Hello Jasper,
Does your means :
I need to rewite the source / result page as the following ?
Result page:
<?
for($i=0;$i<4;$i++)
{
$f.$i=$_GET['$f.$i'];
}
?>
<table>
<tr>
<td><? echo $f0[0];?></td>
<td><? echo $f1[0];?></td>
<td><? echo $f2[0];?></td>
<td><? echo $f3[0];?></td>
</tr>
<tr>
<td><? echo $f0[1];?></td>
<td><? echo $f1[1];?></td>
<td><? echo $f2[1];?></td>
<td><? echo $f3[1];?></td>
</tr>
<tr>
<td><? echo $f0[2];?></td>
<td><? echo $f1[2];?></td>
<td><? echo $f2[2];?></td>
<td><? echo $f3[2];?></td>
</tr>
</table>
Source page:
<table>
<tr>
for($i=0;$i<4;$i++)
{
<td><input type=checkbox name='f<? echo $i;?>[]' value='1'></td>
}
</tr>
</table>
Thank for your help !
Edward.
