Examples
Modify the maximum price range based on a field value.
<?php
/**
* Gravity Perks // GP Price Range // Modify The Maximum Price Range Based On A Field Value
* https://gravitywiz.com/documentation/gp-price-range/
*/
// Update "123" to your form ID and "4" to your field ID.
add_filter( 'gppr_price_range_max_123_4', function( $min ) {
// Update "5" to the field ID whose value should be used as the minimum price range.
$source_field_id = 5;
return (int) $_POST[ 'input_' . $source_field_id ];
} );Set a variable min/max range based on a field value.
Take a base value and calculate a range based on that value. For example, if the base value is 100 and your range is 50, the user could enter a price between $50 and $150.
This example also uses the gppr_price_range_min to handle setting the minimum price range.
