Advanced Filtering Module

The Advanced Filtering Module is part of the core JReviews package and allows you implement a great looking and powerful filtering solution for your JReviews site. Possible filters include categories, listing types, user & editor ratings, and custom fields.

You can create custom filter forms and we've made it dead-simple to use a single theme and module throughout the site through the use of display conditionals. These conditionals are based on directory, listing type and category and can be applied to individual filters or to a group of filters to simplify the markup code.

The module has an instant update feature so search results are updated on the page without page reloads. It's also mobile ready so it looks and works great on both on desktop and mobile devices.

Configuring the module

Standard fields

The module provides parameters that allow you to enable filters for standard JReviews fields:

• Category Field - Displays a list of categories
• Listing Types Field - Displays a list of listing types. It should not be used together with Category Field filter.
• Keywords Field - Text input. A Keyword Scope setting is also available where you can choose which standard fields will be searched
• User Rating Field - Allows filtering by user rating (i.e. 3 stars & Up).
• Editor Rating Field - Allows filtering by editor rating (i.e. 3 stars & Up).

Custom fields

In addition to filters for standard fields, the module allows you to create filters for custom fields via shortcodes, for example, this shortcode would display a filter for "jr_state" custom field:

[filter name="jr_state"]

Shortcodes can be either placed in the "THEME CUSTOMIZATION" module parameter or to the module's theme file: /views/themes/default/modules/filters.thtml

Shortcodes can have attributes to specify how and when the filter will be displayed, for example with additional attributes we can specify a custom label, make the options display as links and make the field appear only in directories 2 and 10:

[filter name="jr_state" label="State" display_as="link" show_dir="2,10"] 

If you decide you want a different order for the standard fields, or want to add conditionals to them, then you can disable the settings and use a similar shortcode syntax as the one for custom fields.

[filter name="categories" label="Categories" display_as="link" split_list="0"]

[filter name="listing_types" label="Listing Types" display_as="link" split_list="1"]

[filter name="keywords" label="Keywords"]

[filter name="rating" type="user" label="User Rating"]

[filter name="rating" type="editor" label="Editor Rating"]

Keep reading to learn more about the different attributes that can be used for the filter shortcode.

Basic filters & auto detect

Different combinations of settings will result in slightly different behavior of the filters so it's important to read the explanation below:

• Auto detect enabled: then the category and listing type lists should be disabled (not sure if I should do it by default because users may think the settings don't work). The point of auto-detect is that the results will be automatically filtered based on the current page and that would work well with category and detail pages. For directory pages it would just filter by directory initially.
• Auto detect disabled, basic filters used, category and listing type lists hidden: In this scenario, the basic filters are added as hidden inputs. They are checked in this order: category, listing type, directory and only the first one that is not empty is used for filtering.
• Auto detect disabled, basic filters used, category or listing type lists shown: The module will automatically limit the options shown in the category or listing type lists based on the selected values in basic filters.
  • To limit category list options only directory and category filters should be used.
  • To limit listing type list options only the listing type filters should be used. It's hard to limit the categories based on listing type because there can be many top level categories without a listing type.
  • Category and Listing Type filters should not be used together because selecting a listing type will not change the values of the category list.

Available shortcode attributes

Attribute	Description	Values	Default value
name	Name of the custom field - required attribute	i.e. jr_address
label	Title of the filter	any custom text	title of the custom field
placeholder	Placeholder text, used only for text inputs	any custom text
display_as	How the field will be displayed	checkbox, select, link or linkboxed	checkbox
auto_open	Automatically toggles open the filter on page load to display the input or search options	0 or 1	0
show_cat	The filter will be displayed only if specified categories are detected	Comma separated list of category IDs
show_dir	The filter will be displayed only if specified directories are detected	Comma separated list of directory IDs
show_listing_type	The filter will be displayed only if specified listing types are detected	Comma separated list of listing type IDs
hide_cat	The filter will be hidden when the specified categories are detected	Comma separated list of category IDs
hide_dir	The filter will be hidden when the specified directories are detected	Comma separated list of directory IDs
hide_listing_type	The filter will be hidden when the specified listing types are detected	Comma separated list of listing type IDs
split_list	Selected filter options are moved to the top of the list	0 or 1	1
radius_min	Minimum radius for proximity filter. Only works on the proximity search field.	number	10

radius_step	Radius step for proximity filter slider. Only works on the proximity search field.	number	10
radius_default	Default radius for proximity filter. Only works on the proximity search field.	number	10

Grouping shortcodes

A filtergroup shortcode can be used to group individual filters. For example, we can group all restaurant field filters and use a 'show_listing_type' attribute to show them only when a restaurants listing type is detected:

[filtergroup name="Restaurants" show_listing_type="3"]

	[filter name="jr_cuisine" label="Cuisine" display_as="checkbox"]

	[filter name="jr_mealsserved" label="Meals Served"]

	[filter name="jr_restaurantpricerange" label="Price Range" display_as="linkboxed"]

[/filtergroup]

Displaying filters on mobile devices

The Advanced Filters Module has the ability to convert to a "slideout panel" on mobile devices. The regular module becomes hidden on mobile devices and the slideout panel is activated when visitors click the Filters button in list page header. Example of the slideout panel on a mobile device:

The module provides settings that allow you to choose when to convert the regular module into the slideout panel:

Convert to mobile view - Select the breakpoint when to convert the module to slideout panel

Module container class - Specify the CSS class used by the module container so it can be hidden in mobile view

Module title class - Specify the CSS class used by the module title so it can be shown in the slideout panel
