Can I add new nodes to mustache template at run-time in PHP? Let's say below is a code where ProductDetails will contain few single products:
{{#ProductDetails}}
{{#SingleProduct}}
{{OldDetail}}
{{/SingleProduct}}
{{/ProductDetails}}
I want to add a new node like {{NewDetail}} just after {{OldDetail}} through some function in run-time(i.e just before I am compiling the template as these templates have been shipped to customers in such a way that only code to compile can be changed but not the template)? I don't want to do string manipulation(customers created few new templates with above parameters present at least but the spacing may change & few new entries can be added by them around nodes). Does mustache library provide any functions for that?
If I were you, I will try Lambdas.
Template.mustache will be like this:
{{#ProductDetails}}
{{#SingleProduct}}
{{OldDetail}}
{{/SingleProduct}}
{{/ProductDetails}}
And codes will be like:
$Mustache = new Mustache_Engine(['loader' => new Mustache_Loader_FilesystemLoader($YOUR_TEMPLATE_FOLDER),]);
$Template = $Mustache->loadTemplate('Template');
$OriginalOldDetail = '<h1>this is old detail</h1>';
echo $Template->Render([
'ProductDetails' => true,
'SingleProduct' => true,
'OldDetail' => function($text, Mustache_LambdaHelper $helper){
// Render your original view first.
$result = $helper->render($text);
// Now you got your oldDetail, let's make your new detail.
#do somthing and get $NewDetail;
$NewDetail = $YourStuff;
// If your NewDetail is some mustache format content and need to be render first.
$result .= $help->render($NewDetail);
// If is some content which not need to be render ? just apend on it.
$result .= $NewDetail;
return $result;
}
]);
Hope that will help.

I'm stuck trying to get joomla full article to render in a tab. The tab is working. I just can´t render the article content. This is where I am now.
This is helper.php
public static function getArticle($articleId)
{
JModelLegacy::addIncludePath(JPATH_SITE.'/components/com_content/models', 'ContentModel');
$model = JModelLegacy::getInstance('Article', 'ContentModel', array('ignore_request' => true));
$article = $model->getItem((int) $articleId);
$fullarticle = $item->fulltext;
$itemsHtml = '<div>'. $fullarticle .'</div>';
return $itemsHtml;
}
And this is in default.php
...code...
else if ($list_of_tabs['use'][$i][0] == 'article'){
echo '<div class="tab-pane '.$active.'" id="'.$i.$rid.'">'.
modJpTabsHelper::getArticle($list_of_tabs['article'][$i], $params) .
'</div>';
}
...code...
If you need more info. Don't hesitate to ask.
What are you trying to achieve: to write your own Joomla! extension which displays articles in a tab or you just need to display your J! articles in a tab?
If it's a latter, then there are already some nice and free (as in a "free bear") add-ons written just for that.
You are trying to use the model part of an MVC as a thing to render.
You should use the MVC system - using a controller to gathering the model and the view, and then you can render the model with the attached view, via the controller.
So you use something like (I've not tested this - you will need to correct it).
$filter=array('id' => $i->query['id']);
$options=array('filter_fields' => $filter,'ignore_request' => true);
$ctl = new ContentModelController();
$view = $ctl->getView( 'Article');
$model = $ctl->getModel( 'Article','',$options);
you may need to set params from application, eg..
$model->setState('params', JApplication::getInstance('site')->getParams());
then continue
$view->setModel( $model, true );
$result = $view->display();
Make sure that you have JLoader::import'ed any classes/classpaths - j. tends to fail silently if they aren't found, which can be difficult to trace.
Sorry, it's only a partial solution - but hopefully it may put you on the right track.
Here was the problem:
$fullarticle = $item->fulltext;
Article object from model was in variable $article not $item:
$article = $model->getItem((int) $articleId);
So getting property fulltext from article object should be:
$fullarticle = $article->fulltext;
So this is the problem I am running into. If I have a comment object, I want to create a renderable array that is using the display settings of that comment. As of now this is what I have:
$commentNew = comment_load($var);
$reply[] = field_view_value('comment', $commentNew, 'comment_body', $commentNew->comment_body['und'][0]);
Which works fine because I dont have any specific settings setup for the body. But I also have image fields and video embed fields that I need to have rendered the way they are setup in the system. How would I go about doing that?
