In this Tutorial we learn how to make a a custom block and render a form in a block in drupal 8 customization process.

So lets start 

1) Create a basic simple module by create .info.yml file as below:

name: Custom form in Block
description: key2goal example module for form in block
type: module
core: 8.x
package: Custom

2) Now create the form in src/Form/KeyForm.php as below:

Similar to drupal 7, Drupal 8 also provide the logging functionality but little different to use it because the drupal 8 is symphony base architecture, so can use the logger service of drupal 8 to reload your logs on dblog

For Notice type:

<?php
\Drupal::logger('module_name')->notice($message_string);
?>

For Error Type:

his is article is for Drupal 7 to render block in templates and custom blocks using php codes

Actually there is very simple ways to render block pro-grammatically 

1) Module Invoke

$block = module_invoke('module_name', 'block_view', 'delta or machine name of block');
print render($block['content']);

Module invoke is most common way to render a block, above example is self explained or see the below example

In drupal 8 there is easiest way to add the date format is simply go link for your website

"https://www.yourdomain.com/admin/config/regional/date-time"

OR

navigate to "Home  Administration  Configuration  Regional and language"

In the new era the drupal8 twig is introduce, so old basic php drupal hook is not useful in theme templates. Now twig is power under the template and if you want to know the user is logged in or Not you can use the following method in your template like node.html.twig or html.html.twig or page.html.twig etc 

{% if logged_in %}
 !!!! do you stuff !!!
{% else %}
 !!!! do you stuff !!!
{% endif %}

Its Just a simple thing helps to add script, or your static html or dynamic coding 

Happy Coding, Have Fun

Hey guys, 

Sometimes we created the themes template in drupal 7 and we need to render custom blocks and views block to display proper diversion, but I face a problem to render block in multilingual site it show the same in both languages.

So I found the solution, hopes it helps to other also 

$block_id = 2;
$block = block_block_view($block_id);
$block['content'] = i18n_string(array('blocks', 'block', $block_id, 'body'), $block['content']);
print render($block['content']);

Just need to update the $block id with yours.

Similar to Drupal 7, Drupal 8 also gives the customization using theme template, If you want to place a block using programmatically you have following options : 

1) Using the default Drupal method using THEME_preprocess_page,write this function in your mytheme.theme file, See the example below :

 example:

Let we assume we want to use at the page load so, add this is hook_init():

function mymodule_init(){

$token_value = "this is value of your variable";

drupal_add_js(array('mymodule' => array('token' => $token_value)), array('type' => 'setting'));

}

Now get the in your js file, but make sure your js file also preloaded to website via theme.info or any other way ...

If you want to render a node in drupal 7 it is pretty easy, you just a node id or nid of node for doing this:

simply

<?php 
$nid = 13; //use your node nid which you want to render
$nodeview = node_view(node_load($nid));
print drupal_render($nodeview);
?>

You can use this any template like node,page, block, region or field etc.

In Drupal 8 Twig templates give extra power to drupal to add dynamic content in twig style, In this tutorial we can see how we can add the custom menu classes to menu ul li using menu.html.twig.

If you are creating your own theme or custom theme in drupal 8 then to overwrite the menu class we need to override the menu.html.twig template to our theme directory, so copy menu.html.twig form drupal core template to our theme directory

Core template path: [drupal_root]/core/modules/system/templates/menu.html.twig
