Output only the URL of article image?

How can I output nothing but the URL of an article image? Just what’s in the IMG tag’s src=”“ attribute, nothing more. I’m not averse to using plugins, hacks, or even Deep Magic from Before the Beginning of Time…

Re: Output only the URL of article image?

Not sure if this falls under hacks or Deep Magic, but…

If you have filled in a complete URL in your article image field, it’s easy:

<txp:php>
  global $thisarticle; 
  echo $thisarticle['article_image'];
</txp:php>

If you’re using just the article ID… well, not that complicated either:

<txp:php>
  global $thisarticle, $img_dir; 
  $image = intval($thisarticle['article_image']);
  $ext = safe_field('ext', 'txp_image', 'id = '.$image);
  echo hu.$img_dir.'/'.$image.$ext;
</txp:php>

Although if all your images are in the same format and have the same extension, say ‘.jpg’, you could simplify that to:

<txp:php>
  global $thisarticle, $img_dir; 
  $image = intval($thisarticle['article_image']);
  echo hu.$img_dir.'/'.$image.'.jpg';
</txp:php>

PS. none of the above solutions is tested.

Re: Output only the URL of article image?

Wow, comprehensive answer. :) Thanks! Since I posted this, though, I figured out a solution, using the upm_image plugin (<txp:upm_article_image><txp:upm_img_full_url /></txp:upm_article_image>). But it’s certainly good to see that the solution wasn’t some simple thing staring me right in the face! ;)
