Using the Divi Code Snippet Module from a Shortcode

My Divi Code Snippet Module lets you easily display source code snippets in your Divi Builder layouts. However, there may be times you want to add a code snippet to a page when you don't have the Divi Builder enabled on that page. It can be done by using the module's shortcode.

Like all Divi modules, the code snippet module is represented internally in your posts by a shortcode. Here's an example of such a shortcode:

[et_pb_dmb_code_snippet admin_label="My Title" _builder_version="3.0.82" title="My Title" style="default" linenums="off" usetabwidth="off" border_style="solid" box_shadow_position="outer"]PD9waHAgZWNobyAiaGVsbG8gd29ybGQhIjsgPz4=[/et_pb_dmb_code_snippet]

You'll notice in the shortcode above that there is a "garbled" bit of text (PD9waHAgZWNobyAiaGVsbG8gd29ybGQhIjsgPz4=). This is actually the source code the module will display, but it is base64 encoded to stop it from being altered by either Divi or WordPress. If you enter this into an online base64 decoder and hit decode you'll get back the original source code, which in this case is:

<?php echo "hello world!"; ?>

Add your own source code to the shortcode, you can paste your source code into a base64 encoder. This will convert your source code into a garbled base64 string, which you can then us in the shortcode given above.

Another way to generate the shortcodes is to create a page in the Divi Builder, add your code snippet module, save the page as a draft and then temporarily disable Divi / the Divi Builder (e.g. by switching themes, or deactivating the Divi Builder plugin. If you then reload the page edit screen and switch to the "Text" tab of the default editor, you'll see the shortcode. Obviously, since this method requires disabling the theme, it is best to do it on a test site rather than a live site.

Creating an Alias for the Shortcode

If you'd like to simplify things, you might consider creating a new shortcode that generates the code snippet module shortcode, preconfigured with your choice of design, and which takes care of the base64 encoding for you so that you can enter code directly. Here is an example of the PHP code to create such a shortcode:

// Create alias for code snippet module shortcode
add_action('wp_loaded', 'db_codesnippet_shortcode_init', 11);
add_shortcode('codesnippet', 'db_codesnippet_shortcode_wrapper');

function db_codesnippet_shortcode_init() {
	$module = new DMB_Module_Code_Snippet;
	add_action('wp_head', array($module, 'output_user_css'));		
	add_action('wp_head', array($module, 'output_user_js'));
	add_action('wp_head', 'test_css');	
	$module->module_used();
}
function db_codesnippet_shortcode_wrapper($atts, $content="") {
	return do_shortcode('[et_pb_dmb_code_snippet admin_label="My Title" _builder_version="3.0.82" title="My Title" style="default" linenums="off" usetabwidth="off" border_style="solid" box_shadow_position="outer"]'.base64_encode(html_entity_decode($content)).'[/et_pb_dmb_code_snippet]');
}

Now you can use the new shortcode in your posts like so:

[codesnippet]<?php echo "hello world"; ?>[/codesnippet]

If using this aliasing technique, I suggest checking your code snippets for correctness once generated. By delaying the base64 encoding, there is the possibility that some code samples may not display correctly.
