Car Demon 1.7.0 Released

Car Demon Wicked PowersWe’re proud to announce the release of Car Demon version 1.7.0!

We’ve packed lots of enhancements into this version.

One of the most exciting features are Vehicle Tags. You now have the ability to create tags for your vehicles and then use the new “vehicle_tag” parameter in the [cd_inventory] shortcode to display only vehicles with that tag.

We’ve also added multiple taxonomy support for the shortcode and search query! This means it is now possible to add multiple values to the following fields in the shortcode: year, make, model, condition, body_style, location & vehicle_tag.

For example, let’s say you wanted to show vans and minivans all on the same page using the shortcode. You can now use the following shortcode to do exactly that!

[cd_inventory body_style="van|minivan"]

We’ve also released a new developer’s documentation area with information on all the filters, actions & constants that are currently available. Be sure to check it out: Car Demon Documentation.

Car Demon 1.5.0 released!

car-demon-1.5.0We’re excited to announce the release of Car Demon 1.5.0 and want to thank everyone who beta tested and provided feedback.

The most exciting new feature is an inventory shortcode you can drop in a page, [cd_inventory].

This new shortcode accepts year, make, model, condition, body_style, transmission, location, stock, criteria (keyword search), min_price, max_price, miles (searches vehicles with less than the mileage entered) & show_sold

You can also use the title parameter to add a title to the top of the listings.

You now have the ability to create a page that lists, for example, ford trucks;

[cd_inventory title="Ford Trucks" make="ford" body_style="truck"]

To give you even more power you can assign search forms to the page your shortcode is on and search just those items.

To make sure your search forms point to the correct result page you can set the result_page parameter for the search form widget or use it in the search form shortcode;

[search_form size=1 result_page="the url to your inventory shortcode page"]

In fact we’ve now made this the default on installation. New installs will create a page called ‘Inventory’ and drop both the search form and inventory shortcodes into it.

The default style is fairly plain, but if you’ve created a filter for your inventory items it will be applied here.


If you’d like a professional style we also offer the “Car Demon Pro Shortcode” plugin. Now you can quickly and easily add a professional  responsive inventory layout that you can color match to your theme.


Other changes include minor style changes, admin UI updates, performance tweaks and misc clean up and structuring.

We’ve tried to test it out as fully as possible, but with so many people using Car Demon in so many different ways there’s bound to be an issue or two. If you’ve recently updated and are having an issue please accept our apology and post a comment here so we can investigate the issue and issue patches as needed.

In closing we want to thank everyone for their continued support and look forward to many more updates!

More than just cars!

Did you know Car Demon can be used for selling a wide variety of vehicle types?

Don’t let the ‘Car’ in Car Demon fool you!

If you sell Boats, RVs, Semi Trucks, Planes or even Rocket Ships then you can use Car Demon.

Car Demon was designed to be a “vehicle sales” PlugIn and isn’t limited to just cars.

Sure, right out of the box everything is setup for your typical Car Dealership but with a few changes to your settings it can be a WordPress PlugIn for Motorcycle Dealerships or ATV Dealerships.

If you’re building a site for any kind of vehicle sales then chances are Car Demon can handle it.

Car Demon Not Cars

We even have an add-on PlugIn designed to help make it even easier; Car Demon Not Cars

You don’t have to have the “Not Cars” PlugIn to sell other vehicle types, but it does include a few extra functions that switch around the verbiage in the admin area so it makes more sense to anyone updating your site.

If you’re building a site for a client then we highly recommend grabbing a copy of Car Demon Not Cars, your client will thank you for it.

How do I use Car Demon for selling other types of vehicles?

We’re glad you asked! The first thing you want to do is change the URL slug under Car Demon settings.

Car Demon Custom URL Option

Let’s say you’re selling boats. Change the slug to something like boats-for-sale. Then re-save your permalinks to update the URL. Now your vehicle listings will appear under

What about vehicle options?

Obviously the vehicle options for cars are different from the options for a boat. So we’ve made it as easy as possible for you to change these options to match your vehicle type.

Go to your Car Demon Settings and look for the button that say “Edit Vehicle Option Tabs”.

Tab options button

On the next page you have the ability to change the labels for the default Specs, or even hide them. You also have the ability to add or remove option groups and even the options themselves.

Car Demon Vehicle Options

Now that you have your options updated to match your vehicle type you should be good to go.

