I created one custom module, it will create one custom block when it is installed. I want to display it on "product" content type only. Can I do the same with programmatically. It'll save my time. Here is my code.

<?php
function my_module_block_info() {
    $blocks = array();

    $blocks['my_module_config'] = array(
            'info' => t('My Module'),
    );
    return $blocks;
}


/**
 * Implements hook_block_view().
 */
function my_module_block_view($delta = '') {
    $block = array();

    switch ($delta) {
        case 'my_module_config':
            $my_module_form = drupal_get_form('my_module_form');
            $my_module_form = drupal_render($my_module_form);
            $block['subject'] = '';
            $block['content'] = $my_module_form;
            break;
    }
    return $block;
}
?>

  • No options available to set content type custom. You need to go for admin >> Structure >> Blocks configure and at bottom you find content type you would like to display. – vgoradiya Aug 3 '15 at 13:21
  • @VirangJethva to format the code of a question/answer you need to add 4 spaces before the text – M a m a D Aug 4 '15 at 7:09

This code should work for you

function my_module_block_info() {
  $blocks = array();
  $blocks['my_module_config'] = array(
    'info' => t('My Module'),
    'status' => TRUE,
    'region' => 'content',
  );
  return $blocks;
}


/**
 * Implements hook_block_view().
 */
 function my_module_block_view($delta = '') {
 $block = array();

 switch ($delta) {
   case 'my_module_config':
     $block['subject'] = '';
     $node = menu_get_object();
     if (isset($node->type) && $node->type == 'product') {
       $my_module_form = drupal_get_form('my_module_form');
       $my_module_form = drupal_render($my_module_form);
       $block['content'] = $my_module_form;
     }
     else {
       $block['content'] = '';
     }
     break;
  }
  return $block;
}
  • Thanks Andrew, but this won't work. – Virang Jethva Aug 4 '15 at 6:11

I got one solution but It's weird, It's working by this way.

function example_install() {
// Install our custom block visibility settings per node type
$query = db_insert('block_node_type')

->fields(array('type', 'module', 'delta'))
->values(array(
  'type' => 'my-node-type', // content-type
  'module' => 'example', // My module name
  'delta' => 'my-block-delta', // Same delta used in hook_block_info
))
->execute(); 
}

Clearly you know how to do it using admin UI in block configuration, If you don't want to use this option, Why don't you load the block in Product node pages instead of assigning it's visibility to this content type in the module?


Did you try hook_block_list_alter ?

This hook allows you to add, remove or modify blocks in the block list. The block list contains the block definitions, not the rendered blocks. The blocks are rendered after the modules have had a chance to manipulate the block list.

The Show block for specific content type programmatically can be helpful. The hook_block_list_alter_example.php is another example.

  • Hi Drupalist, I'm creating one custom module, it'll create one block and when it is installed then it will assigned to one product content type. I want to do these all process when it is installed. – Virang Jethva Aug 3 '15 at 13:25

  • Yes I tried hook_block_list_alter. – Virang Jethva Aug 3 '15 at 14:08

As I can see, the Drupal core save the block content types setting in function node_form_block_admin_configure_submit(). I copied the code from node.module file. So I copied it and made my one here:

  // Say I have two blocks want to show on 'article' content type.
  $my_blocks = array(
    // Block 1: module is 'views' and delta is 'views-block-1'.
    array(
      'type' => 'article',
      'module' => 'views',
      'delta' => 'views-block-1',
    ),
    // Block 2: module is 'webform' and delta is 'client-block-1'.
    array(
      'type' => 'article',
      'module' => 'webform',
      'delta' => 'client-block-1',
    ),
  );

  // Insert settings into 'block_node_type' table.
  $query = db_insert('block_node_type')->fields(array('type', 'module', 'delta'));
  foreach ($blocks as $block) {
    $query->values(array(
      'type' => $block['type'],
      'module' => $block['module'],
      'delta' => $block['delta'],
    ));
  }
  $query->execute();

Notice: Above code should only run once. I putted it into my module update script(my_module.install). Otherwise you may need to add some checking to prevent duplicated records in 'block_node_type' table.
