在数据库中存储多维复选框 [英] Store Multidimensional checkbox in database

问题描述

我想将复选框存储在数据库中。但是该复选框比常规的有点复杂。
基本上这是我要实现的。

I want to store checkbox in database.. but the checkbox is a bit complex than regular. Basically this is what I want to implement.

我能够从输入中收集数据并将其存储在数组中，但是我无法按顺序显示它。

我给出的输入示例。

这就是我print_r（）时得到的结果数组：

I am able to collect data from input and store it in an array, but I am not able to display it in sequence.
Example of inputs that I give.
Then this is what I get when I print_r() the array:

Array ( [aadhar] => Array ( [original] => 1 ) [pan] => Array ( [original] => 1 ) [address] => Array ( [xerox] => 1 ) [lightbill] => Array ( [original] => 1 ) )

我的HTML代码。

 <table>
      <tr>
      <td>Aadhar</td>
      <td><input type="checkbox" name="document[aadhar][original]" value="1"/></td>
      <td><input type="checkbox" name="document[aadhar][xerox]" value="1"/></td>
      </tr>
      <tr>
      <td>Pan Card</td>
      <td><input type="checkbox" name="document[pan][original]" value="1"/></td>
      <td><input type="checkbox" name="document[pan][xerox]" value="1"/></td>
      </tr>
      <tr>
      <td>Address</td>
      <td><input type="checkbox" name="document[address][original]" value="1"/></td>
      <td><input type="checkbox" name="document[address][xerox]" value="1"/></td>
      </tr>
      <tr>
      <td>Light Bill</td>
      <td><input type="checkbox" name="document[lightbill][original]" value="1"/></td>
      <td><input type="checkbox" name="document[lightbill][xerox]" value="1"/></td>
      </tr>
      <tr>
      <tr>
      <td><input type="submit" value="Submit" /></td>
      </tr>
    </table>

问题：
用户单击提交后，我想向他显示他的选择， （如确认）。
示例：

PROBLEM: After the user click submit, I want to show him, his selection,(like a confirmation). Example:

Document Selected
----------------- 
Adhaar - Original 
Pan card - Original
Address - xerox 
Light bill - Original

我应该怎么做？我尝试了foreach（），但无法正常工作。
即使我尝试像 echo document [adhaar] [orginal]; 这样的简单显示，它仍然显示错误！

How should I do it? I tried foreach() but not working. Even when I try to simple display like echo document[adhaar][orginal]; still it shows error!

推荐答案

首先：您是说要使用单选按钮代替？如果此人只能每行选择原始或施乐，则可能需要单选按钮而不是复选框。

First: Do you mean to be using radio buttons instead? If the person should only be able to choose Original OR Xerox per row, you might want radio buttons instead of checkboxes.

也就是说，如果您希望复选框，则输出PHP类似于：

That said, if you do want checkboxes, the output PHP would be something like:

<?php

// loops through each "document" value in the POST
foreach($_POST['document'] as $key => $val) {
    echo $key; // print the key for each value in document (what you treat as a "row"
    foreach($val as $k => $v) {
       echo " - ".$k; // print EACH value within that key (what you thread as a "column"
    }
    echo "<br/>\n"; // after all columns per row are printed, print a line break
}

一些值得一读的东西：

1. 关联数组


2. foreach （尤其是使用 $ key => $ val 结构）


3. key 函数

1. associative arrays
2. foreach (especially using the $key => $val structure)
3. the key function
