How to define multiple blocks in a module?

Question

Thanks to this tutorial, I cam up with this block-generating module:

function myblockmodule_block_info(){
    $block['myadblocks'] = array(
        'info' => t('My first ad blcoks'),
        'cache' => DRUPAL_NO_CACHE,
    );
    return $block;
}

/**
 * Define what our block is going to look like.
 * Implements hook_block_view().
 */
function myblockmodule_block_view($block_key){
    $block = array();

    if($block_key == 'myadblocks'){ //We only want to define the content of OUR block
        //This is the title of the block.
        $block['subject'] = t('First ad block comes here');

        //Define the block content.
        $block['content'] = 'some fancy script comes here';
    }

    return $block;
}

I am wondering how to extend the module to create 2 blocks instead of one?

Answer 1

Simple as:

function myblockmodule_block_info(){
    $block['myadblocks'] = array(
        'info' => t('My first ad blcoks'),
        'cache' => DRUPAL_NO_CACHE,
    );

    $block['myadblocks2'] = array(
        'info' => t('My second ad blcoks'),
        'cache' => DRUPAL_NO_CACHE,
    );
    return $block;
}

/**
 * Define what our block is going to look like.
 * Implements hook_block_view().
 */
function myblockmodule_block_view($block_key){
    $block = array();

    if($block_key == 'myadblocks'){ //We only want to define the content of OUR block
        //This is the title of the block.
        $block['subject'] = t('First ad block comes here');

        //Define the block content.
        $block['content'] = 'some fancy script comes here';
    }
    elseif ($block_key == 'myadblocks2') {
      $block['subject'] = t('Foo');
      $block['content'] = 'var';
    }

    return $block;
}

And clear the caches.

Answer 2

function myblockmodule_block_info(){
    $blocks = array();
    $blocks['myadblocks'] = array(
        'info' => t('My first ad blcoks'),
        'cache' => DRUPAL_NO_CACHE,
    );
    $blocks['myadblocks2'] = array(
        'info' => t('My second ad block'),
        'cache' => DRUPAL_NO_CACHE,
    );
    return $blocks;
}

/**
 * Define what our block is going to look like.
 * Implements hook_block_view().
 */
function myblockmodule_block_view($block_key){
    $block = array();

    if($block_key == 'myadblocks'){ //We only want to define the content of OUR block
        //This is the title of the block.
        $block['subject'] = t('First ad block comes here');

        //Define the block content.
        $block['content'] = 'some fancy script comes here';
    } elseif ($block_key == 'myadblocks2') {

        $block['subject'] = t('Second ad block comes here');

        $block['content'] = 'some fancy script comes here';
    }

    return $block;
}
