Sorry if this is a dumb question, but here goes. I have succesfully created a page utilizing the api, finding products based on a particular keyword. It's coded in PHP and a part of my wordpress site. I set some price filters in the php code using one of examples from the tutorials. Like this: $filterarray = array( array( 'name' => 'MaxPrice', 'value' => '100000', 'paramName' => 'Currency', 'paramValue' => 'USD'), array( 'name' => 'MinPrice', 'value' => '500', 'paramName' => 'Currency', 'paramValue' => 'USD'), ); I would like to create a few buttons to make this page a bit more interactive, so a user can filter the price themselves. What's best way to create a few buttons to do this and pass the value back to the array? Thanks!
