* Hi Ian
* Firstly, great plugin!
* Secondly, I like to make a different icon for each placemark on the map. I saw
you have a coding on the FAQs for this, but Im not sure where to put it in the
edit part of your plugin, and what bits of code to change (Im doing my website
for a uni assignment and still learning code).
* Ive bolded what i think i need to change depending on the category – do I need
to do the below code for each category or can i just build within this? (I assume
the png image below is the icon wanted to be displayed on the map?)
* Help is much appreciated!

* ```
function setBGMPDefaultIconByCategory( $iconURL, $placemarkID )
{
$placemarkCategories = wp_get_object_terms( $placemarkID, 'bgmp-category' );
foreach( $placemarkCategories as $pc )
if( $pc->slug == 'restaurants' )
$iconURL = get_bloginfo( 'stylesheet_directory' ) . '/images/bgmp-default-icon.png';
return $iconURL;
}
add_filter( 'bgmp_default-icon', 'setBGMPDefaultIcon', 10, 2 );
```

* Hi Erin, it’s not a good idea to modify the plugin directly, because then your
changes will be overwritten any time you upgrade. Instead, you can put your changes
inside [a functionality plugin](http://www.doitwithwp.com/create-functions-plugin/).
* If you want to assign icons to multiple categories, you can do within a single
function using a series of if/else statements [or a switch()](http://pastebin.com/hp0FNma1).

* Hi Ian, thanks so much for your reply they were great instructions – however
the category icons still seem not to be working?
* I have added the [bgmp-map categories=”restaurant,winery,accommodation,golf,hot-
air-balloon”] as your installation instructions said.
* When i zipped my php file I also included folders to map the icons
i.e. ‘/images/
marker-icons/food-icon.png’; = (plugin)/images/market-icons/(icon.png file) –
is this correct?
* Do the icons need to be a particular size? I’ve tried both with the size i have
and the size of the existing icon but to no change

* I found the workaround by using the featured image, but if you have time would
like to know where I was going wrong above? thanks!

* Hi Erin, the size doesn’t matter at all. I can’t tell what’s going wrong since
you changed back to using the featured image, but my first guess would be that
the URLs were wrong. You can install [Firebug](http://getfirebug.com/) and check
the Console tab for 404 errors.
* Instead of using relative paths, it’s better to use one of the API functions
to generate an absolute one. If the images are stored in the content directory,
you’d use `wp_uploads_dir()`; if they’re in a theme you’d use `get_stylesheet_directory_uri()`;
and if they’re in a plugin you’d use `plugin_dir()`. You can check [the Codex](http://codex.wordpress.org)
for details on how to use those functions.

* Thanks so much for your help Ian, I think I’m just not understanding the PHP
coding… I will try and look into it if I have time, for what I need it for the
featured image will work ok for now 🙂

* I am also having some problems with this. [I added this following code](http://pastebin.com/hmcde18C)
to my functions.php file — we have 5 different categories of events, for most
I just set the featured image, but I did a test one for Chicago without setting
the featured image and just checking off the category name and it didn’t work.
* Any suggestions?

* dhobeika, if you use Firebug or Chrome Dev Tools you’ll see these errors in the
console log:
* ```
bgmp_createMarker(): OK - Tulsa icon wasn't passed in. functions.js:141
bgmp_createMarker(): IL - Chicago icon wasn't passed in.
```
* If you view the page source and look at the bgmpData.markers array, you’ll see
that the icon values for both are “null”
