Can you use file_create_url() inside node.tpl.php? Should I assume you can only use it in the template.php?

$img_src = render($content['field_image']);
$bgimage = file_create_url($img_src);

Using the following code, I am only getting public://science-of-rock_background.png from $img_src. Is there any reason why it would be blank?

print $img_src;
print $bgimage;

Edit made to avoid confusion:

In my tpl page for this field I am generating the uri.

field--field_image.tpl.php

<?php foreach ($items as $delta => $item) : ?>
  <?php 
  print $item['#item']['uri']; 
  ?>
<?php endforeach; ?>

I'd first suggest to dpm($img_src) -- You'll need the devel module for that to work. See what is actually inside that field. It's odd that it would be a file path though.

I'd never put logic like that inside a template file anyway. Use a preprocess function anyway:

template_preprocess_node(&$variables) {


}

inside template.php (replace template with your theme name)

  • Interesting. Silly question. How would I directly pull the field into this? render($content['field_image']); doesn't work. Would it be the full array? – tdm Apr 24 '14 at 21:33
  • Another question, on using dpm(). Can you 'only' use it in a function in the template.php? – tdm Apr 24 '14 at 21:35
  • (Cliché -- there are no silly questions!) The field values will be inside that $variables array. Use dpm($variables) and hopefully you'll see a yellow box that contains the values of that array. 2. You can use dpm anywhere there is a messages region in your theme. An alternative is kpr. That basically does the same thing but injects the debug text at the top of the page. – kevin.coyle Apr 24 '14 at 23:23
  • Got it. 1 and 2 both worked. Thanks a ton for the help! – tdm Apr 25 '14 at 21:25

file_create_url takes a uri, such as public://science-of-rock_background.png

The revised:

$img_src = $content['field_image']; $bgimage = file_create_url($img_src);

Would work if your field is only returning the URI.

And, for best practices, should set that up in preprocess_node, otherwise will work in node.tpl.php

  • The content of the field is available as $field_image; $content['field_image'] is always a rendering array, which is not what the OP wants. – kiamlaluno Apr 24 '14 at 2:26
  • The file's URI is available within the render array, and the code was shortened based on OP stating: I am only getting public://science-of-rock_background.png from $img_src – Matt Glaman Apr 24 '14 at 2:32
  • Sure, it is available, but you need to access it more directly than with $content['field_image']. It is then an error to use the render array when the field content is already available. – kiamlaluno Apr 24 '14 at 3:47
  • And you are completely correct. Was trying to keep in context of original post - I know this is exactly how i started, and then moved into proper format – Matt Glaman Apr 24 '14 at 3:48

The error is that render() returns HTML output, while file_create_url() is expecting a URI or a file path. In node.tpl.php, the content of a field is available as variable; so, the field you are trying to access is available as $field_image, basing on the following note.

Field variables: for each field instance attached to the node a corresponding variable is defined; for example, $node->body becomes $body. When needing to access a field's raw values, developers/themers are strongly encouraged to use these variables. Otherwise they will have to explicitly specify the desired field language; for example, $node->body['en'], thus overriding any language negotiation rule that was previously applied.
