Question

I have some code like this.

$counter = 1;
$content = "";
foreach($images as $image) {
    $content .= "<li><img src='".$image['images_image'][1]['thumb']."'></li>";
    $counter++;
}
echo apply_filters('images_filter', $content);

The above code hides the whole content by using WordPress filters. But I would like to hide only the last 50% of images.

Let’s say I have 15 images.

$hide = floor( $counter / 2 ); //value will be 7

So I would like to hide only images from 8 to 15.

I’ve tried like this. But it’s not working.

if ($counter >= $hide) {
    echo apply_filters('images_filter', $content);
}

Can someone tell me the correct syntax?

I don’t know the image filter, but this should work:

  $show = ceil( count($images) / 2 );      
  $counter = 1;
  $content = "";
  foreach($images as $image){
        if($counter<=$show){
            $content .= "<li><img src='".$image['images_image'][1]['thumb']."'></li>";
        }else{
            break;
        }
        ++$counter;
     }
    echo apply_filters('images_filter',$content);
