php批量修改问题
表 user 
user_id  money
 1        1000
 2        1500
 3        1200
 4        1300

如何批量修改money字段?
前端代码:
 
 
 

问:如何处理$_POST['user']和$_POST['jf']两个数组,并保证两个值是一一对应的?
具体的代码如何写?先谢谢大家!
------解决方案--------------------
没有被选中的 checkbox 不会被提交
checkbox 提交的是值(数组)

按你的设计
$_POST['jf'][$_POST['user'][i]-1] 就是 user 对应的 jf
i 为传入的 $_POST['user'] 数组的下标

通常宜这样做
 
 
使得一开始就一一对应
------解决方案--------------------

 
 


<br />$jf 	= $_POST['jf'];<br />$user 	= $_POST['user'];<br />foreach($user as $v){<br />	echo $jf[$v];<br />}<br />

------解决方案--------------------
 
 
foreach($_POST['user'] as $k) {<br />  printf('%s %s', $k, $_POST['jf'][$k-1]);<br />}

 
 
foreach($_POST['user'] as $k) {<br />  printf('%s %s', $k, $_POST['jf'][$k]);<br />}