But the Admin area still says Cars For Sale!

Yes it does and this can be annoying or even confusing for anyone updating the vehicles. It just doesn’t feel right and if you’re building a site for a client they might give you a hassle over it.

This is one of the great things the “Car Demon Not Cars” PlugIn can help you with!

After you install it you’ll have an admin area that lets you change the labels in the admin area. Now you have the ability to make the admin menu item say “Boats For Sale” and give your client some peace of mind.

Car Demon Not Cars

What have we learned?

Car Demon is more than just a WordPress PlugIn for car sales.

  1. It’s a WordPress PlugIn for Boats
  2. It’s a WordPress PlugIn for RVs
  3. It’s a WordPress PlugIn for Planes
  4. It’s a WordPress PlugIn for Motorcycles
  5. It”s a WordPress PlugIn for Semi Trucks
  6. It’s a WordPress PlugIn for ATVs
  7. It”s a WordPress PlugIn for Rocket Ships!

If you’re building a website for any kind of vehicle sales then Car Demon should be the first tool in your arsenal.

Car Demon – Wicked Powers for MORE than just Car Dealers!

Version 1.4.0 has been released

We’ve now released version 1.4.0 of the Car Demon PlugIn.

This version has a couple long awaited features, including the ability to change the default URL of your vehicle listings! That’s right, you can now change to something something else like or

Car Demon Custom URL Option

We’ve also added a few new filters for all you designers and developers out there.

car_demon_single_car_filter – Filter the default single car page
car_demon_display_car_list_filter – Filter the vehicle results loop

These two filters will let you use the default templates and customize their display any way you want.

Here’s a quick example on how to use them:

add_filter('car_demon_single_car_filter', 'my_car_demon_single_car',10,2);
function my_car_demon_single_car($content,$post_id) {
     //= $content contains the default listing, you can add content, replace parts of it or build it completely new!
     //= $post_id is the vehicle's Post ID
     $content = '<h1>This is my new single car page!</h1>';
     $car = car_demon_get_car($post_id);
     // use print_r() to see everything car_demon_get_car returns
     // print_r($car);
     $car_title = $car['title'];
     $content .= $car_title;
     return $content;

The car_demon_display_car_list_filter works the same way as car_demon_single_car_filter and uses the same 2 arguments. Now you have the ability to custom tailor the default templates to make them exactly the way you want without needing to create an entire template page for your theme.

We also made several smaller changes to help improve the code base and make Car Demon more efficient. A full list of all changes for 1.4.0 is below.

Change Log for Version 1.4.0

* The cars-for-sale url slug can now be changed on settings page;
* This means your inventory can now be;
* It also means you can do or something similar
* Added car_demon_single_car_filter so developers can filter default single car pages
* add_filter(‘car_demon_single_car_filter’, ‘my_car_demon_single_car’,10,2);
* add_filter(‘car_demon_display_car_list_filter’, ‘my_car_demon_car_list’,10,2);
* Then to filter add function my_car_demon_single_car($content, $post_id) etc.
* Added Top mobile menu option
* Added snippet to make sure form css and js don’t load on Admin pages
* Replace time and date code on contact form widget to match other forms
* Moved Custom sales affiliate code to only run on front side of site
* Updated days and years variable in finance form
* Changed search form url to get_bloginfo(‘wpurl’);
* Added css class similar_cars_box_title

Changing Vehicle Options and Labels

Let’s say you want to change some of the default vehicle options. Instead of Stock # you want it called just stock and instead of mileage you want it to say miles and since you only sell Buick’s you want to hide the made.

Car Demon has several robust features that let you customize vehicle options and labels.

First go to your Car Demon’s settings page and find the Tab Options. Now click on the “Edit Vehicle Option Tabs” button.

Tab options button

You’ll see a section for each of the tabs. Expand the Specs Tab and you’ll find options for renaming standard fields or even hiding them.

You’ll also see a section where you can add or remove non-standard options.

Edit Car Demon Tabs

You can add or remove additional groups for each tab. If you open the Safety Tab you’ll see it has several groups of options.

You can add or remove groups as needed. If you remove a group or option from a group it doesn’t remove that information for the vehicle if it’s been set. If you recreate a group with the same name and add the same list of options then Car Demon will show the data on the vehicle again.

