• Set filter automatically

  For this you should activate in the plugins tab 'Options' option 'Set filter automatically'.
  And on the shop page and categories pages you will get smth like this
  
  

• Widget

  Widget is more convinient way to represent search forms, because its can be presented on all pages of the site which allow users to start searching from any place of your site.
  You can set widget quickly here: /wp-admin/widgets.php
  
  
  • Additional text before - text where you can put any content before WOOF search form in the widget, for exaple shortcode [woof_search_options]
    
    
  • Redirect to - Redirect link to any page - use it by your own logic. Leave it empty for default behavior.
  • Form AJAX redrawing - Useful when uses hierarchical drop-down for example. Redraws search form without submiting
• By shortcodes -> Read next section please ...

Instead of (also with) reading this documentation you can watch video tutorials here: https://products-filter.com/video-tutorials/

The plugin has 2 basic shortcodes:
[woof sid="auto_shortcode" autohide=0 taxonomies=product_cat:9]
[woof_products per_page=8 columns=3 is_ajax=0 taxonomies=product_cat:9 custom_tpl='woof_tpls/woo_tpl_1.php'] where woof_tpls is folder inside wp theme folder or its child folder

Shortocode [woof] generates search form and has next options:

• sid: here you can set any word without space. You may need it if you want to customize it for your layout using css.
  For example if to set sid 'auto_shortocode' - container of the search form will has css class as 'woof_sid_auto_shortcode' which you can use in your customization
  
  
• autohide - if set this option to '1' - search form will be hidden after page loading and your customers can press button to show it.
  
  
• taxonomies you can define condition where set taxonomy and its term. Do not forget to set the same condition in [woof_products]. Example: [woof is_ajax=1 taxonomies=product_cat:9,12+locations:30,31]
  
• tax_exclude exclude taxonomies from the seacrh form: [woof tax_exclude='pa_size,pa_test']
  
• Additionally user can create custom set of filter-elements using next attributes:
  
  • tax_only - write taxonomies or products slug using comma
  • by_only - write any by-filter-elements there using comma: by_text,by_price,by_sku,by_author,by_onsales,by_instock. Of course firstly user should enable extensions for that by-filter-elements
  Example: [woof tax_only='pa_color,pa_size' by_only='by_sku,by_author']. Use word 'none' if you do not want out any of that 2 types of filter-elements
  
• redirect - allows show results on any another page of the site. Example: [woof redirect='https://www.my_site.com/search_page_results_77']. Ignored in ajax mode as AJAX works with current page DOM!
  
• ajax_redraw - Redraws search form without submiting. Example: [woof redirect="https://www.my_site.com/test-all/" autosubmit=1 ajax_redraw=1 is_ajax=1 tax_only="locations" by_only="none"]
  
• autosubmit - allows autosubmit of the search form even if its disabled in the plugin options page. Example: [woof autosubmit=1]
  

• per_page: products per page
• columns: how many products per row. Usually it is: 2,3 or 4. It depends of your theme ability/functionality and not from the WOOF!
• is_ajax: very power option. You can set it to 1 and your filter generated by [woof] will start works in AJAX mode!
• taxonomies you can define taxonomy-condition there. Do not forget set the same condition in [woof]. Example: [woof is_ajax=1 taxonomies=product_cat:9,12+locations:30,31]
  
• behavior only one value: 'recent'. Example: [woof_products behavior='recent' per_page=12 columns=3]

• tpl_index - index of cutom extension which is template
  
• get_args_only - value 1 or 0, default is 0. Possibility get assembled array of arguments for any purposes. WP_Query request in this case not done ...

So it can help you in your defferent css customizations for your site!

Custom Taxonomies

Hierarchy drop-down

Hint: When WOOF-search IS going on the site in tag body appears CSS class 'woof_search_is_going'. Happens only in non-ajax mode.

Main reccomendation is for dynamic recount -> this feature takes a lot of resources because each recount can take more that 1 sql query to database and this can make site slow. So there is ways to make it fast:

• Do not use it
• Use 'Cache dynamic recount number for each item in filter' in the plugins settings -> tab 'Advanced'. But in this case after you added more posts you will have to clean this cache OR set it cron period for it:
  
  • clean cache automatically hourly
  • clean cache automatically twicedaily
  • clean cache automatically daily
  • clean cache automatically each 2 days
  • clean cache automatically each 3 days
  • clean cache automatically each 4 days
  • clean cache automatically each 5 days
  • clean cache automatically each 6 days
  • clean cache automatically each 7 days
  
  It is depends of how often products-adding on your site ...
• Use cache plugins as WP Super Cache for example. But this way good when your site not in AJAX mode. For AJAX mode better use 'Cache dynamic recount number for each item in filter'
• Use minimum PHP 5.4 or higher! PHP 7.2 is recommend!
• Read FAQ

The plugin has some features which can help you in the customization of the plugin functionality:

• The plugin settings -> tab Advanced -> Code -> textarea 'Custom CSS code'. Here you can add any CSS code you need for your customization
• The plugin settings -> tab Advanced -> Code -> textarea 'JavaScript code after AJAX is done'. You can use it reiniting of any DOM elements if you need it. Useful thing when you uses non standard output for woocommerce products, any dynamic galleries for example ...
• The plugin uses hook 'woof_before_term_name' - you can use it to place any icons before each term of any taxonomy for example!
  if (has_filter('woof_before_term_name')) echo apply_filters('woof_before_term_name', $term, $taxonomy_info);else echo $term['name'];
  This filter is applied in: views\html_types\checkbox.php, views\html_types\radio.php, views\html_types\mselect.php, views\html_types\select.php
  Using variables $term AND $taxonomy_info you can identify each term and taxonomy of it.
• If you need to operate with view (html/css) or functionality of the plugin or any another thing for mobile devices there is JavaScript variable generated by the plugin - woof_is_mobile - which has value 1 if user using mobile device, and 0 if not.
• There is ability to work with the plugin: Display Product for WooCommerce, but to make them friends you will have to do some actions!
• It is possible add auto scroll after ajax searching is done
• In files:
  
  • views\html_types\checkbox.php
  • views\html_types\color.php
  • views\html_types\mselect.php
  • views\html_types\radio.php
  • views\html_types\select.php
  
  implemented filter before foreach: woof_sort_terms_before_out.
  $terms = apply_filters('woof_sort_terms_before_out', $terms, 'select');
  You can apply it for custom sorting on front with different scenarios.
• In shortcode [woof_products] before wp_query implemented next code:
  $wr = apply_filters('woof_products_query', $wr);
  So developer can create callback for wp hook 'woof_products_query' and manipulate with its arguments!
  Look API here: https://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters
  
• Hint: When woof-search IS going on the site in tag body appears CSS class 'woof_search_is_going'
• Filter 'woof_use_chosen' - for any manipulation with enabling chosen js lib for drop-downs. For exampe disable it for mobile view:
  

  			
  			    add_filter('woof_use_chosen', function($is)
  				{
  				    if (wp_is_mobile())
  				    {
  					return false;
  				    }
  
  				    return $is;
  				});
  			
                          

• Filter 'woof_main_query_tax_relations' - manipulations with taxonomies relations in the search query. Read more here https://products-filter.com/hook/woof_main_query_tax_relations/. Here is video with demonstration of the feature.
• Filter 'woof_text_autocomplete_items' - use it to return count of found posts in text of the search textinput of the plugin if autocomplete mode is enabled.
• Use jQuery(document).trigger('woof_ajax_done'); for any js actions after seacrh by AJAX is done.
