Filter: bricks/filter_element/populated_options

The bricks/filter_element/populated_options PHP filter allows you to modify the populated options of Filter – Select, Filter – Radio, and Filter – Checkbox elements before they are rendered into HTML. (@since 2.0.2)

This is useful if you want to:

• Add/remove certain options
• Reorder options (based on complicated custom requirement)
• Change display text or values

Example:

The following example removes the “biography” option from a filter element with the ID uzehuy:

/**
 * $options is an array of options that are populated by the element
 * 'value' is the value of the option
 * 'text' is the display text of the option
 * 'is_all' exists and is true if the option is the "All" option
 * 'is_placeholder' exist and is true if the option is a placeholder option
 */
add_filter( 'bricks/filter_element/populated_options', function( $options, $element ) {
  if ( $element->id === 'uzehuy' ) {
    // Remove the options that value is 'biography'
    $options = array_filter( $options, function( $option ) {
      return $option['value'] !== 'biography';
    } );
  }

  return $options;
}, 10, 2 );
