This gist is in response to this forum thread:

Installation

Create Form Inputs

Navigate to:

1. Dashboard -> Properties -> Settings -> Developer
2. In Property Attributes create two rows for search from and search to
3. Give both Search Input of Dropdown Selection with values of:

0,100,200,300,400,500,600,700,800

Use This Code

There are 2 ways to use this code, one is the best option but slightly more technical, the other is quick and messy but will break when you update WP Property

1. Preferred option: Create a child theme of denali and in your child themes function.php file add the above code (start file with <?php and a new line). More on creating child themes: http://codex.wordpress.org/Child_Themes#How_to_Create_a_Child_Theme
2. Add the above exactly code as is to the end of wp-content/themes/denali/functions.php. Please note if you take this option you will have to re-insert this code EVERY time WP Property plugin or Denali theme is updated.

Usage

When you create the 2 inputs above, in Dashboard -> Properties -> Settings -> Developer, under the name of the input will be a similar name with _ instead of spaces. For example, if you name the input Price From then the input name will be price_from.

Using both those input names, place them in the above code where it says price_from_per_month and price_to_per_month respectively.

Example

Say I create two inputs called From Price and Two Price then the input names will be from_price and to_price, the above code will look like:

define('SPRP_SEARCH_FROM_KEY', 'from_price');
define('SPRP_SEARCH_TO_KEY', 'to_price');

Thanks for the solution but for example if i need search properties of 1,000,000 and more? how i can add this value opcion and that the search works, thanks fo the help

Thanks Daithi, where could I call the function from in another theme, if you would like to tell it?
