How to print a CCK image field alt text in a node template?

Question

I'm trying to add the alt text from a cck image field in a Drupal 7 node template. Getting the image style url is done, but I can't figure out how to just get the alt text. This is what I have

<img src="<?php print image_style_url('160x160', $node->field_image['und'][0]['uri']); ?>" alt="????" class="thumbnail" />

How does one just output the alt text?

Answer 1

If you install the Devel module, you'll be able to use:

<?php dpm($node); ?>

It will provide all available fields that you could use. Another method might be to use theme('image') to help clean up your image theming.

Answer 2

A print_r will give you idea. In your case it will be

$node->field_image['und'][0]['alt']

ie: <img src="<?php print image_style_url('160x160', $node->field_image['und'][0]['uri']); ?>" alt="<?php echo $node->field_image['und'][0]['alt']; ?>" class="thumbnail" />
