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 :

Facebook is Providing autoposting functionality using website application and provides to display you website content on your facebook page.

But the Question how we can customise that post so it look right on page ?

Answer is Facebook Open Graph Tags.

 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 ...
