Help with a while please..

Hey guys, I'm stuck solid on something at the mo, I understand in theory how it should work, but just can't figure it out. I have these two bits of code:

PHP Code:

session_start();
if (!isset($_SESSION['secure'])) {
    if (!$_GET['clicked']) {
        $numimgs = $vbulletin->options['eic_numimgs'];
        $answer_position = rand(1,$numimgs);
        $d = dir($vbulletin->options['eic_imgpath']);
        while (false !== ($entry = $d->read())) 
            if ($entry != '.' && $entry != '..' && $entry != 'show.php' && $entry != '.htaccess' && $entry != 'Thumbs.db')
                $answers[] .= $entry; 
        $amount = count($answers);
        $the_answer = rand(1,$amount);
        for($i=1;$i<$numimgs;$i++) {
            if ($answer_position == $i) $show_image[] = $the_answer;
            $tmp = rand(1,$amount);
            while ($tmp == $the_answer || (is_array($show_image) && in_array($tmp,$show_image))) $tmp = rand(1,$amount);
       $show_image[] = $tmp;
        }  
        if ($answer_position == $i) $show_image[] = $the_answer;
        $d->close();

        $_SESSION['answer_position'] = $answer_position;
        $_SESSION['show_images'] = $show_image;
        $question = substr($answers[$the_answer-1],0,-4);
    } 
    else {
        if ($_GET['clicked'] == $_SESSION['answer_position']) $_SESSION['secure'] = 1;
        else $badchoice = 1;
    }
    if (!isset($_SESSION['secure'])) {
        eval('$navbar = "' . fetch_template('navbar') . '";');
        eval('print_output("' . fetch_template('image_verification') . '");');
    }
} 


That's the main chunk of code, I also have this:

PHP Code:

$t = 1;
while($t <= $vbulletin->options['eic_numimgs'])
   {
   $numings = $t;  
   eval('$imagebits = "' . fetch_template('imagebits') . '";');
   $t = $t+1;
   } 


Now, I'm not too sure the code above is correct but basically, what I need to happen is for the imagetbits template to be called as many times as dictated in $vbulletin->options['eic_numimgs'] (say 5 for example).

The main chunk of code also counts the same amount of times (5), but I can't combine both and make it work ... it only ever appears once! What do I need to do to get this working?

Cheers!

Try:

PHP Code:

eval('$imagebits .= "' . fetch_template('imagebits') . '";'); 


(.= not just =)

What Lynne is saying, by the way, is remember to concatenate.

Yeah, exactly.

(Sorry, I have no formal programming background and don't always know the terminology.)

Thanks ... I see that error now, but I'm having major issues trying to include that in the while .... so it loops the template as many times as set in $eic_numimgs -- it won't show - at all.

Any advice?

Cheers
