How to get the value of a node field?

Question

In node.tpl.php I am trying to get the raw value but the problem is that when I use render:

<?php print render($content['field_price']);?>

it does not just return field_image value but formats and outputs the whole image.

I need a way to get only the field's raw value. How can I achieve this?

Answer 1

To get the real value and not a themed one...

You can use http://api.drupal.org/api/drupal/modules!field!field.module/function/field_get_items/7

 $my_field_items = field_get_items('node', $node, 'field_my_field');

Or use Entity API module and entity_metadata_wrapper

 $node_wrapper = entity_metadata_wrapper('node', $node);
 $field_val = $node_wrapper->field_test->value();

Answer 2

In a node template, for raw values you can access the $node object.

<?php print $node->field_price; ?>

If you need to see the structure, can do <?php print_r($node); ?>.

Also, if this is for a specific content type you should use a variation of node.tpl.php instead of node.tpl.php itself or else it will try to display fields that are non-existent on other content types.

Answer 3

enable Devel module and in node-{content-type}.tpl.php use

<?php print dsm($node); ?>

on top of code.

you can see all $node fields in readable format