Drupal core does it with the comment_view() function:
$comment = comment_load($var);
$node = node_load($comment->nid);
$view_mode = 'full'; // Or whatever view mode is appropriate
$build = comment_view($comment, $node, $view_mode);
If you need to change a particular field from the default, use hook_comment_view():
function MYMODULE_comment_view($comment, $view_mode, $langcode) {
$comment->content['body'] = array('#markup' => 'something');
}
or just edit the $build array received from comment_view() as you need to if implementing the hook won't work for your use case.
I have just started working with Mustache template engine. I am currently using PHP implementation of it (https://github.com/bobthecow/mustache.php/wiki). I am using helpers to manipulate the way data is rendered.
$data = array("name" => "abhilash");
$template = "Hello {{name}}, {{#bold}}Welcome{{/bold}}";
$m = new Mustache_Engine(array(
"helpers" => array(
"bold" => function($content) {
return "<b>$content</b>";
})));
$html = $m->render($template, $data);
With the help of this I am able to render 'Welcome' with bold font. I would like to know if it is possible to manipulate $data with the help of helper function. For example if the template is like below and I have a helper function registered as dataSource, I would like to use it to collect some data (say key-value pair) from datasource_func_name() and append it to $data.
{{#dataSource}}datasource_func_name{{/dataSource}}
Hi {{name}}
That's normally not how you would use helpers. However, Mustache basically expects a data souce, so why not inject it directly?
$html = $m->render($template, $dataSource);
I am experimenting with kostache, "mustache for kohana framework".
Is there any way I can use simple PHP functions in mustache template files.
I know logic and therefore methods are against logic-less design principle, but I'm talking about very simple functionality.
For example:
gettext('some text') or __('some text')
get the base url; in kohana -> Url::site('controller/action')
Bobthecow is working on an experimental feature that will allow you to call a function as a callback.
Check out the higher-order-sections branch of the repository and the ticket to go with it.
You could use "ICanHaz" http://icanhazjs.com/
and then you can declare your mustache templates as
<script id="welcome" type="text/html">
<p>Welcome, {{<?php echo __('some text') ?>}}! </p>
</script>
Well, you can do this now with Bobthecow's implementation of Mustache Engine. We need anonymous functions here, which are passed to the Template Object along with other data.
Have a look at the following example:
<?php
$mustache = new Mustache_Engine;
# setting data for our template
$template_data = [
'fullname' => 'HULK',
'bold_it' => function($text){
return "<b>{$text}</b>";
}
];
# preparing and outputting
echo $mustache->render("{{#bold_it}}{{fullname}}{{/bold_it}} !", $template_data);
In the above example, 'bold_it' points to our function which is pasalong withwith other data to our template. The value of 'fullname' is being passed as a parameter to this function.
Please note that passing parameters is not mandatory in Mustache. You can even call the php function wothout any parameters, as follows:
<?php
# setting data for our template
$template_data = [
'my_name' => function(){
return 'Joe';
}
];
# preparing and outputting
echo $mustache->render("{{my_name}} is a great guy!", $template_data); # outputs: Joe is a great guy!

Is there any way to change the layout of a facet?
I know you can create a file in the template dir named: block-apachesolr_search-[field].tpl.php
The problem I am having is that at this stage the html in the block variable has already been created.
Is there any way to change the html or just get the elements of the facet?
Thanks!!
are you talking about faceted search module?
you could overwrite stuff by adding it in your template file or something simmilar, forinstance i had to add the "clear-block" to a div and did it this way:
function themename_faceted_search_ui_facet_wrapper($env, $facet, $context, $content) {
$classes = array(
'faceted-search-facet', // Note: Tooltips rely on this class.
'faceted-search-env-'. $env->name,
'faceted-search-facet--'. check_plain($facet->get_key() .'--'. $facet->get_id()), // Note: Tooltips rely on this class.
'faceted-search-facet-'. ($facet->is_active() && $context != 'related' ? 'active' : 'inactive'),
'faceted-search-'. $context,
);
return ''. $content .''."\n";
}
took a while to find the right function in the module file, but i dont know of any other way.
