Adjust the quantity input values

You are here:

Add code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the Code snippets plugin. Avoid adding custom code directly to your parent theme’s functions.php file as this will be wiped entirely when you update the theme.

Set the starting value, maximum value, minimum value and increment amount.

  /**
  * Adjust the quantity input values
  */
  add_filter( ‘woocommerce_quantity_input_args’, ‘jk_woocommerce_quantity_input_args’, 10, 2 ); // Simple products
   
  function jk_woocommerce_quantity_input_args( $args, $product ) {
  if ( is_singular( ‘product’ ) ) {
  $args[‘input_value’] = 2; // Starting value (we only want to affect product pages, not cart)
  }
  $args[‘max_value’] = 80; // Maximum value
  $args[‘min_value’] = 2; // Minimum value
  $args[‘step’] = 2; // Quantity steps
  return $args;
  }
   
  add_filter( ‘woocommerce_available_variation’, ‘jk_woocommerce_available_variation’ ); // Variations
   
  function jk_woocommerce_available_variation( $args ) {
  $args[‘max_qty’] = 80; // Maximum value (variations)
  $args[‘min_qty’] = 2; // Minimum value (variations)
  return $args;
  }
