What I want to do is have one page that lists some data from my database (the data is separate from Bolt).
I've looked into extensions but I don't see any way to make a "page" as such, only create "snippets". But snippets don't display actually in the content area, you can only add them right after the <body> tag or in the <head>. Also it looks like they appear on every page, not on page.
Is it possible to run some custom PHP code on a page to fetch some data from a database and display it? Does anyone have a bare-bones example?
This is the sort of thing that extensions are for, but snippets are not what you want.
Bolt is a Silex application and comes with a Doctrine DBAL provider, so you can just use $app['db'] to give you access to the \Doctrine\DBAL\Connection object that you can use to query your table, e.g.
$resultArray = $this->app['db']->createQueryBuilder()
->select('*')
->from($tableName)
->where('my_column_1 = :my_column_value_1')
->andWhere('my_column_2 = :my_column_value_2')
->orderBy('my_column_3', 'DESC')
->setParameter(':my_column_value_1', $value1)
->setParameter(':my_column_value_1', $value2)
->execute()
->fetch(\PDO::FETCH_ASSOC);
You can then do what you want with the data, and render that in Twig as you see fit.
There is a tonne of documentation on creating extensions with Twig functions that you can put in a template {{ my_twig_function() }}

I am trying to create a module which has both frontend and backend functionality. Like I need to ask for the city in the home page when the store loads. And all the available cities are entered/managed in backend admin panel.
Before I used to write for only backend things, frontend seems little confusing.
There is a design folder which is completely for theme development.
All the example are little different(https://www.mageplaza.com/magento-2-module-development/,http://inchoo.net/magento-2/how-to-create-a-basic-module-in-magento-2/]2), they have routes.xml, where route_id, and all are defined, but here I don't need any extra route. Need some additional tweaks in frontend pages.
I created module V_name/M_name/adminhtml/block controllers etc view ...
Guide me how to create a module, which has both front end and backend connection, cities should be entered in admin, they should show on the frontend homepage.
For now, I only managed to edit home page content CMS page by adding some HTML which shows a popup with a dropdown for cities when the page loads.
Since you already have the back-end figured out I will focus on front-end. Also, since all you need to do is populate a list that you already have created this should be easy. I did something like this before and I found it easier to just use JSON to query a list of, in your case the cities, and populate the drop down. I don't believe this is the most 'MVP/proper' way to go, but it is less work then the other ways. (At least for me it is. I always prefer the JavaScript option since it allows for easy future page customization.)
To use the JSON method you need to create a Block with a method like the one below. You will see that you will also have to create a Resource Model (I'm not going to go over creating the Resource Model or the details of Blocks since there are much better resources than me already online that will go into every single detail you need.). Once this is complete you can access the data straight from the .phtml page in an easy to use JSON array.
First you need to make sure you are now structuring your Modules properly. The new Block below should be in a structure like this...
app/code/<VENDOR>/<MODULE>/Block/Wrapper.php (or whatever you name it)
The admin Blocks should be in the structure below, which it sounds like you are already know how to do.
app/code/<VENDOR>/<MODULE>/Block/Adminhtml
Create your Block and add a method to create a JOSN array like below...
public function getCityList()
{
$city_array = array();
/** #var \<VENDOR>\<MODULE>\Model\ResourceModel\City\Collection $collection */
$collection = $this->_cityCollectionFactory->create();
$collection->addFieldToFilter('active','1')->addFieldToSelect(['city_id', 'city']);
$collection->getSelect()->order(array('city ASC', 'city_id ASC'));
$count = 0;
foreach ($collection as $model)
{
$city_array["$count"] = $model->getData();
$count++;
}
return \Zend_Json::encode($city_array);
}
FYI... The foreach loop in the code above is weird and uses $count because I needed to do some tricky things to get something to work.
Then you can create the Block in your .phtml file to access the data via javascript.
<?php
$block_obj = $block->getLayout()->createBlock('<VENDOR>\<MODULE>\Block\Wrapper');
?>
<script type="text/javascript">
window.citylistJson = <?php echo $block_obj->getCityList() ?>;
</script>
For my Codeigniter site, I started by making a view for each controller situation. This was impractical, as it would require going back to the code for each to make a change. So I changed approach and operated on a 'default' controller with optional fields. I then thought I could load special views as needed into it.
I put together this view with optional fields with fields for $title, $search_bar on/off etc. However, now came the content area. I was able to load more views into this default view using:
$data['content_views'][]='blocks/login';
$this->load->view('default/a', $data);
and in the 'default'view:
if(isset($content_views)&& (is_array($content_views)))
{
foreach($content_views as $content_view)
{
$this->load->view(&$content_view);
}
}
(and that works fine)
Two questions:
Am I making things to complex? Is this an accepted way of doing this? Or have I misunderstood the functioning of a view and how they are intended to work?
I want a way to mix the $content_view, i.e. a block of text, then a view. I'm not quite sure as to how to proceed. Say I want a message first, then a view, then more text. This method will only accept views.
Can anybody help me create this flexible approach?
