无法使用 Javascript Link 提交我的表单

Question

我尝试提交我的表单，该表单有两个不同的链接，指向删除和编辑 php 文件，但我注意到这些链接没有将单选按钮的值提交给 php 文件尤其是删除 php 文件。但是当我更改按钮的链接时，该值已提交。请问我不想使用按钮标签，我怎样才能使值通过我的链接传递到 php 文件？

表格如下：

<form action="del_cn_rec.php" method="POST" id="consignments" >
              <table id="example1" class="table table-hover table-bordered table-striped">
                <thead>
                <tr>
                  <th>ID</th>
                  <th>Consignment No</th>
                  <th>Sender</th>
                  <th>Reciever</th>
                  <th>Pickup Date/Time</th>
                  <th>Msg_Status</th>
                  <th>Status</th>
                  <th>Action</th>
                  <th>Action</th>
                </tr>

这里是删除 php 文件：del_cn_rec.php

<?php 
session_start();
include '_inc/dbconn.php'; 
$sql="SELECT * FROM admin WHERE id='1'";
$result= mysql_query($sql);
$rws= mysql_fetch_array($result);
$email_1= $rws[3];
$email_2= $rws[4];
$phone= $rws[5];
$address= $rws[6];
$url= $rws[7];
if(!isset($_SESSION['admin_login']))
header("location:$url/server-side");  
?>
<?php 
            $id=  mysql_real_escape_string($_REQUEST['cn_id']);
            $sql1="SELECT * FROM consignments WHERE id='$id'";
            $result1= mysql_query($sql1);
            $rwsn= mysql_fetch_array($result1);
            $cn= $rwsn[1];

            $sql2="DROP TABLE IF EXISTS ".$cn."status ";
            mysql_query($sql2) or die(mysql_error());

            $sql3="DROP TABLE IF EXISTS ".$cn."msg ";
            mysql_query($sql3) or die(mysql_error());

            $sql6 = mysql_query("SELECT * FROM admin_inbox WHERE cn='$cn'");
            if (mysql_fetch_row($sql6)){
            $sql4="DELETE FROM admin_inbox WHERE cn='$cn'";
            mysql_query($sql4) or die(mysql_error());
            }

            $sql5="DELETE FROM consignments WHERE id='$id' AND cn='$cn'";
            mysql_query($sql5) or die(mysql_error());

            //Consignment Remove Success Msg
            $msg = "<i class=\"fa fa-check\"></i> Consignment: $cn Has Been Successfully Deleted!";
            header("Location:$url/server-side/consignments?msg=$msg");

?>

Answer 1

这通常应该有效，只需确保您的 php 日志或生成的 html 中没有任何错误或通知，或者浏览器控制台。确保单选按钮的值填写在 html 中（也许您从 sql 得到错误的结果）。

此外，我希望您知道必须先 select 单选按钮，然后才单击 "Delete" 或 "Edit" link - 这有点令人困惑在这里，因为你把 link 放在每一行。单选按钮仅在 selected 时才发送值，否则它们甚至不会出现在 POST 数据中。

如果你想在每一行使用 link 而不先 select 单选按钮，你必须将 cn_id 作为参数传递给 askForDelete_Rec() 函数然后在那里使用它。输入类型="hidden" 可能对此有用，或者只是将其作为 GET 参数附加到操作中。
