With IDX+, you can use variables such as %%city%% that get replaced with the relevant information.

But what if you want a field that isn’t a default field, such as the name of the apartment complex? Often, this is defined as Tract (accessible using %%tract%%).

Add the following code to your active theme’s functions.php file.

Add one replacement variable

add_filter('the_content', 'add_complex_park_to_idx_data', 21);

function add_complex_park_to_idx_data($content) {
	global $wp;

	if(!empty($wp->idx_plus)) {
		$supplemental = IDX_Plus::get_global('supplemental');

		if($supplemental && isset($supplemental['Complex/Park'])) {
			$wp->idx_plus['complex'] = $supplemental['Complex/Park'];
		}
	}

	return $content;
}

Add all available replacement variables

This piece of code will make all data in the Additional Details section available using replacement variables. If there is a field named “Master Bedroom Dimensions,” it will be available using %%master-bedroom-dimensions%%.  Read more...
