I would like to move portions of code from template files to custom module. But i fail do find descriptive guide for such task. Idea is to migrate complex db queries and EntitiyFieldQuery out of the tpl.php files. For example:

$query = new EntityFieldQuery();
$entities = $query->entityCondition('entity_type', 'node')
  ->propertyCondition('type', 'predmet_clanak')
  ->fieldCondition('field_taxonomy_choose', 'value', 1 , '=')
  ->fieldCondition('field_vrsta', 'tid', 241);

$result = $query->execute();    
$nodes = entity_load('node', array_keys($result['node']));
foreach ($nodes as $node) {
  print ('<div class="putujuci-wrapper"><div class="putujuci">');    
  print drupal_render(node_view($node, 'teaser'));
  $nodelink = ltrim(url('node/' . $node->nid), "/");
  print ('</div>');     

  $imageLink = '<img src="' . $base_url . '/sites/all/themes/profil_edu/css/images/vise-button-static.png" width="55" height="28" border="0" class="img-swap">';
  print l($imageLink, $nodelink, array('query' => array('iframe' => 'true', 'width' => '800', 'height' => '700', 'format' => 'popup'), 'attributes' => array('class' => t('colorbox-load gumb')), 'html' => TRUE));
  print ('</div>');     
}

This code fetches collection of nodes (when conditions are met) in custom tpl.php file. I have been advised not to create complex queries in tpl files, but do not know yet best practices to do so.

I guess, module will firstly need to know context where i want this to occur? And after i do this in the module, do i need to pass this to the template.php first?

    Is this like a block? a page? or something else? How would you best describe where this content maps to something in drupal?

  • It is itended to show in various tpl.php pages. I have few content types, and i display node collections depending on context (im detecting that context by examining taxonomy field that was set for that node). More detailed, those are sliders with Node collections in it.

I think you should go through the module developer guide.

You can use hook_preprocess_HOOK() in your template.php. So if your code was placed in the node template, the hook will be themename_preprocess_node($vars) and then you can check for a particular node type and create a variable like $vars['custom_variable'] = 'the query stuff'; and this variable will be available in your template.

  • Thanks for this, i already looked into that, but i need advice in my case, i already know how to create module (files etc) but i am puzzled how to make logic chain for the code.

    hook_preprocess_HOOK() will allow you to inject variables in your templates. Or replace existing value with your own. You also have hook_process_HOOK(). See documentation of the theme() function for all the available hook and their order. Commented Aug 28, 2012 at 20:10
  • Thanks for further suggestions! I hope with little documentation examination i will be able to migrate my php voodoo where it belongs :D
