Developer's Guide
The Addon Helper Class is essentially a wrapper designed to facilitate greatly the development of addons. It contains all the methods you need to add new filters, post type, markers, map layout and more.Just call the methods,the Addon Helper does the work for you.
Description :
LocateAnything tags are pseudo-shortcodes of the form : |nameOfTag| , ex : |MyAddon_field_animal_owned|
They are used in the navlist and tooltip template editors. They symbolize a piece of data and will be substituted by their value at runtime.
This method allows you to define new custom tags.
Args :
[array] $arr_tags : array of tags. Form expected: $arr_tags = array(field name => Tagname);
[string] $scope : The scope of the filters : a post type, "user" or "all"
[string] $getDataCallbackFn : callback function name, gets the datas for passed field and marker ID
[string] $addon_name : Addon name, no space or special char
Example :
This will create a tag |Animal_owned| for the field MyAddon_animal_owned .
The new tag appears in the backoffice, in the "Tooltips & Navlist" tab.
You can now, if you want to, define a filter on that tag using Locate_Anything_Addon_Helper::define_filters
$tags = array ('MyAddon_field_animal_owned'=>sanitize_key('Animal owned');
Locate_Anything_Addon_Helper::define_custom_tags($tags,'all',$getDataCallbackFn,$addon_name)Example of callback function : This function fetches the data from various external functions( 'get_bogus_user_data' and 'get_status') and returns the appropriate field
public static function get_vars($field,$id){
if($field=='MyAddon_status') $r = get_status($id);
else {
$p=get_bogus_user_data($id); // returns array('Animal_owned'=>'cat','eye_color'=>'blue','age'=>22)
$r = $p[$field];
}
return $r;
}Description :
LocateAnything in its core version allows you to use any taxonomy as a filter.
In case you need to search on something else than taxonomies like, for example a custom field or a LocateAnything tag, this method allows you to define new filters.
Args :
[array] $arr_filters : array of filters. Form expected: $arr_filters = array(field name => array( 'name'=> filter caption,'values'=>array(field values)));
[string] $scope : The scope of the filters : a post type, "user" or "all"
[string] $getDataCallbackFn : callback function name, gets the datas for passed field and marker ID
[string] $addon_name : Addon name, no space or special char
Example :
This will create a filter for the custom field MyAddon_animal_owned with the values 'cat','dog' and bird'.
The new filter appears in the backoffice, in the "Filters" tab. Just tick its checkbox to activate it.
$filters = array ('MyAddon_field_animal_owned'=>array( 'name' =>'Animal owned','values'=>array('cat','dog','bird'));
Locate_Anything_Addon_Helper::define_filters($filters,'all',$getDataCallbackFn,$addon_name)Asset methods are used to add new assets : new overlays, marker icons, map layout, navlist or tooltip preset, etc...
