I want to build a fancy headline container which - you'll never guess it - contains the title of each page displayed.
In Django you can either create a variable in every view which is passed to the layout page or define a block which is filled with content on the content page.
Its not such a nice solution copy and pasting my fancy header on every page of my application just to put my page title in. I'd prefer to put the headline container in my layout page and use my $title variable to set the title within the container.
I found a solution for static variables here but I need a dynamic variable because the title is different for every page.
My question: Is there an easy way to pass the $title variable which I have on every content page to my layout.phtml?
Thanks!
There is a nice view Helper in ZF for this task. You can define what Title you want to use for your page in your view files.
In your view pages:
//index.tmpl
$this->headTitle("this is my unique title for this page");
In your Layout file :
<title><?php echo $this->headTitle() ?></title>
And more info at: http://framework.zend.com/manual/2.0/en/modules/zend.view.helpers.head-title.html
Ok, the answer is quite simple if you know what to look for. Use the placeholder helper.
//layout.phtml
<?php $this->placeholder('foo')->set("Some text for later") ?>
and
//myview.phtml
<?php
echo $this->placeholder('foo');
// outputs "Some text for later"
?>

I want to insert from Controller in the end of some view's code like this
"<"script> setInterval(function(){ alert("Hello"); }, 3000);"<"/script>
How to do this?
There's multiple ways to do this in PhalconPHP. Depending on your needs, you might be able to get away with just:
$js='setInterval(function(){alert("Hello");},3000);';
$this->view->js=$js;
then from the view, you'd do:
<script><?php echo $js; ?></script>
If you need to insert the JavaScript into your top-level index.phtml from a nested view, the way to accomplish this is to first edit your ControllerBase.php and define a new collection:
$this->assets->collection('footer');
Then add a reference to the footer collection from your top-level index.phtml file:
<body>
<?php echo $this->getContent(); ?>
<?php $this->assets->outputJs('footer'); ?>
</body>
You could also use output('footer') instead if you just wanted a dynamic place in the document you can insert HTML of any kind. Note that a collection specializes in managing CSS and JavaScript, hence the outputJS method, but can also handle miscellaneous code for other purposes. There's also outputCSS, outputInlineJs, outputInlineCss, outputInline, and simply output. See:
http://php-phalcon-docs.readthedocs.org/en/latest/api/Phalcon_Assets_Manager.html
Then edit your ControllerBase.php to initialize the asset to an empty collection:
$this->assets->collection('footer');
(if you skip this step, your code will see errors if your top-level index.phtml file tries to output the contents of a non-existent collection if you never write to it, so always initialize it to an empty collection so it exists.)
Finally, from the controller you want to use, you'd do:
$this->assets->collection('footer')->addInlineJs($js);
where $js is your inline JavaScript, excluding the script tags.
You can also work with external JavaScript files by using
->addJs(...). By default it will be relative to your application directory, inserting a / automatically. If you dislike this functionality, you can set the second parameter to false then it will allow you to specify your own leading / or point your resources at another domain.
As far as the assets you can add to a collection, see:
https://docs.phalconphp.com/en/latest/api/Phalcon_Assets_Collection.html
Note that you can also add assets to your collection from your view and the changes would still appear in your top-most index.phtml.
It is also worth noting that you don't need to actually use collections, you can simply use assets without a collection, but I think collections are more powerful in that you get to name them so there's another level of separation in case you need to manage more than one kind of collection of data.
In terms of what you're trying to accomplish, if you're just trying to give the user a message, this is what Phalcon's flash is for, not to be confused with Adobe Flash which is for playing videos. Phalcon's flash is for flashing messages to the user such as error messages, or your form submit successfully kind of messages. See:
https://docs.phalconphp.com/en/latest/reference/flash.html
If you're still confused what flash is, a demo of what it's output is, you can see in the screenshot here: https://docs.phalconphp.com/en/latest/_images/invo-2.png
That is output of ->error(...) and ->notice(...) respectively. The flash component keeps track of a collection of the messages you'd like to show the user. Then once you're ready to display them to the user you'd call:
<?php echo $this->flash->output(); ?> from your view. It is best to make this call from your top-most template or a template which is always included in your top-most template such as your navigation template so you can easily display messages to the user. It is also useful for debugging. I'd suggest using twitter bootstrap for styling the flash output.

