POST an array from an HTML form without javascript
提问by styfle
I have a form that is a little complex and I am hoping to simplify the server-side (PHP) processing by natively POSTing an array of tuples.
我有一个有点复杂的表单,我希望通过本地 POST 元组数组来简化服务器端 (PHP) 处理。
The first part of the form represents a User:
表单的第一部分代表一个User:
- First Name
- Last Name
- Address
- etc
- 名
- 姓
- 电子邮件
- 地址
- 等等
The second part of the form represents a Tree:
表单的第二部分代表一棵树:
- Fruit
- Height
- etc
- 水果
- 高度
- 等等
The problem is that I need to be able to POST multiple Treesfor a single Userin the same form. I would like to send the information as a single Userwith an array of Treesbut this might be too complex to do with a form. The only thing that comes to mind is using javascript to create some JSON message with a User object and an array of Tree objects. But it would be nice to avoid javascript to support more users (some people have scripts turned off).
问题是我需要能够以相同的形式为单个用户发布多个树。我想将信息作为具有树数组的单个用户发送,但这可能太复杂而无法使用表单。唯一想到的是使用 javascript 创建一些带有 User 对象和 Tree 对象数组的 JSON 消息。但是最好避免使用 javascript 来支持更多用户(有些人关闭了脚本)。

<input type="text" name="firstname">
<input type="text" name="lastname">
<input type="text" name="email">
<input type="text" name="address">
<input type="text" name="tree[tree1][fruit]">
<input type="text" name="tree[tree1][height]">
<input type="text" name="tree[tree2][fruit]">
<input type="text" name="tree[tree2][height]">
<input type="text" name="tree[tree3][fruit]">
<input type="text" name="tree[tree3][height]">
it should end up like this in the $_POST[] array (PHP format for easy visualization)
它应该在 $_POST[] 数组中像这样结束(PHP 格式,便于可视化)
$_POST[] = array(
'firstname'=>'value',
'lastname'=>'value',
'email'=>'value',
'address'=>'value',
'tree' => array(
'tree1'=>array(
'fruit'=>'value',
'height'=>'value'
),
'tree2'=>array(
'fruit'=>'value',
'height'=>'value'
),
'tree3'=>array(
'fruit'=>'value',
'height'=>'value'
)
)
)

You can also post multiple inputs with the same name and have them save into an array by adding empty square brackets to the input name like this:
您还可以发布具有相同名称的多个输入,并通过在输入名称中添加空方括号将它们保存到数组中,如下所示:
<input type="text" name="comment[]" value="comment1"/>
<input type="text" name="comment[]" value="comment2"/>
<input type="text" name="comment[]" value="comment3"/>
<input type="text" name="comment[]" value="comment4"/>
If you use php:
如果您使用 php:
print_r($_POST['comment'])
you will get this:
你会得到这个:
Array ( [0] => 'comment1' [1] => 'comment2' [2] => 'comment3' [3] => 'comment4' )
