Php 在CodeIgniter中使用Ajax分配数据

这是购物车视图

        <div id="cart" >

            <div id="text">
                <?php  $cart_check = $this->cart->contents();

                    // If cart is empty, this will show below message.
                    if(empty($cart_check))
                    {
                        echo 'To add products to your shopping cart click on "Add to Cart" Button';
                    }  ?> </div>

            <table id="table" border="0" cellpadding="5px" cellspacing="1px" class="table table-hover" style="padding: 0px;margin: 0px;text-align: center">
                <?php
                    // All values of cart store in "$cart".
                    if ($cart = $this->cart->contents()): ?>
                        <tr id= "main_heading">
                            <td width="5%">Serial</td>
                            <td width="30%">Name</td>

                            <td width="25%">Amount</td>
                            <td width="10%">Cancel Product</td>
                        </tr>
                        <?php

                            //  Will produce the following output.
                            // <input type="hidden" name="cart[1][id]" value="1" />

                            ?>
                            <tr>
                            <td>
                                <?php echo $i++; ?>

                                <!-- "Place order button" on click send "billing" controller  -->
                                <!--                                    <input type="button" class ='fg-button teal' value="Place Order" onclick="window.location = 'index.php/cart/billing_view'">-->
                                <button id="placeorder" type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@mdo" style="margin-left: 5px">Place Order</button>
                            </td>

                        </tr>
                    <?php endif; ?>
            </table>
        </div>

所有这些都可以使用ajax

<script>
    $(function(){
        $( "#placeorder" ).click(function(event){
            event.preventDefault();
            var htmlString = $("#mail_table").html();
            $.ajax({
                type : 'post',
                url : '<?php echo base_url();?>index.php/cart/send_mail',
                data : $('#form').serialize() + "table" + htmlString
            });
        });  
    });
</script>

但我犯了个错误

遇到一个PHP错误

严重性：通知

消息：未定义索引：表

文件名：controllers/cart.php

行号：144

---

有什么想法吗？

问题在于您认为ajax中的这行代码。使用此代码

表

不发送参数。您的表单id也是

mailform

data : $('#form').serialize() + "table" + htmlString

是的

data : $('#mailform').serialize() + "&table=" + encodeURIComponent(htmlString)

---

查看购物车控制器的第144行。您尚未与我们共享它。

$message=$\u POST['table']//第144行

就是这样，PHP不同意您的意见，我无法理解@scrowler。你能帮我澄清一下吗？？？这个错误是不言自明的，关于堆栈溢出有成千上万的问题与之相关。您是否尝试搜索该错误消息？请检查此项。你错过了什么吗

alert（htmlString）

我想你是在用ajaxya发送整个表格的html。这就是我真正需要的，为什么你不为此创建一个单独的视图

     public function send_mail()
      {
        $name = $_POST['name'];
        $mail = $_POST['mail'];
        $mob = $_POST['mob'];
        $price = $_POST['price'];
        $msg = $_POST['msg'];

        //                $to =
        $to = 'mail@gmail.com';


        $to = 'my@gmail.com';
        $subject = 'Enquiry from ' .$name;
        $message = $_POST['table']; //Line 144
        $headers = "MIME-Version: 1.0\r\n";
        $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
        //                    $headers .= 'From: '.$_REQUEST['email'];
        if(mail($to, $subject, $message, $headers))
        {

        }

    }

data : $('#form').serialize() + "table" + htmlString

data : $('#mailform').serialize() + "&table=" + encodeURIComponent(htmlString)
