anchor question

[eluser]dimaomni[/eluser]
hello guys!
when I just output $marks all has been outputed good.

about output - it is table where is cells with marks and empty cells

when I've started used anchor function in empty cells has outputed links.

So how to avoid this situation ?
There is some piece of code:

Code:

foreach ($output_array as $key=>$marks)
          { ?>
            <td>&lt;?=anchor('index.php/adminka/'.$marks, $marks)?&gt;
              &lt;?=(!$marks) ? "&nbsp;":NULL // however if $marks = 0, it output &npsp;?&gt;
            </td>

Thanks!

I believe it is still outputted because it exists. You have not used any typecasting, so 0 exists. You may want to try

Code:

<?=($marks != '0') " " : '';?>

foreach ($output_array as $key=>$marks)
{ ?>
<td>&lt;?=anchor('index.php/adminka/'.$marks, $marks)?&gt;
&lt;?=($marks === FALSE) ? "&nbsp;":NULL // however if $marks = 0, it output &npsp;?&gt;
</td>
