答

您的代码正确，那边的更改很小

Your code is right, just little change over there

<TR>
  <TD><INPUT type="checkbox" name="chk"/></TD>
  <TD> 1 </TD>
  <TD> <INPUT type="text" name="<?php echo $i; ?>"/> </TD>
</TR>

替换为该代码

<TR>
  <TD><INPUT type="checkbox" name="chkbox[]"/></TD>
  <TD> 1 </TD>
  <TD> <INPUT type="text" name="txtbox[]"/> </TD>
</TR>

您的工作完成
