Filters a value that will be written to a Cookie or the localStorage.

The {key} part in the hook name is the sanitized variable-name (all lower case, dashes changed to underscores).


(string) The value that will be saved to a Cookie or localStorage.
(string) Name of the entry. This will be part of the Cookie name or the localStorage object key.


This filter is called inside DiviArea.Utils.setLocalData().


// Example 1: Output data to the console before it will be saved.
DiviArea.addFilter( 'set_data', function( value, key ) {
    console.log('Saving local variable', key, 'with value', value);
    return value;

// Example 2: Disable local data
DiviArea.addFilter( 'set_data', function( value, key ) {
    return false;


The setLocalData() method will decide, whether to write a Cookie or to save data to the localStorage instead.

When this filter returns boolean false, then no entry is saved in the localStorage (and no Cookie will be changed)
