I want to display a default image when no image is uploaded in the CMS.

So far I got this code:

<li><img alt="" class="img-responsive" src="
                        <? if($artikel[0]['images'] == ''){ ?>
                                images/defaultimg.jpg
                        <? }else{ ?>
                        cms/images/<?

                                $plaatje = $artikel[0]['images'];
                                $plaatje = explode('\/', $plaatje);
                                $plaatje = $plaatje[1];
                                $plaatje = explode('"', $plaatje);
                                $plaatje = $plaatje[0];
                                echo $plaatje;

                        }
                        ?>"></li>

But this does not display the image. I know the image is there, so I think something is wrong with the outputted html code.

Anyone see it?

Thanks

Output code as requested:

<img alt="" class="img-responsive" src="
                                                                cms/images/">

I got the correct code:

                <?php
                  $image = "images/defaultimg.jpg";

                  $pl = $artikel[0]['images'];
                  $pl = explode('\/', $pl);
                  $pl = $pl[1];
                  $pl = explode('"', $pl);
                  $pl = $pl[0];
                  $pl = explode('.', $pl);
                  $pl = $pl[1];

                  echo $pl;

                  if($pl == 'jpg'){ //Check if string is empty
                      $plaatje = $artikel[0]['images'];
                      $plaatje = explode('\/', $plaatje);
                      $plaatje = $plaatje[1];
                      $plaatje = explode('"', $plaatje);
                      $plaatje = $plaatje[0];
                      // If the string supplied in the if condition isn't empty i assume that there's an image
                      // so i prepend the imagefolder as source
                      $image = 'cms/images/'.$plaatje;
                  }

                  $html = '<li><img alt="" class="img-responsive" src="'.$image.'"></li>';

                  echo $html

                ?>

Why not just separate the if else logic from your markup instead of cluttering it up on that source attribute. Example:

<?php

$image = '';
if($artikel[0]['images'] == '') {
    $image = 'images/defaultimg.jpg'; // wrap it with quotes
} else {
    $plaatje = $artikel[0]['images'];
    $plaatje = explode('\/', $plaatje);
    $plaatje = $plaatje[1];
    $plaatje = explode('"', $plaatje);
    $image = 'cms/images/' . $plaatje[0]; // append the filename with that particular path
}

?>

<li><img alt="" class="img-responsive" src="<?php echo $image; ?>"></li>
