推荐答案
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
