By default on search forms you'll get a single 'Search' button. If you wanted to remove the department option and instead have two individual 'For Sale' and 'To Rent' buttons then you can follow the steps below:
Step 1: Remove the Department option
Using our free Template Assistant add on you can customise the fields shown in search forms through a drag-and-drop interface.
Simply edit the form(s) in question and drag the 'Department' field from the 'Active Fields' list to the 'Inactive Fields' list.
Step 2: Override the search form template
Next we need to customise the buttons by editing the search-form.php template. To do this we should first override it. You can read more about overriding templates here, however in summary you should copy:
Step 3: Customise the buttons
Within the newly copied search-form.php template file that now sits in your theme, you should replace the current button:
<input type="submit" value="<?php _e( 'Search', 'propertyhive' ); ?>">
with something like so:
<input type="button" value="<?php _e( 'For Sale', 'propertyhive' ); ?>" onclick="document.ph_property_search.department.value='residential-sales'; document.ph_property_search.submit();"> <input type="button" value="<?php _e( 'To Rent', 'propertyhive' ); ?>" onclick="document.ph_property_search.department.value='residential-lettings'; document.ph_property_search.submit();">
