Custom default value tags not working

Hey Evan, that’s super helpful!

I’ve pasted the same exact new code and the new tag appeared on the list.
I cannot test the actual pre-population because we don’t have a log in system on our website.

What I’m specifically trying to do is pre-populate the forms using the WP plugin URL Params.

The problem with all the MailChimp form plugins I’ve come across with is that they don’t give me any control over the HTML. And that’s crucial because of the way the shortcodes are treated in HTML attributes since WP 4.2.3 update:

Starting in the WordPress 4.2.3 security auto-update, you can no longer include shortcodes in HTML attributes. Previous to this WordPress update, you could set a field value like this: <input type=”text” name=”firstname” value=”[urlparam param=’FirstName’]”>. Now you have to set it like this: <input type=”text” name=”firstname” [urlparam attr=”value” param=’FirstName’]> or [urlparam htmltag=”input” type=”text” name=”firstname” attr=”value” param=”FirstName” /]. If you are still using this shortcode the old way, unfortunately, WordPress simply won’t process the shortcode and will return back the full shortcode text unprocessed.

Would it be possible to do something like this via PHP or other means in your plugin? FYI, I don’t know PHP, but I know basic HTML.

Your help is much appreciated!
If more Plugin Authors responded that fast and were so helpful as you are, the world would be a better place 🙂

I see Evan responding to other issue threads, but not this one. Perhaps that’s because it’s marked as “resolved”?

Please help! I don’t know whether I should be putting hope in making it work with this plugin or building an HTML MailChimp form from scratch.

I’m just really afraid that the HTML code rendered on the website will look like <input type=”text” name=”firstname” value=”[shortcode]”>, and in this instance the URL Params shortcodes, or any other shortcodes for that matter, won’t work.

Is the query string in the URL the same each time?

You mean if it’s going to have the same structure? If so, then yes. I’m just trying to pre-populate 2, maybe 3 fields. Most people will visit that page through the custom URL, but some might somehow find it/go to it without any URL customization.

Let’s say I’d just want to use the shortcode [urlparam param=’FirstName’].

Thank you so much for your help! We can’t wait to get our referral campaign going!

That worked, thanks a lot! You guys are really great.

However, when I added the same code but with all the “YIKES_Example” changed (I want to pre-populate 2 different fields), I got an error:

Fatal error: Cannot redeclare add_new_pre_defined_tags() (previously declared in /nas/wp/www/staging/tasklabels/wp-content/themes/customizr-child-theme/functions.php:61) in /nas/wp/www/staging/tasklabels/wp-content/themes/customizr-child-theme/functions.php on line 100

(line 100 being the very beginning of the second (copied) code snippet)

Here is the code I’ve pasted:

<?php

function add_new_pre_defined_tags( $available_tags ) {
	// define a new array, with our default tag data (note: to create more than one, simply copy and paste what is below and alter the values)

	);
	return $available_tags; // return the new tags
}

function process_URL_param_plugin_shortcode_tag( $tag ) {
	// set up a conditional so we only parse the tag we need
	if( $tag == '{email_URL}' ) {
		return stripslashes( do_shortcode( '[urlparam param="email"]' ) );
	}
	// return the tag
	return $tag;
}

function add_new_pre_defined_tags( $available_tags ) {
	// define a new array, with our default tag data (note: to create more than one, simply copy and paste what is below and alter the values)
	$available_tags[] = array(

		'title' => 'Referred by' // title of the link (on hover, used for accessibility purposes)
	);
	return $available_tags; // return the new tags
}

/*

add_filter( 'yikes-mailchimp-process-default-tag', 'process_URL_param_plugin_shortcode_tag' );
function process_URL_param_plugin_shortcode_tag( $tag ) {
	// set up a conditional so we only parse the tag we need
	if( $tag == '{referred_by}' ) {
		return stripslashes( do_shortcode( '[urlparam param="referredby"]' ) );
	}
	// return the tag
	return $tag;
}

Edit: Actually I’ll need to pre-populate 3 fields.

Thanks a lot, that seems to be working perfectly!
