
    }
    ?>
    document.getElementById('Date').value = '<?php echo @$_GET["date"]; ?>';

});

并将重定向部分更改回代码

header("Location: appoint.php");

现在更改我的脚本块的这一部分：

发件人：


显示_数据（“”）；
document.getElementById（'Date'）。值=''；

致：


显示_数据（“”）；
document.getElementById（'Date'）。值=''；

使用会话的优点是，如果您的删除失败，并且被重定向到更新失败页面。之后，当您再次回到列表页面时。您将位于该列表的左侧。
对于Ajax调用后的From post，无法检索您首先使用Ajax方法获取的数据，因此您需要另一种Ajax方法从数据库中删除记录

先换这个

<form action='/clinic form/appoint/delete.php'=<?php echo $rows['id']; ?>' method="post">
    <input type="hidden" name="id" value="<?php echo $rows['id']; ?>">
    <input type="submit" name="submit1" value="Done">
</form>

然后在同一个
getdata.php
中，您有
向其添加一个类
，最后您有
进行以下更改，并在其中放置一个delete Ajax方法调用，这样当您从数据库中获取记录时，delete Ajax方法调用将与数据一起加载，并准备好DOM

<?php } ?>
    <script>
    $(document).ready(function(){
        $(".DelMe").on('click', function(){
                var DelId =$(this).data('id');     
                var dataString = 'DelId='+ DelId;
                    $.ajax({
                    type: "POST",
                    url: "delete.php",
                    data: dataString,
                    cache: false,
                    success: function(msg) {
                        $(this).parents(".deleted").hide(500);
                    } 
                });
            });
    });
    </script>
<?php } ?>

现在创建新的PHP文件并将其命名为
delete.PHP

<?php require_once ('../include/global.php');
    if($_POST['DelId']) {
        $DelId = $_POST['DelId'];
        $sql="DELETE FROM appoint WHERE id='$DelId'";
        $result = mysqli_query($con, $sql) or die($sql."<br/><br/>".mysql_error());
        $rowcount=mysqli_num_rows($result);
        if ($rowcount > 0) {
            echo "success";
        } else {
            echo "false";
        }   
    } 
?>

我将在一小时后尝试，并将回复您
<?php
if (!empty($_SESSION['date'])) {
    ?>
    display_data('<?php echo $_SESSION["date"]; ?>');
    <?php
    unset($_SESSION['date']);
}
?>
document.getElementById('Date').value = '<?php echo @$_SESSION["date"]; ?>';