Car Demon Tabs

After you update your information your options should appear on the vehicle edit screen and be reflected on the vehicles.

We hope this post gives you a little more information on how you can customize Car Demon to fit your needs.

Car Demon Shortcodes

The Car Demon PlugIn comes with several shortcodes that you can use to add Car Demon content to your pages.

The code for them can be found in plugins/car-demon/includes/car-demon-shortcodes.php

The first set of shortcodes are for the forms that come with Car Demon.

If you look on the bottom of the Car Demon settings page you’ll see a list of them along with some buttons you can use to create a page with the basic shortcode dropped in.


The shortcodes for the forms have several arguments you can use with them to control how they’re displayed.

send_to – set this to the location name in Car Demon Settings
popup_id – if you set this to a number or a single word name it will hide the form and replace it with a button that pops opens the form into a lightbox. If you want to include multiple forms in a page then just make sure you give each of them a unique popup_id.
popup_button – this will change the text of the popup button if you have set a popup_id for the form.

So if you used [contact_us popup_id=”1″ popup_button=”Email Us Now”] it will add a button to your page that says “Email Us Now” and will pop open the contact form when clicked.

If you had a location named “Bill’s Cars” and a location named “Sam’s Cars” and you wanted to create a popup service form for each of them on the same page you’d add the following shortcodes

[service_quote send_to=”Bill’s Cars” popup_id=”1″ popup_button=”Get a Service Quote from Bill”]
[service_quote send_to=”Sam’s Cars” popup_id=”2″ popup_button=”Get a Service Quote from Sam”]

Other Shortcodes

People often ask if there is a shortcode to insert inventory into any page. You can do this with our Advanced Search PlugIn – it lets you put a dynamic json driven inventory into any page.

There are a few other shortcodes that come with the Free Car Demon PlugIn that you might find handy.




[search_form] – comes with one argument, “size”. If you set it to “0” it will return the small narrow search form, set it to “1” it will give you the small wide search form and if you set it to “2” it will give you the full search form.

So to add a full sized search form to a page you’d add [search_form size=”2″].

[search_box] – adds a keyword vehicle search box to your page. Setting the argument “button” you can control what the buttons says. Setting the argument “message” will change the text that appears in front of the search form.

This [search_box button=”Search Cars” message=”Search by Keyword”] would create a search box that says “Search by Keyword” right before it and a button that says “Search Cars”.


The [highlight_staff staff_id=”1″] shortcode must be used with the staff_id argument. You must create a user for each staff person, make them subscribers. After you create them visit their edit user page and fill in all of the Car Demon settings, including their staff position and contact information. You can also use the argument ‘contact_button’ to change what the contact form button says.

The last shortcode is [staff_page] this will display the entire staff in their corporate order. ie. General Manager first, Sales Staff below. It follows the order of the staff positions given on the user profile pages.

We hope this helps you understand the shortcodes native to the Car Demon PlugIn and will give you a few ideas on how you can structure your pages and content.

You can check out our commercial PlugIns for Car Demon to learn about other shortcodes and features they can give you.

New Demos Added

 We’ve set up a few demo sites so you can see Car Demon in action.

Each demo site has a small pre-loaded inventory with one photo on each vehicle. Only a minimal amount of information has been added to the inventory, just enough to let you see some of the possibilities.

We’ve seen some sites created by our users that just blow us away. All it takes is a little creativity and you can build a lead generating machine that will leave the competition in the dust.

Version 1.3.3 has been released

car-demons-1.3.1It’s been 10 months since that last update to Car Demon. The last year has been a busy one and we’ve worked hard on making lots of changes.

The biggest change is the new “Content Replacement” feature that makes Car Demon compatible with a much wider range of themes, right out of the box.

There have been lots of changes under the hood too. Hopefully those changes will only be noticed as an increase in speed and performance.

You might also notice that we’ve split from – they’re great people but it simply made better sense to take back control of the PlugIn so we can give it and the add-ons the full attention it deserves.

In closing we want to thank everyone for their support and look forward to bringing you even more wicked powers!

All About Car Demon

The CarDemon PlugIn was a labor of love created by a workaholic IT Administrator and a community of hundreds of volunteers.

It would be impossible to list the number of people who write code, beta test features, provide support, write themes, write plugins, sell services and more. This community of people knows who they are and for each one we give thanks and hope they take pride in what they helped to create.
