(Advanced) Only show choices in the Search Bar that exist in entries
If you have a Country field in your form and you only have entries representing five countries, you may want to only show those five countries in a front-end Search Bar instead of hundreds of countries.
To limit searchable drop-down fields to only values that have been submitted, add this filter:
add_filter( 'gravityview/search/sieve_choices', '__return_true' );
If you want to limit this behavior to specific Views and specific form fields, modify this code:
// Only show used choices in entries for View ID 4 and Field ID 6 add_filter( 'gravityview/search/sieve_choices', function( $sieve, $filter, $context ) { if ( 4 === $context->view->ID && 6 === (int) $filter['field'] ) { return true; } return $sieve; }, 10, 3 );
Note: This will match both the choice label and the choice value.
