Are you using EE3 or EE4?

Hi Zoe,

Yes it’s possible to add your own custom message shortcodes. While we don’t currently have step by step developer documentation that shows how to register new message shortcodes, the Event Espresso 4 ticketing add-on registers its own message shortcodes via the plugin API. I can recommend stepping through the code in the ticketing add-on to learn how to make your own messages shortcodes in a little plugin.

It turns out that Event Espresso 4 core also uses the same API to register new shortcodes. You’ll find examples in EE_Caf_Messages.class.php.

Hi Zoe,

Only shortcodes that are specifically registered for messages can be used in messages.

Hi Zoe E,

There’s basically 2 steps to registering a new shortcode with the EE Messages system. Firstly you register the shortcode and where it can be used, here is an example of how you would do that:

function register_new_tony_shortcodes( $shortcodes, EE_Shortcodes $lib ) {

	if ( $lib instanceof EE_Datetime_Shortcodes ) {
		$shortcodes['[TONYS_SHORTCODE]'] = _('This is Tonys Custom Shortcode!');
	}

	return $shortcodes;
}
add_filter( 'FHEE__EE_Shortcodes__shortcodes', 'register_new_tony_shortcodes', 10, 2 );

That function hooks into the EE Message shortcodes and adds ‘[TONYS_SHORTCODE]’ to the EE_Datetime_Shortcodes.

Then you need to tell EE what to do with the shortcode when it finds it within the message. We do that by adding shortcode a parser. Here is an example of how you add a parser:

function register_new_tony_shortcodes_parser( $parsed, $shortcode, $data, $extra_data, EE_Shortcodes $lib ) {
	if ( $lib instanceof EE_Datetime_Shortcodes  && $data instanceof EE_Datetime ) {
		if ( $shortcode == '[TONYS_SHORTCODE]' ) {
			
			return $data->ID();

		}
	}
	return $parsed;
}
add_filter( 'FHEE__EE_Shortcodes__parser_after', 'register_new_tony_shortcodes_parser', 10, 5 );

We are hooking into the shortcodes after EE has done it’s thing and parsing our shortcode.

$parsed is the currently parse content and must be returned (or you’ll have nothing to send)
$shortcode is the current shortcode to be parsed.
$data is the current object passed to the library.

So we check if we are currently within the EE_Datetime_shortcodes library:

if ( $lib instanceof EE_Datetime_Shortcodes )

If so we want to find our specific shortcode:

if ( $shortcode == '[TONYS_SHORTCODE]' )

In this case I’m just returning the ID of the current datetime:

return $data->ID();

But you will be using that to pull venue info from your custom table and returning that information instead.

Here’s a gist containing both those functions as its easier to read:

Does that help?

Hi all, Thanks for the code above, very very useful. I’ve created my shortcode but am struggling with testing it – I’ve just placed an order but no email confirmation has arrived. Also when I view the receipt on the website (the one thats linked to on the order confirmation screen) I get these errors – are the two things related? Could my shortcode be causing this?

Also is there a way to test the short code without placing a full order. It’d be nice to be able to test it more quickly to iron out any bugs before testing it full in the email.

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘register_new_get_custom_venue_dates’ not found or invalid function name in /home/devhrtrainingco/public_html/wp-includes/plugin.php on line 213

Thanks!

Hi Tony, thanks for your help on this. I’ve spotted why the first error is occuring but not sure about the second one, the shortcode is being registered exactly as your example above (just with the names changed) so I pressume its coming from this function:

function register_new_get_custom_venue_dates_parser( $parsed, $shortcode, $data, $extra_data, EE_Shortcodes $lib ) {
	if ( $lib instanceof EE_Datetime_Shortcodes ) {
		if ( $shortcode == '[get_custom_venue_dates]' ) {

				global $wpdb;

				$thevenues = $wpdb->get_results("SELECT DISTINCT evm.VNU_address, evm.VNU_address2, evm.VNU_city, evm.VNU_zip FROM ".$wpdb->prefix."esp_venue_meta evm 
					INNER JOIN ".$wpdb->prefix."custom_esp_date_venue cdv ON cdv.VNU_ID = evm.VNU_ID 
					WHERE cdv.DTT_ID_ID = '" . $data->ID() . "'");

				$output = "";
				foreach ( $thevenues as $thevenue ) :
					$output = $output.$thevenue->VNU_address."<br />";
					$output = $output.$thevenue->VNU_address2."<br />";
					$output = $output.$thevenue->VNU_city."<br />";
					$output = $output.$thevenue->VNU_zip."<br><br>";
				endforeach;

				return $output;	
		}
	}
return $parsed;
}

but I’m not sure what I need to do to ensure it returns my data as an array?

Thank you 🙂

Thanks Tony, I’ll give that a go now.

Here are both my functions 🙂 http://pastebin.com/x2pfeJS7

That’s because your using a shortcode you have registered within EE_Datetime_Shortcodes within the main content, EE_Datetime_SHortcodes are not valid within the main content section.

You need to use that shortcode within the Datetime_list section – http://take.ms/QOJHm

I’ve just pasted both your functions into my functions.php file, swapped out the return for just a string – http://take.ms/K5nzX.

Then tested that within the messages and it worked fine.

Obviosuly I can’t set your other code as the query won’t work but was your eventually just returning a string it should work.

Have you tried returning a var_dump() of $thevenues?

You can do that using output buffering or even using var_export, have a read here:

http://stackoverflow.com/questions/139474/how-can-i-capture-the-result-of-var-dump-to-a-string

Then see if $thevenues actually has values.

Can I ask what the problem was?

Which links are these? Can you link me to the page?

Did you replace the URLs manually? I remember from your other thread you mentioned replacing the URLs though phpMyAdmin.

Can you link me to the page so I can view this please?

Have you flushed your Permalinks?

Go to Dashboard -> Settings -> Parmalinks

Make no changes and save the settings.

If that doesn’t work go to Event Espresso -> General Settings -> Critical pages.

Then save the settings there and retest.

It uses the WP core function get_permalink() to build those links. The view cart link is built using the reg_page_url() function within EE core, which is just:

public function reg_page_url() {
	if ( ! $this->reg_page_url ) {
		$this->reg_page_url = get_permalink( $this->reg_page_id ) . '#checkout';
	}
	return $this->reg_page_url;
}

So it seems get_permalink() is returning your old URL, so WordPress (not EE) still thinks its on the old url.

If you look within Dashboard -> Settings -> General.

Are your WordPress URL and Site URL values setup using the dev domain?

It could also be a plugin/the theme filtering get_permalink to use your old URL.
