I have a situation where I'd like to post two values to a search query string array from a single checkbox. Because of the design, I can't just add another checkbox.
The checkbox in question looks like so:

```
<input name="wpp_search[property_type][]" value="rental_home" type="checkbox" id="choice_c"/>
<label for="choice_c">For Rent</label>

```

what I now get in the query string is ...

```
{url}?wpp_search[property_type][0]=rental_home 

```

but what I need is to tie two values to that one check so I end up with this:

```
{url}?wpp_search[property_type][0]=rental_home&wpp_search[property_type][1]=building

```

Any simple solutions? There is only one other checkbox that already feeds that array, so I could force this one to be

```
{url}?wpp_search[property_type][0]=rental_home&wpp_search[property_type][2]=building

```
