In Drupal 7 Is there a way for me to insert my block into a region only on certain pages inside of a module code? Or do I have to do that in the gui block list?
I've created a banner module, but want to be able to give the ability to choose the pages it appears on. For starts, it could appear only on the front page. I tried a $is_front check, but I am getting an error that $is_front or $variables are undefined.
This doens't work inside of my block_view() function in my module.
if ($is_front){
$block['content'] = theme('mydata', $banner_node_list);
}
I think your best bet is to use the block GUI to select where it appears. I can't see any benefits to doing it in the code when it's already built in to be honest.

I'm looking to add segment analytics to my JupyterLab extension. No worries if you've never heard of a JupyterLab extension - the best way to think about it: I get control over a single node in the DOM where I can place some HTML, so I'm doing the following:
function Welcome(props) {return <h1>Hello</h1>;}
ReactDOM.render(<Welcome/>, dom_element_i_control)
This all works fine - I'm now looking to add some analytics code to this. For example, I'd like to be able to:
See when my code is rendered
See when someone interacts with my rendered element (e.g. if there was a button in the Welcome function, when the user clicked on it).
However, segment is a JS library that is delivered as a script that you load into a webpage at the top in a string tag like:
<script>
!function(){var analytics=window.analytics=window.analytics||[];if(!analytics.initialize)if(analytics.invoked)window.console&&console.error&&...}}();
</script>
Where would I even put this code? I don't have control over the larger page + HTML, so I'm not sure where I can slap this so I can start using analytics.
Thanks for any information!
My workaround:
Instead of using the above linked segment script, I used the analytics-node package from segment.
I create an Analytics object right before ReactDOM.render - and then can use it wherever I want :)
Note that this will not work for anyone who uses an add blocker, obviously!
i created one website using drupal. In Drupal i crated content pages in that instance using wisywig editor. now my intention is using this content block outside of drupal. can you anyone please help me how to use this content block outside of drupal (with code or something else).
i mean how to render content outside of drupal instance
Rendering blocks and nodes is straight-forward.
Before you can do either you must initiate the drupal core:
define('DRUPAL_ROOT', getcwd());
require_once DRUPAL_ROOT . '/includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
Using getcwd() assumes you are placing the script in drupal's root.
To display blocks, use block_load():
$blocks[] = block_load('block',$delta); //first block to display
$blocks[] = block_load('block',$delta2); //second block to display
print drupal_render(_block_get_renderable_array(_block_render_blocks($blocks)));
For nodes, there are several approaches. node_view(node_load()) seems to be the cleanest:
print drupal_render(node_view(node_load($nodeId)));
I'm trying to create an NG app where parts can be enabled/disabled dynamically. The idea is to have an "admin" page, where parts of the app can be enabled or disabled, and then see new functionality appear, in the form of an adjusted menu at the top of the page, and matching routes, controllers, etc loaded into the app (I'm using SocketStream w/ NG).
The first step was to add / remove routes dynamically, for which I found a solution at https://stackoverflow.com/a/13173667 - working well, as far as I can tell.
Next, adding items to the menu bar - easy with ng-repeat on ul/li items.
So the app adjusts its menu and recognizes the corresponding route. So far so good.
The problem comes with registering a controller. I'm calling myApp.controller('SandboxCtrl',[...]) with proper args (same as what worked when initialising statically on startup), but the controller does not appear to get loaded or inited properly. Navigating to the newly added route generates errors such as:
Error: Argument 'SandboxCtrl' is not a function, got undefined

