Question

我有一个HTML表单，其中包含许多复选框。当用户单击提交按钮时，将发布已检查的数组，并根据该结果运行查询。我有一个按钮，允许用户在将保存的结果插入另一个表时保存结果。但这意味着我需要再次发布表单结果，但它不允许我这样做。我该如何解决这个问题？

PHP代码

<?php

if (isset($_POST['submit']) && isset($_POST['sport'])) {
    $class = $_POST["sport"];
    foreach ($class As $key => $value) {
        $query = "SELECT *
FROM sport b
join sport a
on a.Tag = b.Name
where a.SportID<> b.SportID and a.Tag = '$value'";

        $result = mysqli_query($con, $query) or die("Invalid Query");

        while ($row = mysqli_fetch_assoc($result)) {

            echo "* $row[Name]\n";
        }
    }
} else if (isset($_POST['saved'])) {


    $arr_class = $_POST["sport"];


    foreach ($arr_class As $key => $newvalue) {

        $query2 = "INSERT INTO save (Username, Name)
    SELECT '$username', b.Name
    FROM sport b 
    JOIN sport a 
    on a.Tag = b.Name
    where a.SportID <> b.SportID 
    and a.Name = '$newvalue'";

        $result2 = mysqli_query($con, $query2) or die('Result could not be saved!');


    }
    echo 'Result saved!';
}

JS代码

    $(document).ready(function(){
        $('.submit-button').click(function (ev) {
            var $item = $(this);
            var formData  = $('form').serialize();
            $.ajax({
                data: formData+'&submit=submit',
                url:'test1.php',
                type: "POST",
                dataType: "html",
                success:function (data) {
                    console.log(data);
                    if(confirm('You want to save \n'+data+ ' as your sport')){
                        $.ajax({
                            data: formData+'&saved=saved',
                            url:'test1.php',
                            type: "POST",
                            dataType: "html",
                            success:function (data) {
                                console.log(data);
                            }
                        });
                    }
                }
            });
        });
    });
</script>
