How to use a field value in Template.php Im sure this is an easy question, just not for me because of lack of experience with the Drupal preprocess hooks. I am removing the standard "Read More" links from my content. I want the ability to replace them with a css button. I can do that, the tricky part come when I want to use a FIELD from the CONTENT TYPE, as the name for the button. 

function bootstrap_preprocess_node(&amp;$variables) {

 unset($variables['content']['links']['node']['#links']['node-readmore']);

   $variables['newreadmore'] = t('&lt;span class="newreadmore"&gt; &lt;a href="!title" class="btn       
  btn-info" &gt;'.$readmoretext.'&lt;/a&gt; &lt;/span&gt;',
   array(
    '!title' =&gt; $variables['node_url'],
  )
);
}


My question is how can i HOOK into the node and retrieve the field for my variable $readmoretext

Thanks!
You can find the node object in $variables['node'], and from there you can use the field_get_items() function to extract your field value:

$node = $variables['node'];

// field_get_items() always returns an array, even if the field is limited to one value
$field_items = field_get_items('node', $node, 'field_name');

// Get the value from the first item in the array (if that's the one you need)
$title = $field_items[0]['value'];
