PHP - 复选框组 [英] PHP - Checkbox group

问题描述

 < input type =复选框我的复选框组以一种形式发布， value =truechecked name =chk0 []> 
< input type =checkboxvalue =falsename =chk0 []> 
< input type =checkboxvalue =falsename =chk0 []> 
< input type =checkboxvalue =truechecked name =chk0 []> 
 
< input type =checkboxvalue =truechecked name =chk1 []> 
< input type =checkboxvalue =falsename =chk1 []> 
< input type =checkboxvalue =truechecked name =chk1 []> 
< input type =checkboxvalue =falsename =chk1 []> 
  

请注意，在第一组中，检查1和4。在第二组中，检查1和3。
当我发布这篇文章时，我会依次获取选中复选框的发布值：

  [chk0] = >数组（
 [0] => true 
 [1] => true 
）
 [chk1] => Array（
 [0] => true 
 [1] => true 
）
  

我如何确保获得像这样的发布值：

  [chk0] => ; Array（
 [0] => true 
 [3] => true 
）
 [chk1] => Array（
 [0] => true 
 [2] => true 
）
  

我想知道选中复选框的键，而不是按顺序显示我。

谢谢

解决方案

 < input type =checkboxvalue =truechecked name =chk0 [0]> 
< input type =checkboxvalue =falsename =chk0 [1]> 
< input type =checkboxvalue =falsename =chk0 [2]> 
< input type =checkboxvalue =truechecked name =chk0 [3]> 
 
< input type =checkboxvalue =truechecked name =chk1 [0]> 
< input type =checkboxvalue =falsename =chk1 [1]> 
< input type =checkboxvalue =truechecked name =chk1 [2]> 
< input type =checkboxvalue =falsename =chk1 [3]> 
  

查看我的意思？

<输入名称=chk0 [1]...> 框与PHP中的数组元素一样工作。您可以指定将它们原样传输到PHP中的索引，如 $ _ POST ['chk0'] [1] 元素。

I have a checkbox group in one form that I need to be posted.

<input type="checkbox" value="true" checked name="chk0[]">
<input type="checkbox" value="false" name="chk0[]">
<input type="checkbox" value="false" name="chk0[]">
<input type="checkbox" value="true" checked name="chk0[]">

<input type="checkbox" value="true" checked name="chk1[]">
<input type="checkbox" value="false" name="chk1[]">
<input type="checkbox" value="true" checked name="chk1[]">
<input type="checkbox" value="false" name="chk1[]">

Note that in the first group, 1 and 4 are checked. In the second group, 1 and 3 are checked. When I post this, I get the posted values for the checked checkboxes sequentially as under:

[chk0] => Array ( 
          [0] => true 
          [1] => true 
        ) 
[chk1] => Array ( 
          [0] => true 
          [1] => true 
        ) 

How can I make sure I get the posted values like this:

[chk0] => Array ( 
          [0] => true 
          [3] => true 
        ) 
[chk1] => Array ( 
          [0] => true 
          [2] => true 
        ) 

I wanted to know the keys of the checked checkboxes instead of showing me sequentially.

Thanks

解决方案

<input type="checkbox" value="true" checked name="chk0[0]">
<input type="checkbox" value="false" name="chk0[1]">
<input type="checkbox" value="false" name="chk0[2]">
<input type="checkbox" value="true" checked name="chk0[3]">

<input type="checkbox" value="true" checked name="chk1[0]">
<input type="checkbox" value="false" name="chk1[1]">
<input type="checkbox" value="true" checked name="chk1[2]">
<input type="checkbox" value="false" name="chk1[3]">

See what I mean?
The <input name="chk0[1]" ...> boxes work just like array elements inside PHP. You can specify the indexes an they will be transfered as-is into PHP as $_POST['chk0'][1] elements.
