Question

我运行了一个数组循环，如果数组的数据大于1则会抛出错误，否则它会正常工作。你能指出错误吗？

这是第一圈

此循环将数据存储到数组$resultArr

中

$resultArr = array();
    $i = 0;

foreach($_POST['item_cid'] as $key => $value) {
//Data for Orders Table
    $cid = intval(mysqli_real_escape_string($connection,$value));
    $pcode = mysqli_real_escape_string($connection,$_POST['item_code'][$key]);
    $pname = mysqli_real_escape_string($connection,$_POST['item_name'][$key]);
    $pprice = mysqli_real_escape_string($connection,$_POST['item_price'][$key]);
    $pqty = mysqli_real_escape_string($connection,$_POST['item_qty'][$key]);

    $resultArr[$i] = array('cid' => $cid, 'pcode' => $pcode, 'pname' => $pname, 'pprice' => $pprice, 'pqty' => $pqty);
    $i++;

//Data for Customers Table
    $cname = mysqli_real_escape_string($connection,$_POST['item_cname'][$key]);
    $cemail = mysqli_real_escape_string($connection,$_POST['item_cemail'][$key]);
    $cphone = mysqli_real_escape_string($connection,$_POST['item_cphone'][$key]);
    $caddress = mysqli_real_escape_string($connection,$_POST['item_caddress'][$key]);
    $ctotal = mysqli_real_escape_string($connection,$_POST['item_ctotal'][$key]);

}

这是第二圈

此循环打印来自$resultArr

的数组数据

for ($i=0; $i < ((isset($resultArr[$i]['cid']))); $i++) {
        $message .= '<tr>
         <td>' . $resultArr[$i]['pcode'] . '</td>
         <td>' . $resultArr[$i]['pname'] . '</td>
         <td>' . $resultArr[$i]['pprice'] . '</td>
         <td>' . $resultArr[$i]['pqty'] . '</td>
         </tr>';
 }

请注意：

这样可以正常工作，直到$resultArr只有1条记录，否则会收到错误/通知。

注意：未定义的偏移量：第26行的C：\ wamp \ www \ abc \ process.php中的1

注意：未定义的偏移量：第27行的C：\ wamp \ www \ abc \ process.php中的1

注意：未定义的偏移量：第28行的C：\ wamp \ www \ abc \ process.php中的1

注意：未定义的偏移量：第29行的C：\ wamp \ www \ abc \ process.php中的1

注意：未定义的偏移量：第30行的C：\ wamp \ www \ abc \ process.php中的1

所有这些行都指向$resultArr

之后定义的变量

更新

添加了HTML表单

//hidden inputs holds the data from DB (they're never empty)
<input type="hidden" name="item_cid[]" value="78286" />

Answer 1

您不应该使用数组表示法来处理送货详情，因为整个订单只有一个送货地址。所以将表单更改为：

    echo '<p>Please provide your billing/shipping details to proceed.</p>'."\xA";

    echo '<p class="form-row">
    <label class="" for="item_cname">Your Name <span class="required">*</span></lable>
    <input class="input-text" type="text" name="item_cname" placeholder="Your Name" />
    </p>'."\xA";

    echo '<p class="form-row">
    <label class="" for="item_cemail">Email Address <span class="required">*</span></lable>
    <input type="text" name="item_cemail"  placeholder="Your Email Address"/>
    </p>'."\xA";

    echo '<p class="form-row">
    <label class="" for="item_cphone">Phone Number <span class="required">*</span></lable>
    <input type="text" name="item_cphone"  placeholder="Your Phone Number"/>
    </p>'."\xA";

    echo '<p class="form-row">
    <label class="" for="item_caddress">Address <span class="required">*</span></lable>
    <textarea name="item_caddress"  placeholder="Your Address" class="input-text" rows="2" cols="2" maxlength="140"></textarea>
    </p>'."\xA";

    echo '<input type="hidden" name="item_ctotal"  value="'.$total.'"/>'."\xA";

并更改处理代码以仅插入一次客户信息，而不是循环。

foreach($_POST['item_cid'] as $key => $value) {
    //Data for Orders Table
    $cid = intval(mysqli_real_escape_string($connection,$value));
    $pcode = mysqli_real_escape_string($connection,$_POST['item_code'][$key]);
    $pname = mysqli_real_escape_string($connection,$_POST['item_name'][$key]);
    $pprice = mysqli_real_escape_string($connection,$_POST['item_price'][$key]);
    $pqty = mysqli_real_escape_string($connection,$_POST['item_qty'][$key]);

    $resultArr[$i] = array('cid' => $cid, 'pcode' => $pcode, 'pname' => $pname, 'pprice' => $pprice, 'pqty' => $pqty);
    $i++;

    $sql = "INSERT INTO orders (cid, ordprod_code, ordprod_name, ordprod_price, ordprod_qty) VALUES ('$value', '$pcode', '$pname', '$pprice', '$pqty')";

    mysqli_query($connection,$sql);

} // close the loop

//Data for Customers Table
$cname = mysqli_real_escape_string($connection,$_POST['item_cname']);
$cemail = mysqli_real_escape_string($connection,$_POST['item_cemail']);
$cphone = mysqli_real_escape_string($connection,$_POST['item_cphone']);
$caddress = mysqli_real_escape_string($connection,$_POST['item_caddress']);
$ctotal = mysqli_real_escape_string($connection,$_POST['item_ctotal']);

$sql2 = "INSERT INTO customers (cid, cname, cemail, cphone, caddress, ctotal) VALUES ('$value','$cname','$cemail','$cphone','$caddress','$ctotal')";
mysqli_query($connection,$sql2);

Answer 2

根据我的理解，如果我错了，请纠正我，你有一组重复的值，例如：item_code，item_name，item_price，{{1} }。所以你在第一个循环中循环了它们。但是像item_qty，item_cname，item_cemail，item_cphone，item_caddress这样的字段是否也像上面那样重复。如果不是，那就是你的问题。您试图在循环中获取item_ctotal的值，如item_cname。

如果这些值没有重复或只有一个值，那么我建议你改变你的代码

$_POST['item_cname'][$key]

如果大于1的数组值出错
