I hope the title is ok. I've seen many discussion here about using custom templates in a module when using views, but i lack a piece of answer : how to use specific variables from an entity in that template ?
Backgound information about my problem : I'm making a module 'youtube2drupal', using a custom table 'youtube_video', having some fields (one of them is 'vhash', the video hash in youtube). With this table i create an entity 'ytv'. I added this key to mymodule_entity_info() to use with Views : 'views controller class' => 'EntityDefaultViewsController', Then to test it i create a view displaying one video with all its informations => everything is ok.
Everything BUT, to display the video, i need a iframe and i cant't use the rewrite of the output for the 'vhash' field i added in the view field.
The code needs to be :
<iframe width="560" height="315" src="//www.youtube.com/embed/<?php print $vhash; ?>" frameborder="0" allowfullscreen></iframe>
In the suggested template for the view, there is one i can use : views-view-field--vhash.tpl.php
I don't want to override any theme : i'd like to have all the code in my module. So I created this file 'views-view-field--vhash.tpl.php' in my /templates dir in my module.
I looked for solutions to tell Drupal to use it:
First, I've checked this lead, with hook_theme_registry_alter() https://swsblog.stanford.edu/blog/using-templates-custom-drupal-module
and i tried
function youtube2drupal_theme_registry_alter(&$theme_registry) {
dpm($theme_registry);
$module_path = drupal_get_path('module', 'youtube2drupal');
$theme_registry['views_view_field__vhash']['theme path'] = $module_path . '/templates';
$theme_registry['views_view_field__vhash']['template'] = 'views-view-field--vhash';
}
but the 'views_view_field__vhash' key doesn't exists, so it seems this is not the right solution to register this template.
Then i saw this discussion https://stackoverflow.com/questions/5305114/drupal-7-how-to-load-a-template-file-from-a-module#answer-5307126
so i tried
function youtube2drupal_theme($existing, $type, $theme, $path){
return array(
'views_view_field__vhash' => array(
'variables' => array('vhash' => NULL),
'template' => 'views-view-field--vhash',
'path' => drupal_get_path('module', 'youtube2drupal') . '/templates'
)
);
}
function youtube2drupal_page(){
// some code to generate $vhash variable : this is where i'm stuck !
return theme('views_view_field__vhash', array('vhash' => $vhash));
}
=> This seems the right way to register correctly the template but i don't know how to set vhash variable in this context :
i want to use something like $myentity->vhash.
but i can't use $myentity = entity_load('ytv', array($entity_id)); because $entity_id is not defined in youtube2drupal_page() context.
Am i on the right track using youtube2drupal_theme() / youtube2drupal_page() to register the template for the module ? If so how can i tell Drupal to use the right value of vhash for this entity i created ?
----- Edit ------- I tried the preprocess function : I changed :
function youtube2drupal_theme($existing, $type, $theme, $path){
return array(
'views_view_field__vhash' => array(
'template' => 'templates/views-view-field--vhash',
'file' => 'includes/youtube2drupal.theme.inc',
'base hook' => 'views-view-field',
)
);
}
and added in the includes/youtube2drupal.theme.inc :
function youtube2drupal_preprocess_views_view_field__vhash(&$variables, $hook) {
dpm($variables);
$variables['vhash'] = $variables['view']->result[0]->youtube_video_vhash;
//sets the right value into $vhash, but only for the first element
}
This doesn't "break" the site, but obviously the $variables['view']->result[0]->youtube_video_vhash; is valid only for the first element in the list. If i want to display 2 or more videos, the keys for $variables['view']->result should be 1, 2, ...
So, how can i dynamically set this vhash variable with the correct value ? Is it possible that way ? Thanks in advance.