Yeah I would say you're making things a little complex. While I may not be following your description well enough to know precisely how to respond, I can tell you how I do it:
First the whole site is run through a template so the header and footer are the container file and all views needed within the site are rendered as page type views - like an article page, a gallery page, etc. Components are loaded and passed to the views as strings:
$content['sidebar'] = $this->load->view('components/sidebar', $data, true);
That last true says to render as string.
Essentially, this means the page views are pretty much html with php echoing out the necessary elements. No views calling other views, which is how I read your example.
CI loads views progressively, so your controller can output like so:
$this->load->view('header', $header_data);
$view_data['sidebar'] = $this->load->view('components/sidebar', $sidebar_data, true);
$this->load->view('content', $view_data);
$this->load->view('footer', $footer_data);
and in content view, handle the sidebar like so:
<?php if(isset($sidebar)): ?>
<nav>
<?php echo $sidebar; ?>
</nav>
<?php endif; ?>
And, assuming you populate those arrays for each view it will render header, then content, then footer. And also render sidebar if it is present.
So combining everything, I'm basically saying you can load in sections in your controllers progressively, passing sub-views as strings to whichever section makes sense. That keeps your view controlling in the controller where it belongs and not in the view files themselves. In my experience, I have not had to write a site that was so complex that this construct wasn't perfectly suitable if the site is planned well.
I'm going crazy with this one. I am trying to change a little bit the pagination style and layout in Joomla. So, I found this file: libraries\joomla\html\pagination.php but I know that pagination is overridden by this file: templates\gk_yourshop\html\pagination.php. Yet, if I modify something in gk_yourshop\html\pagination.php, I can't see the change in the pages. Does joomla cache templates and I have to re-load them (like phpBB)?. I don't understand.
I tried to check if writePagesLinks is called from joomla\html\pagination.php with this:
function getPagesLinks()
{
echo "test";
global $mainframe;
and I can't see the message. I also did this in the other pagination.php file and it's just like I can delete them and it doesn't matter. Can you help me? Thanks!
Looks like I changed it here some time ago:
\libraries\joomla\html\pagination.php
But, that is system file, so i just make a "hotfix" of it.
In Joomla 3.x you can create pagination override from Extensions > Templates > Default Template > Create Overrides > Layouts > Pagination.
The override files are created in "Default Template" "html\layouts\joomla\pagination" folder.
You can edit the override files as per your needs.
Where are you getting WritePageLinks from? That's not one of the supported methods.
http://docs.joomla.org/Understanding_Output_Overrides#Pagination_Links_Overrides
There are four functions that can be used:
pagination_list_footer
This function is responsible for showing the select list for the
number of items to display per page.
pagination_list_render
This function is responsible for showing the list of page number links
as well at the Start, End, Previous and Next links.
pagination_item_active
This function displays the links to other page numbers other than the
"current" page.
pagination_item_inactive
This function displays the current page number, usually not
hyperlinked.
[edit]
You may also want to look at Protostar as an example.
I used Joomla 1.5 for a site that I developed for a gaming company. Part of the site consists of a character generater for the game that they developed. The issue is that users want to be able to print the character sheets off, without having the Joomla template surrounding it.
As for the specifics, I have the directphp extension installed, and the entire generator is written in PHP (with a little JavaScript to handle things that PHP can't). As the generator spans several dozen page calls, it made sense to store everything in $_SESSION. All of this works correctly. In an attempt to make the final sheet printer friendly, I tried redirecting the user to a page outside of Joomla (though on the same server, and even within the same folder) but I cannot access the $_SESSION data from this new page.
I have seen several posts (a few on this site) that point to loading the Joomla Framework and accessing it that way, which I have tried, but the data that I was looking for does not appear to be contained there. Has anyone come across this problem before, or know how to get to that data?
You are making this WAY harder than it needs to be. You don't have to write any additional code to accomplish what you are trying to do. In order to print our the component output without all of the Joomla template, you just append ?tmpl=component to your URLs and Joomla will display only to component output without any of the template. If you want to give it a custom stylesheet or anything special, you can also add in a template override by adding a file named component.php in your template folder.
In order to control the CSS per page, you can add Page Class Suffixes in the menu items. Then add this code to index.php so you can use them.
Somewhere in the head add this:
$menu = &JSite::getMenu();
$active = $menu->getActive();
$pageclass = "";
if (is_object( $active )) :
$params = new JParameter( $active->params );
$pageclass = trim($params->get( 'pageclass_sfx' ));
endif;
Replace your body tag with this:
<body id="<?php echo $pageclass ? $pageclass : 'default'; ?>">
Any page that you do not specific a Page Class Suffix for will use default as the body ID, any that you do will use what ever you specify.
I'm trying to access a Drupal View through my template and want to iterate through it's results to show data. Something simple, like:
foreach($fields as $field) {
echo $field['name_of_the_field'];
}
So i can have full control of my view display inside my teplate. And, of course, being easier to build my template in Drupal. Any help? Thanks in advance.
You can export a views template and then access what you need through that.
Go to the views, and under the 'Basic Settings' section. Click on the 'Theme: information' link.
Then, you'll see a list possible template links.
Click on one of those links and you'll see textarea with the template. Copy the template to a file with the same name as the link name and put it in your themes folder.
Anyway, once you have the proper template, you'll see what object you can iterate over.
