小编Swe*_*ong的帖子

我有一些HTML代码如下:

<input name="bid" type="radio" value="1" id="1234"/>
<input name="bid" type="radio" value="2" id="5678"/>
<input type="text" id="paymount" name="paymount" value=""/>

所需功能:

当radio=1被选中时,paymount字段值将显示为1234.当radio=2被选中时,paymount字段值将显示为5678.

我在Stack Overflow上发现了帖子,但其中很多都与隐藏文本字段有关.

我有一个2数据库.

1是game_jnship_user,2是game_jnship_equip和以下数据:

这是 game_jnship_user

+-----+-----------------+
| ID  | uid             |
+-----+-----------------+
| 1   | 50              |
+-----------------------+

这是 game_jnship_equip

+-----+------------+---------------+--------------+
| ID  | uid        | ebonus        | etype        |
+-----+------------+---------------+--------------+
| 1   | 50         | 100           | 1            |
| 2   | 50         | 10            | 1            |
| 3   | 50         | 120           | 2            |
+-------------------------------------------------+

我查询如下:

$_G['uid'] = '50';
$ushuxing = DB::query("SELECT sum(t2.ebonus) AS equipatk, sum(t3.ebonus) AS equipdef FROM ".DB::table('game_jnship_user')." t1 LEFT JOIN …

我有一个数组。之后print_r($arr)如下：

Array ( 
  [0] => Array ( 
      [groupid] => 5 
      [radminid] => 1 
      [type] => system 
      [system] => private 
  ) 
  [1] => Array ( 
      [groupid] => 10 
      [radminid] => 2 
      [type] => system 
      [system] => private 
  )
)

我想将数组更改key为groupid，类似$arr[$arr[groupid]]，我尝试了

foreach($array as $key => $value){
    $arr[$value] = $arr[$arr['groupid']];
}

如何使用$arr[groupid]as $arr键？以下是我需要的。

Array ( 
  [5] => Array ( 
      [groupid] => 5 
      [radminid] => 1 
      [type] => system 
      [system] => private 
  ) …
