使用动态生成的字段（列表）从HTML表单收集数据

Question

I have a form where I generate a field on button click (fields are identical).

Until now I tried just using unique names for each field but then I can't loop through them because I don't know how many fields I have!

Can I use:

<ul>
   <li>
      <select name="personid">
         <options>...</options>
      </select>
      <select name="personid">
         <options>...</options>
      </select>
   </li> 
   <li>
      <select name="personid">
         <options>...</options>
      </select>
      <select name="personid">
         <options>...</options>
      </select>
   </li>
   ... 
</ul>

And then after I post the form loop through the list somehow and access all fields?

Any ideas on how to access the data after I post?

On your action page, all of the values for the same field name will be separated by commas. You can loop through them as a simple list. Just make sure your values don't contain commas!
