Question

以下是发生的事情：

用户使用复选框选择日期并将信息提交到MYSQL数据库以存储并显示在表格中。
数据库更新，但网页上的表格没有更新。您需要刷新页面并被询问＆＃34;您确定要再次发送表单吗？取消/发送＆＃34;

<?php require_once("./includes/session.php"); ?>
<?php require_once("./includes/db_connection.php"); ?>
<?php require_once("./includes/functions.php"); ?>
<?php include("./includes/layouts/header.php"); ?>

    <div class="wrapper">
        <?php table_date(); ?>
        <div id="current_wk_head" >
            <?php current_table(); ?>
        </div>
    </div> 

    <div class="wrapper">
        <h4 id="directions">Put a check-mark by the days you want to play!</h4>
        <form name="input" action="wk1.php" method="post">
        <?php week1_changes(); ?>

        <div id="submit_section">
            <input type="submit" name="playdaz" value="SUBMIT" class="button">

            <form name="input" action="wk1.php" method="post">
                <input type="submit" name="goback" value="BACK" class="button">
            </form>
        <p> When you click SUBMIT all days are submitted so, each day should be appropriately checked.</p>
        <p> No updates within 24hrs of next play day.</p>
        </div>
    </div>

    <iframe id="forecast_embed" type="text/html" frameborder="0" height="245" src="http://forecast.io/embed/#lat=35.795925&lon=-79.228608&name=Chapel Ridge&color=#6BB9F0&font=Open+Sans"> </iframe>

</div>  <!--End container div-->
</body>
</html>

以上是用户提交日期的网页。

if (($today=="Fri") && ($hd_flag=="yes"))
{       
    //Friday after the cron run
    echo "<div id=\"checkboxes\">
                <label class=\"tag\"><input type=\"checkbox\" name=\"MON_PRI\" value=\"YES\" class=\"regular-checkbox\"/>MON_PRI</label> 
                <label class=\"tag\"><input type=\"checkbox\" name=\"MON_ALT\" value=\"YES\" class=\"regular-checkbox\"/>MON_ALT</label> 
                <label class=\"tag\"><input type=\"checkbox\" name=\"WED\" value=\"YES\" class=\"regular-checkbox\" />WED</label> 
                <label class=\"tag\"><input type=\"checkbox\" name=\"FRI\" value=\"YES\" class=\"regular-checkbox\" />FRI</label>
            </div>";
}
elseif ($today=="Sat")
{
    echo "<div id=\"checkboxes\">
                <label class=\"tag\"><input type=\"checkbox\" name=\"MON_PRI\" value=\"YES\" class=\"regular-checkbox\"/>MON_PRI</label>

            </div>";
}
elseif (($today=="Mon") || ($today=="Sun")) 
{
    echo "<div id=\"checkboxes\">

            </div>";
} 

if(isset($_POST['playdaz'])) 
{
    $LastName=$_SESSION['LAST_NAME'];   

    $monpri = (isset($_POST['MON_PRI'])) ? "YES" :"NO";
    $monalt = (isset($_POST['MON_ALT'])) ? "YES" :"NO";
    $wed = (isset($_POST['WED'])) ? "YES" :"NO";
    $fri = (isset($_POST['FRI'])) ? "YES" :"NO";

    //Cannot select 2 courses on the same day
    if (($monpri =="NO") || ($monalt=="NO"))
    {       
        $LastName=$_SESSION['LAST_NAME'];       

        if (($today=="Fri") && ($hd_flag=="yes"))
        {   
            //Friday after the cron runs
            $query = "UPDATE players SET MON_PRI='$monpri',MON_ALT='$monalt',WED='$wed',FRI='$fri' WHERE LAST_NAME='$LastName'";
            mysqli_query($connection, $query);
        }
        elseif ($today=="Sat")
        {
            $query = "UPDATE players SET MON_PRI='$monpri',MON_ALT='$monalt',WED='$wed',FRI='$fri' WHERE LAST_NAME='$LastName'";
            mysqli_query($connection, $query);
        }
        elseif (($today=="Mon")||($today=="Sun"))
        {
            $query = "UPDATE players SET WED='$wed',FRI='$fri' WHERE LAST_NAME='$LastName'";
            mysqli_query($connection, $query);
        }
        elseif (($today=="Tue")||($today=="Wed"))
        {
            $query = "UPDATE players SET FRI='$fri' WHERE LAST_NAME='$LastName'";
            mysqli_query($connection, $query);
        }
    }
}

上面是更新数据库的函数的一部分

有关如何制作的任何帮助，以便在用户点击按钮后表更新以提供已做出更改的反馈？

干杯！

很容易做到。

您可以使用标题刷新功能，它将为您修复重定向属性。在使用它时，必须考虑两个基本的事情;它被正确放置在页面中并且正确的参数被传递到它中，其中包括我们应该在最终刷新到新位置之前等待多长时间。

将标题刷新放在PHP提交代码中符合逻辑的位置下方，或者更好地在PHP代码中输出任何内容之前。它必须放在任何<html>和<!doctype>标记之前。

对于你自己的情况，尝试这样的事情，

   if (($monpri =="NO") || ($monalt=="NO"))
   {       
       $LastName=$_SESSION['LAST_NAME'];       

       if (($today=="Fri") && ($hd_flag=="yes"))
    {   
        //Friday after the cron runs
        $query = "UPDATE players SET MON_PRI='$monpri',MON_ALT='$monalt',WED='$wed',FRI='$fri' WHERE LAST_NAME='$LastName'";
        mysqli_query($connection, $query);
    }
    elseif ($today=="Sat")
    {
        $query = "UPDATE players SET MON_PRI='$monpri',MON_ALT='$monalt',WED='$wed',FRI='$fri' WHERE LAST_NAME='$LastName'";
        mysqli_query($connection, $query);
    }
    elseif (($today=="Mon")||($today=="Sun"))
    {
        $query = "UPDATE players SET WED='$wed',FRI='$fri' WHERE LAST_NAME='$LastName'";
        mysqli_query($connection, $query);
    }
    elseif (($today=="Tue")||($today=="Wed"))
    {
        $query = "UPDATE players SET FRI='$fri' WHERE LAST_NAME='$LastName'";
        mysqli_query($connection, $query);
    }
 header("refresh:3; url=mywebpage.php?action=something&monpri=$monpri");
}

如果您需要，请在那里使用刷新。

在此之后，您尝试检查条件是否在您的网页上设置了某些内容，如果已设置，则显示数据库已相应更新。这样做;

<?php
if(isset($_REQUEST['action']) && $_REQUEST['monpri']="NO") {echo "Database updated accordingly";}?>

需要在PHP发布更新页面后刷新/重定向页面
