#Themeing

Hide $title on Event pages

  function THEME_preprocess_page(&$vars) {
  $vars['show_title'] = !isset($vars['node']) || (isset($vars['node']) && $vars['node']->type !== 'event');  
}

Allow the theme to find template files for content types

function THEME_preprocess_page(&$vars) {
  
  // Do we have a node?
  if (isset($vars['node'])) {

    // Refernece suggestions.
    $suggests = &$vars['theme_hook_suggestions'];

    // Get path arguments.
    $args = arg();
    // Remove first argument of "node".
    unset($args[0]);

    // Set type.
    $type = "page__type_{$vars['node']->type}";

    // Bring it all together.
    $suggests = array_merge(
      $suggests,
      array($type),
      theme_get_suggestions($args, $type)
    );

    // if the url is: 'http://domain.com/node/123/edit'
    // and content type is 'blog'..
    //
    // This will be the suggestions:
    //
    // - page__node
    // - page__node__%
    // - page__node__123
    // - page__node__edit
    // - page__type_blog
    // - page__type_blog__%
    // - page__type_blog__123
    // - page__type_blog__edit
    //
    // Which connects to these templates:
    //
    // - page--node.tpl.php
    // - page--node--%.tpl.php
    // - page--node--123.tpl.php
    // - page--node--edit.tpl.php
    // - page--type-blog.tpl.php          << this is what you want.
    // - page--type-blog--%.tpl.php
    // - page--type-blog--123.tpl.php
    // - page--type-blog--edit.tpl.php
    //
    // Latter items take precedence.
  }
  
}

Call in a VIEWS block in to page.tpl.php - D7

<?php
  // To get the 'BLOCK NAME' check the 'configure' URL on admin/structure/block 
  $block = module_invoke('views', 'block_view', 'BLOCK NAME');
  print render($block['content']);
?>

Views

Contextual Filters PHP - filter view by same text value

if (arg(0) == 'node' && is_numeric(arg(1))) {
  $node = node_load(arg(1));
return $node->FIELD_NAME['xxx'][0]['value'];
} else {
  return FALSE;
}
