skip image

[Marty Walker]

Hi everyone,

I've got a news section setup on a site in development. I want to pull the most recent three news items onto the home page. All good except for a small image issue. I have an image field in the news entry and below I'm calling the first one there for the thumbnail. What I'm stuck with is how to skip/ignore that instruction if there's no image. Most of the time there will be an image but I want to cover myself in case there's not.

Regards

Martin

<?php
$today = time();
$news = $pages->get("/news-and-events/")->find("limit=3, template=news-entry, sort=-publish_date, publish_date<$today");
foreach($news as $newsitem) {
$newsimage = $newsitem->images->first();
    if(!$newsimage) continue; // NOT SURE WHAT TO DO HERE
$newsthumb = $newsimage->size(80,80);
    if(!$newsthumb) continue; // NOT SURE WHAT TO DO HERE
echo "<dl class='clearfix'>
		<dt><a href='{$newsitem->url}'>{$newsitem->title}</a></dt>	
		<dd class='image'><img src='{$newsthumb->url}' alt='{$newsitem->title}' width='80' height='80' /></dd>
		<dd>{$newsitem->summary}</dd>	
	</dl>";
	}

Hey! This should work

  <?php
    if(count($newsitem->images)) {
      $newsimage = $newsitem->images->first();
      $newsthumb = $newsimage->size(80,80);
    }else{
      // expand '$newsthumb' with some fallback image?
    }
    echo "<dl ... >";

Thanks Adam,

That mostly works but I think I have an issue where I'm calling the image with:

{$newsthumb->url}

How would I alternate that with my fallback image?

Simply; You call 'url' property of image object, whether you have the object initialized (i.e. if page has images), or not (the second part, where you should set fallback). If it's the latter, it will fail, because it seems you don't know how to create fallback image

You have multiple options here; either create some fallback page (e.g. '/fallback'), which wil have the fallback image prepopulated – in this case, in my previous code, the second part will be:

// expand '$newsthumb' with some fallback image?
  $newsthumb = $pages->get('/fallback')->images->first()->size(80,80);

or, more direct approach is to add another variable, e.g. '$newsthumburl', and either populate it if image is found or hardset it to fallback/placeholder image if not:

  <?php
    if(count($newsitem->images)) {
      $newsimage = $newsitem->images->first();
      $newsthumburl = $newsimage->size(80,80)->url;
    }else{
     $newsthumburl = '/path/to/my/fallback_image.png';
    }
    echo "<dl ... {$newsthumburl} ... >";

Thanks so very much. I'm learning all the time with this great system and the generous help of folk like yourself.