I'm currently at a loss on how to proceed. I've not been able to find a solution on the web. The app is too large to put in a jsFiddle, but I can commit the last changes on GitHub if needed.
Questions: is this feasible? what can I do to debug this? any examples I could look at?
EDIT: The code is now at https://github.com/jcw/housemon (needs node/npm/redis). It's easy to reproduce the problem: launch with "npm start", browse to localhost:3333, go to admin tab, click on "jcw-sandbox" and then "Install". Top menu will update with new a "Sandbox" entry. Clicking on that entry generates the error shown above.
Oh, almost forgot: relevant code is in client/code/app/main.coffee and client/code/modules/routes.coffee ...
The answer turns out to be two-fold:
the NG calls were made from SocketStream RPC callbacks, and had to be wrapped in $scope.$apply calls - my bad, didn't know about this SS/NG interaction
the rest of the solution was outlined by #matys84pl - pick up $controllerProvider (and $filterProvider) early on, so they can be called at a later time instead of the normal "app.controller" and "app.filter" members, which don't seem to work anymore later on
Example code in GitHub, I'll link to a specific commit so this answer stays valid:

I want to display particular block on view page. I have added list to show specific view in a particular block as <viewpagename>, but it is not working. How can I show a particular block on a particular view page in Drupal 7?
Long time I didn't touch Drupal, however, if I remember right, after you choose a path for your view, you can add that path to the settings of the block.
so if the view is available on /view-page, add to the block setting "view-page" in the "include" section.
There is a block_views module made specifically for this reason I believe. It's in beta but works rather nicely for Drupal 7:

First time poster here, I'm a designer not skilled at all with php and I have a small issue I don't seem to be able to solve. I'm making a site in drupal 7 using a sub theme on zen.
Btw this is a great CMS, even though people say it's really more a developers CMS. I have no trouble to do what I need using views, rules, display suite etc. So a big thank you for all the developers out there making this such a good CMS. But for this apparently simple problem... no module will help me (I think) and I'm kinda stuck.
So here it is: I'd like to add a subtitle next to the title in all my pages.
So what I did was to add a custom field into the content type basic page (machine name: field_sub_title) which is a simple text field.
I uncommented the following line in my template.php
function mytheme_preprocess_page(&$variables, $hook) {
$variables['sub_title'] = t('field_sub_title');
}
Now my question is how do I load the content of my custom field into that variable?
I know i need to change the second part, but I don't have a clue as into what I need to change this.
Displaying the variable into the the page.tpl.php is something I know about so I only need help with the first part.
{EDIT}
Ok I found how to do this :)
I was looking for a solution in the wrong place. I don't need to change any thing in the template.php file.
Just needed to add this bit of code into my page.tpl.php:
<?php
print $node->field_sub_title['und'][0]['value'];
?>
So I'm posting this here for other Drupal newbies struggling with this....
Your solution may work for now, but there may be a more Drupal-y way to handle a problem like this. If you haven't noticed any problems yet, you may find one or more of the following issues down the road:
Someone who doesn't know php or Drupal theming may need to change the way this works.
If you're like me, you may forget where exactly in code this was implemented.
You may see superfluous markup and/or errors on nodes (content) that do not have this sub-title field (ie. event content not having a sub-title field while basic pages and news articles do).
When you add a field to a content type, it will automatically appear anytime content in that content type is displayed. You should be able to add the sub-title field for your page, event or whatever else you need and have it automatically appear in the markup.
You can 'manage display' of a content type to drag and drop the order for fields to appear. You could take it a step further by using a module like Display Suite to add formatting or layout per-content type.
If you feel like this isn't good enough and the markup for the subtitle must be at the same level as the page title (which is rare), at least add an if statement to make your code check to see if the variable is present before trying to print it. I'd also add a new variable and comments for code readability.
<?php
$subtitle = $node->field_sub_title['und'][0]['value'];
if($subtitle){
print $subtitle;
}
?>
Consider using field_get_items or field_view_value, or at least use the LANGUAGE_NONE constant instead of 'und'
See https://api.drupal.org/api/drupal/modules%21field%21field.module/function/field_get_items/7 and https://api.drupal.org/api/drupal/modules!field!field.module/function/field_view_value/7
This has the added benefit of reducing the number of potential security holes you create.
