我有一个名为 logo_design_3.php 的 PHP 页面。我使用 Jquery 将变量“grand_total”发布到另一个名为 logo_design_3_sql.php 的页面。但不幸的是,有时我会在下一页上得到那个变量,有时没有。知道我在哪里做错了吗?

这是 logo_design_3.php 页面的片段:

<script type="text/javascript">
function load1() {
    document.getElementById('hide2').style.display = 'none';
    return false;
}

function toggle() {
    document.getElementById('hide1').style.display = 'none';
    document.getElementById('hide2').style.display = '';
    document.getElementById('hidrad').checked = 'true';
    document.getElementById('silver').checked = false;
    document.getElementById('bronze').checked = false;
    document.getElementById('gold').checked = false;
}

function load2() {
    document.getElementById('hide1').style.display = '';
    document.getElementById('hide2').style.display = 'none';
}
</script>
<script type="text/javascript">
$(document).ready(function() {

    var grand_total = 0;

    $("input").live("change keyup", function() {

        $("#Totalcost").val(function() {

            var total = 0;
            $("input:checked").each(function() {

                total += parseInt($(this).val(), 10);
            });
               var textVal = parseInt($("#min").val(), 10) || 0;

               grand_total = total + textVal;

               return grand_total;
        });

     });
         $("#next").live('click', function() {

        $.ajax({
            url: 'logo_design_3_sql.php',
            type: 'POST',
            data: {
                grand_total: grand_total
            },
            success: function(data) {
                // do something;

            }
        });

    });

});
 </script>
 <script type="text/javascript">
function validate() {
    var num = document.getElementById("min").value;
    var num = parseInt(num, 10);

    if (num < 299) {
        document.getElementById("min").value = "299";
        alert("Minimum Amount Should be 299");
    }
}

这是来自 logo_design_3_sql.php 页面:

<?php include ( "config.php"); 
$total=$_POST[ 'grand_total'];
 $sql="INSERT INTO form2 (total)VALUES('$total')" ; 
if($total>0)
{ $res = mysql_query($sql); } 
if($res) 
{ echo "<script> window.location.replace('logo_design_4.php')</script>"; }
 else { echo "<script> window.location.replace('logo_design_3.php')</script>"; }
 ?>

我也有关于 -> window.location.replace('logo_design_4.php') 的问题。即使 $total 已正确插入表中,插入后导航的页面也是“logo_design_3.php”。为什么这样?

请尝试如下直播功能

$("#next").live('click',function () {
    $.ajax({
            url: 'logo_design_3_sql.php',
            type: 'POST',
            data: {grand_total: grand_total},
            success: function(data) {}
        });
    });
});

您必须在全局范围内声明 grand_total 变量。

var grand_total = 0;
$(document).ready(function () {



$("input").live("change keyup", function () {

    $("#Totalcost").val(function () {

        var total = 0;
        $("input:checked").each(function () {

            total += parseInt($(this).val(), 10);
        });
        var textVal = parseInt($("#min").val(), 10) || 0;

        grand_total = total + textVal;

        return grand_total;
    });

});
$("#next").click(function () {

    $.ajax({
                url: 'logo_design_3_sql.php',
                type: 'POST',
                data: {grand_total: grand_total},
                success: function(data) {}
            });
        });
    });

请不要在生产系统上使用您的 PHP 代码。您必须检查您的 POST 变量(http://www.php.net/manual/en/security.database.sql-injection.php