I have a login form in my header section of the website. If user is logged in than insted of the login form user profile details will be shown. The question is how to separate header footer and content into different views and call them from one controller? Or maybe there is another solution...Thanks for help.
In your header view you could write something like this.
<?php if(Yii::app()->user->getId()): ?>
<?php $this->renderPartial('//world/_header_user')); ?>
<?php else: ?>
<?php $this->renderPartial('//world/_header_guest')); ?>
<?php endif; ?>
Using the Model-View-Controller (MVC) design pattern, the look of a Yii-based site is naturally controlled by the View files. These files are a combination of HTML and PHP that help to create the desired output. Specific pages in a site will use specific View files. In fact, the View files are designed to be broken down quite atomically, such that, for example, the form used to both create and edit an employee record is its own file, and that file can be included by both create.php and update.php. As with most things in OOP, implementing atomic, decoupled functionality goes a long way towards improving reusability. But the individual View files are only part of the equation for rendering a Web page. Individual view files get rendered within a layout file. And although I’ve mentioned layouts a time or two in my writings on Yii, it’s a subject that deserves its own post.
To be clear, layouts are a type of View file. Specifically, whereas other View files get placed within a directory for the corresponding Controller (i.e., the SiteController pulls from views/site), layout files go within views/layouts. But while the other View files are associated with individual Controllers (and therefore, individual pages), layouts are communal, shared by all the pages. Simply put, a layout file is the parent wrapper for the entire site’s templating system. I’ll explain

The easiest way is probably to use a different layout, which you just switch on login. If not, showing partials / components based on Yii::app()->user->isGuest also works well.
Your default generated Yii application has a parent Controller in protected/components/Controller.php.
If you need to access additional parameters in layout, add public properties to Controller, set them in your child controller, and use them in your view/layout files.
the site that I'm working at is designed in a such way that CSS class is set for the tag on all the pages and the css classes used are different for all pages. Each page has common elements such as a header, a footer and a nav bar. I'd like to set up a single page template and include all common elements there but the body tag stands in the way. Is there a way to control a template from a content page? I know I can specify a code behind for content pages but i can't rely on content authors to enter it correctly each time they add a page. My current thinking is to set up multiple page template, one for each css class that is referenced in the body tag and put the common page elements into user controls. This is less than ideal because I will end up with lots of mostly identical templates and my user controls would not be editable easily. I guess I would have to use shared content items and such making the content authors hunt all over the site. I would have been much simpler to update the common header in a single page template.
Can someone please suggest a way?
I submitted a reply in the Sitefinity forums where you originally posted this, but just in case you check here first I'll ask the same question: how is the css class for body determined?
if it can be done programmatically you can use the code-behind of the Master Page for the template to set it so that it's handled automatically.
If this won't work, tell me more about how the css class is assigned and I will try to come up with an alternative.
hope this is helpful!
I'm new to drupal,
I'm getting users favorite color from cck color picker then I want to set it to the background of the profile page. Profile page i created using views. I tried to do it from crating view tpl file but no luck is any way to do that task please direct me
this is obviously not complete code, as you need to figure out how to call the field data. I haven't tested this, but in theory this should work. Add this to the .tpl.php file, and see if it works.
<?php
header('Content-Type: text/css');
/*replace cckmachinename and fieldmachinename with actual code*/;
$user_color = cckmachinename -> fieldmachinename
?>
some selector {
background-color: <?php echo $user_color; ?>;
}
Hope this helps!
I have a component with several categories of games and I want to display a different banner depending on the category. I need the banner (and link) to be customizable so it's not simply a case of showing categoryX.jpg or whatever.
I saw this Joomla help page on another question, but it only seems to display a module type, not one specific module. I'd like to use various mod_custom modules and display the one appropriate to the category (I can store each module's ID if necessary).
Any ideas?
This can be done in a 2 step process:
Use the "Load module into article" plugin to allow yourself to access the module using a plugin call like:
{module [*mod_id*]} // where *mod_id* is the module id
Now that you can call a plugin to put your module anywhere, you now need to go to the view code of your/a component you wish to add the module to and add this code:
echo JHTML::_('content.prepare', '{module [*mod_id*]}');
Please see this link - http://www.alltogetherasawhole.org/group/developers/forum/topics/running-joomla-content-plugins - regarding point number 2. I was trying to do the same thing and I found it didn't work, and the reason for this was a comment you can find on the page link above:
"I noticed that some plugin actually expect option=com_content for them to process onPrepareContent properly, so you might actually want to "fool" them by callin JRequet::setVar and restoring the correct values after the trigger."
If you would like to show module within PHP code then use this code, it's worked for me :
<?php echo JHTML::_('content.prepare', '{loadposition position-2}'); ?>
If you want to show module inside html content then just put this code where you want to show module.
{loadposition position-2}
It loads all modules which are assigned to position-2.
You can also use the Joomla Module Renderer
$doc = JFactory::getDocument();
$renderer = $doc->loadRenderer('modules');
$position = 'custom_position_name';
$options = array('style' => 'raw');
echo $renderer->render($position, $options, null);
Just a heads up, Along with being assigned the module position, that module also has to be set to "Display on All pages".
Joomla has this functionality built in. You can use the {loadposition XX} command within your content items. You can specify custom module positions that do not appear in your template to insure that you have the correct module in the correct article.
http://docs.joomla.org/How_do_you_put_a_module_inside_an_article%3F
You could create a new module?
If each category appears in the querystring (catid=X) then you could take a similar approach to https://support.pillwax.com/open-source/doku.php?id=joomla:header_image.
Alternatively, that link might actually do it for you.
