PHP数组复制条目，不记录数据值
我想知道是否有人有时间看一下我的代码并帮我一把。基本上，我下载了一个表单，它允许我点击AddRow，并根据需要添加任意多的输入框，效果很好 问题是，当我将它们添加到数据库中时，它会复制条目，此外，我不会获取数组值，只获取单个值 例如：如果我添加2个条目，我在数据库中得到4个条目，它们都如下所示： 客户ID |项目日期|项目代码|项目名称|数量|成本|添加用户 5 | 2020-07-06 |数组|数组|数组|数组| Me PHP代码PHP数组复制条目，不记录数据值,php,arrays,Php,Arrays,我想知道是否有人有时间看一下我的代码并帮我一把。基本上，我下载了一个表单，它允许我点击AddRow，并根据需要添加任意多的输入框，效果很好 问题是，当我将它们添加到数据库中时，它会复制条目，此外，我不会获取数组值，只获取单个值 例如：如果我添加2个条目，我在数据库中得到4个条目，它们都如下所示： 客户ID |项目日期|项目代码|项目名称|数量|成本|添加用户 5 | 2020-07-06 |数组|数组|数组|数组| Me PHP代码 function escape($html) { re

我需要在html方面看到更多的代码，但我的第一个想法是，每个条目的名称都是重复的，没有任何错误。例如如果它添加了一个name=name的新标记，并且您添加的下一个标记也会在应该添加类似name=name1的迭代的位置提供name=name。之后，post页面需要能够获取所有具有未知数量变量名的post数据。我很幸运地使用了whileiset$\u POST和for循环来迭代name变量。但我需要看到一个更完整的代码集循环遍历$entries=array$item\u code、$item\u name、$qty、$cost；这是不对的。您必须循环查看发票中每个项目的post数据数组
$query = "INSERT INTO `invoiceitems` (`client_id`, `item_date`, `item_code`, `item_name`, `qty`, `cost`, `added_user`) VALUES ";
$insert_rows = array();
//loop through item_code post data, inside this loop we will get other row data
foreach ($_POST['item_code'] as $k => $item_code_data) {
$insert_fields = array($client_id, $item_date, $item_code_data, $_POST['item_name'][$k], $_POST['qty'][$k], $_POST['cost'][$k], $added_user);
$insert_rows[] = implode("', '", $insert_fields);
}
if(count($insert_rows) > 0){
$insert_rows_data = " ('" . implode("'), ('", $insert_rows) . "') ";
mysqli_query($con, $query . $insert_rows_data);
}
var_dump$_POST；和var_dump$条目；因此，您可以了解数据的结构。此外，您根本没有在foreach循环中使用$row。要解决这个问题，1。了解你的数据，2。理解你的代码做什么，不要简单地模仿例子，3。把你的错误报告打开到最大限度，这样你就可以洞察到你的错误，这些错误很多，但你目前还没有看到。嗨，杰弗里。我在问题中公布了全部代码。感谢您感谢您解释这一点并提供有效的代码。虽然数据插入正确，但它只插入一行，而忽略所有其他行。有什么想法吗？循环是基于item_代码中的值工作的，所以如果它为空，整个过程将无法正常工作。我的假设是项目代码是强制性的。
