Question

我具有用于图像库的此表单数据，并使用jquery为每个新图像添加动态输入（添加删除输入字段）：

<div class="row-1">
   <input type="hidden" name="list_item_image_large[]" value="">
   <div class="form-group col-md-12">
      <input type="text" class="form-control name="list_item_title[]" value="">
   </div>
   <div class="form-group col-md-12">
      <input type="text" class="form-control name="list_item_image_description[]" value="">
   </div>
   <div class="form-group col-md-12">
      <input type="text" class="form-control name="list_item_image_photographer[]" value="">
   </div>
   <div class="form-group col-md-12">
      <input type="text" class="form-control name="list_item_image_copyright[]" value="">
   </div>
</div>
<div class="row-2">
   <input type="hidden" name="list_item_image_large[]" value="">
   <div class="form-group col-md-12">
      <input type="text" class="form-control name="list_item_title[]" value="">
   </div>
   <div class="form-group col-md-12">
      <input type="text" class="form-control name="list_item_image_description[]" value="">
   </div>
   <div class="form-group col-md-12">
      <input type="text" class="form-control name="list_item_image_photographer[]" value="">
   </div>
   <div class="form-group col-md-12">
      <input type="text" class="form-control name="list_item_image_copyright[]" value="">
   </div>
</div>

现在提交后，我有以下数据：

Array
(
    [list_item_image_large] => Array
        (
            [0] => uploads/images/posts/1586075502_3460aaee4378986bf677.jpg
            [1] => uploads/images/2020/04/1585774613_c2f7ed8d8b0458271371.png
        )

    [list_item_title] => Array
        (
            [0] => 
            [1] => 
        )

    [list_item_image_description] => Array
        (
            [0] => 
            [1] => 
        )

    [list_item_image_photographer] => Array
        (
            [0] => 
            [1] => 
        )

    [list_item_image_copyright] => Array
        (
            [0] => 
            [1] => 
        )
)

现在，我需要为mysql数据库中的每个图像插入图像数据（标题，描述，摄影师，版权）。怎么插入？！

Answer 1

执行此操作的最佳方法是使用不同的结构。

Array
(
    [0] => Array
        (
            [list_item_title] => value
            [list_item_image_description] => value
            [list_item_image_photographer] => value
            [list_item_image_copyright] => value
        )

    [1] => Array
        (
            [list_item_title] => value
            [list_item_image_description] => value
            [list_item_image_photographer] => value
            [list_item_image_copyright] => value
        )
)

使用这种结构，您可以简单地使用for（each）循环

for($i=0; $i<count($array); $i++) {
  // mysql_stuff, can access field values like this: $array[$i]['list_item_title']
}

但这需要在html输入字段上使用不同的命名。

<input type="text" class="form-control name="image[0][list_item_title]" value="">
...
<input type="text" class="form-control name="image[1][list_item_title]" value="">
...

重复字段的逻辑含义会有所不同，但是提交后处理数据将变得更加容易。

首先将数据汇总到各个项目中。这样的事情（存在更奇特的方式）：

$items = [];

foreach($data['list_item_image_large'] as $num => $val) {
    $item[$num] = [
        'list_item_image_large' => $val,
        'list_item_title' => $data['list_item_title'][$num],
        'list_item_image_description' => $data['list_item_image_description'][$num],
        'list_item_image_photographer' => $data['list_item_image_photographer'][$num],
        'list_item_image_copyright' => $data['list_item_image_copyright'][$num]
    ];
}

var_dump($items); // See what you got there

您遵循上面的代码的工作原理，对吗？之后，使用与MySQL交互的首选方法将数据插入数据库应该足够容易。我认为您通常知道如何插入数据，并且您只是在努力处理数据的结构。

PHP将多个动态输入数据插入数据库
