This is very similar to the snippet example here here but it allows you to have a custom output function rather then creating a template part.
// Add new block for our singular blog posts
// This allows us to manage it via the customizer under Customize > Blog > Single > Single Layout Elements
function my_add_new_block( $blocks ) {
$blocks['new_block_id'] = __( 'New Block Name', 'total' );
return $blocks;
}
add_filter( 'wpex_blog_single_blocks', 'my_add_new_block' );
// Define the output of our new block
function my_new_block_output( $blocks ) {
// Before defining the output we want to make sure the block is enabled in the Customizer
if ( isset( $blocks[ 'new_block_id' ] ) ) {
// Example 1: Add new block with an anonymous function for the output
$blocks['new_block_id'] = function() {
echo 'test';
};
// Example 2: Add new block with a custom function as the output
$blocks['new_block_id'] = my_function_name();
// Example 3: Add new block with an anonymous function that returns a template part
$blocks['new_block_id'] = function() {
get_template_part( 'my-custom-block-file' );
};
}
// Return blocks
return $blocks;
}
add_filter( 'wpex_blog_single_layout_blocks', 'my_new_block_output' );
