In page.tpl.php how do you access fields in Drupal 7?

echo render($content['field_name']);

You could use the image styles thing to get images resized on upload.

The fields are available deeply nested in the $page variable, so I use a simple preprocess function for easier access:

function hook_preprocess_page(&$variables) {
        if (arg(0) == 'node') {
                $variables['node_content'] =& $variables['page']['content']['system_main']['nodes'][arg(1)];
        }
}

Then I can simply render fields like this in the page.tpl.php:

if (isset($node_content) && $node_content['field_introduction']) {
    print render($node_content['field_introduction']);
}

Don't forget to hide() the field in the node.tpl.php, else it will be printed twice.

try this:

if( isset($node) and $node->type=='YOURNODETYPE' )
{
    $x = node_view($node);
    print $x['field_YOURFIELDNAME'] );
}

The following will give you a renderable array so that you can output it in your page.tpl with the image style(picture size) and link if required:

For single image:

$node = node_load($nid);
$output = field_view_field('node', $node, 'field_banner_image', array('label' => 'hidden'));		
$vars['banner'] = $output;		

For multiple images:

$node = node_load($nid);
$image = field_get_items('node', $node, 'field_image');
$output = field_view_value('node', $node, 'field_image', $image[0], array(
  'type' => 'image',
  'settings' => array(
    'image_style' => 'thumbnail',
    'image_link' => 'content',
  ),
));

Then you can:

print render($output);

To take it a step further, you can do a little something in your template.php file to keep the logic out of page.tpl

// this goes in template.php
// check if node type page and then add to $vars array
// declaring $vars['foo'] gives you a $foo variable to use in page.tpl.php

function YOURTHEMENAME_preprocess_page(&$vars, $hook) {
	if (isset($vars['node'])) :
		if($vars['node']->type == 'page'):		
			$node = node_load($vars['node']->nid);
			$output = field_view_field('node', $node, 'field_image', array('label' => 'hidden'));		
			$vars['my_image_field'] = $output;				
		endif;
	endif;
}

So finally, you can easily print your field in page.tpl.php;

if ($my_image_field):
   print render($my_image_field);
endif;

Hope that helps someone.

hi,
I was facing some problem while loading single field in my module file, so I have got it right by this...

<?php

$load_full_node = node_load($nid);
$oh = node_view($load_full_node);
$show_my_field = render($oh['field_restaurant_opening_hours']);
print $show_my_field;

?>

Note: It was a opening Hours module field. But it will work for any field.

This worked great for me, in page.tpl.php:

<?php print render(field_view_field('node', $node, 'field_EXAMPLE)); ?>

HOWEVER: I expect much better from Drupal. Why is there not a handbook for getting these functions? I need the ability to get a field URL or any other native information in it. I have been endlessly frustrated by this type of thing since upgrading to Drupal 7.

I'm not printing variables in page.tpl.php just because I can. I need to theme page templates that are called by URL structure (another function that was confusing to upgrade), and functions like these make it possible.

This last is perect but to make rendering without label?

Your code works well... but give me an error on /user (login) page, this one:

include() (line 65 of /var/wwwroot/x/sites/all/themes/themename/page.tpl.php).
EntityMalformedException: Missing bundle property on entity of type node. in entity_extract_ids() (line 7663 of /var/wwwroot/x/includes/common.inc).

A simple approach to output a field value in page.tpl.php:

  if (isset($node->my_field['und'][0]['value']) && count($node->my_field['und'][0]['value']) > 0){
    $output_field = $node->my_field['und'][0]['value'];

    print $output_field;
  }

(Use <?print print_r($node); ?> or, when using the devel module, <?php dsm($node); ?> to figure out the cascading variables.

Works fine :)

I'm honestly not sure if this is "proper", but it works!

<?php
function THEME_preprocess_page(&$vars) {
  $vars['page_banner'] = '';
  // Get the object and do some other checks based on what you need.
  if (($node = menu_get_object()) && $node->type) {
    // Generate a render array for the node.
    $view = node_view($node);
    // "Create" a new variable for the page.tpl.php.
    // This will expose $VAR_NAME in the page template.
    $vars['page_banner'] = drupal_render($view['field_image_banner']);
  }
}
?>

Then add this to your page.tpl.php:

<?php if (isset($page_banner)) : print $page_banner; endif; ?>
