数组索引数组 php 上的 Foreach 循环

Question

On the first page there is a form with a jquery script to add days.在第一页有一个带有 jquery 脚本的表单来添加天数。 If I just use one day I cant get all the info I need.如果我只使用一天，我将无法获得所需的所有信息。 But when I add multiple days I just get the last entry.但是当我添加多天时，我只会得到最后一个条目。

I am trying to see every day of the event I book in the table on the next page book_gear.php.我试图查看我在下一页 book_gear.php 的表格中预订的活动的每一天。 But so far I am only see one day of the event.但到目前为止，我只看到了这一事件的一天。

I think it is because my foreach loop is going thought the array indexs rather than each event in the array.我认为这是因为我的 foreach 循环将考虑数组索引而不是数组中的每个事件。

EDIT编辑

After suggested in the comments ran在评论中建议运行后

echo '<pre>'; var_dump($events);echo '</pre>';die(); before the foreach loop

Result结果

array(1) {
  [1]=>
  array(5) {
    ["eventNameInitialQuery"]=>
    string(4) "Day2"
    ["dateFromIntialQuery"]=>
    string(10) "2020-07-23"
    ["timeFromIntialQuery"]=>
    string(5) "18:57"
    ["dateToIntialQuery"]=>
    string(10) "2020-07-11"
    ["timeToIntialQuery"]=>
    string(5) "19:54"
  }
}

Answer 1

I've done a quick test and the problem is with disabling the earlier inputs when adding a new event row.我做了一个快速测试，问题是在添加新事件行时禁用早期的输入。 What you could do is copy the values of your inputs to hidden inputs before you disable them.您可以做的是在禁用它们之前将输入的值复制到隐藏输入。
